  • Chromogranin A and neuron‐specific enolase serum levels as
           predictors of treatment outcome in metastatic castration‐resistant
           prostate cancer patients under abiraterone therapy
    • Abstract: Objective To determine the impact of elevated neuroendocrine serum markers on treatment outcome in patients with metastatic castration‐resistant prostate cancer (mCRPC) undergoing treatment with abiraterone in a post‐chemotherapy setting. Patients and Methods Chromogranin A (CGa) and neuron‐specific enolase (NSE) were determined in serum drawn before treatment with abiraterone of 45 mCRPC patients. Outcome measures were overall survival (OS), prostate‐specific antigen (PSA) response defined by PSA decline ≥50%, PSA progression‐free survival (PSA‐PFS) and clinical or radiographic PFS. Results CGa and NSE serum levels did not correlate (p=0.6). Patients were stratified in a low (n=9), intermediate (n=18) or high (n=18) risk group according to elevation of none, one or both neuroendocrine markers. Risk groups correlated with decreasing median OS (median OS not reached vs. 15.3 vs. 6.6 months; p

  • Interpretation of conventional survival analysis and competing risk
           analysis: An example of hypertension and prostate cancer
    • Abstract: Most clinical studies use conventional methods for survival analysis and calculate the risk of the event of interest, however, it is important to understand that the study population is also at risk of competing events, for example death from other causes. Moreover, the risk of competing events may be dependent on the participants’ characteristics. Whether competing risks are taken into account or not, is of major importance when interpreting study results.Here, we use a practical example to elucidate the interpretational differences of absolute risk estimates obtained with both conventional methods for survival analysis and competing risk analysis.

  • Guidelines of Guidelines: Thromboprophylaxis for Urologic Surgery
    • Authors: Philippe D. Violette; Rufus Cartwright, Matthias Briel, Kari A.O. Tikkinen, Gordon H. Guyatt
      Abstract: The risks and benefits of thromboprophylaxis for urologic surgery depend on both patient specific and procedure specific factors [1,2]. Clinicians and patients must trade off a reduction in venous thromboembolism (VTE) against a potential increase in bleeding. Although investigators have not addressed the issue specifically for urological procedures, high quality evidence from randomized trials has demonstrated that pharmacological prophylaxis, with for example low molecular weight heparins (LMWH), decreases the risk of VTE in patients having abdominal or pelvic surgery by approximately 50% [1]. Best estimates for LMWH also suggest, however, an increase in the risk of post‐operative major bleeding by approximately 50% [1]. Although these relative risks are likely to be somewhat consistent across patients and procedures, the balance of benefits and harms varies with the absolute risk of VTE and bleeding. In patients with a high risk of VTE and a low risk of major bleeding, a 50% reduction in VTE represents a substantial benefit (for instance, from a baseline risk of 12% to 6%) and a 50% increase in bleeding represents a minimal increase in harm (for instance, from 0.2% to 0.3%). Patients whose risk of VTE without anticoagulation is low and whose bleeding risk is high face an opposite situation. This article is protected by copyright. All rights reserved.

      Abstract: Objective To evaluate change in platelet count (ΔPlt) as an indicator of response to primary tyrosine kinase inhibitor (TKI) therapy for metastatic renal cell carcinoma (mRCC). Patients and Methods Multi‐center retrospective analysis of mRCC patients undergoing primary TKI from 5/2005‐8/2014. ΔPlt was defined as post‐treatment platelet count after first cycle minus pre‐treatment platelet count. RECIST criteria were used to define partial response (PR), stable disease (SD), and progressive disease (PD). Analysis was conducted between subgroups with stable/increased (+ΔPlt) and decreased (‐ΔPlt) counts. Primary outcome was overall survival (OS) by Kaplan‐Meier analysis. Multivariable analysis (MVA) was conducted for risk factors associated with PD. Results 115 mRCC patients were analyzed, +ΔPlt 19 (16.6%) and –ΔPlt 96 (83%). More patients with +ΔPlt had Karnofsky score 2 metastases (78.9% vs. 51%, p=0.041). More patients with +ΔPlt had PD (89.4% vs. –ΔPlt 19.1%, p

  • Role of oral PentosanPolysulphate in reduction of local side effects of
           BCG in Non muscle invasive Bladder Cancer patients: a pilot study
    • Authors: Suresh Yadav; Vinay Tomar, Sher Singh Yadav, Shivam Priyadarshi, Indraneel Banerjee
      Abstract: Objective Intravesical immunotherapy with Bacillus Calmette–Guerin (BCG) is indicated for the treatment of high grade Ta/T1 non‐muscle invasive bladder cancer (NMIBC); but it is associated with significant local side effects. Aim of the study was to assess the role of oral Pentosan Polysulphate (PPS) in reduction of BCG related local side‐effects. Methods 32 symptomatic patients after BCG instillation were randomized into three groups: A, B and C. Group A received placebo (vitamin B complex tablet) in t.i.d dose, Group B received PPS 100 mg t.i.d. dose and Group C received PPS 100mg o.d and placebo (vitamin B complex tablet b.i.d dose) for 6 weeks. Visual Analog Scale (VAS) for bladder pain, Overactive Bladder‐Validated 8 Question Screener (OAB‐V8) and dysuria were evaluated in three groups before and during each weekly visit of BCG instillation. Results Post treatment mean VAS score was significantly lower in Group B (4.4±1.2) and C (5.8±0.8) as compared to group A (8±0.4).Also, the post treatment VAS score was significantly lower in group B v/s group C(p

      Abstract: Objective To report the independent prognostic impact of the new prostate cancer grade grouping system in a large external validation cohort of patients treated with radical prostatectomy. Subjects/patients Between 1994 and 2013, 3,694 consecutive men were treated by radical prostatectomy at a single institution. To investigate the performance of and validate the grade‐grouping system, biochemical recurrence‐free survival (bRFS) rates were assessed using Kaplan Meier tests, Cox‐regression modeling, and discriminatory comparison analyses. Separate analyses were performed based on biopsy and prostatectomy grade. Results Median follow‐up was 52.7 months. The 5‐year actuarial bRFS for biopsy grade‐groups 1‐5 were 94.2%, 89.2%, 73.1%, 63.1%, and 54.7%, respectively (p

  • Steroid co‐introduction with docetaxel chemotherapy for metastatic
           castration‐resistant prostate cancer affects PSA flare
    • Abstract: Objective To investigate the potential relationship of steroid usage with prostate‐specific antigen (PSA) flare and the prognostic impact of PSA flare, which is known to occur in 10–20% of patients with metastatic castration‐resistant prostate cancer during docetaxel chemotherapy. Patients and Methods This study included 71 patients with metastatic castration‐resistant prostate cancer treated by docetaxel chemotherapy with co‐introduction of steroid. PSA flare was defined as transient PSA increase followed by PSA decrease. Results PSA flare was recognized in 7.0–23.9% of patients according to various definitions. Intriguingly, men with steroid intake before the initiation of docetaxel chemotherapy experienced significantly fewer PSA flares. The progression‐free survival rate in men with PSA flare was equivalent to that of PSA responders, but significantly better than men with PSA failure. Conclusions Our results suggest that de novo steroid co‐introduction with docetaxel chemotherapy induce the PSA flare phenomenon. This novel finding may account for the mechanism of PSA flare as well as being valuable for distinguishing PSA elevation as PSA flare or failure. This article is protected by copyright.

