  • Internet‐based treatment of stress urinary incontinence: 1‐
           and 2 years results of a randomised controlled trial with focus on pelvic
           floor muscle training
    • Authors: M Sjöström; G Umefjord, H Stenlund, P Carlbring, G Andersson, E Samuelsson
      Abstract: Objectives To evaluate the long‐term effects of two non‐face‐to‐face treatment programmes for stress urinary incontinence (SUI) based on pelvic floor muscle training (PFMT). Subjects and Methods Randomised controlled trial with online recruitment of 250 community‐dwelling women aged 18‐70 years with SUI ≥1/week. Diagnosis based on validated self‐assessed questionnaires, 2‐day bladder diary, and telephone interview with a urotherapist. Consecutive computer‐generated block‐randomisation with allocation by an independent administrator to 3 months of treatment with either an Internet‐based treatment programme (n=124) or a programme sent by post (n=126). Both interventions focused mainly on PFMT; the Internet group received continuous e‐mail support from a urotherapist, whereas the postal group trained on their own. Follow‐up was performed after 1 and 2 years via self‐assessed postal questionnaires. The primary outcomes were symptom severity (International Consultation on Incontinence Questionnaire Short Form, ICIQ‐UI SF) and condition‐specific quality of life (ICIQ‐Lower Urinary Tract Symptoms Quality of Life, ICIQ‐LUTSqol). Secondary outcomes were the Patient's Global Impression of Improvement, health‐specific quality of life (EQ‐Visual Analogue Scale), use of incontinence aids, and satisfaction with treatment. There was no face‐to‐face contact with the participants at any time. Analysis was based on intention‐to‐treat. Results We lost 32.4% (81/250) of participants to follow‐up after 1 year and 38.0% (95/250) after 2 years. With both interventions, we observed highly significant (p0.8) for symptoms and condition‐specific quality of life after 1 and 2 years, respectively. No significant differences were found between the groups. The mean changes (SD) in symptom score were 3.7 (3.3) for Internet and 3.2 (3.4) for postal (p=0.47) after 1 year, and 3.6 (3.5) for Internet and 3.4 (3.3) for postal (p=0.79) after 2 years. The mean changes (SD) of condition‐specific quality of life were 5.5 (6.5) for Internet and 4.7 for postal (6.5) (p=0.55) after 1 year, and 6.4 (6.0) for Internet and 4.8 (7.6) for postal (p=0.28) after 2 years. The proportions of participants perceiving they were much or very much improved were similar in both intervention groups after 1 year (Internet 31.9% (28/88), postal 33.8% (27/80) p=0.82), but after 2 years significantly more participants in the Internet group reported this level of improvement (39.2% (29/74) vs. 23.8% (19/80), p=0.03). Health‐specific quality of life improved significantly in the Internet group after 2 years (mean change EQ‐VAS 3.8 (11.4), p=0.005). We found no other significant improvements in this measure. One year after treatment, 69.8% (60/86) of participants in the Internet group and 60.5% (46/76) of participants in the postal group reported that they were still satisfied with the treatment result. After 2 years, the proportions were 64.9% (48/74) and 58.2% (46/79), respectively. Conclusion Non‐face‐to‐face treatment of SUI with PFMT provides significant and clinically relevant improvements in symptoms and condition‐specific quality of life 1 and 2 years after treatment.

      Abstract: Objective To evaluate the accuracy of combined multi‐parametric magnetic resonance imaging (mp‐MRI) and transperineal template‐guided mapping biopsy (TTMB) for identifying lobes with significant prostate cancer (PCa) for the application of hemi‐ablative focal therapy (FT). Patients and Methods From January 2012–January 2014, 89 consecutive patients aged ≥40 with PSA ≤15 underwent in sequential order: mp‐MRI, TTMB and radical prostatectomy (RP) at a single centre. Analysis was performed on 50 patients that met consensus guidelines for FT. Lobes were stratified into lobes with significant cancer (LSC), insignificant cancer (LIC) and no cancer (LNC). Using histopathology at RP, the predictive performance of combined mp‐MRI+TTMB in identifying LSC was evaluated. Results The sensitivity, specificity and positive predictive value (PPV) for mp‐MRI+TTMB for LSC was 97%, 61% and 83% respectively. The negative predictive value (NPV), the primary parameter of interest, for mp‐MRI+TTMB for LSC was 91%. Of the 50 patients, 21 had significant unilateral disease on mp‐MRI+TTMB. Two of these 21 patients had significant bilateral disease on RP not identified on mp‐MRI+TTMB. Conclusions In candidates for FT, mp‐MRI and TTMB provides a high NPV in the detection of lobes with significant cancer. This article is protected by copyright. All rights reserved.

  • Telemetric monitoring of bladder function in female Göttingen
           minipigs
    • Authors: Nadine D Huppertz; Ruth Kirschner‐Hermanns, Rene H Tolba, Joachim O Grosse
      Abstract: Objectives To generate real‐time radio‐telemetric urodynamic reference data of maximum detrusor pressure (Pdet max), maximum flowrate (Qmax) and estimated grade of infravesical obstruction as well as for duration of detrusor contraction (DOC), in female Göttingen minipigs and to describe translational aspects of the use of Göttingen minipigs for urological research. Material and Methods In five female Göttingen minipigs, a telemetric transmitter was implanted and 24 h measurements in metabolic cages were performed. Through operator based analysis, synchronized real‐time radio‐telemetric cystometric data with flowmetric data and video sequences were used to determine voiding detrusor contractions (VC) and non‐voiding detrusor contractions (NVC). Furthermore data from telemetric natural filling cystometry from free‐moving and restricted maintenance were compared for potential difference. Results Median maximum detrusor pressure (Pdet max) of VC's was 120.6 cm H2O (21.0‐ 370.0 cm H2O) (median [range]) and, therefore, significantly different from Pdet max of NVC's (64.60 cm H2O [20.4 to 280.6 cmH2O]). Intra‐individual comparison of minipig data revealed great differences in voiding contractions. Effects of limited moving on VC's were analyzed and showed significantly higher Pdet max and lower DOC than in free‐moving maintenance. Conclusion The presented data can be used for the development of telecystometric implanted minipig models ‐ to investigate changes of detrusor function like under‐ or overactivity and might serve as model for bladder changes occurring with iatrogenic bladder outlet obstruction (BOO) or different therapeutical options for overactive bladder (OAB). Radio‐telemetric real‐time natural filling and voiding cystometries are feasible, reproducible in not anesthetized minipigs of free or limited moving and can give new insights in understanding circadian behaviour, physiological and pathological bladder function.

  • Intravesical Gemcitabine in combination with Mitomycin C as salvage
           treatment in recurrent non‐muscle invasive bladder cancer
    • Authors: Patrick A. Cockerill; John J. Knoedler, Igor Frank, Robert Tarrell, R. Jeffrey Karnes
      Abstract: Objectives To evaluate oncologic outcomes after combination intravesical therapy with Gemcitabine (GC) and Mitomycin C (MMC), in the setting of recurrent non‐muscle invasive bladder cancer (NMIBC), after failure of prior intravesical therapy. Patients and Methods We retrospectively identified patients with recurrent NMIBC after prior intravesical therapy, who refused or were not candidates for cystectomy, between 2005 and 2011. GC and MMC were sequentially instilled weekly for six to eight weeks. Data was collected regarding patient demographics, bladder cancer history, and number and type of intravesical therapies prior to GC/MMC, Outcomes evaluated included time to recurrence and/or progression after GC/MMC. Recurrence free outcomes were estimated using the Kaplan Meier method, and cox proportional hazard regression models were used to test the association of clinicopathologic features with outcomes. Results 27 patients were identified, 23 with high risk (high grade or CIS) and four with intermediate risk (multifocal or recurrent low grade) disease. All patients received prior intravesical therapy, and 17 patients (63%) received multiple courses. Twenty four patients were treated with BCG. Median disease free survival of all patients was 15.2 months (1.7 months‐39.3 months). Seventeen patients (63%) developed recurrent bladder cancer, a median of 15.2 months after therapy. One patient progressed to muscle invasive disease five months after treatment, and one patient developed metastatic disease 22 months after treatment. Three patients went on to cystectomy. Ten patients (37%) had no evidence of disease at last follow up, with a median follow up of 22.1 months. Conclusion The combination of intravesical GC and MMC may offer durable recurrence free survival to some patients with recurrent NMIBC who are not candidates for, or refuse, cystectomy.

  • Does the Addition of Targeted Prostate Biopsies to Standard Systemic
           Biopsies Impact Treatment Management for Radiation Oncologists'
    • Authors: Mitchell Kamrava; John V. Hegde, Narine Abgaryan, Edward Chang, Jesse D. Le, Jason Wang, Patrick Kupelian, Leonard S. Marks
      Abstract: Objectives To study the management impact that MRI‐guided targeted prostate biopsies could provide relative to using only non‐targeted systematic biopsies in men with clinically‐localized prostate cancer (CaP). Subjects/Patients and Methods A consecutive series of untreated men undergoing Artemis (MRI‐ultrasound fusion) biopsies between March 2010 and June 2013 was evaluated in this retrospective, IRB‐approved study. Fusion biopsy included MRI targeted and systematic sampling at the same session. 3‐Tesla multiparametric MRI was performed at a median of 2 weeks prior to biopsy. Patients were included if > 1 systematic core revealed CaP. The impact of the information obtained from targeted versus systematic biopsies was studied on the following: Gleason Score (GS), NCCN risk reclassification, cancer core length, percent of core positive for tumor involvement, and percent positive biopsy cores. Results The study sample included 215 men (mean age=66 +/‐8 years). Median PSA was 6.0 (range = 0.7‐181 ng/ml). The mean number of total biopsy samples was 18 (12 systematic and 6 targeted samples). 34/215 men (16%) had a higher GS on targeted vs. systematic biopsy. 21/183 men (12%) were stratified into a higher NCCN risk group when incorporating targeted biopsy GS results. 18/101 men (18%) were upgraded to intermediate‐ or high‐risk from the low‐risk group. Among the 34 men whose cancer severity was upgraded, increases in cancer core length, percent involvement, and percent of cores involved were all statistically significant (p < 0.01). Conclusion Targeted prostate biopsy provided information about GS, NCCN risk, and tumor volume beyond that obtained in systematic biopsies, specifically increasing the proportions of intermediate‐ and high‐risk men. Such patients may be recommended for additional treatments (pelvic nodal irradiation or hormonal therapy). The appropriateness of changing treatment because of targeted biopsy results is still unclear. This article is protected by copyright. All rights reserved.

    • Authors: Shunichi Namiki; Koji Mitsuzuka, Yasuhiro Kaiho, Shigeyuki Yamada, Hisanobu Adachi, Shinichi Yamashita, Hideo Saito, Akihiro Ito, Haruo Nakagawa, Misa Takegami, Yoichi Arai
      Abstract: Objective To perform a longitudinal investigation of the correlation between functional recovery and sex hormone levels after radical prostatectomy (RP). Patients and methods A total of 72 consecutive men undergoing RP between January 2012 and June 2013were prospectively included and serially followed postoperatively for comparative analysis. They underwent measurements of luteinizing hormone (LH) and total testosterone (TT) levels prior to surgery and 3 and 12 months postoperatively. They filled out a health‐related quality of life questionnaire before and at 1, 3, 6, and 12 months after surgery. Results The mean LH level increased from 4.28 U/L at baseline to 5.53 U/L at 3 months and remained high at 12 months after RP (both p

      Abstract: Objective To evaluate our long‐term outcomes of robotic assisted laparoscopic (RAL) upper urinary tract (UUT) reconstruction. Materials and Methods Data from 250 consecutive patients undergoing RAL UUT reconstruction including pyeloplasty with or without stone extraction, ureterolysis, ureteroureterostomy, ureterocalicostomy, ureteropyelostomy, ureteral reimplantation and buccal mucosa graft ureteroplasty was collected at a tertiary referral center between March 2003 and December 2013. The primary outcomes were symptomatic and radiographic improvement of obstruction and complication rate. The mean follow‐up was 17.1 months. Results Radiographic and symptomatic success rates ranged from 85% to 100% for each procedure with a 98% radiographic success rate and 97% symptomatic success rate for the entire series. There were a total of 34 complications; none greater than Clavien grade 3. Conclusion RAL UUT can be performed with few complications, with durable long‐term success, and is a reasonable alternative to the open procedure in experienced robotic surgeons.

      Abstract: Objective To build a predictive model of urinary continence recovery following radical prostatectomy that incorporates magnetic resonance imaging parameters and clinical data. Patients and Methods We conducted a retrospective review of data from 2,849 patients who underwent pelvic staging magnetic resonance imaging prior to radical prostatectomy from November 2001 to June 2010. We used logistic regression to evaluate the association between each MRI variable and continence at 6 or 12 months, adjusting for age, body mass index (BMI), and American Society of Anesthesiologists (ASA) score and then used multivariable logistic regression to create our model. A nomogram was constructed using the multivariable logistic regression models. Results In total, 68% (n=1,742/2,559) and 82% (n=2,205/2,689) regained function at 6 and 12 months, respectively. In the base model, age, BMI, and ASA score were significant predictors of continence at 6 or 12 months on univariate analysis (p

  • The Utility and Significance of Ureteral Frozen Section Analysis During
           Radical Cystectomy
    • Authors: Raj Satkunasivam; Brian Hu, Charles Metcalfe, Saum B. Ghodoussipour, Manju Aron, Jie Cai, Gus Miranda, Inderbir Gill, Siamak Daneshmand
      Abstract: Objective To assess the utility of routine frozen section analysis (FSA) of ureters at the time of radical cystectomy (RC) for urothelial cancer (UC), and the long‐term outcomes of adverse ureteral pathology. Patients and Methods Pathological data on 2,047 patients undergoing RC for UC with routine FSA of ureters (01/1971 – 12/2009) were analyzed. Univariate and multivariable logistic and cox‐proportional hazards models were utilized to determine the risk of upper tract urothelial cancer (UTUC) recurrence, local recurrence and overall survival in those identified as having adverse pathology (severe atypia/CIS or UC) at time of FSA. Results Adverse pathology was identified by FSA in 178 patients (8.6%). FSA displayed poor sensitivity in identifying adverse pathology (59.1%), which was improved in patients with pre‐operative CIS (68.0%). After a median follow‐up of 12.4 years (IQR 1.9‐10.1 years), 28 patients (1.4%) developed UTUC recurrence. There were no uretero‐enteric anastomotic recurrences. Adverse pathology on FSA was associated with UTUC recurrence on univariate analysis (HR: 6.2, 95% CI: 2.9‐13.5), however, 54% (15 of 28) of patients with UTUC recurrence had benign ureteral FSA on initial sectioning. Adverse pathology on FSA was not independently associated with the risk of local recurrence (HR: 1.08, 95% CI: 0.61‐1.89) or overall survival (HR: 1.12, 95% CI: 0.94‐1.35) in multivariate models. Conclusions Ureteral FSA has poor sensitivity and may be marginally improved in pre‐existing CIS. UTUC recurrence is rare and can occur despite negative FSA. Our data question the utility of routine frozen section analysis of the distal ureteral margin at the time of radical cystectomy. This article is protected by copyright. All rights reserved.

  • Guideline of Guidelines: Kidney Stones
    • Authors: Justin B. Ziemba; Brian R. Matlaga
      Abstract: Acute flank pain is a common presenting symptom with nephrolithiasis being the most frequent etiology.[1] The overall prevalence of kidney stones in the United States is estimated at approximately 9%.[2] Given the prevalence of this disease, it is frequently encountered in routine clinical practice. Therefore, several professional organizations have developed evidence‐based guidelines for the evaluation, surgical management, and medical treatment of patients with nephrolithiasis. The purpose of this article is to summarize these guidelines with references to the strength of evidence. This article is protected by copyright. All rights reserved.

  • A review of detrusor overactivity and the overactive bladder after radical
           prostate cancer treatment
    • Authors: N Thiruchelvam; F Cruz, M Kirby, A Tubaro, C Chapple, K D Sievert
      Abstract: There are various forms of treatment for prostate cancer. In addition to oncologic outcomes, physicians and increasingly patients are focusing on functional and adverse outcomes. Symptoms of overactive bladder (OAB), including urinary frequency, urgency, and incontinence, can occur regardless of treatment modality. This article examines the prevalence, pathophysiology, and options for treatment of OAB after radical prostate cancer treatment. OAB seems to be more common and severe after radiation therapy than surgical therapy and even persisted longer with complications, suggesting an advantage for surgery over radiotherapy. Because OAB that occurs after radical prostate surgery or radiotherapy can be difficult to treat, it is important that patients are made aware of the potential development of OAB during counselling before decisions regarding treatment choice are made. To ensure a successful outcome of both treatments, it is imperative that clinicians and non‐specialists enquire about and document pre‐treatment urinary symptoms and carefully evaluate post‐treatment symptoms.

      Abstract: Objective To determine whether patients with normal preoperative renal function, but who possess medical risk factors for CKD, experience poorer renal function post partial nephrectomy (PN) for renal cell carcinoma (RCC) compared to those without risk factors. Materials We investigated the effect of age, hypertension (HTN) and diabetes (DM) on estimated glomerular filtration rate (eGFR) in 488 consecutive operations for RCC performed between 2005 and 2012 at six Australian tertiary referral centres. 156 patients underwent PN and 332 patients underwent radical nephrectomy (RN). We used chi‐square and binary logistic regression to analyse new‐onset CKD, and multiple linear regression to investigate determinants of postoperative eGFR. Results The development of new‐onset eGFR

           the risk of end‐stage renal disease (ESRD)
    • Authors: Stanley A. Yap; Antonio Finelli, David R. Urbach, George A. Tomlinson, Shabbir M.H. Alibhai
      Abstract: Objective To assess whether radical nephrectomy (RN) compared with partial nephrectomy (PN) for the treatment of renal cell carcinoma (RCC) is associated with greater risk of end‐stage renal disease (ESRD). Patients and Methods We performed a population‐based, retrospective cohort study using linked administrative databases in the province of Ontario, Canada. We included individuals with pathologically confirmed RCC diagnosed between 1995 and 2010. Cox proportional hazards, propensity score, and competing risks models were used to assess the impact of treatment choice. The primary outcome was ESRD. Secondary outcomes included overall mortality, myocardial infarction, and new‐onset chronic kidney disease (CKD). A modern cohort of patients (2003–2010) was analysed separately. Results We included 11 937 patients, of whom 2107 (18%) underwent PN. The median follow‐up was 57 months. In the full cohort, type of surgery was not associated with the rate of ESRD, whereas PN was associated with a decreased likelihood of ESRD compared with RN in the modern cohort using a multivariable proportional hazards model [hazard ratio (HR) 0.44, 95% confidence interval (CI) 0.25–0.75) or propensity score modelling (HR 0.48, 95% CI 0.27–0.82). PN was also associated with a lower risk of new‐onset CKD (HR 0.48, 95% CI 0.41–0.57). Conclusions Although it is well‐known that RN is associated with more CKD than PN, we provide the first direct evidence that PN is associated with less ESRD requiring renal replacement therapy than RN in a modern cohort of patients with RCC.

  • Pattern of invasion is the most important prognostic factor in patients
           with penile cancer submitted to lymph node dissection and pathological
           absence of lymph node metastasis (pN0)
    • Authors: Giuliano Aita; Walter Henriques Costa, Stenio Cassio Zequi, Isabela Werneck Cunha, Fernando Soares, Gustavo Cardoso Guimaraes, Ademar Lopes
      Abstract: Objectives Penile carcinoma (PC) is a rare neoplasm in European countries, of which the presence of lymph node metastasis is the most important prognostic factor. Few studies have examined PC patients with histologically negative nodes (pN0). The aim of this study was to identify the prognostic factors in a cohort of pN0 PC patients. Subjects and Methods One hundred one patients with PC met the inclusion criteria—47 (46.5%) patients underwent bilateral inguinal lymph node dissection, and 54 (53.5%) subjects underwent bilateral inguinopelvic lymph node dissection. Variables that had a prognostic impact on survival rates in the univariate analysis were selected for multivariate survival analysis. Results The cohort cancer‐specific survival (CSS) and overall survival (OS) rates were 88.1% and 52.5%, respectively. Histological grade and pattern of invasion were the only features to significantly impact survival rates in the univariate analysis. The CSS and OS rates in patients with pushing versus infiltrating patterns of invasion were 98.0% versus 78.4% (p=0.003) and 70.0% versus 35.3% (p=0.005), respectively. Pattern of invasion was the only independent predictor of survival. Patients with infiltrating invasion had a higher probability of death from cancer (HR 11.5, P = 0.019) and overall death (HR 2.3, P = 0.007) compared with those with a pushing invasion pattern. Conclusions The presence of an infiltrating pattern of invasion is the most important predictor of survival in PC patients. We encourage other centers to confirm our findings that the pattern of invasion is an important prognostic factor in patients with PC and pN0 disease.

  • Final Quality of Life and Safety Data for patients with mCRPC treated with
           Cabazitaxel in the UK Early Access Programme (NCT01254279)
    • Authors: A Bahl; S Masson, Z Malik, AJ Birtle, S Sundar, RJ Jones, ND James, MD Mason, S Kumar, D Bottomley, A Lydon, S Chowdhury, J Wylie, JS Bono
      Abstract: Background Cabazitaxel is a novel taxoid developed to overcome resistance to other taxanes. The 2010 TROPIC trial demonstrated improved survival for cabazitaxel compared with mitoxantrone in metastatic castration resistant prostate cancer (mCRPC) after previous docetaxel chemotherapy. However, concerns regarding safety (particularly neutropenic and cardiac complications) remained and quality of life (QOL) was not assessed. Objective The UK Early Access Programme (EAP) was part of an international phase IIIb/IV trial set up to facilitate access to cabazitaxel and to record detailed safety data. In the UK a specific amendment enabled formal QOL evaluation. Design, Setting and Participants 112 patients participated at 12 UK Cancer Centres. All had mCRPC with disease progression during or after docetaxel. Intervention Patients received cabazitaxel 25mg/m2 every 3 weeks with prednisolone 10mg daily for up to 10 cycles. Safety assessments were performed prior to each cycle and QOL recorded at alternate cycles using the EQ5D‐3L questionnaire and visual analogue scale (VAS). Outcome measures and statistical analysis Safety profile was compiled following completion of the EAP and QOL measures analysed to record trends. No formal statistical analysis was carried out. Results and Limitations The incidences of neutropenic sepsis (6.3%), grade 3 and 4 diarrhoea (4.5%) and grade 3 and 4 cardiac toxicity (0%) were low. Neutropenic sepsis episodes though low occurred only in patients who did not receive prophylactic G‐CSF. There were trends to improved VAS and EQ5D‐3L pain scores during treatment. Conclusions The UK EAP experience indicates that cabazitaxel may improve QOL in mCRPC and represents an advance and useful addition to the armamentarium of treatment for patients whose disease has progressed during or after docetaxel. In view of the potential toxicity, careful patient selection is important. Patient Summary We recorded detailed information about side effects and quality of life in 112 patients with advanced prostate cancer receiving cabazitaxel chemotherapy. We found that side effects were less severe than expected and, importantly, many patients’ quality of life and pain symptoms improved during treatment.

  • Safety and efficacy of mirabegron as add‐on therapy in patients with
           overactive bladder treated with solifenacin: a postmarketing,
           open‐label study in Japan (MILAI study)
    • Authors: Osamu Yamaguchi; Hidehiro Kakizaki, Yukio Homma, Yasuhiko Igawa, Masayuki Takeda, Osamu Nishizawa, Momokazu Gotoh, Masaki Yoshida, Osamu Yokoyama, Narihito Seki, Akira Okitsu, Takuya Hamada, Akiko Kobayashi, Kentarou Kuroishi
      Abstract: Objective To examine the safety and efficacy of mirabegron as add‐on therapy to solifenacin in patients with OAB. Patients and Methods This multicenter, open‐label, Phase IV study enrolled patients ≥20 years old with OAB, as determined by an overactive bladder symptom score (OABSS) total score of ≥3 points and a Question 3 OABSS of ≥2 points, who were being treated with solifenacin at a stable dose of 2.5 or 5 mg once daily for at least 4 weeks. Study duration was 18 weeks, comprising a 2‐week screening period and a 16‐week treatment period. Patients meeting eligibility criteria continued to receive solifenacin (2.5 or 5 mg once daily), and additional mirabegron (25 mg once daily) for 16 weeks. After 8 weeks of treatment, the mirabegron dose could be increased to 50 mg if the patient's symptom improvement was not sufficient, he/she was agreeable to the dose increase, and the investigator judged that there were no safety concerns. Safety assessments included adverse events (AEs), laboratory tests, vital signs, 12‐lead electrocardiogram (ECG), QT corrected for heart rate using Fridericia's correction (QTcF) interval and post‐void residual (PVR) volume. Efficacy endpoints were changes from baseline in OABSS total score, overactive bladder questionnaire short form (OAB‐q SF) score (symptom bother and total health‐related quality of life [HRQL] score), mean number of micturitions/24 h, mean number of urgency episodes/24 h, mean number of incontinence episodes/24 h, mean number of urgency incontinence episodes/24 h, mean volume voided/micturition, and mean number of nocturia episodes/night. Patients were instructed to complete the OABSS sheets at week –2, 0, 8 and 16 (or at discontinuation), OAB‐q SF sheets at week 0, 8 and 16 (or at discontinuation), and patient micturition diaries at week 0, 4,8,12 and 16 (or at discontinuation). Results Overall incidence of drug‐related TEAEs was 23.3%. Almost all TEAEs were mild or moderate. The most common TEAE was constipation, with similar incidence in the groups receiving a dose increase to that observed in the groups maintained on the original dose. Changes in post‐void residual volume, QTcF interval, pulse rate, and blood pressure were not considered to be clinically significant and there were no reports of urinary retention. Significant improvement was seen for changes in efficacy endpoints from baseline to end of treatment (EOT) in all groups (patients receiving solifenacin 2.5 or 5 mg + mirabegron 25 or 50 mg). Conclusions Add‐on therapy with mirabegron 25 mg once daily for 16 weeks, with an optional dose increase to 50 mg at week 8, was well tolerated in patients with OAB treated with solifenacin 2.5 mg or 5 mg once daily. Significant improvements from baseline to EOT in OAB symptoms were observed with combination therapy with mirabegron and solifenacin. Add‐on therapy with mirabgron and an antimuscarinic agent such as solifenacin may provide an attractive therapeutic option.