  • ATRIGEL® polymer‐delivered subcutaneous leuprolide acetate
           formulations achieve and maintain castrate levels of testosterone in four
           open label studies in advanced prostate cancer patients
    • Authors: Neal D. Shore; Franklin Chu, Judd Moul, Daniel Saltzstein, Raoul Concepcion, John A. McLane, Stuart Atkinson, Alex Yang, E. David Crawford
      Abstract: Objective To determine whether an LHRH agonist, ATRIGEL® polymer‐delivered, subcutaneous, leuprolide acetate (ADSC‐LA) formulations suppressed testosterone to levels ≤20 ng/dL. Subjects/Patients and Methods Data from four open‐label, fixed‐dose studies were evaluated. Male patients aged 40‐86 years with advanced prostatic adenocarcinoma, whom had not undergone prior ADT, were treated with a depot formulation of ADSC‐LA: 7.5 mg [1 month (1M); N=120], 22.5 mg [3 months (3M); N=117], 30 mg [4 months (4M); N=90], or 45 mg [6 months (6M); N=111]. Serum testosterone was sampled at screening, baseline, 2, 4, 8 hours post‐dosing, days 1, 2, 3, 7, and every week until the next dose, at which time, the sampling schedule repeated until the end of study (24 weeks for 1M and 3M, 32 weeks for 4M, and 48 weeks for the 6M dose). The primary analyses were mean serum testosterone levels and proportion of patients who achieved serum testosterone levels ≤20 ng/dL. Results Mean serum testosterone levels at the end of study were consistently ≤20 ng/dL in each study (6.1±0.4, 10.1±0.7, 12.4±0.8, 12.6±2.1 for the 1M, 3M, 4M, and 6M doses, respectively). A high proportion of patients (94%, 90%, 92%, 96% for 1M, 3M, 4M, and 6M doses, respectively) achieved testosterone levels ≤20 ng/dL within 6 weeks, and 90‐97% of patients in all studies maintained testosterone ≤20 ng/dL from weeks 6‐24. Conclusions Recent studies have demonstrated improved outcomes in prostate cancer patients who consistently attained a more rigorous level of testosterone suppression (≤20 ng/dL) with androgen deprivation therapy (ADT) than the historical standard (≤50 ng/dL). All doses of ADSC‐LA rapidly achieved and maintained mean serum testosterone to the more rigorous target level of T ≤20 ng/dL. These data suggest that ADSC‐LA delivers equivalent testosterone suppression as achieved by surgical castration. This article is protected by copyright. All rights reserved.

      Abstract: Objectives To evaluate the influence of posterior musculofascial plate reconstruction (PR) on early return of continence after radical prostatectomy (RP). An updated systematic review of the literature. Material and Methods A systematic review of the literature was performed in June 2015, following the PRISMA statement and searching Medline, Embase, Scopus and Web of Science databases. We searched the terms posterior reconstruction prostatectomy, double layer anastomosis prostatectomy across the Title and Abstract fields of the records, with the following limits: humans, gender (male), and language (English). The authors reviewed the records to identify studies comparing cohorts of patients who underwent RP with or without restoration of the posterior aspect of the rhabdosphincter. A meta‐analysis of the risk ratios estimated using data from the selected studies was performed. Results Twenty‐one studies were identified in the literature search, including three randomized controlled trials. The overall analysis of comparative studies showed that PR improves the early continence recovery at 3‐7, 30 and 90 days after catheter removal, while continence rate at 6 months is statistically but not clinically affected. Statistically significant lower anastomotic leakage rates were described after PR. No significant differences were found in terms of positive surgical margins rates or for complications such as acute urinary retention and bladder neck stricture. Conclusions The analysis confirms the benefits at 30 days post catheter removal already discussed in the review published in 2012 but also shows a significant advantage in terms of urinary continence recovery in the first 3 months. A multicenter prospective randomized controlled trial is currently conducted in several institutions all over the world to better assess the effectiveness of the PR in facilitating an earlier recovery of postoperative urinary continence.

    • Authors: Roderick CN den Bergh; Theo H der Kwast, Jeroen Jong, Homayoun Zargar, Andrew J Ryan, Anthony J Costello, Declan G Murphy, Henk G der Poel
      Abstract: In 2014 the International Society of Urological Pathology (ISUP) supported to change the ISUP‐2005 modified Gleason scoring system, as previously proposed by Pierorazio et al.[1,2] Besides decisions on terminology and scoring of specific morphological patterns, a renumbering of the existing scores was suggested.[3] In clinical practice this comprises a transformation from a 6‐10 risk spectrum including 9 different Gleason scores (3+3=6, 3+4=7, 4+3=7, 3+5=8 4+4=8, 5+3=8, 4+5=9, 5+4=9, and 5+5=10) to a 1‐5 score with 5 grade groups (1: ≤3+3, 2: 3+4, 3: 4+3, 4: Gleason scores 8, and 5: Gleason score 9‐10).

  • Assessment of energy density usage during 180W lithium triborate laser
           photo‐selective vaporization of the prostate for benign prostatic
           hyperplasia. Is there an optimal amount of kilo‐Joules per gram of
           prostate?
    • Abstract: Objectives The ideal amount of energy delivery during photo‐selective vaporization of the prostate (PVP) for optimal treatment of benign prostate hyperplasia (BPH) has not been established. The aim of this study is to assess the effect of energy density (kJ/cc) applied on adenoma during treatment on functional outcomes, PSA reduction and complications. Subjects/patients and methods After exclusions, a total of 440 patients that underwent Greenlight laser XPS 180W LBO PVP for the treatment of BPH were retrospectively reviewed. Data was collected from seven different international centers (Canada, the United States, the United Kingdom and France). Patients were stratified into four energy density groups (kJ/cc) according to intraoperative energy delivered and prostate volume as determined by pre‐operative trans‐rectal ultrasound (TRUS): group 1: 50%) at 6,12 and 24 months suggesting increased vaporization of adenoma tissue. However this did not translate into differences in functional outcomes at two years of follow‐up. This article is protected by copyright. All rights reserved.

  • Risk of prostate cancer specific death in men with baseline metabolic
           aberrations treated with androgen deprivation therapy for biochemical
           recurrence
    • Authors: Sarah M. Rudman; Kathryn P. Gray, Julie L. Batista, Michael J. Pitt, Edward L. Giovannucci, Peter G. Harper, Massimo Loda, Lorelei A. Mucci, Christopher J. Sweeney
      Abstract: Objectives To investigate the association of host metabolic factors and the metabolic syndrome on prostate cancer specific death (PCSD) and overall survival (OS) in patients treated with androgen deprivation therapy (ADT) for biochemically recurrent disease. Patients and Methods The analysis included 273 prostate cancer patients treated with ADT for rising PSA after surgery or radiotherapy. Patients were assessed for the presence of diabetes, hypertension, dyslipidaemia, and obesity prior to the commencement of ADT and using ATPIII criteria for the presence of the composite diagnosis of metabolic syndrome (MS). Competing risks regression model assessed associations of time to PCSD with the metabolic conditions, while multivariable Cox regression model assessed associations of OS with MS and metabolic conditions. Results During a median follow‐up of 11.6 years, 157 (58%) patients died, of which 58 (21%) died of prostate cancer. At the start of ADT the median age was 74 (range=46, 92) years, the median PSA was 3.0 ng/mL. MS were observed in 31% patients; hypertension (68%) and dyslipidaemia (47%) were the most common metabolic conditions. No association of PCSD and MS status was observed. Patients with hypertension tended to have a higher cumulative incidence of PCSD compared to those without hypertension (sub‐distribution hazards ratio HR=1.59 (95%CI 0.89, 2.84; p‐value=0·11) though not statistically significant. Patients with MS had an increased risk of death from all causes (HR=1.56, 95%CI: 1.07, 2.29; p=0.02) when compared with patients without MS; as did patients with hypertension (HR=1·72, 95% CI: 1·18‐2·49; p=0·004). Conclusions No association of prostate cancer specific death and metabolic syndrome was observed in this cohort of men receiving ADT for biochemically recurrent prostate cancer. Patients with MS were associated with an increased risk of death from all causes and a similar effect was also observed for prostate cancer patients with hypertension alone.

  • Risk factors and timing of venous thromboembolism after radical cystectomy
           in routine clinical practice: a population‐based study
    • Authors: R. Christopher Doiron; Christopher M. Booth, Xuejiao Wei, D. Robert Siemens
      Abstract: Objective To describe the risk factors and timing of perioperative venous thromboembolism (VTE) and its association with survival for patients undergoing radical cystectomy (RC) in routine clinical practice. Patients and Methods The population‐based Ontario Cancer Registry was linked to electronic records of treatment to identify all patients who underwent RC between 1994 and 2008; VTE events were identified from hospital diagnostic codes. Multivariate logistic regression analysis was used to determine the factors associated with perioperative VTE. A Cox proportional hazards regression model explored the associations between VTE and survival. Results Of the 3 879 patients included in the study, 3.6% (141 patients) were diagnosed with VTE at ≤1 month of their surgical admission date. This increased to 4.7% (181) at ≤2 months and 5.4% (211) at ≤3 months. In all, 55% of VTE events presented after hospital discharge. In multivariate analysis, factors associated with VTE included higher surgeon volume (P = 0.004) and increased length of hospital stay (LOS; P < 0.001). Lymph node yield and adjuvant chemotherapy were not associated with VTE. VTE was associated with an inferior cancer‐specific survival [hazard ratio (HR) 1.35, 95% confidence interval (CI) 1.13–1.62] and overall survival (HR 1.27, 95% CI 1.08–1.49). Conclusions Over half of VTE events in RC patients occur after hospital discharge, with a substantial incidence up to 3 months after surgery. Limited actionable risk factors for VTE were identified other than LOS. In this population‐based cohort, VTE was associated with inferior long‐term survival.

      Abstract: Objectives To determine the relationship of age to side effects leading to discontinuation of treatment in stage Ta‐T1 NMIBC patients treated with maintenance bacillus‐Calmette‐Guérin (BCG). Patients and Methods We evaluated toxicity for 487 eligible intermediate or high risk Ta‐T1 (without CIS) non‐muscle‐invasive bladder cancer (NMIBC) patients randomized to receive 3 years of maintenance BCG (247 BCG alone and 240 BCG+INH) in EORTC trial 30911. The percent of patients who stopped for toxicity and the number of treatment cycles that they received were compared in 4 age groups, < 60, 61 ‐ 70, 71 – 75 and > 75 years of age, using the Mantel‐Haenszel chi square test for trend. Results The percent of patients stopping BCG for toxicity was 17.9% in patients < 60, 21.9% in patients 61 – 70, 22.9% in patients 71 – 75, and 16.4% in patients > 75 years of age (p = 0.90). For both systemic and local side effects, there was likewise no significant difference. Conclusions In intermediate and high risk Ta T1 urothelial bladder cancer patients treated with BCG, no differences in toxicity as a reason for stopping treatment were observed based on age.