  • Sensory evoked potentials of the bladder and urethra in middle‐aged
           women: the effect of age
    • Authors: Flavia Gregorini; Stephanie Knüpfer, Martina D. Liechti, Martin Schubert, Armin Curt, Thomas M. Kessler, Ulrich Mehnert
      Abstract: Objectives To investigate feasibility, reproducibility and age dependency of sensory evoked cortical potentials (SEPs) after electrical stimulation of different localizations in the lower urinary tract (LUT) in a cohort of middle‐aged healthy women. Subjects and methods In a group of ten healthy middle‐aged women (mean height: 165±5cm; mean age: 43±6 years), electrical stimulation (0.5 and 3Hz) was applied to bladder dome, trigone, proximal and distal urethra. SEPs were recorded at the Cz electrode with reference to Fz. All measurements were repeated three times with an interval of three to five weeks. Current perception thresholds (CPT), SEP latencies and amplitudes were analysed. Results were compared to a group of younger women published previously. Results LUT SEPs demonstrated 2 positive (P1, P2) and 1 negative peak (N1). The mean N1 latency was 108.9±7.8ms, 116.2±10.7ms, 113.2±13.4ms, and 131.3±35.6ms for bladder dome, trigone, proximal and distal urethra, respectively. N1 latencies – except for the distal urethra ‐ were significantly shorter compared to younger women. Taking all data, i.e. young and middle‐aged women, into account, there was a significant negative correlation between the variable age and CPT/dome (r = ‐0.462, p = 0.04) and N1 latency/dome (r = ‐0.605, p = 0.005) and a significant positive correlation between the variable age and N1P2 amplitude/dome (r = 0.542, p = 0.014). Conclusion LUT‐SEPs can be induced in middle‐aged women with reliable N1 responses. Unexpectedly, N1 responses reveal a shortening with increasing age particularly when compared to younger women. Changes in sensory afferents may be explained by age related qualitative reorganizations within the urothelium and suburothelium potentially altering afferent nerve excitability and may have an impact on the development of non‐neurological LUT disorders (e.g. overactive bladder) in women.

  • Penile lengthening and widening without grafting according to a modified
           sliding technique
    • Authors: Paulo H. Egydio; Franklin E. Kuehhas
      Abstract: To present the feasibility and safety of penile length and girth restoration based on a modified “sliding technique” for patients suffering from severe ED, significant penile shortening with or without Peyronie's disease. Materials and Methods Between January 2013 and January 2014, 143 patients underwent our modified “sliding technique” for penile length and girth restoration and concomitant penile prosthesis implantation. It is based on three key elements: 1) the sliding maneuver for penile length restoration, 2) potential complementary longitudinal ventral and/or dorsal tunical incisions for girth restoration, and 3) closure of the newly created rectangular bow‐shaped tunical defects with Buck's fascia only. Results 143 patients underwent the procedure. The etiologies of penile shortening and narrowing were PD in 53.8%, severe ED with unsuccessful intracavernosal injection therapy in 21%, post‐radical prostatectomy 14.7%, androgen deprivation therapy, with or without brachytherapy or external radiotherapy, for prostate cancer in 7%, post‐penile fracture in 2.1%, post‐redo‐hypospadias repair 0.7%, and post‐priapism in 0.7%. In cases of ED and PD, the mean deviation of the penile axis was 45° (range, 0‐100°). The mean subjective penile shortening reported by patients was 3.4 cm (range, 1‐7 cm), and shaft constriction was present in 53.8%. Malleable penile prostheses were used in 133 patients and inflatable penile prostheses were inserted in 10 patients. The median follow‐up was 9.7 months (range, 6‐18 months). The mean penile length gain was 3.1 cm (range, 2‐7 cm). No penile prosthesis infection caused device explantation. The average IIEF score increased from 24 points at baseline to 60 points at the six‐month follow‐up. Conclusion Penile length and girth restoration based on our modified “sliding technique” is a safe and effective procedure. The elimination of grafting saves operative time and consequently, decreases infection risk and costs associated with surgery.

  • Cigarette smoking during external beam radiation therapy for prostate
           cancer is associated with an increased risk of prostate
           cancer‐specific mortality and treatment‐related toxicity
    • Authors: Emily Steinberger; Marisa Kollmeier, Sean McBride, Caroline Novak, Xin Pei, Michael J. Zelefsky
      Pages: n/a - n/a
      Abstract: Objective To evaluate whether a history of smoking or smoking during therapy after external beam radiotherapy (EBRT) for clinically localised prostate cancer is associated with increased treatment‐related toxicity or disease progression. Patients and Methods Of 2358 patients receiving EBRT for prostate cancer between 1988 and 2005, 2156 had chart‐recorded smoking histories. Patients were classified as ‘never smokers’, ‘current smokers’, ‘former smokers’, and ‘current smoking unknown’. Variables considered included quantity of tobacco use in pack‐years, duration of smoking, and, for former smokers, how long before initiation of RT the patient quit smoking, when available. The median EBRT dose was 8100 Gy and the median follow‐up was 95 months. Toxicity was graded according to the National Cancer Institute's Common Terminology Criteria for Adverse Events. Results Current smoking significantly increased the risks of both prostate‐specific antigen relapse [hazard ratio (HR) 1.4, P = 0.02] and distant metastases (HR 2.37, P < 0.001), as well as prostate cancer‐specific death (HR 2.25, P < 0.001). Multivariate analysis showed that smoking was also associated with increased risk of EBRT‐related genitourinary toxicities (current smoker, HR 1.8, P = 0.02; former smoker, HR 1.45, P = 0.01). Smoking did not increase gastrointestinal toxicity. Conclusions Current smokers with prostate cancer are at increased risk of biochemical recurrence, distant metastasis, and prostate cancer‐related mortality after definitive RT to the prostate. Current and former smokers, regardless of duration and quantity of exposure, are at an increased risk of long‐term genitourinary toxicity after EBRT. Oncologists should encourage patients to participate in smoking‐cessation programmes before therapy to potentially lower their risk of relapsing disease and post‐treatment toxicities.

           pro‐gastrin‐releasing peptide (GRP)‐derived peptides in
           renal cell carcinoma: a potential target for future therapy
    • Authors: Joseph Ischia; Oneel Patel, Kapil Sethi, Marianne S. Nordlund, Damien Bolton, Arthur Shulkes, Graham S. Baldwin
      Pages: n/a - n/a
      Abstract: Objective To determine the expression and biology of the neuroendocrine growth factor gastrin‐releasing peptide (GRP) and other proGRP‐derived peptides in renal cancer. Materials and Methods Receptor binding studies, enzyme‐linked immunosorbent assay (ELISA) and radioimmunoassay, were used to quantitate the presence of proGRP‐derived peptide receptors and their ligands in renal cancer cell lines and human renal cancers. Biological activity of proGRP peptides was confirmed with proliferation, migration, and extracellular‐signal‐regulated kinases 1 and 2 (ERK1/2) activation assays in vitro. In vivo, ACHN renal cancer xenografts were treated with proGRP‐derived peptides to assess tumour size and necrosis. hypoxia‐inducible factor 1α (HIF1α) and vascular endothelial growth factor (VEGF) expression were investigated with Western blotting and ELISA respectively, to determine the possible contribution of the proGRP peptides to tumour viability. Results In ACHN cells that expressed both proGRP‐ and GRP‐receptors, the expression of proGRP binding sites was 80‐fold greater than the GRP‐receptor (GRPR). C‐terminal proGRP‐derived peptides stimulated the activation of ERK1/2, but with a different time course to GRP, consistent with the suggestion that these peptides may have unique cellular functions. Both GRP and proGRP47–68 stimulated proliferation and migration of ACHN cells in vitro, but only GRP reduced the extent of tumour necrosis in ACHN xenografts. GRP, but not proGRP47–68, was able to induce HIF1α and VEGF expression in ACHN cells. This may account in part for the reduction in necrosis after GRP treatment. C‐terminal proGRP‐derived peptides were present in all three renal cancer cell lines and a panel of human renal cancers, but mature amidated GRP was absent. Conclusion C‐terminal proGRP peptides are more abundant in renal cancers and their cell lines than the more extensively studied amidated peptide, GRP. These results suggest that C‐terminal proGRP‐derived peptides may be a better target for novel renal cancer treatments.

      Pages: n/a - n/a
      Abstract: Objectives To evaluate the relationship between surgeon volume of radical cystectomy (RC) and postoperative morbidity, and to assess the economic burden of bladder cancer in the USA. Methods We captured all patients who underwent RC (International Classification of Diseases, ninth revision, code 57.71) between 2003 and 2010, using a nationwide hospital discharge database. Patient, hospital and surgical characteristics were evaluated. The annual volume of RCs performed by the surgeons was divided into quintiles. Multivariable regression models were developed, adjusting for clustering and survey weighting, to evaluate the outcomes, including 90‐day major complications (Clavien grade III–V) and direct patient costs. We adjusted for clustering and weighting to achieve a nationally representative analysis. Results The weighted cohort included 49 792 patients who underwent RC, with an overall 90‐day major complication rate of 16.2%. Compared with surgeons performing one RC annually, surgeons performing ≥7 RCs each year had 45% lower odds of major complications (odds ratio [OR] 0.55; P < 0.001) and lower costs by $1690 (P = 0.02). Results were consistent when we analysed surgeon volume as a continuous variable and when we examined the surgeons with the highest volumes (≥28 cases annually), which showed markedly lower odds of major complications compared with the surgeons with the lowest volumes (OR 0.45, 95% CI 0.31–0.67; P < 0.001). Compared with patients who did not have any complications, those who had a major complication were associated with significantly higher 90‐day median direct hospital costs ($43 965 vs $24 341; P < 0.001). Conclusions We showed that there was an inverse relationship between surgeon volume and the development of postoperative 90‐day major complication rates as well as direct hospital costs. Centralisation of RC to surgeons with higher volumes may reduce the development of postoperative major complications, thereby decreasing the burden of bladder cancer on the healthcare system.

      Abstract: Objective To analyse the use of Twitter at urology conferences to enhance the social media conference experience. Materials and Methods We prospectively registered the hashtags of eight international urology conferences taking place in 2013, using the social media metrics website, Symplur.com. In addition, we prospectively registered the hashtag for the European Association of Urology (EAU) Annual Congress for 3 consecutive years (2012–2014) to analyse the trend in the use of Twitter at a particular meeting. Metrics including number of ‘tweets’, number of participants, tweet traffic per day, and overall digital impressions, which were captured for 5 days before each conference, the conference itself, and the following 2 days. We also measured corresponding social media activity at a very large non‐urology meeting (the American Society of Clinical Oncology) for comparative purposes. Results Twitter activity was noted at all eight conferences in 2013. In all, 12 363 tweets were sent generating over 14 million impressions. The number of participants tweeting at each meeting varied from 80 (Congress of the Société Internationale d'Urologie, #SIU2013) to 573 (the American Urological Association, #AUA13). Overall, the AUA meeting (#AUA13) generated the most Twitter activity with >8.6 million impressions and a total of 4663 tweets over the peri‐conference period. It also had the most impressions and tweets per day over this period, at 717 000 and 389, respectively. The EAU Annual Congress 2013 (#EAU13) generated 1.74 million impressions from a total of 1762 tweets from 236 participants. For trends in Twitter use, there was a very sharp rise in Twitter activity at the EAU Annual Congress between 2012 and 2014. Over this 3‐year period, the number of participants increased almost 10‐fold, leading to an increase in the number of tweets from 347 to almost 6000. At #EAU14, digital impressions reached 7.35 million with 5903 tweets sent by 797 participants. Conclusions Urological conferences, to a varying extent, have adopted social media as a means of amplifying the conference experience to a wider audience, generating international engagement and global reach. Twitter is a very powerful tool that amplifies the content of scientific meetings, and conference organisers should put in place strategies to capitalise on this.

      Abstract: Objective To compare outcomes of patients with lymph node (LN)‐positive urothelial carcinoma of the bladder (UCB) treated with or without cisplatin‐based combined adjuvant chemotherapy (AC) after radical cystectomy (RC). Patients and Methods We retrospectively analysed 1523 patients with LN‐positive UCB, who underwent RC with bilateral pelvic LN dissection. All patients had no evidence of disease after RC. AC was administered within 3 months. Competing‐risks models were applied to compare UCB‐related mortality. Results Of the 1523 patients, 874 (57.4%) received AC. The cumulative 1‐, 2‐ and 5‐year UCB‐related mortality rates for all patients were 16%, 36% and 56%, respectively. Administration of AC was associated with an 18% relative reduction in the risk of UCB‐related death (subhazard ratio 0.82, P = 0.005). The absolute reduction in mortality was 3.5% at 5 years. The positive effect of AC was detectable in patients aged ≤70 years, in women, in pT3–4 disease, and in those with a higher LN density and lymphovascular invasion. This study is limited by its retrospective and non‐randomised design, selection bias, the absence of central pathological review and lack in standardisation of LN dissection and cisplatin‐based protocols. Conclusion AC seems to reduce UCB‐related mortality in patients with LN‐positive UCB after RC. Younger patients, women and those with high‐risk features such as pT3–4 disease, a higher LN density and lymphovascular invasion appear to benefit most. Appropriately powered prospective randomised trials are necessary to confirm these findings.

      Abstract: Objective To systematically review and evaluate the impact of the International Continence Society (ICS)‐2002 report on standardisation of terminology in nocturia, on publications reporting on nocturia and nocturnal polyuria (NP). In 2002, the ICS defined NP as a Nocturnal Polyuria Index (nocturnal urine volume/total 24‐h urine volume) of >0.2–0.33, depending on age. Materials and Methods In April 2013 the PubMed and Embase databases were searched for studies (in English, German, French or Dutch) based on original data and adult participants, investigating the relationship between nocturia and NP. A methodological quality assessment was performed, including scores on external validity, internal validity and informativeness. Quality scores of items were compared between studies published before and after the ICS‐2002 report. Results The search yielded 78 publications based on 66 studies. Quality scores of studies were generally high for internal validity (median 5, interquartile range [IQR] 4–6) but low for external validity. After publication of the ICS‐2002 report, external validity showed a significant change from 1 (IQR 1–2) to 2 (IQR 1–2.5; P = 0.019). Nocturia remained undefined in 12 studies. In all, 19 different definitions were used for NP, most often being the ICS (or similar) definition: this covered 52% (n = 11) of studies before and 66% (n = 27) after the ICS‐2002 report. Clear definitions of both nocturia and NP were identified in 67% and 76% before, and in 88% and 88% of the studies after the ICS‐2002 report, respectively. Conclusion The ICS‐2002 report on standardisation of terminology in nocturia appears to have had a beneficial impact on reporting definitions of nocturia and NP, enabling better interpretation of results and comparisons between research projects. Because the external validity of most of the 66 studies is considered a problem, the results of these studies may not be validly extrapolated to other populations. The ICS definition of NP is used most often. However, its discriminative value seems limited due to the estimated difference of 0.6 nocturnal voids between individuals with and without NP. Refinement of current definitions based on robust research is required. Based on pathophysiological reasoning, we argue that it may be more appropriate to define NP based on nocturnal urine production or nocturnal voided volumes, rather than on a diurnal urine production pattern.

      Abstract: Objective To investigate transient receptor potential vanilloid 4 (TRPV4) expression in bladder afferents and study the effect of TRPV4 and TRPV1 antagonists, alone and in combination, in bladder hyperactivity and pain induced by cystitis. Material and Methods TRPV4 expression in bladder afferents was analysed by immunohistochemistry in L6 dorsal root ganglia (DRG), labelled by fluorogold injected in the urinary bladder. TRPV4 and TRPV1 co‐expression was also investigated in L6 DRG neurones of control rats and in rats with lipopolysaccharide (LPS)‐induced cystitis. The effect of TRPV4 antagonist RN1734 and TRPV1 antagonist SB366791 on bladder hyperactivity and pain induced by cystitis was assessed by cystometry and visceral pain behaviour tests, respectively. Results TRPV4 is expressed in sensory neurones that innervate the urinary bladder. TRPV4‐positive bladder afferents represent a different population than the TRPV1‐expressing bladder afferents, as their co‐localisation was minimal in control and inflamed rats. While low doses of RN1734 and SB366791 (176.7 ng/kg and 143.9 ng/kg, respectively) had no effect on bladder activity, the co‐administration of the two totally reversed bladder hyperactivity induced by LPS. In these same doses, the antagonists partially reversed bladder pain behaviour induced by cystitis. Conclusions TRPV4 and TRPV1 are present in different bladder afferent populations. The synergistic activity of antagonists for these receptors in very low doses may offer the opportunity to treat lower urinary tract symptoms while minimising the potential side‐effects of each drug.

  • Transrectal ultrasonography (TRUS)‐guided pelvic plexus block to
           reduce pain during prostate biopsy: a randomised controlled trial
    • Authors: Tarun Jindal; Subhabrata Mukherjee, Rajan K. Sinha, Mir R. Kamal, Nabankur Ghosh, Barun Saha, Nilanjan Mitra, Pramod K. Sharma, Soumendra N. Mandal, Dilip Karmakar
      Abstract: Objective To assess the role of pelvic plexus block (PPB) in reducing pain during transrectal ultrasonography(TRUS)‐guided prostate biopsy, compared with the conventional periprostatic nerve block (PNB). Patients and Methods A prospective, double‐blind observational study was conducted with patients being randomised into three groups. Group‐1 (47 patients) received intrarectal local anaesthesia (IRLA) with 10 mL 2% lignocaine jelly along with pelvic plexus block (PPB) with 2.5 mL 2% lignocaine injection bilaterally. Group‐2 (46 patients) received IRLA with periprostatic nerve block (PNB). Group‐3 (46 patients) received only IRLA without any type of nerve block. The patients were requested to rate the level of pain from 0 to 10 on a visual analogue scale (VAS) at two time points: VAS‐1: during biopsy procedure and VAS‐2: 30 min after the procedure. Results The mean age of the patients, mean volume of the prostates and mean serum PSA values were comparable among the three groups. The mean pain score during biopsy was significantly less in the PPB group [mean (range) sore of 2.91 (2–4)] compared with the PNB group [mean (range) score of 4 (3–5)], and both these groups were superior to the no nerve block group [mean score of 5.4 (3–7)]. There was no significant difference between the mean pain scores, 30 min after the procedure among the three groups with the mean (range) scores being 2.75 (2–4), 2.83 (2–4) and 2.85 (2–4), respectively. Conclusion PPB is superior to conventional periprostatic nerve block (PNB) for pain control during TRUS‐guided biopsy and both are in turn superior to no nerve block.

      Abstract: Objective To investigate if short‐term treatment with dutasteride (8 weeks) before bipolar transurethral resection of the prostate (B‐TURP) can reduce intraoperative bleeding, as dutasteride a dual 5α‐reductase inhibitor (5‐ARI) blocks the conversion of testosterone into its active form dihydrotestosterone (DHT), and reduces prostate volume and prostate‐specific antigen (PSA) levels, while increasing urinary flow rate. Patients and Methods In all, 259 patients were enrolled and randomised to two groups: Group A, receiving placebo and Group B, receiving dutasteride (0.5 mg daily for 8 weeks). Blood samples were taken before and after B‐TURP for serum chemistry evaluation. In particular we evaluated blood parameters associated with blood loss [haemoglobin (Hb) and haematocrit (Ht)] and prostate vascularity [vascular endothelial growth factor (VEGF) immunoreactivity and microvessel density (MVD) using cluster of differentiation 34 (CD34) immunoreactivity]. Results Total testosterone, DHT, PSA level and prostate volume were evaluated and with the exception of DHT and PSA level there was no statistically significant differences between the groups. When comparing changes in Hb and Ht between Group A and Group B before and after B‐TURP, there was a statistically significant difference only in patients with large prostates of ≥50 mL (ΔHb 3.86 vs 2.05 g/dL and ΔHt 4.98 vs 2.64%, in Groups A and B, respectively). There was no significant difference in MVD and VEGF index in prostates of

  • Transient receptor potential channel modulators as pharmacological
           treatments for lower urinary tract symptoms (LUTS): myth or reality'
    • Authors: Yves Deruyver; Thomas Voets, Dirk De Ridder, Wouter Everaerts
      Abstract: Transient receptor potential (TRP) channels belong to the most intensely pursued drug targets of the last decade. These ion channels are considered promising targets for the treatment of pain, hypersensitivity disorders and lower urinary tract symptoms (LUTS). The aim of the present review is to discuss to what extent TRP channels have adhered to their promise as new pharmacological targets in the lower urinary tract (LUT) and to outline the challenges that lie ahead. TRP vanilloid 1 (TRPV1) agonists have proven their efficacy in the treatment of neurogenic detrusor overactivity (DO), albeit at the expense of prolonged adverse effects as pelvic ‘burning’ pain, sensory urgency and haematuria. TRPV1 antagonists have been very successful in preclinical studies to treat pain and DO. However, clinical trials with the first generation TRPV1 antagonists were terminated early due to hyperthermia, a serious, on‐target, side‐effect. TRP vanilloid 4 (TRPV4), TRP ankyrin 1 (TRPA1) and TRP melastatin 8 (TRPM8) have important sensory functions in the LUT. Antagonists of these channels have shown their potential in pre‐clinical studies of LUT dysfunction and are awaiting clinical validation.

  • Ureteroscopy for stone disease in the paediatric population: a systematic
           review
    • Authors: Hiro Ishii; Stephen Griffin, Bhaskar K. Somani
      Abstract: The aim of the present review was to look at the role of ureteroscopy (URS) for treatment of paediatric stone disease. We conducted a systematic review using studies identified by a literature search between January 1990 and May 2013. All English‐language articles reporting on a minimum of 50 patients aged ≤18 years treated with URS for stone disease were included. Two reviewers independently extracted the data from each study. A total of 14 studies (1718 procedures) were reported in patients with a mean (range) age of 7.8 (0.25–18.0) years. The mean (range) stone burden was 9.8 (1–30) mm and the mean (range) stone‐free rate (SFR) 87.5 (58–100)% with initial therapeutic URS. The majority of these stones were in the ureter (n = 1427, 83.4%). There were 180 (10.5%) Clavien I–III complications and 38 cases (2.2%) where there was a failure to complete the initial ureteroscopic procedure and an alternative procedure was performed. To assess the impact of age on failure rate and complications, studies were subcategorized into those that included children with either a mean age 6 years. (10 studies, 1377 procedures). A higher failure rate (4.4 vs 1.7%) and a higher complication rate (24.0 vs 7.1%) were observed in children whose mean age was

  • Clinical utility of 18F‐fluorocholine positron‐emission
           tomography/computed tomography (PET/CT) in biochemical relapse of prostate
           cancer after radical treatment: results of a multicentre study
    • Authors: Sonia Rodado‐Marina; Mónica Coronado‐Poggio, Ana María García‐Vicente, Jose Ramón García‐Garzón, Aurora Crespo Jara, Antonio Maldonado‐Suárez, Antonio Rodríguez‐Fernández
      Abstract: Objective To evaluate 18F‐fluorocholine positron‐emission tomography (PET)/computed tomography (CT) in restaging patients with a history of prostate adenocarcinoma who have biochemical relapse after early radical treatment, and to correlate the technique's disease detection rate with a set of variables and clinical and pathological parameters. Patients and Methods This was a retrospective multicentre study that included 374 patients referred for choline‐PET/CT who had biochemical relapse. In all, 233 patients who met the following inclusion criteria were analysed: diagnosis of prostate cancer; early radical treatment; biochemical relapse; main clinical and pathological variables; and clinical, pathological and imaging data needed to validate the results. Criteria used to validate the PET/CT: findings from other imaging techniques, clinical follow‐up, treatment response and histological analysis. Different statistical tests were used depending on the distribution of the data to correlate the results of the choline‐PET/CT with qualitative [T stage, N stage, early radical prostatectomy (RP) vs other treatments, hormone therapy concomitant to choline‐PET/CT] and quantitative [age, Gleason score, prostate‐specific antigen (PSA) levels at diagnosis, PSA nadir, PSA level on the day of the choline‐PET/CT (Trigger PSA) and PSA doubling time (PSADT)] variables. We analysed whether there were independent predictive factors associated with positive PET/CT results. Results Choline‐PET/CT was positive in 111 of 233 patients (detection rate 47.6%) and negative in 122 (52.4%). Disease locations: prostate or prostate bed in 26 patients (23.4%); regional and/or distant lymph nodes in 52 (46.8%); and metastatic bone disease in 33 (29.7%). Positive findings were validated by: results from other imaging techniques in 35 patients (15.0%); at least 6 months of clinical follow‐up in 136 (58.4%); treatment response in 24 (10.3%); histological analysis of lesions in 17 (7.3%); and follow‐up plus imaging results in 21 (9.0%). The statistical analysis of qualitative variables, corresponding to patients' clinical characteristics, and the positive/negative final PET/CT results revealed that only whether or not early treatment with RP was done was statistically significant (P < 0.001), with the number of positive results higher in patients who did not undergo a RP. Among the quantitative variables, Gleason score, Trigger PSA and PSADT clearly differentiated the two patient groups (positive and negative choline‐PET/CT: P = 0.010, P = 0.001 and P = 0.025, respectively).

  • Oncological outcomes of cryosurgery as primary treatment in T3 prostate
           cancer: experience of a single centre
    • Authors: Zhi Guo; Tongguo Si, Xueling Yang, Yan Xu
      Abstract: Objective To assess the oncological outcomes and determine prognostic factors for overall survival (OS), cancer‐specific survival (CSS), and biochemical progression‐free survival (BPFS) after cryosurgery for clinical stage T3 prostate cancer. Patients and Methods Between 2002 and 2007, 75 patients with clinical stage T3 prostate cancer received cryosurgery as primary treatment in our institution. No adjuvant treatment was provided until biochemical failure. After biochemical failure, hormone therapy was administered. Kaplan–Meier analysis was used to calculate the OS, CSS, and BPFS. Cox regression was used to identify factors predictive of survival. Results Clinical stage T3a (cT3a) was detected in 60% (45/75) of patients and cT3b detected in 40% (30/75). The 5‐year OS, CSS, and BPFS rates were 85.3%, 92.0%, and 48%, respectively. There was a significant difference when comparing the pT3a with the pT3b group for 5‐year OS (88.9% vs 80%, P = 0.02) and BPFS (55.6% vs 36.7%, P = 0.01), but there was no difference in CSS (93.3% vs 90%, P = 0.63). Stage, Gleason score, and nadir prostate‐specific antigen (PSA) were associated with BPFS, while Gleason score and nadir PSA were the most significant predictors for CSS. Conclusions Cryosurgery can offer good 5‐year OS, CSS, and BPFS rates for cT3 prostate cancer, and there was no difference between T3a and T3b for CSS. Gleason score and nadir PSA were the most significant predictors of survival. Further clinical trials are warranted for evaluating the role of cryosurgery for cT3 prostate cancer.

      Abstract: Objectives To evaluate the effect of previous prostate surgery performed for lower urinary tract symptoms (LUTS) on the ability to predict lymph node invasion (LNI) in patients subsequently diagnosed with prostate cancer, testing two widely used LNI predictive models. Patients and Methods From 1990 to 2012, we collected data on 4734 patients with prostate cancer treated with radical prostatectomy and extended pelvic LN dissection (ePLND). Of these, 4453 (94%) had no prior prostate surgery (‘naïve patients’), while 286 (6%) had previously undergone surgery for LUTS. Two LNI prediction models based on patients treated with ePLND were evaluated using the receiver operating characteristic‐derived area under the curve (AUC), the calibration plot method, and decision‐curve analyses. Results The rate of LNI was 12%, while the median number of LNs removed was 15 in both groups (P = 0.9). The two tested nomograms provided more accurate prediction in naïve patients than for those previously treated with prostate surgery for LUTS (AUC: 82% and 81% vs 68% and 71%, P = 0.01 and P = 0.04, respectively). In naïve patients the surgeon would have missed one LNI for every 53 and 34 avoided ePLND using the Briganti and Godoy nomograms, respectively; in patients previously treated with surgery for LUTS, a LNI would have been missed in 13 and 21 patients not undergoing ePLND. Conclusion The accuracy and the clinical net‐benefit of LNI prediction tools decrease significantly in patients with prior prostate surgery for LUTS. These models should be avoided in such patients, who should undergo routine ePLND.

      Abstract: Objective To investigate whether poor preoperative cardiopulmonary reserve and comorbid state dictate high‐risk status and can predict complications in patients undergoing radical cystectomy (RC). Patients and Methods In all, 105 consecutive patients with transitional cell carcinoma (TCC; stage T1–T3) undergoing robot‐assisted (38 patients) or open (67) RC in a single UK centre underwent preoperative cardiopulmonary exercise testing (CPET). Prospective primary outcome variables were all‐cause complications and postoperative length of stay (LOS). Binary logistic regression analysis identified potential predictive factor(s) and the predictive accuracy of CPET for all‐cause complications was examined using receiver operator characteristic (ROC) curve analysis. Correlations analysis employed Spearman's rank correlation and group comparison, the Mann–Whitney U‐test and Fisher's exact test. Any relationships were confirmed using the Mantel–Haenszel common odds ratio estimate, Kaplan–Meier analysis and the chi‐squared test. Results The anaerobic threshold (AT) was negatively (r = −206, P = 0.035), and the ventilatory equivalent for carbon dioxide (VE/VCO2) positively (r = 0.324, P = 0.001) correlated with complications and LOS. Logistic regression analysis identified low AT (50% of patients presenting for RC had significant heart failure, whereas preoperatively only very few (2%) had this diagnosis. Analysis using the Mann–Whitney test showed that a VE/VCO2 ≥33 was the most significant determinant of LOS (P = 0.004). Kaplan–Meier analysis showed that patients in this group had an additional median LOS of 4 days (P = 0.008). Finally, patients with an American Society of Anesthesiologists grade of 3 (ASA 3) and those on long‐term β‐blocker therapy were found to be at particular risk of myocardial infarction (MI) and death after RC with odds ratios of 4.0 (95% CI 1.05–15.2; P = 0.042) and 6.3 (95% CI 1.60–24.8; P = 0.008). Conclusion Patients with poor cardiopulmonary reserve and hypertension are at higher risk of postoperative complications and have increased LOS after RC. Heart failure is known to be a significant determinant of perioperative death and is significantly under diagnosed in this patient group.

      Abstract: Objectives To identify risk factors and develop a model for predicting recurrence of upper urinary tract urothelial carcinoma (UTUC) in the bladder in patients without a history of bladder cancer after radical nephroureterectomy (RNU). Patients and Methods We retrospectively reviewed 754 patients with UTUC without prior or concurrent bladder cancer or distant metastasis at 13 institutions in Japan. Univariate and multivariate Fine and Gray competing risks proportional hazards models were used to examine the cumulative incidence of bladder recurrence of UTUC. A risk stratification model and a nomogram were constructed. Two prediction models were compared using the concordance index (c‐index) focusing on predictive accuracy and decision‐curve analysis, which indicate whether a model is appropriate for decision‐making and determining subsequent patient prognosis. Results The cumulative incidence rates of bladder UTUC recurrence at 1 and 5 years were 15 and 29%, respectively; the median time to bladder UTUC recurrence was 10 months. Multivariate analysis showed that papillary tumour architecture, absence of lymphovascular invasion and higher pathological T stage were both predictive factors for bladder cancer recurrence. The predictive accuracy of the risk stratification model and the nomogram for bladder cancer recurrence were not different (c‐index: 0.60 and 0.62). According to the decision‐curve analysis, the risk stratification was an acceptable model because the net benefit of the risk stratification was equivalent to that of the nomogram. The overall cumulative incidence rates of bladder cancer 5 years after RNU were 10, 26 and 44% in the low‐, intermediate‐ and high‐risk groups, respectively. Conclusions We identified risk factors and developed a risk stratification model for UTUC recurrence in the bladder after RNU. This model could be used to provide both an individualised strategy to prevent recurrence and a risk‐stratified surveillance protocol.

  • Causes of death in men with localised prostate cancer: a nationwide,
           population‐based study
    • Authors: Mieke Van Hemelrijck; Yasin Folkvaljon, Jan Adolfsson, Olof Akre, Lars Holmberg, Hans Garmo, Pär Stattin
      Abstract: Objective To detail the distribution of causes of death for localised prostate cancer (PCa). Patients and Methods PCBase Sweden links the Swedish National Prostate Cancer Register (NPCR) with other nation‐wide population‐based healthcare registers. We selected all 57,187 men diagnosed with localised PCa between 1997‐2009 and their 114,374 age‐ and county‐matched PCa‐free control men. Mortality was calculated using competing risk regression analyses, taking into account PCa risk category, age, and Charlson comorbidity index (CCI). Results In men with low risk PCa, all‐cause mortality was lower compared to corresponding PCa‐free men: 10‐year all‐cause mortality was 18% for men diagnosed at age 70 with CCI=0 and 21% among corresponding controls. 31% of these cases died of CVD compared to 37% of their controls. For men with low‐risk PCa, 10‐year PCa‐mortality was 0.4%, 1%, and 3% when diagnosed at age 50, 60, and 70, respectively. PCa was the third most common cause of death (18%), after CVD (31%) and other cancers (30%). In contrast, PCa was the most common cause of death in men with intermediate and high‐risk localised PCa. Conclusions Men with low‐risk PCa had lower all‐cause mortality than PCa‐free men due to lower cardiovascular mortality, driven by early detection selection. However, for men with intermediate or high‐risk disease, PCa death was substantial, irrespective of CCI, and this was even more pronounced for those diagnosed at age 50 or 60.

  • Intermediate Analysis of A Phase Ii Trial Assessing Gemcitabine and
           Cisplatin in Locoregional or Metastatic Penile Squamous Cell Carcinoma
    • Authors: N. Houédé; L. Dupuy, A. Fléchon, P. Beuzeboc, G. Gravis, B. Laguerre, C. Théodore, S. Culine, T. Filleron, C. Chevreau
      Abstract: Objective Patients with squamous cell carcinoma of the penis and unresected loco‐regional lymph nodes and/or distant metastases have a poor prognostic with no standard of chemotherapy. We performed a phase II study evaluating the association of gemcitabine and cisplatin in this population. Patients and method Eligible patients had histological confirmed squamous cell carcinoma of the penis with unresected locoregional lymph nodes and/or distant metastases at initial diagnosis or at relapse, and measurable disease as defined by RECIST criteria. Patients were treated with the association of gemcitabine 1250 mg/m2 on day 1 over 30 minutes and cisplatin 50 mg/m2 on day 1 over 1 hour, every two weeks. Primary endpoint was the objective response rate; secondary endpoints were time to progression (TTP) and overall survival (OS). Results Twenty five patients were included in the first step of the study between February 2004 and January 2010 and received a median of 5 cycles. For ITT population, 2 patients (95%CI = [0.98 ;26.0]) presented an objective response. Thirteen patients had stable disease (52% 95%CI = [35.5‐76.8]). Median TTP is estimated at 5.48 months (95%CI = [2.40 ;11.73]). After a median follow up of 26.97 months (95%CI = [17.77 ; Not reached]), nine patients were still alive. OS median and 2 years OS rates are respectively estimated at 14.98 months (95%CI = [ 9.76 ;32.9]) and 39.32% (95%CI = [19.15 ; 59.03]). Eleven patients had a SAE (44%) within 24% were relied to chemotherapy. Conclusion The every two weeks administration of the combination of gemcitabine and cisplatin showed non‐significant responses in patients with unresected loco‐regional or metastatic penile squamous cell carcinoma. Despite manageable side effects, this combination cannot be recommended as a standard of care due to disappointing response rates observed in this negative study. Further regimens should be explored to improve the overall survival of these patients with poor prognosis.

      Abstract: Objective To determine the relationship between LUTS/BPH and 10‐year risk of CVD assessed by the Framingham Cardiovascular Risk score in a cohort of patients without previous episodes of stroke and/or acute myocardial infarction. Patients and Methods Between September 2010 to September 2014, 336 consecutive patients with BPH related LUTS were prospectively enrolled. The general 10‐year cardiovascular disease Framingham risk score, expressed as a percent and assessing the risk of atherosclerotic cardiovascular disease (CVD) events was calculated for each patients. Respectively, individuals with low risk had 10% or less CVD risk at 10 years, with intermediate risk 10‐20%, and with high risk 20% or more. Logistic regression analyses were carried out to identify variables for predicting Framingham risk score ≥ 10% and moderate‐severe LUTS (IPSS≥ 8) adjusted for confounding factors. Results As category of Framingham risk score increased, we observed higher IPSS (18.0 vs. 18.50 vs. 19.0; p

  • Sexually transmitted infections, benign prostatic hyperplasia and lower
           urinary tract symptom‐related outcomes: Results from the Prostate,
           Lung, Colorectal, and Ovarian Cancer Screening Trial
    • Authors: Benjamin N. Breyer; Wen‐Yi Huang, Charles S. Rabkin, John F. Alderete, Ratna Pakpahan, Tracey S. Beason, Stacey A. Kenfield, Jerome Mabie, Lawrence Ragard, Kathleen Y. Wolin, Robert L. Grubb III, Gerald L. Andriole, Siobhan Sutcliffe
      Abstract: Objectives The exact pathogenesis of benign prostatic hyperplasia (BPH) and related lower urinary tract symptoms (LUTS) remains unclear; however evidence supports a role of inflammation. One possible source of prostatic inflammation is sexually transmitted infections (STIs), which have been found to be positively related to LUTS in some mostly small case‐control studies or cross‐sectional surveys. The objective of our analysis is to examine whether a history of STIs or positive STI serology is associated with prevalent and incident BPH/LUTS‐related outcomes in the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial (PLCO). Methods Self‐reported history of STIs (gonorrhea, syphilis) was ascertained at baseline, and serological evidence of STIs (Chlamydia trachomatis, Trichomonas vaginalis, HPV‐16, HPV‐18, HSV‐2, HHV‐8, and CMV) was detected in baseline serum specimens. We used data collected on the baseline questionnaire, as well as results from the baseline PSA test and digital rectal exam (DRE), to define prevalent BPH/LUTS‐related outcomes as evidence of LUTS (self‐reported diagnosis of an enlarged prostate/BPH, BPH surgery, or nocturia (waking ≥2 times/night to urinate)) and evidence of prostate enlargement (PSA>1.4 ng/mL or prostate volume ≥30 cc) in men without prostate cancer. We created a similar definition of incident BPH using data from the follow‐up questionnaire completed 5‐13 years after enrollment (self‐reported diagnosis of an enlarged prostate/BPH or nocturia), data on finasteride use during follow‐up, and results from the follow‐up PSA tests and DREs. We used Poisson regression with robust variance estimation to calculate prevalence ratios (PRs) in our cross‐sectional analysis of self‐reported (n=32,900) and serologically‐detected STIs (n=1,143) with prevalent BPH/LUTS, and risk ratios in our prospective analysis of self‐reported STIs with incident BPH/LUTS (n=5,226). Results Generally null results were observed for a self‐reported history of STIs and positive STI serologies with prevalent and incident BPH/LUTS‐related outcomes, with the possible exception of T. vaginalis infection. This STI was positively associated with prevalent nocturia (PR 1.36, 95% confidence interval (CI): 1.18‐1.65), prevalent large prostate volume (PR 1.21 95% CI 1.02‐1.43), and any prevalent BPH/LUTS (PR 1.32 95% CI 1.09‐1.61); too few men had information on both STI serologies and incident BPH/LUTS to investigate associations between T. vaginalis infection and incident BPH/LUTS‐related outcomes. Conclusions Our findings do not support associations of several known STIs with BPH/LUTS‐related outcomes, although T. vaginalis infection may warrant further study.

      Abstract: Objective To conduct a systematic review and meta‐analysis of AUS placement following radical prostatectomy (RP) and radiotherapy (EBRT). Materials and methods A systematic database search was conducted using keywords, according to PRISMA guidelines. Published series of AUS insertion were retrieved, according to the inclusion criteria. The Newcastle‐Ottawa Score was used to ascertain the quality of evidence for each study. Surgical results from each case series were extracted. Data were analysed using CMA® statistical software. Results There were 1886 patients available for analysis of surgical revision outcomes, and 949 for persistent urinary incontinence outcomes from 15 and 11 studies respectively. The mean age (SD) was 66.9 ± 1.4 years and the number of patients per study was 126.6 ± 41.7. Average follow up was 36.7 ± 3.9 months (range, 18 – 68). Artificial urinary sphincter revision was higher in RP + EBRT versus RP alone, with a random effects risk ratio of 1.56 (95% Confidence Interval [CI] 1.02 – 2.72; p

  • Foxp3 expression serves as an early chronic inflammation marker of
           squamous cell differentiation and aggressive pathology of urothelial
           carcinomas in neurological patients
    • Authors: Véronique Phé; Morgan Rouprêt, Olivier Cussenot, Emmanuel Chartier‐Kastler, Xavier Gamé, Eva Compérat
      Abstract: Objective To establish whether the expression of Foxp3 provides specific diagnostic information about neurological patients with urothelial carcinoma of the bladder (UCB). Materials/methods UCB tissue samples from neurological patients were retrieved and compared to control samples. The expression of Foxp3 was analysed via immunohistochemistry of micro‐array tissue sections. The correlation between Foxp3 expression, histological parameters and tumour stage was assessed. Results Overall, 20 UCB tissue samples and 20 others without UCB from neurological patients, and 46 UCB tissue samples from non‐neurological patients were analysed. The distribution of pT of UCB in the neurological patients was as follows: 1 pTa low grade(5%), 3 pTa high grade(15%), 3 pT1(15%), 1 pT2(5%), 7 pT3(35%) and 5 pT4(25%). Squamous cell differentiation was observed in 9 UCB samples (45%). Foxp3 expression was detected in tumour tissues, including 1 pTa high grade, 1 pT1, 1 pT2, 5 pT3 and 5 pT4 tumours. Foxp3 was expressed in 11/13 muscle‐invasive tumours. All tumours displaying squamous cell differentiation expressed Foxp3. Foxp3 was not expressed in the pT3 tumours that displayed sarcomatoid and micropapillary properties. Among the bladder samples without UCB from neurological patients, no expression of Foxp3 was observed. Among the UCB samples from the non‐neurological patients, only 7 cases displayed squamous cell differentiation. All tumours that displayed squamous cell differentiation expressed Foxp3, including 1 pTa high grade, 4 pT3 and 2 pT4 tumours. Other tumours displaying urothelial differentiation did not express Foxp3. The expression of Foxp3 correlated to squamous cell differentiation in neurological(p=0.004) and non‐neurological UCB tissue(p

  • Post‐operative Radiation Therapy for Patients at High‐risk of
           Recurrence after Radical Prostatectomy: Does Timing Matter'
    • Authors: Charles C. Hsu; Alan T. Paciorek, Matthew R. Cooperberg, Mack Roach, I‐Chow J. Hsu, Peter R. Carroll
      Abstract: Objective To evaluate among prostatectomy patients at high‐risk of recurrence whether the timing of post‐operative radiation therapy (adjuvant, early salvage with detectable post‐prostatectomy PSA, or “late” salvage with PSA>1.0) significantly is associated with overall, prostate‐cancer specific or metastasis‐free survival, in a longitudinal cohort. Patients and Methods Of 6176 prostatectomy patients in the Cancer of the Prostate Strategic Urologic Research Endeavor(CaPSURE), 305 patients with high‐risk pathologic features(margin positivity, Gleason Score(pGS) 8‐10, or pT3‐T4) who underwent post‐operative radiation were examined, either in the adjuvant(≤6 months from surgery with undetectable PSA, N=76) or salvage setting(>6 months after surgery or pre‐radiation PSA>0.1, N=229). Early (PSA≤1.0, N=180) or late salvage radiation(PSA>1.0, N=49) was based on post‐prostatectomy, pre‐radiation PSA. Multivariable Cox regression examined associations with all‐cause mortality and prostate cancer‐specific mortality or metastases(PCSMM). Results After a median of 74 months from prostatectomy, 65 men died(with 37 events of PCSMM). Adjuvant and salvage radiation patients had comparable high‐risk features. Compared to adjuvant, salvage radiation(early or late) had an increased association with all‐cause mortality(hazard ratio[HR] 2.7, p=0.018) and with PCSM(HR 4.0, p=0.015). PCSM‐free survival differed by further stratification of timing, with 10‐year estimates of 88%, 84%, and 71% for adjuvant, early salvage, and late salvage radiation, respectively(P=0.026). For PCSM‐ and overall‐survival, compared to adjuvant RT, late salvage RT had statistically significantly increased risk, however early salvage RT did not. Conclusion This analysis suggests that patients who underwent early salvage radiation with PSA1.0 is associated with worse clinical outcomes.

  • External urethral sphincter electromyography in asymptomatic women and the
           influence of the menstrual cycle
    • Authors: C. Tawadros; K. Burnett, L.F. Derbyshire, T. Tawadros, N. W. Clarke, C.D. Betts
      Abstract: Objective To investigate by electromyography (EMG), the presence of complex repetitive discharges (CRDs) and decelerating bursts (DBs) in the striated external urethral sphincter during the menstrual cycle in female volunteers with no urinary symptoms and complete bladder emptying. Subjects and methods Healthy female volunteers aged 20‐40 years, with regular menstrual cycles and no urinary symptoms were recruited. Volunteers completed a menstruation chart, urinary symptom questionnaire, pregnancy test, urine dipstick, urinary free flow and post void ultrasound bladder scan. Exclusion criteria included current pregnancy, use of hormonal medication or contraception, body mass index greater than 35, incomplete voiding and a history of pelvic surgery. Eligible participants underwent an external urethral sphincter EMG, using a needle electrode, in the early follicular phase and the mid‐luteal phase of their menstrual cycles. Serum oestradiol and progesterone were measured at each EMG test. Results One hundred and nineteen women enquired about the research and following screening, 18 females were eligible to enter the study phase. Complete results were obtained in 15 women. Thirty EMG tests were undertaken in the 15 asymptomatic women. Sphincter EMG was positive for CRDs and DBs at one or both phases of the menstrual cycle in 8 (53%) of the female volunteers. Three had CRDs and DBs in both early follicular and midluteal phases. Five had normal EMG activity in the early follicular phase and CRDs and DBs in the midluteal phase. No woman had abnormal EMG activity in the early follicular phase and normal activity in the luteal phase. There was no relationship between EMG activity and age, parity or serum levels of oestradiol and progesterone. Conclusions CRDs and DB activity in the external striated urethral sphincter is present in a high proportion of asymptomatic young women. This abnormal EMG activity has been shown for the first time to change during the menstrual cycle in individual women. CRDs and DBs are more commonly found in the luteal phase of the menstrual cycle. The importance of CRDs and DBs in the aetiology of urinary retention in young women remains uncertain. The distribution and or quantity of abnormal EMG activity in the external urethral sphincter may be important. In a woman with urinary retention the finding of CRDs and DBs by needle EMG does not automatically establish Fowler's syndrome as the explanation for the bladder dysfunction. Urethral pressure profilometry may be helpful in establishing a diagnosis. Opiate use and psychological stress should be considered in young women with urinary retention.

    • Authors: Vishwanath Hanchanale; Lehana Yeo, Nawraj Subedi, Jonathan Smith, Tze Wah, Patricia Harnden, Selina Bhattarai, Sameer Chilka, Ian Eardley
      Abstract: Objectives Penile preserving surgery is increasingly offered to men with localised penile cancer and surgical margins of less than 10 mm appear to offer excellent oncological control. Invasion of the tunica albuginea (TA) and the urethra are important factors in determining the feasibility of such surgery. We assessed the accuracy of magnetic resonance imaging (MRI) in predicting the invasion of the tunica albuginea and the urethra during the primary staging of penile Cancer. Methods One hundred and four consecutive patients with clinical T1‐T3 penile cancer had a penile MRI as a part of local staging protocol. An artificial erection was induced by injecting alprostadil (prostaglandin E1). Four men with poor quality MRI images were excluded from the study. The preoperative MRI was compared to final histology to assess its accuracy in predicting the invasion of the tunica albuginea and urethral invasion. Results Data of one hunded patients who underwent penile MRI prior to definitive surgery for invasive penile carcinoma was available for analysis. The mean age was 65 years and number of patients with pathological stage T1, T2 and T3 were 32, 52 and 16 respectively. The sensitivity and specificity of MRI in predicting the invasion of tunica albuginea and urethra were 82.1%, 73.6% and 62.5%, 82.1% respectively. There were no MRI related complications. Conclusions This study shows that penile MRI is an accurate imaging modality in assessing the tunica albuginea invasion but is less sensitive in assessing urethral invasion. These results support the use of MRI in the local staging of penile cancer.

  • Guideline of guidelines: A Review of Urologic Trauma Guidelines
    • Authors: Darren J. Bryk; Lee C. Zhao
      Abstract: Objective To review the guidelines released in the last decade by several organizations regarding the optimal evaluation and management of genitourinary injuries (renal, ureteral, bladder, urethral and genital). Materials and Methods This is a review of the genitourinary trauma guidelines from the European Association of Urology (EAU) and the American Urological Association (AUA) and renal trauma guidelines from the Societe Internationale D'Urologie (SIU). Results Most recommendations are guided by the American Association for the Surgery of Trauma (AAST) organ injury severity system. Grade A evidence is very rare in genitourinary trauma, and most recommendations are based on Grade C evidence. The findings of the most recent urologic trauma guidelines are summarized. All guidelines recommend conservative management for low‐grade injuries. The major difference is for high‐grade renal trauma, where the SIU and EAU recommended exploratory laparotomy for Grade 5 renal injuries, while the more recent AUA guideline recommends initial conservative management in hemodynamically stable patients. Conclusion There is generally consensus among the three guidelines. Recommendations are based on observational or retrospective studies as well as clinical principles and expert opinions. Large‐scale prospective studies can improve the quality of evidence, and direct more effective evaluation and management of urologic trauma.

           A systematic review
    • Authors: Giuseppe Lombardi; Stefania Musco, Thomas M. Kessler, Vincenzo Li Marzi, Michele Lanciotti, Giulio Del Popolo
      Abstract: Objective To systematically review the management of sexual dysfunction (SD) due to central nervous system disorders. Methods The review was done according to the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) statement. Studies were identified independently by two reviewers using electronic searches of MEDLINE and OVID (from January 2004 to August 2014) and hand searches of reference lists and review articles. Results In patients with central nervous system disorders, neuro‐urological assessment is recommended for both genders before starting any treatment for SD. For men, blood sexual hormones evaluation is the main investigation performed prior to phosphodiesterase type 5 inhibitors (PDE5Is) treatment, whereas there is no consensus on routine laboratory tests for women. PDE5Is are the first‐line medical treatment for men, with the most robust data derived from patients with spinal cord lesion assessed by validated questionnaires, mainly the International Index of Erectile Function‐15. There is no effective medical treatment for SD in women. Sacral neuromodulation for lower urinary tract dysfunction may improve SD in both genders. Conclusions Although SD is a major burden for patients with central nervous system disorders, high‐evidence level studies are rare and only available for PDE5Is treating erectile dysfunction. Well‐designed prospective studies are urgently needed for both genders.