  • The association of eNOS G894T gene polymorphisms with responsiveness to
           α1‐blocker in men with BPH/LUTS
    • Abstract: Objective Nitric oxide (NO) has recently gained increasing recognition as an important neurotransmitter of functions in the lower urinary tract. This prospective study firstly investigated the association of eNOS G894T gene polymorphism with the responsiveness to α1‐blocker in men with benign prostatic hyperplasia related lower urinary tract symptoms (BPH/LUTS). Materials and Methods 136 patients with BPH/LUTS were recruited from urology outpatient clinics in a university hospital. Oral therapy with doxazosin‐ GITS 4 mg once‐daily was given for 12 weeks. The drug efficacy was assessed by the changes from baseline in the total International Prostate Symptom Score (IPSS), maximum urinary flow rate (Qmax) and post‐void residual urine volume (PVR) at 12 weeks of treatment. The responders to doxazosin GITS were defined as those who had a total IPSS decrease of more than 4 points from baseline. The eNOS G894T polymorphisms were determined using the polymerase chain reaction‐restriction fragment length polymorphism (PCR‐RFLP) method Results Patients had statistically significant improvements in total IPSS, QoL and Qmax (P

  • Prostate biopsy, targeted prophylaxis and infectious complications: A
           critique of methods used
    • Authors: Matthew J. Roberts; Suhail A. Doi
      Abstract: Transrectal ultrasound (TRUS) guided prostate biopsy (TRUSPB) is commonly performed to sample the prostate while breaching rectal mucosa. This approach is associated with a considerable risk of uncommon infectious complications, including sepsis, which have been reported to be occurring more frequently [1]. Peri‐biopsy antimicrobial prophylaxis, predominantly using fluoroquinolones, reduces infectious complications, however with increasing antimicrobial resistance observed worldwide, different approaches are being considered. A “targeted” prophylaxis approach, where rectal swabs are used to detect fluoroquinolone‐resistant rectal flora, has been proposed and shown to be beneficial in various prospective cohort studies [2].

  • The Final Robotic Frontier: Evolution and Current State of the
           Robotic‐Assisted Radical Cystectomy
    • Authors: Tony Tran; Nicholas Raison, Norbert Doeuk, Prokar Dasgupta
      Abstract: Radical cystectomy with pelvic lymphadenectomy and urinary diversion has long been the standard of care for the treatment of non‐metastatic muscle‐invasive urothelial carcinoma of the bladder. Historically the procedure was performed through an open technique. With the potential benefits of decreased blood loss, quicker return of bowel function, and shorter postoperative convalescence minimally invasive techniques began to be described in the 1990s. Menon et al performed the first robotic‐assisted radical cystectomy in 2003 and the first centres soon adopted the procedure (1). Yet surprisingly, unlike other robotic‐assisted procedures, the technique has not enjoyed a similarly meteoric rise. This article is protected by copyright. All rights reserved.

Methods Survivin expression was evaluated by immunohistochemistry on a tissue microarray of RP cores from 3117 patients. Survivin expression was considered altered when at least 10% of the tumor cells stained positive. Association of altered Survivin expression with BCR was evaluated using Cox proportional hazards regression models. Results Survivin expression was altered in 1330 (42.6%) patients. Altered expression was associated with higher Gleason score on RP (p=0.001), extracapsular extension (p=0.019), seminal vesicle invasion (p

      Abstract: Objective To assess the value of the Prostate Imaging Reporting and Data System (PI‐RADS) scoring system, for prostate multi‐parametric magnetic resonance imaging (mpMRI) to detect prostate cancer, and classical parameters, such as prostate specific antigen (PSA), prostate volume and PSA density, for predicting biopsy outcome in biopsy naïve patients who have suspected prostate cancer (PCa). Patients and methods Patients who underwent mpMRI at our hospital, and who had their first prostate biopsy between July 2010 and April 2014, were analysed retrospectively. The prostate biopsies were performed transperineally under transrectal ultrasound guidance. Fourteen cores were biopsied as a systemic biopsy in all patients. Two cognitive fusion‐targeted biopsy cores were added for each lesion in patients who had suspicious or equivocal lesions on mpMRI. The PI‐RADS scoring system ver. 2.0 (PI‐RADS v2) was used to describe the MRI findings. Univariate and multivariate analyses were performed to determine significant predictors of PCa and clinically significant PCa. Results In total, 288 patients were analysed. Median patient age, PSA, prostate volume and PSA density were 69, 7.5 ng/mL, 28.7 cm3 and 0.26 ng/mL/cm3, respectively. The biopsy results were benign, clinically insignificant and clinically significant PCa in 129 (45%), 18 (6%) and 141 (49%) patients, respectively. The multivariate analysis revealed that PI‐RADS v2 score and PSA density were independent predictors for PCa and clinically significant PCa. When PI‐RADS v2 score and PSA density were combined, PI‐RADS v2 score > 4 and PSA density > 0.15, or PI‐RADS v2 score 3 and PSA density > 0.30, was associated with the highest clinically significant PCa detection rates (76–97%) on the first biopsy. Of the patients in this group with negative biopsy results, 22% were subsequently diagnosed as PCa. In contrast, PI‐RADS v2 score < 3 and PSA density < 0.15 yielded no clinically significant PCa and no additional detection of PCa on further biopsies. Conclusions A combination of PI‐RADS v2 score and PSA density can help in the decision‐making process before prostate biopsy and the follow‐up strategy in biopsy naïve patients. Patients with PI‐RADS v2 score < 3 and PSA density < 0.15 may avoid unnecessary biopsies. This article is protected by copyright. All rights reserved.

      Abstract: Objective To evaluate the prognostic impact of tumor size on survival outcomes in upper urinary tract urothelial carcinoma (UTUC) treated with radical nephroureterectomy (RNU). Patients and Methods Data on 795 patients treated with RNU for UTUC from 7 centers were retrospectively analyzed with focus on tumor size. Clinicopathological features and relevent prognostic factors were compared between patients with tumor size ≤3.0cm and >3.0cm. The primary end points were cancer specific survival (CSS), disease recurrence‐free survival (DFS), and overall survival (OS). Results At a median follow‐up of 32 months, 313 (39.4%) patients died of UTUC, 321 (40.4%) developed cancer relapse, and 359 (45.1%) died of all causes. Tumor size >3.0cm was associated with unfavorablly clinicopathlogical features. On Kaplan–Meier analysis, tumor size was significantly correlated with worse CSS, DFS and OS(all p

      Abstract: Objective To determine the safety of robot‐assisted cystectomy in patients with an irradiated pelvis, by comparing perioperative complication outcomes after robot‐assisted cystectomy in patients with and without a history of pelvic irradiation. Patients and Methods A total of 252 consecutive patients underwent robot‐assisted cystectomy at a tertiary referral center from 2002 and 2013. Of all patients, 46 (18%) had a history of pelvic irradiation. ● Complications occurring within 30 days and 90 days of surgery were graded using the modified Clavien classification system and additionally categorized by organ system. ● Baseline variables and outcomes of irradiated and non‐irradiated patients were compared using descriptive statistics. Multivariable logistic regression models were generated to test the effect of previous pelvic irradiation on complications. Results The indications for robot‐assisted cystectomy in patents with a history of pelvic irradiation were: bladder cancer (n=30, 65%), prostate cancer (n=2, 4%), fistulas (n=5, 11%) and intractable symptoms from radiation cystitis (n=9, 20%). ● A total of 25 (54%) irradiated and 112 (54%) non‐irradiated patients had complications within 90 days (p>0.9), of which 11 (24%) and 43 (21%) had major complications (p=0.7). ● One (2%) patient with and two (1%) patients without a history of irradiation died from surgical complications (p=0.5). ● Infectious, bleeding and gastrointestinal complications were the most common events in both groups. ● In multivariable analyses, a history of pelvic irradiation was not associated with higher risk of complications. Conclusion Robot‐assisted cystectomy performed by an experienced surgeon is a reasonable option in selected patients with a history of pelvic irradiation, as complication rates do not significantly differ compared to non‐irradiated patients.