    • Authors: Mahesha Weerakoon; Nathan Papa, Nathan Lawrentschuk, Sue Evans, Jeremy Millar, Mark Frydenberg, Damien Bolton, Declan G Murphy
      Abstract: Objectives To ascertain the treatment trends and patterns of care, for men with prostate cancer (PC) on Active Surveillance (AS) in Victoria, Australia. Material and Methods De‐identified data was obtained for 6424 men from the PCR. Men included in this study were diagnosed with prostate cancer from 2008 to August 2012 with a minimum of 12‐month follow‐up. Patients were stratified using the NCCN risk grouping system and those who were not actively treated were identified. Data was acquired to describe the trends and uptake of AS according to public vs. private hospital sector, and regional vs. metropolitan regions. Results A total of 1603/ 6424 (24.9%) of men received no treatment with curative intent at 12 months follow‐ up. This cohort included patients in whom the chosen management plan was AS (980/1603, 61.1%), watchful waiting (WW‐ 341/1603, 21.3%), or no management plan (282/1603, 17.6%) was recorded. From this, 980/6424(15.3%) of patients were recorded as being on AS across all NCCN categories at 12 months after diagnosis. This includes 653/1816 (35.9%) of very low and low‐risk men, and 251/2820 (8.9%) of intermediate‐risk men. Of our patients on AS, 169/980 (17.2%) progressed onto active treatment after 12 months. This was radical prostatectomy in 116 (68.6%), with 32 (18.9%) undergoing external beam radiation therapy (EBRT), 12 (7.1%) undergoing brachytherapy (BT) and 9 (5.3%) undergoing androgen deprivation therapy (ADT). Overall, 629/979 (64.2%) of AS patients were notified from a private hospital, with 350/979 (35.7%) of patients notified from a public hospital (1 patient unclassified). Of these, 202/652 (30.9%) of AS patients with very low/ low risk were managed in the public sector, vs. 450/652 (69%) of very low/ low risk AS patients being managed in the private sector. In our cohort, patients with very low and low risk disease, managed in a private hospital, were more likely to be on AS (p=0.005). AS patients in the private sector were also observed to have a median age 2.8 years younger (65.6 vs. 68.4, p

    • Authors: Anna T Gavin; Frances J Drummond, Conan Donnelly, Eamonn O'Leary, Linda Sharp, Heather R Kinnear
      Abstract: Objective To document prostate cancer patient reported ‘ever experienced’ and ‘current’ prevalence of disease specific physical symptoms stratified by primary treatment received. Patients 3,348 prostate cancer survivors 2‐15 years post diagnosis. Methods Cross‐sectional, postal survey of 6,559 survivors diagnosed 2‐15 years ago with primary, invasive PCa (ICD10‐C61) identified via national, population based cancer registries in Northern Ireland and Republic of Ireland. Questions included symptoms at diagnosis, primary treatments and physical symptoms (impotence/urinary incontinence/bowel problems/breast changes/loss of libido/hot flashes/fatigue) experienced ‘ever’ and at questionnaire completion (“current”). Symptom proportions were weighted by age, country and time since diagnosis. Bonferroni corrections were applied for multiple comparisons. Results Adjusted response rate 54%; 75% reported at least one ‘current’ physical symptom (‘ever’:90%), with 29% reporting at least three. Prevalence varied by treatment; overall 57% reported current impotence; this was highest following radical prostatectomy (RP)76% followed by external beam radiotherapy with concurrent hormone therapy (HT); 64%. Urinary incontinence (overall ‘current’ 16%) was highest following RP (‘current'28%, ‘ever'70%). While 42% of brachytherapy patients reported no ‘current’ symptoms; 43% reported ‘current’ impotence and 8% ‘current’ incontinence. ‘Current’ hot flashes (41%), breast changes (18%) and fatigue (28%) were reported more often by patients on HT. Conclusion Symptoms following prostate cancer are common, often multiple, persist long‐term and vary by treatment. They represent a significant health burden. An estimated 1.6% of men over 45 is a prostate cancer survivor currently experiencing an adverse physical symptom. Recognition and treatment of physical symptoms should be prioritised in patient follow‐up. This information should facilitate men and clinicians when deciding about treatment as differences in survival between radical treatments is minimal.

    • Authors: Marc P. Schneider; Francis M. Hughes, Anne K. Engmann, J. Todd Purves, Hansjörg Kasper, Marco Tedaldi, Laura S. Spruill, Miriam Gullo, Martin E. Schwab, Thomas M. Kessler
      Abstract: Objectives To develop a urodynamic model incorporating external urethral sphincter (EUS) electromyography (EMG) in awake rats. Materials and methods Bladder catheters and EUS EMG electrodes were implanted in female Sprague Dawley rats. Assessments were performed in awake, lightly restrained animals on postoperative day 12‐14. Measurements were repeated in the same animal on day 16 under urethane anesthesia. Urodynamics and EUS EMG were performed simultaneously. In addition, serum creatinine and bladder histology was assessed. Results No significant differences in urodynamic parameters were found between bladder catheter only versus bladder catheter and EUS EMG electrode groups. Urethane anesthesia evoked prominent changes in both urodynamic parameters and EUS EMG. Serum creatinine was within the normal limits in all animals. Bladder weight and bladder wall thickness were significantly increased in both the bladder catheter only and the bladder catheter and EUS EMG group compared to controls. Conclusions Our novel urodynamic model allows repetitive measurements of both bladder and EUS function at different time points in the same animal under fully awake conditions and opens promising avenues to investigate LUTD in a translational approach.

  • Central obesity is predictive of persistent storage LUTS after surgery for
           Benign Prostatic Enlargement: results of a multicenter prospective study
    • Authors: M Gacci; A Sebastianelli, M Salvi, C De Nunzio, A Tubaro, L Vignozzi, G Corona, KT McVary, SA Kaplan, M Maggi, M Carini, S Serni
      Abstract: Objective Central obesity can be associated with the development of benign prostatic enlargement (BPE) and with the worsening of lower urinary tract symptoms (LUTS). The aim of our study was to evaluate the impact of components of Metabolic Syndrome (MetS) on urinary outcomes after surgical therapy for severe LUTS due to BPE. Materials and Methods A multicenter prospective study was conducted including 378 consecutive men surgically treated for large BPE with simple open prostatectomy (OP) or transurethral resection of the prostate (TURP), between January 2012 and October 2013. LUTS were measured by the International Prostate Symptom Score (IPSS), immediately before surgery and 6 to 12 months postoperatively. MetS was defined according the US National Cholesterol Education Program‐Adult Treatment Panel III. Results The improvement of total and storage IPSS postoperatively was related to diastolic blood pressure and waist circumference (WC). WC>102 cm was associated with a higher risk of an incomplete recovery of both total IPSS (OR: 0.343, p=0.001) and storage IPSS (OR: 0.208, p

  • Knowledge, Attitudes and Beliefs towards Management of Men with Locally
           Advanced Prostate Cancer following Radical Prostatectomy: An Australian
           Survey of Urologists
    • Authors: Bernadette (Bea) Brown; Jane Young, Andrew B Kneebone, Andrew J Brooks, Amanda Dominello, Mary Haines
      Abstract: Objective To investigate Australian urologists’ knowledge, attitudes and beliefs, and the association of these with treatment preferences relating to guideline‐recommended adjuvant radiotherapy for men with adverse pathologic features following radical prostatectomy. Subjects and methods A nationwide mailed and web‐based survey of Australian urologist members of the Urological Society of Australia and New Zealand (USANZ). Results 157 surveys were included in the analysis (45% response rate). Just over half of respondents (57%) were aware of national clinical practice guidelines for the management of prostate cancer. Urologists’ attitudes and beliefs towards the specific recommendation for post‐operative adjuvant radiotherapy for men with locally advanced prostate cancer were mixed. Just over half agreed the recommendation is based on a valid interpretation of the underpinning evidence (54.1%, 95% CI [46%, 62.2%]) but less than one third agreed adjuvant radiotherapy will lead to improved patient outcomes (30.2%, 95% CI [22.8%, 37.6%]). Treatment preferences were varied, demonstrating clinical equipoise. A positive attitude towards the clinical practice recommendation was significantly associated with treatment preference for adjuvant radiotherapy (rho = .520, p

      Abstract: Objective To investigate whether a fixed‐dose combination of 0.5 mg dutasteride and 0.4 mg tamsulosin (FDC) is more effective than watchful waiting with protocol‐defined initiation of tamsulosin therapy if symptoms did not improve (WW‐All) in treatment‐naïve men with moderately symptomatic benign prostatic hyperplasia (BPH) at risk of progression. Patients and methods This was a multicentre, randomised, open‐label, parallel‐group study (NCT01294592) in 742 men with an International Prostate Symptom Score (IPSS) of 8–19, prostate volume ≥30 cc and total serum PSA ≥1.5 ng/ml. Patients were randomised to FDC (n = 369) or WW‐All (n = 373) and followed for 24 months. All patients were given lifestyle advice. The primary endpoint was symptomatic improvement from baseline to 24 months, measured by IPSS. Secondary outcomes included BPH clinical progression, impact on quality of life (QoL), and safety. Results The change in IPSS at 24 months was significantly greater for FDC than WW‐All (–5.4 vs. –3.6 points, P < 0.001). With FDC, the risk of BPH progression was reduced by 43.1% (P < 0.001); 29% and 18% of men in the WW‐All and FDC groups had clinical progression, respectively, comprising symptomatic progression in most patients. Improvements in QoL (BPH Impact Index and question 8 of the IPSS) were observed in both groups but were significantly greater with FDC (P < 0.001). The safety profile of FDC was consistent with established profiles of dutasteride and tamsulosin. Conclusion FDC therapy with dutasteride and tamsulosin, plus lifestyle advice, caused rapid and sustained improvements in men with moderate BPH symptoms at risk of progression with significantly greater symptom and QoL improvements and a significantly reduced risk of BPH progression compared with WW plus initiation of tamsulosin as per protocol.

    • Authors: Matthew DF McInnes; D. Robert Siemens, William J. Mackillop, Yingwei Peng, Shelly Wei, Nicola Schieda, Christopher M. Booth
      Abstract: Objective To test the hypotheses that: a) use of pre‐operative imaging for muscle‐invasive bladder cancer (MIBC) conforms to practice guidelines; b) pre‐operative imaging, through more accurate staging is associated with improved outcomes. Materials & Methods In this population‐based cohort study, records of treatment were linked to the Ontario Cancer Registry to identify all patients with MIBC treated with cystectomy from 1994‐2008. Utilization of chest, abdomen‐pelvis and bone imaging were evaluated. Trends were evaluated over time. Logistic regression was used to analyze factors associated with utilization. Cox model analyses were used to explore associations between imaging and survival. Results 2802 patients with MIBC underwent cystectomy during 1994‐2008. Over the three 5‐year study periods, an increase in the proportion of patients having pre‐operative: chest x‐ray(CXR)(55%,64%,63%,p

    • Authors: Wee Loon Ong; Mahesha Weerakoon, Sean Huang, Eldho Paul, Nathan Lawrentschuk, Mark Frydenberg, Daniel Moon, Declan Murphy, Jeremy Grummet
      Abstract: Objectives To present the Victorian Transperineal Biopsy Collaboration (VTBC) experience in patients with no prior prostate cancer diagnosis, assessing the cancer detection rate, pathological outcomes and anatomical distribution of cancer within the prostate Patients and Methods VTBC was established through partnership between urologists performing transperineal biopsies of the prostate (TPB) at three institutions in Melbourne. Consecutive patients who had TPB, as first biopsy or repeat biopsy following previous negative TRUS biopsy, between September 2009 and September 2013 in the VTBC database were included in this study. Data for each patient was collected prospectively (except for TPB prior to 2011 in one institution), based on the minimum dataset published by the Ginsburg Study Group Univariate and multivariate analyses were performed to identify factors predictive of cancer detection on TPB Results 160 patients were included in the study, of these 57 patients had TPB as first biopsy while 103 had TPB as repeat biopsy after previous negative TRUS biopsies The median patient age at TPB was 63, with the repeat biopsy patients having higher median serum PSA level (5.8ng/ml for first biopsy, and 9.6ng/ml for repeat biopsy) and larger prostate volumes (40cc for first biopsy, and 51cc for repeat biopsy) Cancer was detected in 53% of first biopsy patients and 36% of repeat biopsy patients, of which 87% and 81%, respectively, were clinically significant cancers, defined as Gleason score of 7 or higher, or more than 3 positive cores of Gleason 6 75% of cancers detected in repeat biopsies involved the anterior region (based on the Ginsburg Study Group's recommended biopsy map), while 25% were confined exclusively within the anterior region; a lower proportion of only 5% of cancer detected in first biopsies were confined exclusively within the anterior region Age, serum PSA level and prostate volume were predictive of cancer detection in repeat biopsies, while only age was predictive of cancer detection in first biopsies Conclusions TPB is an alternative approach to TRUS biopsy of the prostate, offering a high rate of detection of clinically significant cancer TPB provides excellent sampling of the anterior region of the prostate, which is often under‐sampled using the TRUS approach, and should be considered an option for all men in whom a prostate biopsy is indicated.

      Pages: n/a - n/a
      Abstract: Objective To evaluate whether pathological factors are associated with differential effect of adjuvant chemotherapy (ACT). Patients and Methods In this population‐based retrospective cohort study, we linked electronic records of treatment and surgical pathology to the Ontario Cancer Registry. The study population included all patients with muscle‐invasive bladder cancer undergoing cystectomy in Ontario 1994–2008. Factors associated with overall (OS) and cancer‐specific survival (CSS) were evaluated using Cox proportional hazards. We tested for interaction between the following variables and ACT effect‐size: N‐stage, margin status, T‐stage, and lymphovascular invasion (LVI). Results The study population included 2802 patients; 19% were treated with ACT. Interaction terms with ACT for OS/CSS are: N‐stage (both P < 0.001); margin status (P = 0.054/P = 0.048); T‐stage (P = 0.509/P = 0.286); and LVI (P = 0.361/P = 0.405). Magnitude of effect for ACT was greater for patients with node‐positive disease [OS: hazard ratio (HR) 0.56, 95% confidence interval (CI) 0.47–0.67; CSS: HR 0.60, 95% CI 0.49–0.72] than for patients with node‐negative disease (OS: HR 0.80, 95% CI 0.61–1.03; CSS: HR 0.79, 95% CI 0.59–1.07). ACT was also associated with greater effect among patients with involved margins (OS: HR 0.45, 95% CI 0.33–0.62; CSS: HR 0.40, 95% CI 0.28–0.57) compared with patients with negative margins (OS: HR 0.75, 95% CI 0.65–0.87; CSS: HR 0.79, 95% CI 0.67–0.93). Conclusions In this population‐based cohort study we observe evidence of interaction between ACT effect and nodal stage and surgical margin status. Our results suggest that patients at highest risk of disease recurrence may derive greatest benefit from ACT.

      Pages: n/a - n/a
      Abstract: Objective To evaluate the benefit of docetaxel rechallenge in patients with metastatic castration‐resistant prostate cancer (mCRPC) relapsing after an initial good response to first‐line docetaxel. Patients and Methods We retrospectively reviewed the records of consecutive patients with mCRPC with a good response to first‐line docetaxel [serum prostate specific antigen (PSA) decrease ≥50%; no clinical/radiological progression]. We analysed the impact of management at relapse (docetaxel rechallenge or non‐taxane‐based therapy) on PSA response, symptomatic response (performance status/pain/analgesic consumption), and overall survival (OS). We used multivariate stepwise logistic regression to analyse potential predictors of a favourable outcome. Results We identified 270 good responders to first‐line docetaxel. The median progression‐free interval (PFI) was 6 months from the last docetaxel dose. At relapse, 223 patients were rechallenged with docetaxel (82.5%) and 47 received non‐taxane‐based therapy. There was no significant difference in median OS {18.2 [95% confidence interval (CI) 16.1–22.00] and 16.8 [95%CI 13.4–21.5] months, respectively, P = 0.35}. However, good PSA response and symptom relief/stable disease were more frequent on docetaxel rechallenge (40.4% vs 10.6%, P < 0.001 for PSA). A PFI of >6 months and added estramustine predicted a good PSA response and symptomatic response on docetaxel rechallenge but only a PFI of >6 months predicted longer OS. Haemoglobin (6 months, but did not prolong survival. Potential benefits should be weighed against the risk of cumulative toxicity.

  • Non‐steroidal antiandrogen monotherapy compared with luteinising
           hormone–releasing hormone agonists or surgical castration
           monotherapy for advanced prostate cancer: a Cochrane systematic review
    • Authors: Frank Kunath; Henrik R. Grobe, Gerta Rücker, Edith Motschall, Gerd Antes, Philipp Dahm, Bernd Wullich, Joerg J. Meerpohl
      Abstract: Objective ● To assess the effects of non‐steroidal antiandrogen monotherapy compared with luteinising hormone–releasing hormone agonists or surgical castration monotherapy for treating advanced hormone‐sensitive stages of prostate cancer. Materials and Methods ● We searched the Cochrane Prostatic Diseases and Urologic Cancers Group Specialized Register (PROSTATE), the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, Web of Science with Conference Proceedings, three trial registries and abstracts from three major conferences to 23 December 2013, together with reference lists, and contacted selected experts in the field and manufacturers. ● We included randomised controlled trials comparing non‐steroidal antiandrogen monotherapy with medical or surgical castration monotherapy for men in advanced hormone‐sensitive stages of prostate cancer. ● Two review authors independently examined full‐text reports, identified relevant studies, assessed the eligibility of studies for inclusion, extracted data and assessed risk of bias as well as quality of evidence according to GRADE. ● We used Review Manager 5.2 for data synthesis and used the fixed‐effect model as primary analysis (when heterogeneity low with I2 less than 50%); we used a random‐effects model when confronted with substantial or considerable heterogeneity (I2 ≥ 50%). Results ● Eleven studies involving 3060 randomly assigned participants were included in this review. Use of non‐steroidal antiandrogens decreased overall survival (hazard ratio (HR) 1.24, 95% confidence interval (CI) 1.05 to 1.48, six studies, 2712 participants) and increased clinical progression (one year: risk ratio (RR) 1.25, 95% CI 1.08 to 1.45, five studies, 2067 participants; 70 weeks: RR 1.26, 95% CI 1.08 to 1.45, six studies, 2373 participants; two years: RR 1.14, 95% CI 1.04 to 1.25, three studies, 1336 participants), as well as treatment failure (one year: RR 1.19, 95% CI 1.02 to 1.38, four studies, 1539 participants; 70 weeks: RR 1.27, 95% CI 1.05 to 1.52, five studies, 1845 participants; two years: RR 1.14, 95% CI 1.05 to 1.24, two studies, 808 participants), compared with medical or surgical castration. ● The quality of evidence for overall survival, clinical progression and treatment failure was rated as moderate according to GRADE. ● Use of non‐steroidal antiandrogens increased the risk for treatment discontinuation due to adverse events (RR 1.82, 95% CI 1.13 to 2.94, eight studies, 1559 participants), including events such as breast pain (RR 22.97, 95% CI 14.79 to 35.67, eight studies, 2670 participants) and gynaecomastia (RR 8.43, 95% CI 3.19 to 22.28, nine studies, 2774 participants) The risk of other adverse events, such as hot flashes (RR 0.23, 95% CI 0.19 to 0.27, nine studies, 2774 participants) was decreased when non‐steroidal antiandrogens were used. The quality of evidence for breast pain, gynaecomastia and hot flashes was rated as moderate according to GRADE. ● The effects of non‐steroidal antiandrogens on cancer‐specific survival and biochemical progression remained unclear. Conclusions ● Non‐steroidal antiandrogen monotherapy compared to medical or surgical castration monotherapy for advanced prostate cancer is less effective in terms of overall survival, clinical progression, treatment failure and treatment discontinuation due to adverse events. ● Evidence quality was rated as moderate according to GRADE; therefore further research is likely to have an important impact on results for patients with advanced but non‐metastatic prostate cancer treated with non‐steroidal antiandrogen monotherapy.

      Abstract: Objective ● To evaluate the patient experience of our dedicated botulinum toxin A (BTX‐A) service using a validated patient‐reported experience measure (PREM) and asses patient‐reported satisfaction with treatment. Materials and methods ● The first 100 patients who underwent BTX‐A treatment for refractory idiopathic detrusor overactivity (IDO) in our institution were contacted for telephone interview. They had all been assessed, injected and followed up in a dedicated BTX‐A clinic. ● Patients were asked to complete a validated PREM‐ the Client Satisfaction Questionnaire (CSQ‐8)‐ as well as a questionnaire developed in our department to assess satisfaction with the results of the treatment. ● The majority of patients received 200 U OnabotulinumtoxinA (Botox®) via an outpatient local anesthetic flexible cystoscopy technique. Results ● Complete data was available for 72 patients. Forty‐nine patients were continuing to receive BTX‐A treatment whilst 23 had opted for no further injections. ● The overall mean CSQ‐8 satisfaction score was 38.3 (SD 3.3) indicating a high level of patient satisfaction with the service offered in our institution. There was a significant difference in total satisfaction scores between those still receiving BTX‐A (mean score 29.8) and those who have discontinued treatment (mean score 25.1) (p

           experience
    • Authors: Zhipeng Mai; Weigang Yan, Yi Zhou, Zhien Zhou, Jian Chen, Yu Xiao, Zhiyong Liang, Zhigang Ji, Hanzhong Li
      Abstract: Objective • To assess the efficacy and safety of transperineal template‐guided prostate biopsy. Materials and Methods • From December 2003 to December 2013, a total of 3007 patients (30‐91 years old, mean age 69.1) who met the inclusion criteria underwent 11‐region transrectal ultrasound‐guided transperineal template prostate biopsy. • The inclusion criteria included a prostate‐specific antigen (PSA) level of 4.0 ng/ml or greater and abnormal prostate gland findings on digital rectal examination, ultrasound, CT or MRI. The median PSA level was 11.0 ng/ml (range 0.2‐100 ng/ml). • The prostate cancer detection rate and prostate biopsy adverse effects, as well as prostate cancer spatial distribution were analyzed. Results • A mean of 19.3 cores (range 11 to 44) were obtained for each biopsy, and more cores were obtained in larger prostates than in smaller ones. • One to four cores were collected from each region. Prostate cancer was detected in 1067 of the 3007 patients (35.5%). The prostate cancer detection rates in groups with PSA levels of 0‐4.0 ng/ml, 4.1‐10.0 ng/ml, 10.1‐20.0 ng/ml, 20.1‐50.0 ng/ml, and 50.1‐100.0 ng/ml were 15.3% (27/176), 21.0% (248/1179), 32.6% (318/975), 56.0% (232/414), and 92.0% (241/262), respectively. • The mean positives for cancer in regions 1‐10 and region 11 (the apical region) were 46.7% vs. 52.0% (P=0.014). • Regarding adverse effects, 47.0% of the patients reported hematuria, 6.1% developed hemospermia, 1.9% required short‐term catheterization after biopsy because of acute urinary retention, and 0.03% (one patient) developed urosepsis. Conclusions • Transrectal ultrasound‐guided transperineal template prostate biopsy is safe and accurate. • The current study suggests that prostate carcinoma foci are more frequently localized in the apical region.

  • Comparison of systematic transrectal biopsy to transperineal
           MRI/ultrasound‐fusion biopsy for the diagnosis of prostate cancer
    • Authors: Angelika Borkowetz; Ivan Platzek, Marieta Toma, Michael Laniado, Gustavo Baretton, Michael Froehner, Rainer Koch, Manfred Wirth, Stefan Zastrow
      Abstract: Objectives • To compare targeted, transperineal MRI/ultrasound‐fusion biopsy to systematic transrectal biopsy in patients with previous negative or first prostate biopsy. • To evaluate the gain in diagnostic information with systematic biopsies in addition to targeted MRI/ultrasound‐fusion biopsies. Patients and methods • 263 consecutive patients with suspicion of prostate cancer (PCa) were investigated. • All patients were evaluated by 3 Tesla multiparametric magnetic resonance imaging (mpMRI) applying the European Society of Urogenital Radiology (ESUR) criteria. • All patients underwent MRI/ultrasound‐fusion biopsy transperineally (mean nine cores) and additionally a systematic transrectal biopsy (mean 12 cores). Results • 195 patients underwent repeat biopsy and 68 patients underwent first biopsy. • Median age was 66yrs, median PSA‐level was 8.3ng/mL, median prostate volume was 50mL. Overall, PCa detection rate was 52% (137/263). • MRI/ultrasound‐fusion biopsy detected significantly more PCa than systematic prostate biopsy (44% (116/263) vs. 35% (91/263); p=0.0023). In repeat biopsy, the detection rate was 44% (85/195) in targeted and 32% (62/195) in systematic biopsy (p=0.0023). In first biopsy, the detection rate was 46% (31/68) in targeted and 43% (29/68) in systematic biopsy (p=0.5271). • 80% (110/137) of biopsy‐proven PCa were clinically significant. • Regarding the upgrading of Gleason Score (GS), 44% (32/72) more clinically significant PCa was detected by using additional targeted biopsy compared to systematic biopsy alone. Conversely, 12% (10/94) more clinically significant cancer was found by systematic biopsy additionally to targeted biopsy. Conclusions • MRI/ultrasound‐fusion biopsy was associated with a higher detection rate of clinically significant PCa while taking fewer cores both, especially in patients with prior negative biopsy. • Due to a high portion of additional tumours with GS ≥ 7 detected in addition to targeted biopsy, systematic biopsy should still be performed additionally to targeted biopsy.

  • The treatment of penile carcinoma in situ (CIS) within a UK
           supra‐regional network
    • Authors: Marc Lucky; Kusuma V.R. Murthy, Beverley Rogers, Stephen Jones, Maurice W. Lau, Vijay K. Sangar, Nigel J. Parr
      Abstract: Objectives To review outcomes of the treatment of carcinoma in situ (CIS) of the penis at a large supra‐regional penile cancer network, where centralisation has permitted greater experience with treatment outcomes, and suggest treatment strategies. Patients and Methods The network penile cancer database, which details presentation, treatment and complications was analysed from 2003 to 2010, identifying patients with CIS, with a minimum follow‐up of 2 years, looking at treatments administered and outcomes. Results In all, 57 patients with mean (range) age of 61 (34–91) years were identified. In all, 18 were treated by circumcision only, 20 by circumcision and local excision (LE) and 19 by circumcision and 5‐flurouracil (5‐FU). The mean (range) follow‐up was 3.5 (2–8) years. Of those treated by circumcision none subsequently developed CIS on the glans. For those who underwent circumcision + LE, five of 20 (25%) developed recurrence requiring further treatment. Of those treated by circumcision + 5‐FU, 14/19 (73.7%) completely responded. Of the five incomplete responders, two had focal invasive malignancy at repeat biopsy. One incomplete responder underwent glansectomy and four grafting. No complete responders relapsed. Complications of 5‐FU included significant inflammatory response in seven (36.8%), with two requiring hospital admission and one neo‐phimosis (5.3%). Conclusion This study suggests that patients undergoing circumcision for isolated CIS and complete responders to 5‐FU may require only short‐term follow‐up, as recurrence is unlikely, whereas longer follow up is required for all other patients. However, numbers in this study are small and larger studies are needed to support this. An incomplete response to 5‐FU dictates immediate re‐biopsy, as it carries a significant chance of previously undetected invasive disease.

  • Modified transurethral resection of the prostate (TURP) for men with
           moderate lower urinary tract symptoms (LUTS) before brachytherapy is safe
           and feasible
    • Authors: Philip Brousil; Muddassar Hussain, Mark Lynch, Robert W. Laing, Stephen E.M. Langley
      Abstract: Objective To report the urinary toxicity outcomes for patients at greater risk of voiding symptoms and retention who received a modified limited transurethral resection of the prostate (TURP) before low‐dose rate (LDR) brachytherapy. Patients and Method Data were analysed from patients receiving the above procedures between 2006 to present, taken from the prospective brachytherapy database of 2000 patients at the St. Luke's Cancer Centre. The limited TURP (TURPBXT) was performed at a median (range) of 64 (25–205) days before seed implantation with a median resection weight of 1.15 g. Selection criteria were based on patients with moderate lower urinary tract symptoms, poor flow or post‐void residual urine volume (PVR), or a prominent middle lobe or high bladder neck on transrectal ultrasonography. Baseline prostate cancer characteristics, uroflowmetry, International Prostate Symptom Score (IPSS) and quality‐of‐life QoL scores were collected and compared with follow‐up IPSS and QoL scores. Results Data for 112 patients was gathered from the database. The TURPBXT resulted in statistically significant improvements before LDR brachytherapy in maximum urinary flow rate (Qmax) and PVR, IPSS and QoL scores (the mean Qmax before vs after the TURPBXT was 11.3 vs 16.7 mL/s). The IPSS and QoL scores at 6 months after seed implantation were increased compared with baseline values before the TURPBXT (mean IPSS at 6 months 11.7 vs 9.2 before TURPBXT), but no difference at 1 year (mean IPSS 9), and improved scores at 2, 3, 4 and 5 years follow‐up (mean IPSS of 7.9, 5.6, 5.3 and 7.4, respectively). Conclusion The present study suggests patients at increased risk of deteriorating voiding symptoms, including urinary retention, are no longer contraindicated against LDR brachytherapy if they receive a modified TURP before seed implantation. This procedure does not appear to carry the risk of urinary incontinence thought to be associated with a conventional TURP before LDR brachytherapy.

  • Extraprostatic extension (EPE) of prostatic carcinoma: is its proximity to

    • Authors: Ruta Gupta; Rachel O'Connell, Anne‐Maree Haynes, Phillip D. Stricker, Wade Barrett, Jennifer J. Turner, Warick Delprado, Lisa G. Horvath, James G. Kench
      Abstract: Objective To examine the association between histopathological factors of extraprostatic prostate cancer and outcome. Patients and Methods Patients with extraprostatic extension (EPE) without positive margins, seminal vesicle or lymph node involvement were analysed from a consecutive radical prostatectomy cohort of 1136 (2002–2006) for: (i) distance of EPE from the margin; (ii) Gleason score of the EPE; and (iii) extent of EPE. Log‐rank, Kaplan–Meier, and Cox regression analyses were performed. Results The study included 194 pT3a, pN0, R0 patients with a median follow‐up of 5.4 years, with 37 (19%) patients experiencing biochemical relapse (BCR). On univariable analysis, patients with a Gleason score of ≥8 in the extraprostatic portion showed increased incidence of BCR compared with those with Gleason scores of ≤7 (P = 0.03). The proximity of the EPE to the margin (0.01–7.5 mm) did not correlate with BCR. On multivariable analysis, the extent of EPE, the Gleason score of the dominant nodule or of the EPE portion did not correlate with BCR. Conclusion Data from this study using current International Society of Urological Pathology Gleason scoring and EPE criteria indicate that close proximity of EPE to the margin is not associated with recurrence. Gleason score ≥8 within EPE is associated with an increased BCR risk on univariable analysis, but larger studies are required to confirm whether extensive Gleason pattern 4 in an EPE indicates increased risk in an otherwise overall Gleason score 7 cancer.

      Abstract: Objective To compare cancer detection rates and concordance between magnetic resonance imaging and ultrasound (MRI‐US) fusion‐guided prostate biopsy cores obtained from axial and sagittal approaches. Patients and Methods Institutional records of MRI‐US fusion‐guided biopsy were reviewed. Detection rates for all cancers, Gleason ≥3 + 4 cancers, and Gleason ≥4 + 3 cancers were computed. Agreement between axial and sagittal cores for cancer detection, and frequency where one was upgraded the other was computed on a per‐target and per‐patient basis. Results In all, 893 encounters from 791 patients that underwent MRI‐US fusion‐guided biopsy in 2007–2013 were reviewed, yielding 4688 biopsy cores from 2344 targets for analysis. The mean age and PSA level at each encounter was 61.8 years and 9.7 ng/mL (median 6.45 ng/mL). Detection rates for all cancers, ≥3 + 4 cancers, and ≥4 + 3 cancers were 25.9%, 17.2%, and 8.1% for axial cores, and 26.1%, 17.6%, and 8.6% for sagittal cores. Per‐target agreement was 88.6%, 93.0%, and 96.5%, respectively. On a per‐target basis, the rates at which one core upgraded or detected a cancer missed on the other were 8.3% and 8.6% for axial and sagittal cores, respectively. Even with the inclusion of systematic biopsies, omission of axial or sagittal cores would have resulted in missed detection or under‐characterisation of cancer in 4.7% or 5.2% of patients, respectively. Conclusion Cancer detection rates, Gleason scores, and core involvement from axial and sagittal cores are similar, but significant cancer may be missed if only one core is obtained for each target. Discordance between axial and sagittal cores is greatest in intermediate‐risk scenarios, where obtaining multiple cores may improve tissue characterisation.

      Abstract: Objective To assess the sensitivity and specificity of blue‐light cystoscopy (BLC) with hexaminolevulinate as an adjunct to white‐light cystoscopy (WLC) versus WLC alone for the detection of non‐muscle‐invasive bladder cancer (NMIBC), in routine clinical practice in Spain. Material and Methods An intra‐patient comparative, multicentre, prospective, observational study. Adult patients with suspected or documented primary or recurrent NMIBC at eight Spanish centres were included in the study. All patients were examined with WLC followed by BLC with hexaminolevulinate. We evaluated the detection rate of bladder cancer lesions by WLC and BLC with hexaminolevulinate, overall and by tumour stage and compared with histological examination of the biopsied lesions. Sensitivity and specificity was calculated. Results 1,569 lesions were identified from 283 patients: 621 were tumour lesions according to histology and 948 were false‐positives. Of the 621 tumour lesions, 475 were detected by WLC (sensitivity 76.5%; 95% CI 73.2–79.8) and 579 were detected by BLC (sensitivity 93.2%; 95% CI 91.0–95.1; p

      Abstract: Objective •  To compare performance of three continence management devices and absorbent pads used by men with persistent urinary incontinence (> 1yr) post treatment for prostate cancer. •  Patients and Methods •  Randomised, controlled trial of 56 men with one year follow up. •  Three devices were tested for three weeks each: sheath drainage system, body‐worn urinal, penile clamp. Device and pad performance were assessed. •  Quality of life (QOL) was measured at baseline and follow‐up with the King's Health Questionnaire. •  Stated (intended use) and revealed (actual use) preference for products was assessed •  Value‐for‐money was gathered. Results Substantial and significant differences in performance were found: •  Sheath: good for extended use (e.g. golf and travel) when pad changing is difficult. Good for keeping skin dry, not leaking, not smelling and convenient for storage and travel; •  Body‐worn urinal: generally rated worse than the sheath and was mainly used for similar activities but by men who could not use a sheath (e.g. retracted penis); not good for seated activities. •  Clamp: good for short vigorous activities like swimming/exercise. Most secure, least likely to leak, most discreet but almost all men described it as uncomfortable or painful. •  Pads: good for everyday activities and best for night‐time use. Most easy to use, comfortable when dry but most likely to leak and most uncomfortable when wet. •  A preference for having a mixture of products to meet daytime needs; around two thirds of men were using a combination of pads and devices after testing compared to baseline. Conclusions •  This is the first trial to systematically compare different continence management devices for men •  Pads and devices have different strengths which make them particularly suited to certain circumstances and activities. •  Most men prefer to use pads at night but would choose a mixture of pads and devices during the day. •  Device limitations were important but may be overcome by better design.

      Abstract: Objective Biochemical recurrence (BCR) is a widely used surrogate for disease progression in the post‐operative setting. Of the men that experience BCR after surgery, only a minority will experience progression to lethal prostate cancer in their lifetime. In order to improve treatment decisions, we sought to better characterize the genomics of patients with BCR who have metastatic disease progression. Methods and Material The expression profiles of three clinical outcome groups after radical prostatectomy (RP) were compared: NED (no evidence of disease, n = 108); BCR (PSA without metastasis, n = 163); and MET (metastasis, n = 192). The patients were profiled using Human Exon 1.0 ST microarrays and outcomes were supported by a median 18 years of follow‐up. A MET signature was defined and verified in an independent RP cohort to ensure the robustness of the signature. Furthermore, bioinformatics characterization of the signature was conducted to decipher its biology. Results Minimal gene expression differences were observed between adjuvant treatment naïve NED patients and BCR patients without metastasis. More than 95% of the differentially expressed genes (MET signature) were found in comparisons between primary tumors of MET patients and the two other outcome groups. The MET signature was validated in an independent cohort and was significantly associated with cell cycle genes, ubiquitin‐mediated proteolysis, DNA repair, androgen, G‐protein coupled and NOTCH signal transduction pathways. Conclusion This study shows that metastasis development after BCR is associated with a distinct transcriptional program that can be detected in the primary tumor. NED and BCR patients have highly similar transcriptional profiles, suggesting that measurement of PSA on its own is a poor surrogate for a lethal disease. Use of genomic testing in radical prostatectomy patients with initial PSA rise may be useful to improved secondary therapy decision‐making.

      Abstract: Objective To identify differences in demographic and socioeconomic factors between men seeking infertility evaluation and those undergoing vasectomy, in order to address disparities in access to these services. Patients and Methods Data from Cycle 6‐Cycle 7 (2002, 2006‐2008) of the National Survey of Family Growth (NSFG) was reviewed; the NSFG is a multi‐stage probability survey designed to capture a nationally representative sample of households with men and women 15 to 45‐years‐old in America. Variables analyzed included age, body mass index, self‐reported health, alcohol use, race, religious affiliation, marital status, number of offspring, educational attainment, income level, insurance status, and metropolitan home designation. Our primary outcome was correlation of these demographic and socioeconomic factors with evaluation for male infertility or vasectomy. Results Of the 11,067 men identified through the NSFG, 466 (4.2%) men sought infertility evaluation representing 2,187,455 men nationally and 326 (2.9%) had a vasectomy representing 1,510,386 men nationally. Those seeking infertility evaluation were more likely to be younger and have fewer children (p=0.001, 0.001) and less likely to be currently married (78% vs. 74%, p=0.010) or ever married (89% vs. 97%, p=0.002). Men undergoing a vasectomy were more likely to be Caucasian (86% vs. 70%, p=0.001). Men seeking infertility evaluation were more likely to have a college or graduate degree compared to men undergoing a vasectomy (68% vs. 64%, p=0.015). There was no difference between the 2 groups for all other variables. Conclusion While differences in demographic characteristics such as age, offspring number, and marital status were identified, measures of health, socioeconomic status, religion, and insurance were similar between men utilizing vasectomy and seeking infertility services. These factors help characterize utilization of male reproductive health services in the United States and may help address disparities in access to these services and improve public health strategies.

      Abstract: Objective To investigate the clinical utility of frozen section (FS) analysis performed during partial nephrectomy (PN) and its influence on intraoperative management. Patients and Methods We performed a retrospective analysis of consecutive PN cases from 2010‐2013. We evaluated the concordance between the intraoperative FS diagnosis and the FS control diagnosis, a postoperative quality assurance measure performed on all FS diagnoses after formalin fixation of the tissue. We also evaluated the concordance between the intraoperative FS diagnosis and the final specimen margin. Operative reports were reviewed for change in intraoperative management for cases with a positive or “atypia” FS diagnosis, or if the mass was sent for FS. Results 576 intraoperative FS were performed in 351 cases to assess the PN tumor bed margin, 19 (5.4%) of which also had a mass sent for FS to assess the tumor type. The concordance rate between the FS diagnosis and the FS control diagnosis was 98.3%. There were 30 (8.5%) final positive specimen margins, of which 4 (13.3%) were called “atypia”, 17 (56.7%) negative, and 9 (30%) positive on FS diagnosis. Intraoperative management was influenced in 6 of 9 cases with a positive FS diagnosis and in 1 of 9 cases with a FS diagnosis of “atypia.” Conclusions The relatively high false negative rate, controversy over the prognosis of a positive margin, and inconsistency in influencing intraoperative management, argues against the routine use of FS in PN cases.

      Abstract: Objectives To systematically review and create nomograms on flaccid and erect penile size measurements. Methods Study key eligibility criteria: measurement of penis size by a health professional using a standard procedure; a minimum of 50 participants per sample Exclusion criteria were samples with a congenital or acquired penile abnormality. previous surgery, complaint of small penis size or erectile dysfunction Synthesis methods: Calculation of a weighted mean and pooled standard deviation and simulation of 20,000 observations from the normal distribution to generate nomograms of penis size. Results Nomograms for flaccid pendulous (n = 10,704, mean 9.16cm, sd 1.57) and stretched length (n=14,160, mean 13.24cm, sd 1.89), erect length (n = 692, mean 13.12cm, sd 1.66), flaccid circumference (n = 9,407, mean 9.31cm, sd 0.90); and erect circumference (n = 381, mean 11.66cm, sd 1.10) were constructed. Consistent and strongest significant correlation was between flaccid stretched or erect length and height, which ranged from r = 0.2 to 0.6. Conclusions penis size nomograms may be useful in clinical and therapeutic settings to counsel men and for academic research. Limitations: a relatively small number of erect measurements were conducted in a clinical setting and the greatest variability between studies was with flaccid stretched length.

      Abstract: Study Objectives To assess potential complications associated with ILND across international tertiary care referral centers, and determine prognostic factors that best predict development of these complications. Materials/Methods A retrospective chart review was conducted across 4 international cancer centers. The study population of 327 patients underwent diagnostic/therapeutic ILND. The endpoint was the overall incidence of complications and their respective severity (major/minor). The Clavien‐Dindo classification system was used to standardize reporting of complications. Results 181 patients (55.4%) had a post‐operative complication, with minor complications in 119 cases (65.7%) and major in 62 (34.3%). The total number of lymph nodes removed was an independent predictor of experiencing any complication, while the median number of lymph nodes removed was an independent predictor of major complications. The AJCC stage was an independent predictor of all wound infections, while the patient's age, ILND with Sartorius flap transposition, and surgery performed prior to year 2008 were independent predictors of major wound infections. Conclusions This is the largest report of complication rates following ILND for SCCP and shows that the majority of complications associated with ILND are minor and resolve without prolonged morbidity. Variables pertaining to the extent of disease burden have been found to be prognostic of increased post‐operative morbidity.

      Abstract: Objectives To assess face, content and construct validity, and feasibility and acceptability of the GreenLight™ Simulator as a training tool for photoselective vaporisation of the prostate (PVP), and to establish learning curves and develop an evidence‐based training curriculum. Subjects and Methods This prospective, observational and comparative study, recruited novice (25 participants), intermediate (14) and expert‐level urologists (seven) from the UK and Europe at the 28th European Association of Urological Surgeons Annual Meeting 2013. A group of novices (12 participants) performed 10 sessions of subtask training modules followed by a long operative case, whereas a second group (13) performed five sessions of a given case module. Intermediate and expert groups performed all training modules once, followed by one operative case. The outcome measures for learning curves and construct validity were time to task, coagulation time, vaporisation time, average sweep speed, average laser distance, blood loss, operative errors, and instrument cost. Face and content validity, feasibility and acceptability were addressed through a quantitative survey. Results Construct validity was demonstrated in two of five training modules (P = 0.038; P = 0.018) and in a considerable number of case metrics (P = 0.034). Learning curves were seen in all five training modules (P < 0.001) and significant reduction in case operative time (P < 0.001) and error (P = 0.017) were seen. An evidence‐based training curriculum, to help trainees acquire transferable skills, was produced using the results. Conclusion This study has shown the GreenLight Simulator to be a valid and useful training tool for PVP. It is hoped that by using the training curriculum for the GreenLight Simulator, novice trainees can acquire skills and knowledge to a predetermined level of proficiency.

      Abstract: Objective To objectively assess ipsilateral renal function (IRF) preservation and factors influencing it after robot‐assisted partial nephrectomy (RAPN). Patients and Methods Our database was queried to identify patients who had undergone RAPN from 2007 to 2013 and had complete pre‐ and postoperative mercapto‐acetyltriglycine (MAG3) renal scan assessment. The estimated glomerular filtration rate (eGFR) for the operated kidney was calculated by multiplying the percentage of contribution from the renal scan by the total eGFR. IRF preservation was defined as a ratio of the postoperative eGFR for the operated kidney to the preoperative eGFR for the operated kidney. The percentage of total eGFR preservation was calculated in the same manner (postoperative eGFR/preoperative eGFR × 100). The amount of healthy rim of renal parenchyma removed was assessed by deducting the volume of tumour from the volume of the PN specimen assessed on pathology. Multivariable linear regression was used for analysis. Results In all, 99 patients were included in the analysis. The overall median (interquartile range) total eGFR preservation and IRF preservation for the operated kidney was 83.83 (75.2–94.1)% and 72 (60.3–81)%, respectively (P < 0.01). On multivariable analysis, volume of healthy rim of renal parenchyma removed, warm ischaemia time (WIT) > 30 min, body mass index (BMI) and operated kidney preoperative eGFR were predictive of IRF preservation. Conclusions Using total eGFR tends to overestimate the degree of renal function preservation after RAPN. This is particularly relevant when studying factors affecting functional outcomes after nephron‐sparing surgery. IRF may be a more precise assessment method in this setting. Operated kidney baseline renal function, BMI, WIT >30 min, and amount of resected healthy renal parenchyma represent the factors with a significant impact on the IRF preservation. RAPN provides significant preservation of renal function as shown by objective assessment criteria.

  • Clinical significance of prognosis using the neutrophil–lymphocyte
           ratio and erythrocyte sedimentation rate in patients undergoing radical
           nephroureterectomy for upper urinary tract urothelial carcinoma
    • Authors: Hyun Hwan Sung; Hwang Gyun Jeon, Byong Chang Jeong, Seong Il Seo, Seong Soo Jeon, Han‐Yong Choi, Hyun Moo Lee
      Pages: n/a - n/a
      Abstract: Objectives To evaluate the clinical significance of preoperative erythrocyte sedimentation rate (ESR) and neutrophil–lymphocyte ratio (NLR) as prognostic factors in patients undergoing radical nephroureterectomy for upper tract urothelial carcinoma (UTUC). Patients and Methods A total of 410 patients were retrospectively reviewed. An elevated NLR was defined as ≥2.5 and a normal ESR was considered to be in the range of 0–22 mm/h in men and 0–27 mm/h in women. Patients were divided into three groups: those with ESR and NLR in the normal range (group 0, n = 168), those with either elevated ESR or elevated NLR (group I, n = 169), and those with both elevated ESR and elevated NLR (group II, n = 73). Results The median patient age was 64 years and the median follow‐up duration was 40.2 months. In all, 35.6 and 41.2% of patients had elevated NLRs and ESRs, respectively. Group II was associated with advanced tumour status in terms of size, grade, stage, lymph node and margin status (P < 0.05). Preoperative ESR (hazard ratio [HR] 1.784, 95% confidence interval [CI] 1.173–2.712), NLR (HR 1.704, 95% CI 1.136–2.556), and prognostic grouping (HR 2.285, 95% CI 1.397–3.737 for group I; HR 2.962, 95% CI 1.719–5.102 for group II) were independent predictors of progression‐free survival (PFS) in the multivariate model (P < 0.05). Prognostic grouping was also an independent prognostic factor for cancer‐specific survival (CSS) and overall survival (OS). Time‐dependent area under the receiver‐operating characteristic curves showed that NLR plus ESR had a greater diagnostic value than NLR alone regarding oncological outcomes (P < 0.05). Conclusions Prognostic grouping using ESR and NLR was identified as an independent prognostic marker in patients with UTUC. The addition of ESR improved the prognostic value of NLR alone in predicting oncological outcomes. The combination of preoperative ESR and NLR might be a new prediction tool in patients with UTUC after radical nephroureterectomy.

  • Incidence of urethral stricture after bipolar transurethral resection of
           the prostate using TURis: results from a randomised trial
    • Authors: Kazumasa Komura; Teruo Inamoto, Tomoaki Takai, Taizo Uchimoto, Kenkichi Saito, Naoki Tanda, Koichiro Minami, Rintaro Oide, Hirofumi Uehara, Kiyoshi Takahara, Hajime Hirano, Hayahito Nomi, Satoshi Kiyama, Toshikazu Watsuji, Haruhito Azuma
      Abstract: Objectives To assess whether bipolar transurethral resection of the prostate (B‐TURP) using the TURis® system has a similar level of efficacy and safety to that of the traditional monopolar transurethral resection of the prostate (M‐TURP), and to evaluate the impact of the TURis system on postoperative urethral stricture rates over a 36‐month follow‐up period. Patients and Methods A total of 136 patients with benign prostatic obstruction were randomised to undergo either B‐TURP using the TURis system or conventional M‐TURP, and were regularly followed for 36 months after surgery. The primary endpoint was safety, which included the long‐term complication rates of postoperative urethral stricture. The secondary endpoint was the follow‐up measurement of efficacy. Results In peri‐operative findings, no patient in either treatment group presented with transurethral resection syndrome, and the decline in levels of haemoglobin and hematocrit were similar. The mean operation time was significantly extended in the TURis treatment group compared with the M‐TURP group (79.5 vs 68.6 min; P = 0.032) and postoperative clot retention was more likely to be seen after M‐TURP (P = 0.044). Similar efficacy findings were maintained throughout 36 months, but a significant difference in postoperative urethral stricture rates between groups was detected (6.6% in M‐TURP vs 19.0% in TURis; P = 0.022). After stratifying patients according to prostate volume, there was no significant difference between the two treatment groups with regard to urethral stricture rates in patients with a prostate volume ≤ 70 mL (3.8% in M‐TURP vs 3.8% in TURis), but in the TURis group there was a significantly higher urethral stricture rate compared with the M‐TURP group in patients with a prostate volume >70 mL (20% in TURis vs 2.2% in M‐TURP; P = 0.012). Furthermore, the mean operation time for TURis was significantly longer than for M‐TURP for the subgroup of patients with a prostate volume > 70 mL (99.6 vs 77.2 min; P = 0.011), but not for the subgroup of patients with a prostate volume ≤ 70 mL. Conclusion The TURis system seems to be as efficacious and safe as conventional M‐TURP except that there was a higher incidence of urethral stricture in patients with larger preoperative prostate volumes.

  • Cytotoxic chemotherapy in the contemporary management of metastatic
           castration‐resistant prostate cancer (mCRPC)
    • Authors: Guru Sonpavde; Christopher G. Wang, Matthew D. Galsky, William K. Oh, Andrew J. Armstrong
      Abstract: For several years, docetaxel was the only treatment shown to improve survival of patients with metastatic castration‐resistant prostate cancer (mCRPC). There are now several novel agents available, although chemotherapy with docetaxel and cabazitaxel continues to play an important role. However, the increasing number of available agents will inevitably affect the timing of chemotherapy and therefore it may be important to offer this approach before declining performance status renders patients ineligible for chemotherapy. Patient selection is also important to optimise treatment benefit. The role of predictive biomarkers has assumed greater importance due to the development of multiple agents and resistance to available agents. In addition, the optimal sequence of treatments remains undefined and requires further study in order to maximize long‐term outcomes. We provide an overview of the clinical data supporting the role of chemotherapy in the treatment of mCRPC and the emerging role in metastatic castration‐sensitive prostate cancer. We review the key issues in the management of patients including selection of patients for chemotherapy, when to start chemotherapy, and how best to sequence treatments to maximise outcomes. In addition, we briefly summarise the promising new chemotherapeutic agents in development in the context of emerging therapies.

  • Medium‐term oncological outcomes for extended vs saturation biopsy
           and transrectal vs transperineal biopsy in active surveillance for
           prostate cancer
    • Authors: James E. Thompson; Andrew Hayen, Adam Landau, Anne‐Maree Haynes, Arveen Kalapara, Joseph Ischia, Jayne Matthews, Mark Frydenberg, Phillip D. Stricker
      Abstract: Objective To assess, in men undergoing active surveillance (AS) for low‐risk prostate cancer, whether saturation or transperineal biopsy altered oncological outcomes, compared with standard transrectal biopsy. Patients and Methods Retrospective analysis of prospectively collected data from two cohorts with localised prostate cancer (1998–2012) undergoing AS. Prostate cancer‐specific, metastasis‐free and treatment‐free survival, unfavourable disease and significant cancer at radical prostatectomy (RP) were compared for standard (12 core, median 16), and transrectal vs transperineal biopsy, using multivariate analysis. Results In all, 650 men were included in the analysis with a median (mean) follow‐up of 55 (67) months. Prostate cancer‐specific, metastasis‐free and biochemical recurrence‐free survival were 100%, 100% and 99% respectively. Radical treatment‐free survival at 5 and 10 years were 57% and 45% respectively (median time to treatment 7.5 years). On Kaplan–Meier analysis, saturation biopsy was associated with increased objective biopsy progression requiring treatment (log‐rank P = 0.01). On multivariate Cox proportional hazards analysis, saturation biopsy (hazard ratio 1.68, P < 0.01) but not transperineal approach (P = 0.89) was associated with increased objective biopsy progression requiring treatment. On logistic regression analysis of 179 men who underwent RP for objective progression, transperineal biopsy was associated with lower likelihood of unfavourable RP pathology (odds ratio 0.42, P = 0.03) but saturation biopsy did not alter the likelihood (P = 0.25). Neither transperineal nor saturation biopsy altered the likelihood of significant vs insignificant cancer at RP (P = 0.19 and P = 0.41, respectively). Conclusions AS achieved satisfactory oncological outcomes. Saturation biopsy increased progression to treatment on AS; longer follow‐up is needed to determine if this represents beneficial earlier detection of significant disease or over‐treatment. Transperineal biopsy reduced the likelihood of unfavourable disease at RP, possibly due to earlier detection of anterior tumours.

  • Long‐term functional outcomes after artificial urinary sphincter
           implantation in men with stress urinary incontinence
    • Authors: Priscilla Léon; Emmanuel Chartier‐Kastler, Morgan Rouprêt, Vanina Ambrogi, Pierre Mozer, Véronique Phé
      Abstract: Objective To evaluate long‐term functional outcomes of artificial urinary sphincters (AUSs) and to determine how many men required explantation because of stress urinary incontinence (SUI) caused by sphincter deficiency after prostate surgery. Patients and Methods Men who had undergone placement of an AUS (American Medical Systems AMS 800®) between 1984 and 1992 to relieve SUI caused by sphincter deficiency after prostate surgery were included. Continence, defined as no need for pads, was assessed at the end of the follow‐up. Kaplan–Meier survival curves estimated the survival rate of the device without needing explantation or revision. Results In all, 57 consecutive patients were included with a median (interquartile range, IQR) age of 69 (64–72) years. The median (IQR) duration of follow‐up was 15 (8.25–19.75) years. At the end of follow‐up, 25 patients (43.8%) still had their primary AUS. The AUS was explanted in nine men because of erosion (seven) and infection (two). Survival rates, without AUS explantation, were 87%, 87%, 80%, and 80% at 5, 10, 15, and 20 years, respectively. Survival rates, without AUS revision, were 59%, 28%, 15%, and 5% at 5, 10, 15, and 20 years, respectively. At the end of the follow‐up, in intention‐to‐treat analysis, 77.2% of patients were continent. Conclusion In the long term (>10 years) the AMS 800 can offer a high rate of continence to men with SUI caused by sphincter deficiency, with a tolerable rate of explantation and revision.