      Abstract: Objectives To compare perioperative outcomes and quality of life (QoL) in a series of elderly patients with high co‐morbidity status who underwent single stoma cutaneous ureterostomy (CU) or ileal conduit (IC) after radical cystectomy (RC). Subjects and methods Clinical records of patients older than 75 years with an American Society of Anesthesiologists (ASA) score > 2 who underwent RC at a single institution between March 2009 and March 2014 were retrospectively analyzed. After RC, all patients included in the study received an IC urinary diversion or a CU with single stoma urinary diversion. Preoperative clinical characteristics as well as intra and post‐operative outcomes were evaluated and compared in the two groups. Moreover, the Bladder Cancer Index (BCI) was used to assess QoL. Results A total of 70 patients were included into the final comparative analyses. Of them, 35 underwent IC diversion and 35 CU with single stoma diversion. The two groups were comparable for age, gender, ASA score, type of indication and pathological features. Operative times (p

      Abstract: Objectives To compare multiparametric magnetic resonance imaging of the prostate (mpMRI) and histological findings of targeted MRI/ultrasound‐fusion biopsy (fusPBx) and systematic biopsy (sysPBx) to final histology of prostatectomy specimen (PrS). Patients and methods 105 patients with histopathologically proven prostate cancer (PCa) by combination of fusPbx and sysPBx and undergoing radical prostatectomy were investigated. All patients had been examined by mpMRI, applying the European Society of Urogenital Radiology criteria. Histological findings of PrS were compared to those of the biopsy. Whole mount PrS and MR‐images were compared directly by a uro‐pathologist and a uro‐radiologist in step‐section analysis. Results 105 patients with histopathologically proven PCa by combination of fusPBx and sysPBx (combPBx) were investigated. The detection rate of PCa was 90% (94/105) in fusPBx alone and 68% (72/105) in sysPBx alone (p=0.001). CombPBx detected 23 (22%) Gleason Score (GS) 6, 69 (66%) GS 7 and 13 (12%) GS ≥8 tumours. FusPBx alone detected 25 (26%) GS 6, 57 (61%) GS 7 and 12 (13%) GS ≥8 tumours. SysPBx alone detected 17 (24%) GS 6, 49 (68%) GS 7 and 6 (8%) GS ≥8 tumours. FusPBx alone would have missed 11 tumours (4% (4/105) (GS) 6; 6% (6/105) GS 7; 1% (1/105) GS ≥8), sysPBx alone would have missed 33 tumours (10% (10/105) GS 6; 20% (21/105) GS 7; 2% (2/105) GS ≥8). Concordance on GS between biopsy and PrS was 63% (n=65), 54% (n=56) and 75% (n=78) in fusPBx, in sysPBx and in the combination of both biopsy modalities (combPBx), respectively. Upgrading on GS between biopsy and PrS occurred in 33% (n=34), 44% (n=46) and 18% (n=19) in fusPBx, sysPBx and combPBx, respectively. Gamma correlation for detection of any cancer was 0.76 for combPBx, 0.68 for fusPBx alone and 0.23 for sysPBx alone. 84% (n=88) of index tumours could be identified by mpMRI; 86% (n=91) of index lesions in the mpMRI could be proven in PrS. Conclusions FusPBx of tumour suspicious lesions in mpMRI was associated with a higher detection rate of more aggressive PCa and a better tumour prediction in final histopathology than sysPBx alone. But combPBx has been shown the best concordance for the prediction of GS. Furthermore, the additional findings of sysPBx reflect the multifocality of PCa. Hence, the combination of both biopsy modalities would still present the best approach for the prediction of the final tumour grading in PCa. This article is protected by copyright.

      Abstract: Introduction To analyse the performance of the Prostate Cancer Prevention Trial Risk Calculator (PCPT‐RC) and two iterations of the European Randomised Study of Screening for Prostate Cancer Risk Calculator (ERSPC‐RC), one of which incorporates prostate volume and another which incorporates prostate volume and the Prostate Health Index (ERSPC‐PHI) in a referral population. Methods The risk of prostate cancer (PCa) and significant PCa (Gleason ≥7) in 2,001 patients from 6 tertiary referral centres was calculated according to the PCPT‐RC and ERSPC‐RC formulae. The calculators’ predictions were analysed using the area under the receiver operating characteristics curve (AUC), calibration plots, Hosmer‐Lemeshow test for goodness of fit and decision curve analysis. In a subset of 222 patients for whom the Prostate Health Index (PHI) score was available, each patient's risk was calculated as per the ERSPC‐RC and ERSPC‐PHI risk calculator. Results The ERSPC‐RC outperformed the PCPT‐RC in the prediction of PCa, with an AUC of 0.71 compared to 0.64 and also outperformed the PCPT‐RC in the prediction of significant PCa (p

  • Prostate specific antigen patterns in US and European populations:
           comparison of six diverse cohorts
    • Abstract: Objective To determine whether there are differences in prostate specific antigen (PSA) at diagnosis or changes in PSA between US and European populations of men with and without prostate cancer. Subjects and methods Repeated measures of PSA from six clinically and geographically diverse patient cohorts: two cohorts of men with PSA‐detected prostate cancer, two cohorts with clinically‐detected prostate cancer and two cohorts of men without prostate cancer. Using multilevel models, average PSA at diagnosis and PSA change over time were compared between populations. Results Annual percentage PSA change of 4‐5% was similar between men without cancer and men with PSA‐detected cancer. PSA at diagnosis was 1.7ng/ml lower in a US cohort of PSA‐detected men (95% CI 1.3‐2.0ng/ml), compared to a PSA‐detected UK cohort, but there was no evidence for a different rate of PSA change between these populations. Conclusion PSA changes over time are similar in UK and US men diagnosed through PSA testing and even in men without prostate cancer. Further development of PSA models to monitor men on active surveillance should be undertaken in order to take advantage of these similarities. We found no evidence that guidelines for using PSA to monitor men cannot be passed between US and European studies. This article is protected by copyright. All rights reserved.