  • Evaluation of functional outcomes after laparoscopic partial nephrectomy
           using renal scintigraphy: clamped vs clampless technique
    • Authors: Francesco Porpiglia; Riccardo Bertolo, Daniele Amparore, Valerio Podio, Tiziana Angusti, Andrea Veltri, Cristian Fiori
      Abstract: Objectives To examine differences in postoperative renal functional outcomes when comparing clampless with conventional laparoscopic partial nephrectomy (LPN) by using renal scintigraphy, and to identify the predictors of poorer postoperative renal functional outcomes after clampless LPN. Patients and Methods Between September 2010 and September 2012, 87 patients with renal masses suitable for LPN were prospectively enrolled in the study. From September 2010 to September 2011, LPN with renal artery clamping was performed and from September 2011 to September 2012 clampless LPN (no clamping of renal artery) was performed. Patients who underwent clampless LPN were unselected and consecutive, and the procedure was performed at the end of surgeon's learning curve. Patients were divided into two groups according to warm ischaemia time (WIT): group A, conventional LPN and group B, clampless‐LPN (WIT = 0 min). Demographic and peri‐operative data were collected and analysed and functional outcomes were evaluated using biochemical markers and renal scintigraphy at baseline and at 3 months after surgery. The percentage loss of renal function, evaluated according to renal scintigraphy, was calculated. Chi‐squared and Student's t‐tests were carried out and regression analysis was performed. Results Group A was found to be similar to group B in all variables measured except for WIT and blood loss (P < 0.001). The percentage reduction in renal scintigraphy values was not significantly different between the groups (reductions of 5% in group A and 6% in group B for split renal function [SRF] and 12% in group A and 17% in group B for estimated renal plasmatic flow [ERPF]; P = 0.587 and P = 0.083, respectively). Multivariate analysis in group B showed that the lower the baseline values of SRF and ERPF, the poorer the postoperative functional outcome of the treated kidney. Conclusions In our experience, even clampless LPN was not found to be functionally harmless. The patients who benefitted most from a clampless approach were those with the poorest baseline renal function.

  • Incidence of needle‐tract seeding following prostate biopsy for
           suspected cancer: a review of the literature
    • Authors: Dimitrios Volanis; David E. Neal, Anne Y. Warren, Vincent J. Gnanapragasam
      Abstract: With the widespread clinical use of prostate‐specific antigen (PSA), biopsy of the prostate has become one of the most commonly performed urological procedures. In general it is well tolerated, although there is some morbidity and risk of infection. In recent years, there have been increasing concerns that prostate biopsy may lead to tumour seeding along the needle tract. The aim of the present paper was to review the evidence on the prevalence of tumour seeding after prostate biopsy and to define the risk of this event in the context of current clinical practice. A PubMed literature search was conducted in January 2014 according to the Preferred Reporting Items for Systematic Reviews and Meta‐analysis (PRISMA) statement. Literature was examined with emphasis on the incidence of seeding, clinical presentation and on risk factors including type of needle used, transrectal vs transperineal approach, as well as tumour grade and stage. In all, 26 publications were identified reporting needle‐tract seeding after prostate biopsy. In all, 42 patients with needle‐tract seeding were identified. In most cases, seeding was reported after transperineal biopsy of the prostate, while nine cases occurred after transrectal biopsy. Based on the reviewed series the incidence of seeding appears to be

  • Contemporary practice and technique‐related outcomes for radical
           prostatectomy in the UK: a report of national outcomes
    • Authors: Alexander Laird; Sarah Fowler, Daniel W. Good, Grant D. Stewart, Vaikuntam Srinivasan, Declan Cahill, Simon F. Brewster, S. Alan McNeill,
      Abstract: Objective To determine current radical prostatectomy (RP) practice in the UK and compare surgical outcomes between techniques. Patients and Methods All RPs performed between 1 January 2011 and 31 December 2011 in the UK with data entered into the British Association of Urological Surgeons (BAUS) database, were identified for analysis. Overall surgical outcomes were assessed and subgroup analyses of these outcomes, based on operative technique [open RP (ORP), laparoscopic RP (LRP) and robot‐assisted laparoscopic RP (RALP)], were made. Continuous variables were compared using the Mann–Whitney U‐test and categorical variables using the Pearson chi‐squared test. Univariate and multivariate binary regression analyses were performed to assess the effect of patient, surgeon and technique‐related variables on surgical outcomes. Results During the study period 2163 RPs were performed by 115 consultants with a median (range) of 11 (1–154) cases/consultant. Most RPs were performed laparoscopically (ORP 25.8%, LRP 54.6%, RALP 19.6%) and those performing minimally invasive techniques are more likely to have a higher annual case volume with 50 cases/year. Most patients were classified as having intermediate‐ or high‐risk disease preoperatively (1596 patients, 82.5%) and this increased to 97.2% (1649) on postoperative risk stratification. The overall intraoperative complication rate was 14.2% and was significantly greater for LRP (17.8%) vs ORP (8.2%) and RALP (12.4%), (P < 0.001). In all, 71% of patients had an estimated blood loss (EBL) of 500, > 1000 and >2000 mL EBL compared with the other techniques (P < 0.001). The postoperative complication rate was 10.7% overall, with a significantly greater postoperative complication rate in the LRP group (LRP 14.6%, ORP 8.8% and RALP 10.3% respectively, P = 0.007). Positive surgical margin (PSM) rates were 17.5% for pT2 disease and 42.3% for pT3 disease. The PSM rate was significantly lower in the RALP patients compared with the ORP patients for those with pT2 disease (P = 0.025), while there was no difference between ORP and LRP (ORP 21.7%, LRP 18.1% and RALP 13.0%). There was no significant difference in the PSM rate in pT3 disease between surgical techniques. Conclusion Most RPs in the UK are performed using minimally invasive techniques, which offer reduced blood loss and transfusion rates compared with ORP. The operation time, complication rate, PSM rates, and association with higher volume practice support RALP as the minimally invasive technique of choice, which could have implications for regions without access to such services. The disparity in outcomes between this national study and high‐volume single centres, most probably reflects the low median national case volume, and combined with the positive effect of high case volume on multivariate analysis of surgical outcomes and PSM rates, strengthens the argument for centralisation of services.

  • Long‐term follow‐up of a multicentre randomised controlled
           trial comparing tension‐free vaginal tape, xenograft and autologous
           fascial slings for the treatment of stress urinary incontinence in women
    • Authors: Zainab A. Khan; Arjun Nambiar, Roland Morley, Christopher R. Chapple, Simon J. Emery, Malcolm G. Lucas
      Abstract: Objective To compare the long‐term outcomes of a tension‐free vaginal tape (TVT; Gynecare™, Somerville, NJ, USA), autologous fascial sling (AFS) and xenograft sling (porcine dermis, Pelvicol™; Bard, Murray Hill, NJ, USA) in the management of female stress urinary incontinence (SUI). Patients and Methods A multicentre randomised controlled trial carried out in four UK centres from 2001 to 2006 involving 201 women requiring primary surgery for SUI. The women were randomly assigned to receive TVT, AFS or Pelvicol. The primary outcome was surgical success defined as ‘women reporting being completely ‘dry’ or ‘improved’ at the time of follow‐up’. The secondary outcomes included ‘completely dry’ rates, changes in the Bristol Female Lower Urinary Tract Symptoms (BFLUTS) and EuroQoL EQ‐5D questionnaire scores. Results In all, 162 (80.6%) women were available for follow‐up with a median (range) duration of 10 (6.6–12.6) years. ‘Success’ rates for TVT, AFS and Pelvicol were 73%, 75.4% and 58%, respectively. Comparing the 1‐ and 10‐year ‘success’ rates, there was deterioration from 93% to 73% (P < 0.05) in the TVT arm and 90% to 75.4% (P < 0.05) in the AFS arm; ‘dry’ rates were 31.7%, 50.8% and 15.7%, respectively. Overall, the ‘dry’ rates favoured AFS when compared with Pelvicol (P < 0.001) and TVT (P = 0.036). The re‐operation rate for persistent SUI was 3.2% (two patients) in the TVT arm, 13.1% (five) in the Pelvicol arm, while none of the patients in the AFS arm required further intervention. Conclusions Our study indicates there is not enough evidence to suggest a difference in long‐term success rates between AFS and TVT. However, there is some evidence that ‘dry’ rates for AFS may be more durable than TVT.

  • Role of emergency ureteroscopy in the management of ureteric stones:
           analysis of 394 cases
    • Authors: Kamran Zargar‐Shoshtari; William Anderson, Michael Rice
      Abstract: Objective To analyse the outcomes of emergency ureteroscopy (URS) cases performed in Auckland City Hospital. Methods We conducted a retrospective review of all emergency URS procedures performed at Auckland City Hospital between 1 January 2010 and 31 December 2011. Data on patients, stones and procedures were collected and analysed. Emergency URS failure was defined as fragments >3 mm or the need for a repeat procedure. Results A total of 499 URS procedures were identified. Of these 394 (79%) were emergency procedures. The mean (sd; range) patient age was 48 (16; 13–88) years. In all, 83% of emergency URS cases had an American Society of Anesthesiologists (ASA) score of 1 or 2, 25% of stones were >9 mm, with a mean (sd) size of 8 (4) mm, and 285 procedures (72%) were successful. These patients were younger (47 vs 51 years), were more likely to have an ASA score of 1 (103 patients in the successful treatment group vs 26 in the failed treatment group), had smaller stones (7 vs 9 mm) and were more likely to have distal stones (P < 0.05). A total of 20 complications (5%) were recorded including six false passages and three mucosal injuries, one of which required radiological intervention, and 50 patients (13%) re‐presented, for pain (76%), bleeding (10%) or infection (14%). Conclusion We showed that emergency URS is a feasible approach for the routine management of acute ureteric colic with a low complications rate. A subgroup of younger, healthier patients may benefit the most from the procedure.

  • Diagnostic accuracy of magnetic resonance imaging (MRI) prostate imaging
           reporting and data system (PI‐RADS) scoring in a transperineal
           prostate biopsy setting
    • Authors: Alistair D.R. Grey; Manik S. Chana, Rick Popert, Konrad Wolfe, Sidath H. Liyanage, Peter L. Acher
      Abstract: Objectives To determine the sensitivity and specificity of multiparametric magnetic resonance imaging (mpMRI) for significant prostate cancer with transperineal sector biopsy (TPSB) as the reference standard. Patients and Methods The study included consecutive patients who presented for TPSB between July 2012 and November 2013 after mpMRI (T2‐ and diffusion‐weighted images, 1.5 Tesla scanner, 8‐channel body coil). A specialist uro‐radiologist, blinded to clinical details, assigned qualitative prostate imaging reporting and data system (PI‐RADS) scores on a Likert‐type scale, denoting the likelihood of significant prostate cancer as follows: 1, highly unlikely; 3, equivocal; and 5, highly likely. TPSBs sampled 24–40 cores (depending on prostate size) per patient. Significant prostate cancer was defined as the presence of Gleason pattern 4 or cancer core length ≥6 mm. Results A total of 201 patients were included in the analysis. Indications were: a previous negative transrectal biopsy with continued suspicion of prostate cancer (n = 103); primary biopsy (n = 83); and active surveillance (n = 15). Patients' mean (±sd) age, prostate‐specific antigen and prostate volumes were 65 (±7) years, 12.8 (±12.4) ng/mL and 62 (±36) mL, respectively. Overall, biopsies were benign, clinically insignificant and clinically significant in 124 (62%), 20 (10%) and 57 (28%) patients, respectively. Two of 88 men with a PI‐RADS score of 1 or 2 had significant prostate cancer, giving a sensitivity of 97% (95% confidence interval [CI] 87–99) and a specificity of 60% (95% CI 51–68) at this threshold. Receiver–operator curve analysis gave an area under the curve of 0.89 (95% CI 0.82–0.92). The negative predictive value of a PI‐RADS score of ≤2 for clinically significant prostate cancer was 97.7% Conclusion We found that PI‐RADS scoring performs well as a predictor for biopsy outcome and could be used in the decision‐making process for prostate biopsy.

  • Lack of association of joint hypermobility with urinary incontinence
           subtypes and pelvic organ prolapse
    • Authors: Alex Derpapas; Rufus Cartwright, Purnima Upadhyaya, Alka A. Bhide, Alex G. Digesu, Vik Khullar
      Abstract: Objective To test the hypothesis that joint hypermobility (JHM) is associated with specific urinary incontinence (UI) subtypes and uterovaginal prolapse. Patients and Methods In all, 270 women scheduled to undergo urodynamic investigations were invited to self‐complete a validated five‐item JHM questionnaire. Women underwent history taking, symptoms assessing via the King's Health Questionnaire and clinical examination using the Pelvic Organ Prolapse Quantification system. Associations between JHM and pelvic floor disorders in univariate and multivariate ordinal regression were reported using odds ratios (ORs) and 95% confidence intervals (CIs). Results The prevalence of JHM was 31.1%. JHM had a negative association with age (OR 0.98/year, P = 0.04). There was no association between JHM and either urodynamic (P = 0.41), or symptomatic stress UI (P = 0.48). Nor was there association with detrusor overactivity or symptomatic urgency UI. Multivariate ordinal regression of JHM with maximum prolapse stage, adjusting for age, showed a significant relationship (OR 1.26/stage, 95% CI 1.06–1.46, P < 0.05). Conclusion Although JHM is highly prevalent amongst women with lower urinary tract symptoms (LUTS), there is no strong association of JHM with any UI subtype. There is a trend towards higher prolapse staging in women with JHM, which becomes significant only after adjustment for the confounding negative association between age and JHM.

  • Safety and diagnostic accuracy of percutaneous biopsy in upper tract
           urothelial carcinoma
    • Authors: Steven Y. Huang; Kamran Ahrar, Sanjay Gupta, Michael J. Wallace, Joe E. Ensor, Savitri Krishnamurthy, Surena F. Matin
      Abstract: Objective To assess the diagnostic accuracy and safety of percutaneous biopsy for upper tract urothelial carcinoma (UTUC). Patients and Methods From 2002 to 2013, 26 upper tract lesions in 24 patients (20 men; median [range] age 67.8 [51.7–85.9] years) were percutaneously biopsied. Analysis was separated based on lesion appearance: (i) mass infiltrating renal parenchyma, (ii) filling defect in the collecting system, (iii) urothelial wall thickening. We tracked immediate complications and tract seeding on follow‐up imaging. Results Of the 26 upper tract lesions, 15 (58%) were masses infiltrating the renal parenchyma (mean [range] size 5.4 [1.1–14.0] cm), six (23%) were urothelial wall thickenings (mean [range] size 0.8 [0.4–1.1] cm), and five (19%) were filling defects within the renal pelvis or calyx (mean [range] size 2.7 [1.0–4.6] cm). Definitive diagnosis of UTUC was made by biopsy in 22 of 26 lesions (85%). Biopsy characterised 14 of 15 infiltrative masses and five of five filling defects; biopsy characterised three of six cases of urothelial wall thickening. CT follow‐up was available for 19 patients (73%) at a median (range) of 13.6 (1.0–98.9) months. Three patients (11%) developed recurrence in the nephrectomy bed at 5.6, 9.7, and 29.0 months after biopsy; none were attributed to tract seeding after independent review, because recurrence was remote from the biopsy site. Conclusion Percutaneous biopsy is effective for diagnosis of UTUC, providing tissue diagnosis in 85% of cases. While case reports cite a risk of tract seeding, no cases of recurrence were definitely attributable to percutaneous biopsy. Thus, for upper tract urothelial lesions, which are not amenable to endoscopic biopsy, percutaneous biopsy is a safe and effective technique.

  • Metabolic syndrome‐like components and prostate cancer risk: results
           from the Reduction by Dutasteride of Prostate Cancer Events (REDUCE) study
           
    • Authors: Katharine N. Sourbeer; Lauren E. Howard, Gerald L. Andriole, Daniel M. Moreira, Ramiro Castro‐Santamaria, Stephen J. Freedland, Adriana C. Vidal
      Abstract: Objective To evaluate the relationship between number of metabolic syndrome (MetS)‐like components and prostate cancer diagnosis in a group of men where nearly all biopsies were taken independent of prostate‐specific antigen (PSA) level, thus minimising any confounding from how the various MetS‐like components may influence PSA levels. Subjects/Patients and Methods We analysed data from 6426 men in the Reduction by Dutasteride of Prostate Cancer Events (REDUCE) study with at least one on‐study biopsy. REDUCE compared dutasteride vs placebo on prostate cancer risk among men with an elevated PSA level and negative pre‐study biopsy and included two on‐study biopsies regardless of PSA level at 2 and 4 years. Available data for MetS‐like components included data on diabetes, hypertension, hypercholesterolaemia, and body mass index. The association between number of these MetS‐like components and prostate cancer risk and low‐grade (Gleason sum 7) vs no prostate cancer was evaluated using logistic regression. Results In all, 2171 men (34%) had one MetS‐like component, 724 (11%) had two, and 163 (3%) had three or four. Men with more MetS‐like components had lower PSA levels (P = 0.029). One vs no MetS‐like components was protective for overall prostate cancer (P = 0.041) and low‐grade prostate cancer (P = 0.010). Two (P = 0.69) or three to four (P = 0.15) MetS‐like components were not significantly related to prostate cancer. While one MetS‐like component was unrelated to high‐grade prostate cancer (P = 0.97), two (P = 0.059) or three to four MetS‐like components (P = 0.02) were associated with increased high‐grade prostate cancer risk, although only the latter was significant. Conclusion When biopsies are largely PSA level independent, men with an initial elevated PSA level and a previous negative biopsy, and multiple MetS‐like components were at an increased risk of high‐grade prostate cancer, suggesting the link between MetS‐like components and high‐grade prostate cancer is unrelated to a lowered PSA level.

  • The scientific basis for the use of biomaterials in stress urinary
           incontinence (SUI) and pelvic organ prolapse (POP)
    • Authors: Marc Colaco; Jayadev Mettu, Gopal Badlani
      Abstract: Objectives To review the scientific and clinical literature to assess the basis for the use of biomaterials in stress urinary incontinence (SUI) and pelvic organ prolapse (POP). Pelvic floor diseases (PFDS), such as SUI and POP, are common and vexing disorders. While synthetic mesh‐based repairs have long been considered an option for PFD treatment, and their efficacy established in randomised clinical trials, safety of its use has recently been called into question. Materials and Methods Using the PubMed, MEDLINE and Medical Subject Headings (MeSH) databases, we performed a critical review of English‐language publications that contained the following keywords: ‘pelvic organ prolapse’, ‘stress urinary incontinence’, ‘mesh’, ‘biomaterial’, ‘collagen’, ‘elastin’ and ‘extracellular matrix’. After reviewing for relevance for mesh use in the pelvis by two independent reviewers with a third available in the case of disagreement, a total of 60 articles were included in the present review. Results We found that many of the potential causes of PFDs are due to altered metabolism of patient extracellular matrix (specifically collagen, elastin, and their respective enzymes) and as such, repairs using native tissue may suffer from the same abnormalities leading to a subsequent lack of repair integrity. However, mesh use is not without its unique risks. Several publications have suggested that biomaterials may undergo alteration after implantation, but these findings have not been demonstrated in the normal milieu. Conclusion While the decision for the use of synthetic mesh is scientifically sound, its benefits and risks must be discussed with the patient in an informed decision‐making process.

  • A new one‐layer epididymovasostomy technique
    • Authors: Alayman Hussein
      Abstract: Objectives To describe and evaluate the outcomes of a new epididymovasostomy technique. Patients and Methods Nine patients with obstructive azoospermia were treated at the Minia University Hospital using a new microsurgical bilateral epididymovasostomy technique. The technique involved the opening of a small window in the tunica of the epididymis, making an opening in the underneath epididymal tubule and keeping it open by fixing the edges of the epididymal opening to the edge of the epididymal tunica with four 10/0 nylon sutures. The abdominal cut end of the vas deferens was then anastomosed to the epididymal opening by suturing the epididymal tubule, fixed to its tunica in one layer, to the full thickness vas deferens. The main outcome measure was finding sperm in the ejaculate. Results Sperm was found in the ejaculate in six out of nine patients after our new, one‐layer, epididymovasostomy technique. Mean ± sd operating time was 176 ± 23 min. Conclusions This new, one‐layer, epididymovasostomy technique provides a simple alternative method of epididymovasostomy, with reasonable outcomes. More cases and follow‐up are needed to make meaningful comparisons with conventional epididymovasostomy.

  • Burden of male lower urinary tract symptoms (LUTS) suggestive of benign
           prostatic hyperplasia (BPH) – focus on the UK
    • Authors: Mark Speakman; Roger Kirby, Scott Doyle, Chris Ioannou
      Abstract: Key Messages Lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH) can be bothersome and negatively impact on a patient's quality of life (QoL). As the prevalence of LUTS/BPH increases with age, the burden on the healthcare system and society may increase due to the ageing population. This review unifies literature on the burden of LUTS/BPH on patients and society, particularly in the UK. LUTS/BPH is associated with high personal and societal costs, both in direct medical costs and indirect losses in daily functioning, and through its negative impact on QoL for patients and partners. LUTS/BPH is often underdiagnosed and undertreated. Men should be encouraged to seek medical advice for this condition and should not accept it as part of ageing, while clinicians should be more active in the identification and treatment of LUTS/BPH. To assess the burden of illness and unmet need arising from lower urinary tract symptoms (LUTS) presumed secondary to benign prostatic hyperplasia (BPH) from an individual patient and societal perspective with a focus on the UK. Embase, PubMed, the World Health Organization, the Cochrane Database of Systematic Reviews and the York Centre for Reviews and Dissemination were searched to identify studies on the epidemiological, humanistic or economic burden of LUTS/BPH published in English between October 2001 and January 2013. Data were extracted and the quality of the studies was assessed for inclusion. UK data were reported; in the absence of UK data, European and USA data were provided. In all, 374 abstracts were identified, 104 full papers were assessed and 33 papers met the inclusion criteria and were included in the review. An additional paper was included in the review upon a revision in 2014. The papers show that LUTS are common in the UK, affecting ≈3% of men aged 45–49 years, rising to >30% in men aged ≥85 years. European and USA studies have reported the major impact of LUTS on quality of life of the patient and their partner. LUTS are associated with high personal and societal costs, both in direct medical costs and indirect losses in daily functioning. While treatment costs in the UK are relatively low compared with other countries, the burden on health services is still substantial. LUTS associated with BPH is a highly impactful condition that is often undertreated. LUTS/BPH have a major impact on men, their families, health services and society. Men with LUTS secondary to BPH should not simply accept their symptoms as part of ageing, but should be encouraged to consult their physicians if they have bothersome symptoms.

      Abstract: Objective To assess the safety and efficacy of abiraterone acetate (AA) in patients with metastatic castration‐resistant prostate cancer (mCRPC) treated in a compassionate named patient programme (NPP). Patients and Methods We retrospectively reviewed the clinical records of patients with mCRPC treated with AA at the standard daily oral dose of 1000 mg plus prednisone 10 mg/day in 19 Italian hospitals. Results We assessed 265 patients with mCRPC treated with AA. The most frequent (>1%) grade 3–4 toxicities were anaemia (4.2%), fatigue (4.2%), and bone pain (1.5%). The median progression‐free survival was 7 months; median overall survival was 17 months after starting AA, and 35 months after the first docetaxel administration. Our study reproduced the clinical outcomes reported in the AA pivotal trial, including those relating to special populations such as the elderly, patients with a poor performance status, symptomatic patients, and patients with visceral metastases. Conclusions Our data show the safety and activity of AA when administered outside clinical trials, and confirm the findings of the post‐docetaxel pivotal trial in the patients as a whole population and in special populations of specific interest.

      Abstract: Objective To report long‐term outcomes of laparoscopic radical cystectomy (LRC) in a multi‐centric European cohort, and explore feasibility and safety of the procedure. Patients and Methods This study was coordinated by EAU‐section of Uro‐technology (ESUT) with nine centers enrolling 503 patients undergoing LRC for bladder cancer prospectively between 2000 and 2013. Data were retrospectively analyzed. Descriptive statistics were used to explore peri‐ and post‐operative characteristics of the cohort. Kaplan‐Meier curves were constructed to evaluate recurrence free survival (RFS), cancer specific survival (CSS) and overall survival (OS). Outcomes were also stratified according to tumour stage, node involvement and surgical margin status. Results Minor complications (Clavien I‐II) occurred in 39% and major (IIIa‐IVb) in 17%. 10 (2%) post‐operative deaths were recorded. Median lymph node retrieval was 14 (IQR 9‐17) and positive surgical margins were detected in 29 (5.8%) patients. Median follow‐up was 50 months (mean 60, IQR 19‐90), during which 134 (27%) recurrences were detected. Actuarial RFS, CSS and OS rates were 66%, 75% and 62% at 5years and 62%, 55%, 38% at 10 years. Significant differences in RFS, CSS and OS were found according to tumour stage, node involvement and margin status (log‐rank p

  • The impact of robotic surgery on the surgical management of prostate
           cancer in the USA
    • Authors: Steven L. Chang; Adam S. Kibel, James D. Brooks, Benjamin I. Chung
      Abstract: Objective To describe the surgeon characteristics associated with robot‐assisted radical prostatectomy (RARP) adoption and determine the possible impact of this adoption on practice patterns and cost. Patients and Methods A retrospective cohort study with a weighted sample size of 489 369 men who underwent non‐RARP (i.e., open or laparoscopic RP) or RARP in the USA from 2003 to 2010 was performed. We evaluated predictors for RARP adoption, defined as performing >50% of annual RP using the robotic approach. Additionally, we identified the resulting changes in prostate cancer surgery practice patterns and expenditures. Results From 2003 to 2010, RARP adoption increased from 0.7% to 42% of surgeons performing RP. High‐volume surgeons, defined as performing >24 RPs annually, had statically significantly higher odds of adopting RARP throughout the study period. From 2005 to 2007, adoption was more common among surgeons at teaching (odds ratio [OR] 2.4, 95% confidence interval [CI] 1.7–3.4), intermediate‐ (200–399 beds; OR 5.96, 95% CI 1.3–26.5) and large‐sized hospitals (≥400 beds; OR 6.1, 95% CI 1.4–25.8); after 2007, adoption was more common among surgeons at urban hospitals (OR 3.3, 95% CI 1.7–6.4). RARP adoption was generally associated with increased RP volume, greatest for high‐volume surgeons and least for low‐volume surgeons (

  • Preventable mortality after common urological surgery: failing to
           rescue'

      Abstract: Objective To assess in‐hospital mortality in patients undergoing many commonly performed urological surgeries in light of decreasing nationwide perioperative mortality over the past decade. This phenomenon has been attributed in part to a decline in ‘failure to rescue’ (FTR) rates, e.g. death after a complication that was potentially recognisable/preventable. Patients and Methods Discharges of all patients undergoing urological surgery between 1998 and 2010 were extracted from the Nationwide Inpatient Sample and assessed for overall and FTR mortality. Admission trends were assessed with linear regression. Logistic regression models fitted with generalised estimating equations were used to estimate the impact of primary predictors on over‐all and FTR mortality and changes in mortality rates. Results Between 1998 and 2010, an estimated 7 725 736 urological surgeries requiring hospitalisation were performed in the USA; admissions for urological surgery decreased 0.63% per year (P = 0.008). Odds of overall mortality decreased slightly (odds ratio [OR] 0.990, 95% confidence interval [CI] 0.988–0.993), yet the odds of mortality attributable to FTR increased 5% every year (OR 1.050, 95% CI 1.038–1.062). Patient age, race, Charlson Comorbidity Index, public insurance status, as well as urban hospital location were independent predictors of FTR mortality (P < 0.001). Conclusion A shift from inpatient to outpatient surgery for commonly performed urological procedures has coincided with increasing rates of FTR mortality. Older, sicker, minority group patients and those with public insurance were more likely to die after a potentially recognisable/preventable complication. These strata of high‐risk individuals represent ideal targets for process improvement initiatives.