      Abstract: Objectives To evaluate the cancer detection rates (CDR) for men undergoing 12 core systematic prostate biopsy with negative prebiopsy mpMRI (NegMR). Materials & Methods Clinical data from consecutive men undergoing prostate biopsy with prebiopsy 3T mpMRI from December 2011 to August 2014 were reviewed from an IRB approved prospective database. Prebiopsy mpMRI was read by a single radiologist and men with NegMR prior to biopsy were identified for this analysis. Clinical features, CDR, and NPV rates were summarized. Results Seventy five men underwent SPB with a NegMRI during the study period. For the entire cohort, men with no prior biopsy, men with prior negative biopsy, and men enrolled in active surveillance protocols, overall CDR was 18.7%, 13.8%, 8.0% and 38.1%, respectively, and detection of Gleason sum ≥ 7 (GS≥7) cancer was 1.3%, 0%, 4.0% and 0%, respectively. The NPV for all cancers was 81.3%, 86.2%, 92.0%, and 61.9%, and for GS≥7 cancer was 98.7%, 100%, 96.0% and 100%, respectively. Conclusions Negative prebiopsy mpMRI confers an overall NPV of 82% on 12 core biopsy for all cancer and 98% for GS≥7. Based upon biopsy indication, these findings assist in prebiopsy risk stratification for detection of high risk disease and may provide guidance in the decision to pursue biopsy.

  • Abnormal Akt signaling in bladder epithelial cell explants from IC/BPS
           patients can be induced by antiproliferative factor treatment of normal
           bladder cells
    • Abstract: Objectives Explanted bladder epithelial cells from IC/BPS patients produce a frizzled 8‐related glycopeptide antiproliferative factor (APF) that inhibits normal bladder epithelial cell proliferation and expression of several proteins known to be regulated by Akt signaling. • Our primary objective was to determine whether Akt signaling and secretion of specific downstream effector proteins are abnormal in specific cell fractions of IC/BPS bladder epithelial cells. • A related secondary objective was to determine whether treatment of normal bladder epithelial cells with active synthetic asialo‐antiproliferative factor (as‐APF) induces similar changes in Akt signaling and specific downstream effector proteins/mRNAs. Patients and Methods • Cell proteins were extracted into four subcellular fractions from primary bladder epithelial explants of six patients who fulfilled modified NIDDK criteria for IC/BPS and six age‐ and gender‐ matched controls. • Total and/or phosphorylated cellular Akt, GSK3β, and β‐catenin; total cellular JunB; and secreted MMP2 and HB‐EGF levels were determined by Western blot. • MMP2, JunB, p53, UPK3, and β‐actin mRNAs were quantified by qRT‐PCR. • Akt activity was determined by nonradioactive assay. Results • IC/BPS cells had decreased Akt activity, along with decreased Akt ser473‐ and GSK3β ser9‐phosphorylation and increased β‐catenin ser33,37/thr41‐phosphorylation in specific fractions as compared to matched control cells. • IC/BPS explants also had evidence for additional downstream abnormalities as compared to control cells, including decreased nuclear JunB; decreased secreted MMP2 and HB‐EGF; plus decreased MMP2, JunB, and UPK3 mRNAs but increased p53 mRNA relative to β‐actin. • Each of these IC/BPS cell abnormalities was also induced in normal cells by as‐APF. Conclusion • These findings indicate that IC/BPS cells have abnormal Akt activity with downstream protein expression abnormalities including decreased MMP2 and HB‐EGF secretion. • They also support the hypothesis that APF plays a role in the pathogenesis of IC/BPS via its effects on cell Akt signaling and HB‐EGF production.

  • Factors predicting progression to castrate‐resistant prostate cancer
           in patients with advanced prostate cancer receiving long‐term
           androgen deprivation therapy
    • Abstract: Objectives To assess time to progression to castrate‐resistant prostate cancer (CRPC) and factors influencing longer‐term outcomes in patients receiving ADT in an extension to the Triptocare study (NCT01020448). This is pertinent as the Triptocare study did not show that urinary PCA3 score was a reliable marker of cancer stage in advanced prostate cancer and was not useful for assessing response 6 months after initiation of androgen deprivation therapy (ADT) with triptorelin 22.5 mg. Patients and methods An international, multicentre, non‐interventional, observational, longitudinal, prospective study involving patients from the Triptocare study. CRPC status of patients was collected for up to 3 years from ADT initiation. Patient treatment and assessments were at the investigator's discretion. Co‐primary endpoints were rate of CRPC 3 years after initiating ADT and median time to CRPC. An exploratory endpoint was association of Triptocare baseline variables (including TMPRSS2‐ERG score and PCA3 score) and PCA‐3 score at Triptocare last value available with CRPC onset. Results Of the 325 patients in the Triptocare study safety population, 180 patients were enrolled in the Triptocare LT study (102 received continuous and 78 received intermittent ADT). CRPC rates at 3 years were 24/102 (23.5%) and 6/78 (7.7%) patients in the continuous and intermittent ADT groups, respectively. Median time to CRPC was not reached for either group. PCA3 score status at baseline was the only variable associated with a higher risk of progression to CRPC in both the intermittent and continuous ADT groups; compared with a baseline PCA3 score ≥35, PCA3 score below the level of quantification (BLQ) had a hazard ratio (HR) of 20.04 (95% CI: 2.71–148.34) and a HR=9.44 (95% CI: 2.39–37.27), respectively. Baseline metastatic disease and testosterone were additionally associated with progression to CRPC in the continuous ADT population: HR=5.20 (95%CI: 1.68–16.06) and HR=0.995 (95%CI: 0.991–0.999), respectively. Conclusion In men with locally‐advanced or metastatic prostate cancer, a PCA3 score ≥35 at time of initiating ADT may predict a lower risk of developing CRPC in the following 3 years.

           independent risk factor for cardiovascular disease”
    • Abstract: In a recent volume of this journal, the possible association between LUTS and cardiovascular disease (CVD) was highlighted [1, 2]. This topic is of interest with an ageing population. Particularly in urology, the consultation rates for male LUTS highly depend on patient age. Fortunately, nowadays specialists see their patients in a broader perspective, than their single condition, taking comorbidities into consideration as well. The growing attention for CVD risk in men with LUTS illustrates this. This article is protected by copyright. All rights reserved.

           Emergency Department
    • Authors: Li June Tay; Hannah Lyons, Irene Karrouze, Claire Taylor, Azhar A. Khan, Peter M. Thompson
      Abstract: Objectives To conduct an audit of patients presenting with long‐term urinary catheter (LTC)‐associated problems to our Emergency Department (ED) and to assess the availability of community nursing support for their LTC. We also estimated the cost implication to the health service and the potential solutions to this issue, as although catheter care is provided by community nurses, LTC problems are common presentations to the ED and are often significant burdens to the services. Patients and Methods A study was carried out of all patients presenting to the ED with a urinary catheter problem, specifically studying LTCs and the reason for presentation, district nurses' involvement, and the intervention received. Results In all, 78 patients with a urinary catheter problem presented to the ED over a 69‐day period, of whom 59 (68%) had a LTC. In all, 33 patients (42%) attended during normal working hours between 0900 and 1700 h. The mean (range) age was 74 (42–93) years and the duration the LTC had been in situ was 11 (1–120) months. The most common reasons for attendance were blocked catheter (37 patients, 47%) and catheter‐bypass (18, 23%). Only 28 patients (36%) were known to district nursing services, and 14% were referred by a district nurse. Most of the remaining patients self‐referred to the ED. No patient had any documented contact with their general practitioner. In addition, 64 patients (82%) had their catheter issues addressed adequately by ED nurses or doctors, without any urology involvement. Conclusions The high morbidity of LTCs causes a considerable demand on ED services, and has heavy cost implications to the health system. Most patients had minimal community nurse support, and their catheter problems were easily dealt with by ED nurses and doctors.

    • Abstract: Objectives To investigate the effects of testosterone on cavernosal endothelial progenitor cells (EPCs) in a castrated rat model. Methods Forty‐five male Sprague–Dawley rats (12 weeks old) were divided into control, surgical castration, and castration with testosterone replacement groups. The rats were castrated under ketamine anesthesia, and testosterone was administered by daily subcutaneous injection of 3 mg/kg testosterone propionate. The corpus cavernosum was obtained after perfusion with 10 mL saline via the abdominal aorta 4 weeks later. The expression of EPC‐specific markers [CD34, Flk1, and vascular endothelial (VE)‐cadherin] was evaluated by flow cytometry analysis and immunofluorescence staining. Results CD34+/Flk1+ and CD34+/VE‐cadherin+ cells were detected in the cavernosal sinusoidal endothelial space. Flow cytometry analysis showed that CD34 and Flk1 double positive cells (EPCs) made up about 3.79% of the corpus cavernosum in normal rats. The percentage of EPC marker positive cells decreased significantly in the castration group (2.8%; p

  • Diffusion‐weighted Imaging (DWI) Predicts Upgrading of Gleason Score
           in Biopsy‐proven Low‐grade Prostate Cancers
    • Authors: Sung Yoon Park; Young Taik Oh, Dae Chul Jung, Nam Hoon Cho, Young Deuk Choi, Koon Ho Rha, Sung Joon Hong
      Abstract: Objective To analyze whether diffusion‐weighted imaging (DWI) predicts Gleason score (GS) upgrading in biopsy‐proven low‐grade prostate cancers. Patients and Methods A total of 132 patients who have biopsy‐proven low‐grade (GS< 7) prostate cancers, 3T DWI, and surgical confirmation were retrospectively included. Clinical [prostate‐specific antigen, greatest percentage of biopsy core, and percentage of positive core number] and DWI parameters [minimum apparent diffusion coefficient (ADCmin) and mean ADC (ADCmean)] were evaluated. ADCmin was measured using a region‐of‐interest of 5‐10 mm2 at the area of lowest ADC value within a cancer, while ADCmean was measured using a region‐of‐interest covering more than half of a cancer by two independent, blinded readers, respectively. Logistic regression and receiver operating‐characteristic curve analyses were performed. Results The rate of GS upgrading was 46.1% (61/132). In both univariate and multivariate analyses, ADCmin and ADCmean were persistently significant for predicting GS upgrading (p< 0.05), whereas clinical parameters were not (p> 0.05). In both readers, the area of under curve (AUC) of ADCmin was significantly greater than that of ADCmean (AUCs of reader 1, 0.760 versus 0.711, p< 0.001; AUCs of reader 2, 0.752 versus 0.714, p= 0.003). Conclusion DWI may predict GS upgrading of biopsy‐proven low‐grade prostate cancers. The use of cancer ADCmin may allow better performance than ADCmean. This article is protected by copyright.

           increased prostate specific antigen (PSA): a meta‐analysis
    • Authors: Peter Boyle; Alice Koechlin, Maria Bota, Alberto d'Onofrio, David G. Zaridze, Paul Perrin, John Fitzpatrick, Arthur L. Burnett, Mathieu Boniol
      Abstract: Objective To review and quantify the association between endogenous and exogenous testosterone and prostate specific antigen (PSA) and prostate cancer. Methods Literature searches were performed following the PRISMA guidelines. Prospective cohort studies that reported data on the associations between endogenous testosterone and prostate cancer, and placebo controlled randomised trials of testosterone replacement therapy (TRT) that reported data on PSA and/or prostate cancer cases were retained. Meta‐analyses were performed using random‐effects models with tests for publication bias and heterogeneity. Results Twenty estimates were included in a meta‐analysis which produced a summary relative risk of prostate cancer for an increase of 5 nmol/L of testosterone of 0.99 (95% CI (0.96, 1.02)) without heterogeneity (I² = 0%). Based on 26 trials, the overall difference in PSA levels following onset of use of TRT was 0.10 ng/mL (‐0.28, 0.48). Results were similar when conducting heterogeneity analyses by mode of administration, region, age at baseline, baseline testosterone, trial duration, type of patients and type of testosterone replacement therapy. The summary relative risk of prostate cancer as an adverse effect from 11 TRT trials was 0.87 (0.30; 2.50). Results were consistent across studies. Conclusions Prostate cancer appears to be unrelated to endogenous testosterone levels. Testosterone replacement therapy for symptomatic hypogonadism does not appear to increase PSA levels nor the risk of prostate cancer development. The current data are reassuring although some care is essential until multiple studies with longer follow‐up are available. This article is protected by copyright. All rights reserved.