    • Authors: Eric S. Wisenbaugh; Mark D. Tyson, Erik P. Castle, Mitchell R. Humphreys, Paul E. Andrews
      Abstract: Objective To determine if massive renal size should be a contraindication for attempting a laparoscopic approach to bilateral native nephrectomies in patients with autosomal dominant polycystic kidney disease (ADPKD). Patients and Methods We retrospectively reviewed all laparoscopic bilateral nephrectomies performed for ADPKD at our institution from 1 January 2000 to 31 December 2012. We stratified patients by kidney weight (with or without at least one kidney weighing >2500 g) and compared perioperative data, complications, and status of kidney allografts. Additionally, the subset of patients with at least one kidney weighing >3500 g was compared with the rest of the cohort. Results We identified 68 patients; mean (range) individual kidney weight was 1984 (197–5042) g. In all, 24 patients had at least one kidney weighing >2500 g, yet patients in this group were not significantly different from the rest of the cohort for complications, estimated blood loss, transfusion rate, or duration of hospitalisation. For those who underwent simultaneous renal allotransplantation, native kidney size was not associated with graft outcomes. Additionally, of the six patients with at least one kidney weighing >3500 g, only one required a blood transfusion, and the group had no intraoperative or postoperative Clavien grade ≥3 complications. None of the cohort required conversion to open surgery. Conclusion Massive size of polycystic kidneys is not a contraindication to attempting a laparoscopic approach to bilateral nephrectomies in an experienced, high‐volume centre.

           single‐site inguinal lymphadenectomy: comparison with the
           conventional laparoscopic technique
    • Authors: Jun‐Bin Yuan; Min‐Feng Chen, Lin Qi, Yuan Li, Yang‐Le Li, Cheng Chen, Jin‐bo Chen, Xiong‐Bing Zu, Long‐Fei Liu
      Abstract: Objective To prospectively study the surgical strategies and clinical efficacy of laparoendoscopic single‐site (LESS) inguinal lymphadenectomy compared with conventional endoscopic inguinal lymphadenectomy for the management of inguinal nodes. Patients and Methods A total of 12 patients with squamous cell carcinoma of the penis who underwent penectomy between February and July 2013 were enrolled in the study. All 12 patients underwent bilateral inguinal lymphadenectomy (LESS inguinal lymphadenectomy in one limb and conventional endoscopic inguinal lymphadenectomy in the other) with preservation of the saphenous vein. All lymphatic tissue in the boundaries of the adductor longus muscle (medially), the sartorius muscle (laterally), 2 cm above the inguinal ligament (superiorly), the Scarpa fascia (superficially) and femoral vessels (deeply) was removed in both surgical techniques. All 24 procedures were performed by one experienced surgeon. Results All 24 procedures (12 LESS and 12 conventional endoscopic inguinal lymphadenectomies) were completed successfully without conversion to open surgery. For LESS inguinal lymphadenectomy and conventional endoscopic inguinal lymphadenectomy groups, the mean ± sd operating time was 94.6 ± 14.8 min and 90.8 ± 10.6 min, respectively (P = 0.145). No significant differences in the incidence of postoperative complications (skin‐related problems, hecatomb, lower extremity oedema, lymphatic complications and overall complications) were noted between the two groups (P > 0.05). No lower extremity oedema occurred in any limbs of the two groups. No significant differences were observed in either lymph node clearance rate or detection rate of histologically positive lymph nodes (P > 0.05). The patient satisfaction rate with scar appearance and cosmetic results was significantly better in the LESS inguinal lymphadenectomy group than in the conventional endoscopic inguinal lymphadenectomy group of (75 vs 25%; P = 0.039). Conclusions This preliminary study suggests that both LESS inguinal lymphadenectomy and conventional endoscopic inguinal lymphadenectomy are safe and feasible procedures for inguinal lymphadenectomy. Preservation of the saphenous vein during LESS inguinal lymphadenectomy/conventional endoscopic inguinal lymphadenectomy can effectively reduce the incidence of postoperative lower extremity oedema. LESS inguinal lymphadenectomy seems to provide better cosmetic results than conventional endoscopic inguinal lymphadenectomy.

  • Repeated biopsies in patients with prostate cancer on active surveillance:
           clinical implications of interobserver variation in histopathological
           assessment
    • Authors: Frederik B. Thomsen; Niels Marcussen, Kasper D. Berg, Ib J. Christensen, Ben Vainer, Peter Iversen, Klaus Brasso
      Abstract: Objective To investigate the clinical implications of interobserver variation in the assessment of re‐biopsies obtained during active surveillance (AS) of prostate cancer. Patients and Methods In all, 107 patients with low‐risk prostate cancer with 93 diagnostic biopsy sets and 109 re‐biopsy sets were included. The International Society of Urological Pathology 2005 Gleason scoring system was used for the histopathological assessment of all biopsies. Three different definitions of histopathological progression were applied. Unweighted and linear weighted Kappa (κ) statistics were used to compare the interobserver agreement. Results The overall Gleason score agreement was 68.8% with a weighted κ of 0.670. The interobserver agreement was 79.6% for meeting the AS selection criteria. According to the three progression definitions applied, overall agreement was between 80.7% and 89.0% with weighted κ values of 0.746–0.791. Treatment recommendations would have changed in up to 10.1% (95% confidence interval 5.4–17.7%) of the 109 re‐biopsy sets. Conclusion Kappa statistics showed strong agreement between the histological evaluations. However, up to 10% of patients on AS would receive a different treatment recommendation depending upon which histopathological evaluation of re‐biopsies was used for treatment planning.

  • Association of Androgen Deprivation Therapy with Excess
           Cardiac‐Specific Mortality in Men with Prostate Cancer

      Abstract: Objectives To determine if androgen deprivation therapy (ADT) is associated with excess cardiac‐specific mortality (CSM) in men with prostate cancer and no cardiovascular comorbidity, coronary artery disease risk factors, or congestive heart failure (CHF) or past myocardial infarction (MI). Subjects/patients and methods Five thousand seventy‐seven men (median age, 69.5 years) with cT1c‐T3N0M0 prostate cancer were treated with brachytherapy with or without neoadjuvant ADT (median duration, four months) between 1997 and 2006. Fine and Gray's competing risks analysis evaluated the association of ADT with CSM, adjusting for age, year of brachytherapy, and ADT treatment propensity score among men in groups defined by cardiac comorbidity. Results After a median follow‐up of 4.8 years, no association was detected between ADT and CSM in men with no cardiac risk factors (1.08% at 5 years for ADT vs 1.27% at five years for no ADT, adjusted hazard ratio (AHR) 0.83; 95% confidence interval (CI), 0.39‐1.78; P=0.64; n=2653) or in men with diabetes mellitus, hypertension, or hypercholesterolemia (2.09% vs 1.97%, AHR, 1.33; 95% CI, 0.70‐2.53; P=0.39; n=2168). However, ADT was associated with significantly increased CSM in men with CHF or MI (AHR 3.28; 95% CI 1.01‐10.64; P=0.048; n=256). In this subgroup, the five‐year cumulative incidence of CSM was 7.01% (95% CI 2.82‐13.82%) for ADT vs 2.01% (95% CI 0.38‐6.45%) for no ADT. Conclusion ADT was associated with a five percent absolute excess risk of CSM at five years in men with CHF or prior MI, suggesting that administering ADT to 20 men in this potentially vulnerable subgroup could result in one cardiac death.

  • Exploring associations between LUTS and GI problems in women: a study in
           women with urological and GI problems versus a control population
    • Authors: M. Wyndaele; B.Y. De Winter, P.A. Pelckmans, S. De Wachter, M. Van Outryve, J.J. Wyndaele
      Abstract: Objectives First, to study the prevalence of self‐reported LUTS in women consulting a Gastroenterology clinic with complaints of functional constipation (FC), fecal incontinence (FI) or both, compared to a female control population. Secondly, to study the influence of FC, FI, or both on self‐reported LUTS in women attending a Urology clinic. Patients and methods We present a retrospective study of data collected through a validated self‐administered bladder and bowel symptom questionnaire in a tertiary referral hospital from three different female populations: 104 controls, 159 gastroenterological patients and 410 urological patients. Based on the reported bowel symptoms, patients were classified as having FC, FI, a combination of both, or, no FC or FI. LUTS were compared between the control population and the gastroenterological patients, and between urological patients with and without concomitant gastroenterological complaints. Results were corrected for possible confounders through logistic regression analysis. Results The prevalence of LUTS in the control population was comparable to large population‐based studies. Nocturia was significantly more prevalent in gastroenterological patients with FI compared to the control population (OR 9.1). Female gastroenterological patients with FC more often reported straining to void (OR 10.3), intermittency (OR 5.5), need to immediately revoid (OR 3.7) and feeling of incomplete emptying (OR 10.5) compared to the control population. In urological patients, urgency (94%) and UUI (54% of UI) were reported more often by patients with FI than by patients without gastroenterological complaints (58% and 30% of UI respectively), whereas intermittency (OR 3.6), need to immediately revoid (OR 2.2) and feeling of incomplete emptying (OR 2.2) were reported more often by patients with FC than by patients without gastroenterological complaints. Conclusion As LUTS are reported significantly more often by female gastroenterological patients than by a control population, and as there is a difference in self‐reported LUTS between female urological patients with different concomitant gastroenterological complaints, we suggest that general practitioners, gastroenterologists and urologists should always include the assessment of symptoms of the other pelvic organ system in their patient evaluation. The clinical correlations between bowel and LUT symptoms may be explained by underlying neurological mechanisms.

  • Is radical nephrectomy a legitimate therapeutic option in patients with
           renal masses amenable to nephron‐sparing surgery'
    • Authors: Jeffrey J. Tomaszewski; Marc C. Smaldone, Robert G. Uzzo, Alexander Kutikov
      First page: 357
      Abstract: The decision to perform a radical nephrectomy (RN) or a partial nephrectomy (PN), not unlike most decisions in clinical practice, ultimately hinges on the balance of risk. Do the higher risks of a more complex surgery (PN) justify the theoretical benefits of kidney tissue preservation' Data suggest that for patients with an anatomically complex renal mass and a normal contralateral kidney, for whom additional surgical intensity may be risky, such as the elderly and comorbid, RN presents a robust treatment option. Nevertheless, PN, especially for small and anatomically simple renal masses in young patients without comorbidities should remain the surgical reference standard, as preservation of renal tissue can serve as an ‘insurance policy’ not only against future renal functional decline, but also against the possibility of tumour development in the contralateral kidney. In the present review, we outline the ongoing debate between the role of RN and PN in treatment of the enhancing renal mass.

  • Implementing newer agents for the management of castrate‐resistant
           prostate cancer: what is known and what is needed'
    • Authors: Nicolas Mottet; Noel Clarke, Maria De Santis, Filiberto Zattoni, Juan Morote, Steven Joniau
      First page: 364
      Abstract: Men receiving androgen‐deprivation therapy will in time develop metastatic castrate‐resistant prostate cancer (mCRPC). Whilst effective treatment options for mCRPC have traditionally been limited, new agents are becoming available. Since 2010, the number and class of agents available to treat mCRPC has increased dramatically. As such, there is a need for clear guidance on the optimum treatment and sequence of treatments for mCRPC before and after chemotherapy. This evidence‐based statement, reflecting the views of the authors, provides suggestions on the continued relevance of conventional approaches to first‐ and second‐line treatment in mCRPC, the potential role of novel treatments, and factors that may influence the choice of hormonal agents and/or chemotherapy.

      First page: 373
      Abstract: Objective To examine prostate‐specific antigen (PSA) levels after enzalutamide discontinuation to assess whether an antiandrogen withdrawal syndrome (AAWS) exists with enzalutamide. Methods We retrospectively identified 30 consecutive patients with metastatic prostate cancer who were treated with enzalutamide after docetaxel. Post‐discontinuation PSA results were available for all patients and were determined at 2‐weekly intervals until starting further anticancer systemic therapy. PSA withdrawal response was defined as a PSA decline by ≥50% from the last on‐treatment PSA, with a confirmed decrease ≥3 weeks later. Patient characteristics were evaluated in relation to the AAWS using univariate logistic regression analysis. Results The median (range) patient age was 70.5 (56–86) years and the median (range) follow‐up was 9.0 (0.5–16) months. The most common metastatic sites were the bone (86.7%) and lymph nodes (66.7%). Most patients (70%) had previously received abiraterone and 12 patients (40%) had also received cabazitaxel. The median (range) treatment duration with enzalutamide was 3.68 (1.12–21.39) months. PSA levels after enzalutamide withdrawal were monitored for a median (range) time of 35 (10–120) days. Only one patient (3.3%) had a confirmed PSA response ≥50% after enzalutamide discontinuation. One patient (3.3%) had a confirmed PSA response of between 30 and 50% and another patient (3.3%) had an unconfirmed PSA response of between 30 and 50%. The median overall survival was 15.5 months (95% CI 8.1–24.7). None of the factors analysed in the univariate analysis were significant predictors of PSA decline after enzalutamide discontinuation. Conclusions This retrospective study provides the first evidence that enzalutamide may have an AAWS in a minority of patients with metastatic castration‐resistant prostate cancer. Further studies are needed to confirm the existence of an enzalutamide AAWS and to assess its relevance in prostate cancer management.

      Abstract: Objectives To determine the diagnostic yield of analysing biparametric (T2‐ and diffusion‐weighted) magnetic resonance imaging (B‐MRI) for prostate cancer detection compared with standard digital rectal examination (DRE) and prostate‐specific antigen (PSA)‐based screening. Patients and Methods Review of patients who were enrolled in a trial to undergo multiparametric‐prostate (MP)‐MRI and MR/ultrasound fusion‐guided prostate biopsy at our institution identified 143 men who underwent MP‐MRI in addition to standard DRE and PSA‐based prostate cancer screening before any prostate biopsy. Patient demographics, DRE staging, PSA level, PSA density (PSAD), and B‐MRI findings were assessed for association with prostate cancer detection on biopsy. Results Men with detected prostate cancer tended to be older, with a higher PSA level, higher PSAD, and more screen‐positive lesions (SPL) on B‐MRI. B‐MRI performed well for the detection of prostate cancer with an area under the curve (AUC) of 0.80 (compared with 0.66 and 0.74 for PSA level and PSAD, respectively). We derived combined PSA and MRI‐based formulas for detection of prostate cancer with optimised thresholds. (i) for PSA and B‐MRI: PSA level + 6 x (the number of SPL) > 14 and (ii) for PSAD and B‐MRI: 14 × (PSAD) + (the number of SPL) >4.25. AUC for equations 1 and 2 were 0.83 and 0.87 and overall accuracy of prostate cancer detection was 79% in both models. Conclusions The number of lesions positive on B‐MRI outperforms PSA alone in detection of prostate cancer. Furthermore, this imaging criteria coupled as an adjunct with PSA level and PSAD, provides even more accuracy in detecting clinically significant prostate cancer.

      First page: 389
      Abstract: Objectives To characterise and measure different components of preoperative delays experienced by patients with bladder cancer before radical cystectomy (RC) in the province of Quebec, Canada and to identify the predictors of long waiting times. Methods We conducted a retrospective cohort study using the data of patients who underwent RC for bladder cancer between 2000 and 2009 in Quebec. The cohort was obtained with the linkage of two provincial health databases: the Régie de l'assurance maladie du Québec database (data on medical services dispensed to Quebec residents), and the Fichier des évenements démographiques de l’Institut de la statistique du Québec database (demographic data on births and deaths). For the entire cohort, we determined several components of delay from first medical visit related to bladder cancer symptoms until RC. Predictors of long delays were analysed using logistic regression. Results We analysed a total of 2778 patients who met the inclusion criteria. The median urologist referral delay was 32 days. The median delays between first urologist visit and RC and between transurethral resection of bladder tumour (TURBT) to RC were 90 days and 46 days, respectively. The median overall delay was 116 days. All components of delay progressively increased from the decade of the 1990s to the decade of the 2000s. Male gender was a protective factor for several components of delay, which suggests that gender‐related variations may exist in the course of care for bladder cancer (odds ratio 0.67, 95% CI 0.50–0.89 for overall delay). Patient age and gender were associated with delayed urologist referral, delayed time to TURBT, and long overall waiting time. Factors related to the health system were associated with long cystoscopy delays. Conclusion Median preoperative delays among patients with bladder cancer have been increasing and remain unacceptably long. Patient's age, gender and type of hospital facility were associated with long waiting times.

      First page: 397
      Abstract: Objective To assess the prognostic role of preoperative serum cholesterol in patients with renal cell carcinoma (RCC), as increasing evidence suggests that alterations in the lipid profile are associated with the development, progression and prognosis of various cancers. Patients and Methods We analysed 867 patients, who underwent radical or partial nephrectomy for RCC between 2002 and 2012. Preoperative total cholesterol levels were determined in serum using colorimetric analysis (CHOD‐PAP method). The association with cancer‐specific survival (CSS) was assessed with Cox models. Discrimination was quantified with the C‐index. The median follow‐up was 52 months. Results The median (interquartile range) serum cholesterol was 195 (166–232) mg/dL. Decreasing serum cholesterol was associated with more advanced T, N and M stages (P < 0.001), higher grades (P = 0.001) and presence of tumour necrosis (P = 0.002). Continuously coded cholesterol was associated with CSS in both univariable (hazard ratio [HR] 0.87, P < 0.001) and multivariable analyses (HR 0.93, P = 0.001). The discrimination of a multivariable base model increased significantly from 88.3% to 89.2% following inclusion of cholesterol (P = 0.006). In patients with clinically localised disease (T1–3N0/+M0), cholesterol remained associated with CSS in multivariable analysis (HR 0.90, P = 0.002) and increased the discrimination from 74.6% to 76.9% (P = 0.002). Conclusions Preoperative serum cholesterol is an independent prognostic factor for patients with RCC, with lower levels being associated with worse survival. Its use increases the discrimination of established prognostic factors. As cholesterol is a broadly available routine marker, its use may provide a meaningful adjunct in clinical practice. The biological rationale underlying this association remains to be clarified.

      Abstract: Objective To demonstrate sarcomatoid differentiation is an independent prognostic feature for patients with grade 4 renal cell carcinoma (RCC) with or without distant metastases. To identify independent predictors of survival, evaluate the correlation between the amount of sarcomatoid differentiation and cancer‐specific survival (CSS), and to design a multivariate prognostic model for patients with sarcomatoid RCC. Patients and Methods We used the Mayo Clinic Nephrectomy Registry to identify 204 post‐nephrectomy patients with sarcomatoid‐variant RCC, as well as 207 patients with unilateral grade 4 RCC without sarcomatoid features for comparison. All slides were reviewed by one pathologist. CSS was estimated using the Kaplan–Meier method. The associations of clinical and pathological features with death from RCC were evaluated using Cox proportional hazards regression models. Results For all patients with grade 4 RCC, the presence of sarcomatoid differentiation was associated with a 58% increased risk of death from RCC (P < 0.001). For patients with grade 4 non‐metastatic (M0) RCC, the presence of sarcomatoid differentiation was associated with an 82% increased risk of death from RCC (P < 0.001). For patients with sarcomatoid RCC, the 2009 primary tumour classifications, presence of regional lymph nodes and distant metastases, coagulative tumour necrosis, and the amount of sarcomatoid differentiation were each significantly associated with death from RCC in a multivariate setting. After adjusting for other prognostic variables, each 10% increase in the amount of sarcomatoid differentiation was associated with a 6% increased risk of death from RCC (P = 0.028). Patients whose tumours contained ≥30% (median amount) sarcomatoid differentiation were 52% more likely to die from RCC compared with patients whose tumours contained

      Abstract: Objective To investigate the diagnostic performance and safety of a three‐dimensional 14‐core biopsy (3D14PBx) method, which is a combination of the transrectal six‐core and transperineal eight‐core biopsy methods. Patients and Methods Between December 2005 and August 2010, 1103 men underwent 3D14PBx at our institutions and were analysed prospectively. Biopsy criteria included a PSA level of 2.5–20 ng/mL or abnormal digital rectal examination (DRE) findings, or both. The primary endpoint of the study was diagnostic performance and the secondary endpoint was safety. We applied recursive partitioning to the entire study cohort to delineate the unique contribution of each sampling site to overall and clinically significant cancer detection. Results Prostate cancer was detected in 503 of the 1103 patients (45.6%). Age, family history of prostate cancer, DRE, PSA, percentage of free PSA and prostate volume were associated with the positive biopsy results significantly and independently. Of the 503 cancers detected, 39 (7.8%) were clinically locally advanced (≥cT3a), 348 (69%) had a biopsy Gleason score (GS) of ≥7, and 463 (92%) met the definition of biopsy‐based significant cancer. Recursive partitioning analysis showed that each sampling site contributed uniquely to both the overall and the biopsy‐based significant cancer detection rate of the 3D14PBx method. The overall cancer‐positive rate of each sampling site ranged from 14.5% in the transrectal far lateral base to 22.8% in the transrectal far lateral apex. As of August 2010, 210 patients (42%) had undergone radical prostatectomy, of whom 55 (26%) were found to have pathologically non‐organ‐confined disease, 174 (83%) had prostatectomy GS ≥7 and 185 (88%) met the definition of prostatectomy‐based significant cancer. Conclusions This is the first prospective analysis of the diagnostic performance of an extended biopsy method, which is a simplified version of the somewhat redundant super‐extended three‐dimensional 26‐core biopsy. As expected, each sampling site uniquely contributed not only to overall cancer detection, but also to significant cancer detection. 3D14PBx is a feasible systematic biopsy method in men with PSA

      Abstract: Objectives To evaluate the impact of a genomic classifier (GC) test for predicting metastasis risk after radical prostatectomy (RP) on urologists' decision‐making about adjuvant treatment of patients with high‐risk prostate cancer. Subjects and Methods Patient case history was extracted from the medical records of each of the 145 patients with pT3 disease or positive surgical margins (PSMs) after RP treated by six high‐volume urologists, from five community practices. GC results were available for 122 (84%) of these patients. US board‐certified urologists (n = 107) were invited to provide adjuvant treatment recommendations for 10 cases randomly drawn from the pool of patient case histories. For each case, the study participants were asked to make an adjuvant therapy recommendation without (clinical variables only) and with knowledge of the GC test results. Recommendations were made without knowledge of other participants' responses and the presentation of case histories was randomised to minimise recall bias. Results A total of 110 patient case histories were available for review by the study participants. The median patient age was 62 years, 71% of patients had pT3 disease and 63% had PSMs. The median (range) 5‐year predicted probability of metastasis by the GC test for the cohort was 3.9 (1–33)% and the GC test classified 72% of patients as having low risk for metastasis. A total of 51 urologists consented to the study and provided 530 adjuvant treatment recommendations without, and 530 with knowledge of the GC test results. Study participants performed a mean of 130 RPs/year and 55% were from community‐based practices. Without GC test result knowledge, observation was recommended for 57% (n = 303), adjuvant radiation therapy (ART) for 36% (n = 193) and other treatments for 7% (n = 34) of patients. Overall, 31% (95% CI: 27–35%) of treatment recommendations changed with knowledge of the GC test results. Of the ART recommendations without GC test result knowledge, 40% (n = 77) changed to observation (95% CI: 33–47%) with this knowledge. Of patients recommended for observation, 13% (n = 38 [95% CI: 9–17%]) were changed to ART with knowledge of the GC test result. Patients with low risk disease according to the GC test were recommended for observation 81% of the time (n = 276), while of those with high risk, 65% were recommended for treatment (n = 118; P < 0.001). Treatment intensity was strongly correlated with the GC‐predicted probability of metastasis (P < 0.001) and the GC test was the dominant risk factor driving decisions in multivariable analysis (odds ratio 8.6, 95% CI: 5.3–14.3%; P < 0.001). Conclusions Knowledge of GC test results had a direct effect on treatment strategies after surgery. Recommendations for observation increased by 20% for patients assessed by the GC test to be at low risk of metastasis, whereas recommendations for treatment increased by 16% for patients at high risk of metastasis. These results suggest that the implementation of genomic testing in clinical practice may lead to significant changes in adjuvant therapy decision‐making for high‐risk prostate cancer.

      Abstract: Objective To evaluate the utility of robotic repair of injuries to the ureter or bladder from obstetrical and gynaecological (OBGYN) surgery Patients and Methods A retrospective review of all patients from four different high‐volume institutions between 2002 and 2013 that had a robot‐assisted (RA) repair by a urologist after an OBGYN genitourinary injury. Results Of the 43 OBGYN operations, 34 were hysterectomies: 10 open, 10 RA, nine vaginally, and five pure laparoscopic. Nine patients had alternative OBGYN operations: three caesarean sections, three oophorectomies (one open, two laparoscopic), one RA colpopexy, one open pelvic cervical cerclage with mesh and one RA removal of an invasive endometrioma. In all, 49 genitourinary (GU) injuries were sustained: ureteric ligation (26), ureterovaginal fistula (10), ureterocutaneous fistula (one), vesicovaginal fistula (VVF; 10) and cystotomy alone (two). In all, 10 patients (23.3%) underwent immediate urological repair at the time of their OBGYN RA surgery. The mean (range) time between OBGYN injury and definitive delayed repair was 23.5 (1–297) months. Four patients had undergone prior failed repair: two open VVF repairs and two balloon ureteric dilatations with stent placement. In all, 22 ureteric re‐implants (11 with ipsilateral psoas hitch) and 15 uretero‐ureterostomies were performed. Stents were placed in all ureteric cases for a mean (range) of 32 (1–63) days. In all, 10 VVF repairs and two primary cystotomy closures were performed. Drains were placed in 28 cases (57.1%) for a mean (range) of 4.1 (1–26) days. No case required open conversion. Two patients (4.1%) developed ureteric obstruction after RA repair requiring dilatation and stenting. The mean (range) follow‐up of the entire cohort was 16.6 (1–63) months. Conclusions RA repair of GU injuries during OBGYN surgery is associated with good outcomes, appears safe and feasible, and can be used successfully immediately after injury recognition or as a salvage procedure after prior attempted repair. RA techniques may improve convalescence in a patient population where quick recovery is paramount.

      Abstract: Objectives To compare the peri‐operative and early renal functional outcomes of robot‐assisted partial nephrectomy (RAPN) and laparoscopic partial nephrectomy (LPN) for kidney tumours. Materials and Methods A total of 237 patients fulfilling the selection criteria were included, of whom 146 and 91 patients were treated with LPN and RAPN, respectively. To adjust for potential baseline confounders, propensity‐score matching was performed. A favourable outcome was defined as a warm ischaemia time (WIT) of ≤20 min, negative surgical margins, no surgical conversion, no Clavien ≥3 complications and no postoperative chronic kidney disease (CKD) upstaging. Descriptive statistics and multivariable logistic regression analyses were performed before and after propensity‐score matching. Results Within the propensity‐score‐matched cohort, the RAPN group was associated with significantly lower estimated blood loss (EBL; 156 vs 198 mL, mean difference [MD] = −42; P = 0.025), a shorter WIT (22.8 vs 31 min, MD = −8.2; P < 0.001) and a higher proportion of malignant lesions (88.4 vs 67.5%; odds ratio [OR]: 2.6; 95% confidence interval [CI]: 1.2–5.67; P = 0.023). With regard to early renal functional outcomes, the mean last estimated glomerular filtration rate was 95.8 and 89.4 mL/min per 1.73 m2 (MD = 6.4; P = 0.01), with a mean ± sd percentage change of −4.8 ± 17.9 and −12.2 ± 16.6 (MD = 7.4; P = 0.018) in the RAPN and LPN groups, respectively. The intra‐operative complication rate was significantly lower in the RAPN group (1.3 vs 11.7%; OR 0.1, 95% CI 0.01–0.81; P = 0.018). On multivariable analysis, surgical approach (RAPN vs LPN, OR 5.457, 95% CI 2.075–14.346; P = 0.001), Charlson Comorbidity Index (OR 0.223; 95% CI 0.062–0.811; P = 0.023), diameter‐axial‐polar score (OR 0.488, 95% CI 0.329–0.723; P < 0.001) and preoperative CKD stage (OR 3.189, 95% CI 1.204–8.446; P = 0.020) were found to be independent predictors of obtaining a favourable outcome. Conclusions After adjusting for potential treatment selection biases, RAPN was found to be superior to LPN for peri‐operative outcomes (EBL, WIT and intra‐operative complications) and early renal functional preservation.

      Abstract: Objective To develop and internally validate a preoperative nomogram for predicting stone‐free status (SF) after flexible ureteroscopy (fURS) for renal stones, as there is a need to predict the outcome of fURS for the treatment of renal stone disease. Patients and Methods We retrospectively analysed 310 fURS procedures for renal stone removal performed between December 2009 and April 2013. Final outcome of fURS was determined by computed tomography 3 months after the last fURS session. Assessed preoperative factors included stone volume and number, age, sex, presence of hydronephrosis and lower pole calculi, and ureteric stent placement. Multivariate logistic regression analysis with backward selection was used to model the relationship between preoperative factors and SF after fURS. Bootstrapping was used to internally validate the nomogram. Results Five independent predictors of SF after fURS were identified: stone volume (P < 0.001), presence of lower pole calculi (P = 0.001), operator with experience of >50 fURS (P = 0.026), stone number (P = 0.075), and presence of hydronephrosis (P = 0.047). We developed a nomogram to predict SF after fURS using these five preoperative characteristics. Total nomogram score (maximum 25) was derived from summing individual scores of each predictive variable; a high total score was predictive of successful fURS outcome, whereas a low total score was predictive of unsuccessful outcome. The area under the receiver operating characteristics for nomogram predictions was 0.87. Conclusion The nomogram can be used to reliably predict SF based on patient characteristics after fURS treatment of renal stone disease.

      Abstract: Objective To assess the long‐term efficacy of polydimethylsiloxane (Macroplastique®) injection (MPI) in the treatment of Mitrofanoff leakage secondary to valve incompetence. Patients and Methods Between 1995 and 2012, the records of 24 consecutive patients who underwent MPI for Mitrofanoff urinary leakage after continent cutaneous urinary diversion (CCUD) surgery were examined. All patients had a valve deemed of sufficient length (>2 cm) to attempt Macroplastique coaptation. Treatment outcomes were divided into three categories based on physician assessment: success (dry), partial success (>50% reduction in incontinence pads) and failure. Success rates were assessed according to the type of reservoir and conduit channel. Results The mean (range) follow‐up was 30 (6–96) months. One patient had initial difficulty catheterising, and subsequently required major revision surgery. In all, 12 patients (50%) failed the treatment and subsequently underwent operative revision to the channel. Three patients (12.5%) achieved complete success; one patient had an appendix channel through native bladder and the remaining two had Monti channels through colon. Nine patients (37.5%) had partial success; success rates were higher with appendix channels (four of six) and colonic reservoirs (six of seven) when compared with Monti channels (eight of 18, 44%) and ileal reservoirs (zero of two). Five of the nine patients with partial success eventually required further surgical revision for deteriorating continence at a mean (range) of 41 (14–96) months, whilst the other four have maintained sufficient continence with MPI alone. Conclusion Macroplastique bulking cured only 12.5% patients, but leakage was substantially improved in a further 37.5% allowing major surgery to be avoided or postponed in one half of the cohort. Appendix Mitrofanoffs do better than the Monti Mitrofanoff, with channels through colonic segments generally doing better than those through ileal bladders. MPI should be considered as a less invasive alternative to avoid or delay major reconstructive surgery.

      Abstract: OBJECTIVE To evaluate the effects of bariatric surgery on Lower Urinary Tract Symptoms in a prospective cohort study. MATERIALS AND METHODS Patients undergoing bariatric surgery were recruited into the study. Assessment was done using International Prostate Symptoms Score (IPSS) in men and Bristol Female Lower Urinary Tract Symptoms Score Questionnaire (BFLUTS) in women. Serum glucose, insulin and PSA levels were recorded, insulin resistance was quantified using Homeostasis Model Assessment method (HOMA‐IR). Patients were assessed prior to; 6‐8 weeks post; and 1 year post surgery. Weight loss, change in BMI, total symptoms score as well as individual symptoms were tested for statistical significance with correction for multiple testing using Bonferroni method. Linear regression analysis was performed with total symptoms score change at one year as the outcome variable and BMI, age, total symptoms score before surgery, HOMA‐IR, glucose level before surgery, insulin level before surgery, change in insulin level after surgery, weight loss and BMI loss as predictor variables. RESULTS 86 patients were recruited, 82% completed at least one follow up after surgery. There was significant weight loss and reduction of BMI after surgery (p

      Abstract: Objectives To compare percutaneous nephrostomy (PCN) tube vs JJ ureteric stenting as the initial urinary drainage method in children with obstructive calcular anuria (OCA) and post‐renal acute renal failure (ARF) due to bilateral ureteric calculi, to identify the selection criteria for the initial urinary drainage method that will improve urinary drainage, decrease complications and facilitate the subsequent definitive clearance of stones, as this comparison is lacking in the literature. Patients and Methods A series of 90 children aged ≤12 years presenting with OCA and ARF due to bilateral ureteric calculi were included from March 2011 to September 2013 at Cairo University Pediatric Hospital in this randomised comparative study. Patients with grade 0–1 hydronephrosis, fever or pyonephrosis were excluded. No patient had any contraindication for either method of drainage. Stable patients (or patients stabilised by dialysis) were randomised (non‐blinded, block randomisation, sealed envelope method) into PCN‐tube or bilateral JJ‐stent groups (45 patients for each group). Initial urinary drainage was performed under general anaesthesia and fluoroscopic guidance. We used 4.8–6 F JJ stents or 6–8 F PCN tubes. The primary outcomes were the safety and efficacy of both groups for the recovery of renal functions. Both groups were compared for operative and imaging times, complications, and the period required for a return to normal serum creatinine levels. The secondary outcomes included the number of subsequent interventions needed for clearance of stones. Additional analysis was done for factors affecting outcome within each group. Results All presented patients completed the study with intention‐to‐treat analysis. There was no significant difference between the PCN‐tube and JJ‐stent groups for the operative and imaging times, period for return to a normal creatinine level and failure of insertion. There were significantly more complications in the PCN‐tube group. The stone size (>2 cm) was the only factor affecting the rates of mucosal complications, operative time and failure of insertion in the JJ‐stent group. The degree of hydronephrosis significantly affected the operative time for PCN‐tube insertion. Grade 2 hydronephrosis was associated with all cases of insertion failure in the PCN‐tube group. The total number of subsequent interventions needed to clear stones was significantly higher in the PCN‐tube group, especially in patients with bilateral stones destined for chemolytic dissolution (alkalinisation) or extracorporeal shockwave lithotripsy (ESWL). Conclusion We recommend the use of JJ stents for initial urinary drainage for stones that will be subsequently treated with chemolytic dissolution or ESWL, as this will lower the total number of subsequent interventions needed to clear the stones. This is also true for stones destined for ureteroscopy (URS), as JJ‐stent insertion will facilitate subsequent URS due to previous ureteric stenting. Mild hydronephrosis will prolong the operative time for PCN‐tube insertion and may increase the incidence of insertion failure. We recommend the use of PCN tube if the stone size is >2 cm, as there was a greater risk of possible iatrogenic ureteric injury during stenting with these larger ureteric stones in addition to prolongation of operative time with an increased incidence of failure.

      First page: 486
      Abstract: Objective To assess the emerging use of Twitter by urological journals. Methods A search of the Journal of Citation Reports 2012 was performed to identify urological journals. These journals were then searched on Twitter.com. Each journal website was accessed for links to social media (SoMe). The number of ‘tweets’, followers and age of profile was determined. To evaluate the content, over a 6‐month period (November 2013 to April 2014), all tweets were scrutinised on the journals Twitter profiles. To assess SoMe influence, the Klout score of each journal was also calculated. Results In all, 33 urological journals were identified. Eight (24.2%) had Twitter profiles. The mean (range) number of tweets and followers was 557 (19–1809) and 1845 (82–3692), respectively. The mean (range) age of the twitter profiles was 952 (314–1758) days with an average 0.88 tweets/day. A Twitter profile was associated with a higher mean impact factor of the journal (mean [sd] 3.588 [3.05] vs 1.78 [0.99], P = 0.013). Over a 6‐month period, November 2013 to April 2014, the median (range) number of tweets per profile was 82 (2–415) and the median (range) number of articles linked to tweets was 73 (0–336). Of these 710 articles, 152 were Level 1 evidence‐based articles, 101 Level 2, 278 Level 3 and 179 Level 4. The median (range) Klout score was 47 (19–58). The Klout scores of major journals did not exactly mirror their impact factors. Conclusion SoMe is increasingly becoming an adjunct to traditional teaching methods, due to its convenient and user‐friendly platform. Recently, many of the leading urological journals have used Twitter to highlight significant articles of interest to readers.

  • Early adopters or laggards' Attitudes toward and use of social media
           among urologists
    • Authors: Michael Fuoco; Michael J. Leveridge
      First page: 491
      Abstract: Objective To understand the attitudes and practices of urologists regarding social media use. Social media services have become ubiquitous, but their role in the context of medical practice is underappreciated. Subjects and Methods A survey was sent to all active members of the Canadian Urological Association by e‐mail and surface mail. Likert scales were used to assess engagement in social media, as well as attitudes toward physician responsibilities, privacy concerns and patient interaction online. Results Of 504 surveys delivered, 229 were completed (45.4%). Urologists reported frequent or daily personal and professional social media use in 26% and 8% of cases, respectively. There were no differences between paper (n = 103) or online (n = 126; P > 0.05) submissions. Among frequent social media users, YouTube™ (86%), Facebook™ (76%), and Twitter™ (41%) were most commonly used; 12% post content or links frequently to these sites. The most common perceived roles of social media in health care were for inter‐professional communication (67%) or as a simple information repository (59%); online patient interaction was endorsed by 14% of urologists. Fewer than 19% had read published guidelines for online patient interaction, and ≤64% were unaware of their existence. In all, 94.6% agreed that physicians need to exercise caution personal social media posting, although 57% felt that medical regulatory bodies should ‘stay out of [their] personal social media activities’, especially those in practice 20 years (P = 0.02). Conclusion Practicing urologists engage infrequently in social media activities, and are almost universal in avoiding social media for professional use. Most feel that social media is best kept to exchanges between colleagues. Emerging data suggest an increasing involvement is likely in the continuing professional development space.

  • Clinical Efficacy of Collagenase Clostridium Histolyticum in the Treatment
           of Peyronie's Disease by Subgroups: Results From Two Large,
           
    • Abstract: Objectives To examine the efficacy of intralesional collagenase clostridium histolyticum (CCH) in defined subgroups of subjects with Peyronie's disease (PD). Subjects and Methods The efficacy of CCH compared with placebo from baseline to week 52 was examined in subgroups of subjects from the Investigation for Maximal Peyronie's Reduction Efficacy and Safety Studies (IMPRESS) I and II, defined by: severity of penile curvature deformity at baseline (30°‐60° [n=492] and 61°‐90° [n=120]); PD duration (1 to ≤2 [n=201], >2 to ≤4 [n=212], and >4 years [n=199]); degree of plaque calcification (no calcification [n=447], noncontiguous stippling [n=103], and contiguous calcification that did not interfere with the injection [n=62]); and baseline erectile function (International Index of Erectile Function [IIEF] 1‐5 [n=22], 6‐16 [n=106], and ≥17 [n=480]). Results Reductions in penile curvature deformity and PD symptom bother were observed in all subgroups. Penile curvature deformity reductions were significantly greater for CCH vs placebo for: baseline penile curvature 30°‐60° and 61°‐90°; disease duration >2 to ≤4 years and >4 years; no calcification; and IIEF ≥17 (high IIEF erectile function) (P < .05 for all). PD symptom bother reductions were significantly greater in the CCH group for: penile curvature 30°‐60°; disease duration >4 years; no calcification; and IIEF 1‐5 (no sexual activity) and ≥17 (P < .05 for all). Conclusions In this analysis, the clinical efficacy of CCH treatment for reducing penile curvature deformity and PD symptom bother was demonstrated across subgroups. In the IMPRESS I and II studies overall, AEs were typically mild or moderate, although treatment‐related serious AEs, including corporal rupture or penile hematoma, occurred. Future studies could be considered to directly assess the efficacy and safety of CCH treatment in defined subgroups of PD patients, with the goal of identifying predictors of optimal treatment success.

           resection on recurrence and progression rates in patients with high risk
           non muscle invasive bladder cancer treated with maintenance intravesical
           Bacillus Calmette‐Guerin
    • Abstract: Objectives To evaluate the effect of time lapse between the initial and second transurethral resection (TUR) on the outcome of patients with high risk nonmuscle invasive bladder cancer (NMIBC) treated with maintenance intravesical Bacillus Calmette‐Guerin (BCG) therapy. Materials and Methods We reviewed the data of patients from ten centers treated for high risk NMIBCbetween 2005 and 2012.Patients without a diagnosis of muscle invasive cancer on second TUR performed within 90 days after a complete first TUR, and received at least one year of maintenance BCG were included in this study.Time interval between first and second TUR in addition to other parameters were recorded.Multivariate logistic regression analysis was performed to identify predictors of recurrence and progression. Results A total of 242 patients were included in this study. The mean follow‐up period was 29.4±22.2 months (range 12‐96).The 3‐year recurrenceand progression free survival rates of patients who underwent second TUR between 14‐42 days and 43‐90 days were 73.6% vs. 46.2%(p=0.0001) and 89.1% vs. 79.1%(p=0.006), respectively. On multivariate analysis, time lapse to second TUR was found to be a predictor of both recurrence (OR 3.598, 95% CI 1.885–8.137, p =0.001) and progression (OR 2.144, 95% CI 1.447–5.137, p=0.003). Conclusions The time interval between first and second TUR should be≤ 42 days in order to obtain lower recurrence and progression rates. To our knowledge, this is the first study demonstrating the effect of time lapse between first and second TUR on patient outcomes. This article is protected by copyright. All rights reserved.
       
  • Diagnosis and treatment of chronic bacterial prostatitis and chronic
           prostatitis/chronic pelvic pain syndrome: a consensus guideline
    • Abstract: Objectives To improve awareness and recognition of these conditions among non‐specialists and patients. To provide guidance to healthcare professionals treating patients with CBP and CP/CPPS, in both non‐specialist and specialist settings. To promote efficient referral of care between non‐specialists and specialists and the involvement of the multidisciplinary team (MDT). Patients and Methods The guideline population were men with CBP or CP/CPPS (persistent or recurrent symptoms and no other urogenital pathology for ≥3 of the previous 6 months). Consensus recommendations for the guidelines were based on a search to identify literature on the diagnosis and management of CBP and CP/CPPS (published between 1999 and February 2014). A Delphi panel process was used where high‐quality, published evidence was lacking. Results CBP and CP/CPPS can present with a wide range of clinical manifestations. The 4 main symptom domains are urogenital pain, lower urinary tract symptoms (LUTS ‐ voiding or storage symptoms), psychological issues and sexual dysfunction. Patients should be managed according to their individual symptom pattern. Options for first‐line treatment include antibiotics, alpha‐adrenergic antagonists (if voiding LUTS are present) and simple analgesics. Repeated use of antibiotics such as quinolones should be avoided if there is no obvious symptomatic benefit from infection control or cultures do not support an infectious cause. Early use of treatments targeting neuropathic pain and/or referral to specialist services should be considered for patients who do not respond to initial measures. An MDT approach (urologists, pain specialists, nurse specialists, specialist physiotherapists, GPs, cognitive behavioural therapists/psychologists, sexual health specialists) is recommended. Patients should be fully informed about the possible underlying causes and treatment options, including an explanation of the chronic pain cycle. Conclusion Chronic prostatitis can present with a wide variety of signs and symptoms. Identification of individual symptom patterns and a symptom‐based treatment approach are recommended. Further research is required to evaluate management options for CBP and CP/CPPS. This article is protected by copyright. All rights reserved.
       
  • Guideline of Guidelines: Prostate Cancer Imaging
    • Abstract: In the era before the widespread adoption of PSA screening for prostate cancer, most incident cases were already advanced stage. Because treatment options such as surgery or radiation are thought mainly to benefit patients with localized disease, prostate cancer imaging was necessary prior to treatment of almost all patients. In the PSA era, however, over 90% of incident cases are localized, making the need for routine imaging with CT, MRI, or bone scan obsolete [1]. Numerous studies show a relatively low rate of positive staging imaging in low‐ and intermediate‐ risk patients. Recognizing these trends, several professional societies issued prostate cancer imaging guidelines in the mid‐1990s in an effort to curb the overuse of imaging.

  • Salvage Radical Prostatectomy for recurrent Prostate Cancer: Verification
           of EAU guideline criteria
    • Abstract: Objective To analyze oncological and functional outcomes of salvage radical prostatectomy (SRP) in patients with recurrent prostate cancer (PCa) and to compare outcomes of patients within and outside the EAU guideline criteria (organ‐confined PCa ≤ T2b, Gleason score ≤ 7 and preoperative PSA < 10 ng/mL) for SRP. Patients and Methods A total of 55 patients who underwent SRP from January 2007 to December 2012 were retrospectively analyzed. Kaplan‐Meier curves assessed time to biochemical recurrence (BCR), metastasis‐free survival (MFS) and cancer specific survival (CSS). Cox regressions addressed factors influencing BCR and MFS. BCR was defined as PSA>0.2 ng/ml and rising, continence as the use of 0‐1 safety pad per day and potency as an IIEF‐5 score ≥18. Results Median follow‐up was 36 months. Following SRP 42.0% of the patients experienced BCR, 15.9% developed metastasis and 5.5% died from PCa. Patients fulfilling EAU guideline criteria were less likely to have positive lymph nodes and had significantly better BCR‐free survival (5‐year BCR‐free survival 73.9% vs. 11.6% (p=0.001), respectively). In multivariate analysis, LDR‐brachytherapy as primary treatment (p=0.03) and presence of positive lymph nodes at SRP (p=0.02) were significantly associated with worse BCR‐free survival. The presence of positive lymph nodes or Gleason score > 7 at SRP were independently associated with metastasis. Urinary continence‐rate 1 year after SRP was 74%. Seven patients (12.7%) experienced complications ≥III (Clavien grade). Conclusion Salvage radical prostatectomy is a safe procedure providing good cancer control and reasonable urinary continence. Oncologic outcomes are significantly better in patients who met EAU guideline recommendations. This article is protected by copyright. All rights reserved.
       
  • Sampling of the anterior apical region results in increased cancer
           detection and upgrading in transrectal repeat saturation biopsy of the
           prostate
    • Abstract: Detection of clinically suspected prostate cancer using ultrasound‐guided transrectal biopsy is standard of care [1]. The relatively high probability of missing clinically significant cancers during initial sextant biopsies led to the introduction of extended 10‐12 core biopsy and subsequently to 20+ core saturation biopsy strategies [1–9]. Nevertheless, underdiagnosis of high risk prostate cancer even in patients with low PSA levels still occurs in 25‐30% [10,11].Anteriorly located prostate cancer contributes to these high rates and data from magnetic resonance imaging (MRI) studies underlines these considerations [12–14].

  • Pharmacological characterization of the relaxation induced by the soluble
           guanylate cyclase activator, BAY 60‐2770 in rabbit corpus cavernosum
           
    • Abstract: Objective To characterize the relaxation induced by the soluble guanylate cyclase (sGC) activator, BAY 60‐2770 in rabbit corpus cavernosum. Material and Methods Penis from male New Zealand rabbits were removed and fours strips of corpus cavernosum (CC) were obtained. Concentration‐response curves to BAY 60‐2770 were carried out in the absence and presence of inhibitors of nitric oxide synthase, L‐NAME (100 μM), sGC, ODQ (10 μM) and phosphodiestarase type 5, tadalafil (0.1 μM). The potency (pEC50) and maximal response (Emax) values were determined. Second, electrical‐field stimulation (EFS)‐induced contraction or relaxation was realized in the absence and presence of BAY 60‐2770 (0.1 or 1 μM) alone or in combination of ODQ (10 μM). In the case of EFS‐induced relaxation two protocols were realized: 1) ODQ (10 μM) was first incubated for 20 min and then BAY 60‐2770 (1 μM) was added for another 20 min (ODQ + BAY 60‐2770). In different CC strips, BAY 60‐2770 was incubated for 20 min followed by another 20 min with ODQ (BAY 60‐2770 + ODQ). The intracellular levels of cyclic guanosine monophosphate (cGMP) were also determined. Results BAY 60‐2770 potently relaxed rabbit CC with pEC50 and Emax values of 7.58 ± 0.19 and 81 ± 4%, respectively. The inhibitors ODQ (n=7) or tadalafil (n=7) produced 4.2‐ and 6.3‐leftward shifts, respectively in BAY 60‐2770‐induced relaxation without interfering on the Emax values. The intracellular levels of cGMP were augmented after stimulation with BAY 60‐2770 (1 μM) alone, whereas its co‐incubation with ODQ produced even higher levels of cGMP. The EFS‐induced contraction was reduced in the presence of BAY 60‐2770 (1 μM) and this inhibition was even greater when BAY 60‐2770 was co‐incubated with ODQ. The nitrergic stimulation induced CC relaxation, which was abolished in the presence of ODQ. BAY 60‐2770 alone increased the amplitude of relaxation. Co‐incubation of ODQ and BAY 60‐2770 did not alter the relaxation in comparison with ODQ alone. Interestingly, when BAY 60‐2770 was incubated prior to ODQ, EFS‐induced relaxation was partly restored in comparison with ODQ alone or ODQ + BAY 60‐2770. Conclusions Considering that the relaxation induced by the sGC activator, BAY 60‐2770 was increased after sGC oxidation and unaltered in the absence of nitric oxide, these class of substances are advantageous over sGC stimulators or PDE5 inhibitors for the treatment in those patients with erectile dysfunction and high endothelial damage.

  • Continence outcomes of robot assisted radical prostatectomy in patients
           with adverse urinary continence risk factors
    • Abstract: Objective To analyze the continence outcomes of robot assisted radical prostatectomy (RARP) in suboptimal patients that have challenging continence recovery factors: enlarged prostates, elderly patients, higher Body Mass Index (BMI), salvage prostatectomy and bladder neck procedures prior to RARP Material & Methods From January 2008 through November 2012, 4023 patients underwent RARP by a single surgeon at our institution. Retrospective analysis of prospectively collected data identified 3362 men who had minimum of one year of follow‐up. This cohort of patients was stratified into six groups: Group I, age 70 and over (n=451); Group II, BMI 35 and over (n=197); Group III, prior bladder neck procedures (n=103); Group IV, prostate weight 80 g and over (n=280); and Group V, salvage prostatectomy patients (n=41). Group VI consisted of patients (n=2447) with none of these risk factors. Continence outcomes at follow‐up were analyzed for all groups. Results The continence rate at 1 year and mean time to continence in different groups were for patients ≥70 years 85.6% and 3.2 ± 4.5 months; BMI ≥35 years 87.8% and 3.1 ± 4.5 months; prior bladder neck treatment 82.4% and 3.4 ± 4.7 months; prostate weight ≥80 g 85.8% and 3.3 ± 4.4 months; salvage procedures 51.3% and 6.6 ± 8.3 months and in Group VI, 95.1% and 2.4 ± 3.2 months. The continence rate was significantly higher in group VI in comparison to salvage group at different time intervals (p