  • Significant reduction of positive surgical margin rate following
           Laparoscopic Radical Prostatectomy by application of the modified surgical
           margin recommendations according to the International Society of
           Urological Pathology (ISUP) consensus 2009
    • Abstract: Objectives To retrospectively verify the exact margin status and analyze the location and characteristics of positive surgical margins (PSM) in radical prostatectomy patients by a central pathology review based on the consensus conference 2009 updated margin criteria from the International Society of Urological Pathology (ISUP). Patients and Methods Detailed PSM characteristics of 441 patients who underwent laparoscopic radical prostatectomy (LRP) between 1999 and 2007 were centrally reviewed with regard to location, number, Gleason score at the PSM and tumor width. Predictors of PSM and the impact of several PSM‐characteristics on clinical outcome were examined. Patient characteristics were compared by using chi square test. Differences in recurrence‐free‐survival (RFS) were analyzed with the log‐rank test and displayed by Kaplan‐Meier survival curves. Uni‐ and multivariable cox regression analysis for the prediction of RFS was performed. Results Central pathology review including the updated PSM definition according to ISUP 2009 reclassified a substantial number of patients (n=113, 26.6%). with PSM as R0. Several PSM characteristics with a higher risk for BCR were identified: Pathological stage, Gleason score and the presence of multiple PSM (HR 1.78; 95% CI 1.08‐2.96; p=0.025) were the strongest independent predictors of RFS. Further analysis replacing the location of PSM by the width categories of PSM revealed that PSM >3mm were independent predictors of RFS (HR 1.72; 95% CI 1.08‐2.72; p=0.022). Conclusions The impact of PSM following LRP for prostate cancer remains unclear. PSM in our LRP cohort inherit different characteristics and risks for BCR. A better understanding of PSM characteristics and a careful standardized pathological evaluation is needed to adequately counsel patients with respect to prognosis and adjuvant therapy following LRP.

  • Outcomes of single versus double cuff artificial urinary sphincter
           insertion in low and high risk profile male patients with severe stress
           urinary incontinence
    • Abstract: Objectives To evaluate continence and complication rates of bulbar single and distal bulbar double cuff insertion according to low and high risk for unfavorable artificial urinary sphincter outcomes. Patients and Methods 180 patients who underwent artificial urinary sphincter implantation between 2009 and 2013 were followed according to institutional standards. Patients with previous pelvic radiation therapy, open bulbar urethral or incontinence surgery (“high risk”) underwent distal bulbar double cuff (n=123), all others (“low risk”) proximal bulbar single cuff (n=57) placement. Primary and secondary endpoints consisted of continence and complication rates. Kaplan‐Meier analysis determined explantation‐free survival, Cox regression models assessed risk factors for persistent incontinence and explantation. Results Median follow‐up was 24 months. Whereas no significant difference in pad usage/objective continence was observed after single vs. double cuff insertion, superior rates of subjective/social continence and less persistent incontinence were reported by double cuff patients (all p≤0.02). Overall, device explantation (erosion, infection or mechanical failure) occured in 12.8%. While early (0.05), double cuff patients had a 5.7‐fold higher risk of device explantation in the late follow‐up (p=0.02) and significantly shorter explantation‐free‐suvival (log‐rank: 0.003). Conclusions Distal bulbar double cuff insertion in patients with a “high risk” profile (previous pelvic radiation, urtehral surgery) leads to similar objective continence, but increased explantation rates when compared to “low risk” proximal bulbar single cuff. Randomized controlled trials comparing both devices will need to differ if higher explanations rates attribute to the double cuff device or risk factors. This article is protected by copyright.

  • Optimal Management of Non‐Muscle Invasive Micropapillary Variant
           Urothelial Carcinoma: Possibility For Missed Chance at Cure'
    • Authors: Stephen B. Williams; Ashish M. Kamat
      Abstract: Bladder cancer is a common disease in the US, affecting upwards of 74,000 patients yearly 1. Micropapillary bladder carcinoma (MPBC) is a sub type variant which was described in 1994 from our institution and which has gained in recognition since then. Due to small numbers of patients, most series other than those from major cancer centers have been in the single or low double digits. We have previously reported on the relative ‘resistance’ of this variant subtype to intravesical immunotherapy and advocated for early radical cystectomy to provide optimal cancer control for our patients. This is in contrast to the undisputed clinical benefit of Bacille Calmette and Guérin (BCG) immunotherapy for patients with conventional non‐muscle invasive bladder cancer (NMIBC) in reducing not only recurrence but also progression rates. However, since some have argued that intravesical immunotherapy is an appropriate mode of therapy even for MPBC, there is potential for missed chance of cure. This article is protected by copyright.

  • Biochemical composition of urolithiasis from stone dust ‐ a matched
           pair analysis
    • Authors: Eleanor R Ray; Gill Rumsby, R D Smith
      Abstract: Objective To determine if the biochemical composition of a renal calculus can be measured from “dust” obtained during laser fragmentation. Patients and methods Pilot study set in a tertiary referral hospital between 2011‐2013. Stone dust was aspirated through the ureteroscope during lasering and a stone fragment also retrieved. Both samples were analysed by Fourier transform infrared spectroscopy. Pairs of stone (standard) and dust were compared. They were deemed to match if both were of the same pure biochemical composition or if the predominant constituent was the same in mixed compositions, as this would not alter subsequent management. Results Paired specimens were obtained from 97 ureteroscopies. The dust specimen was sufficient for analysis in 66/97(68%) cases. Of these, the composition matched that of the stone in 49/66(74%) cases. In 12/66(18%) the biochemistry differed only in the relative proportions of each constituent, whilst 5/66 (8%) showed a complete mismatch. The overall sensitivity was 51% and specificity 97%. A limitation of the study is the small number of some stone types analysed (< 5 each cystine, atazanavir, mixed uric acid/calcium oxalate). Conclusion We have demonstrated in this pilot study successful proof of principle. Further work is required initially to improve the number of sufficient dust specimens. This technique may offer an option when a stone cannot be retrieved ureteroscopically. This article is protected by copyright. All rights reserved.

      Abstract: Objectives To evaluate the ability of clinical and radiographic features to predict lymph node (pN1) disease among patients with renal cell carcinoma (RCC) undergoing nephrectomy, and to develop a preoperative risk prediction model. Patients and Methods 220 patients with preoperative computed tomography (CT) scans available for review underwent radical nephrectomy with lymph node dissection (LND) from 2000‐2010. Radiographic features were assessed by one genitourinary radiologist blinded to pN status. Associations of features with pN1 disease were evaluated using logistic regression to develop predictive models. Model performance was assessed using AUC and decision curve analysis. Results Median lymph node yield was 10 (IQR 5‐18). Fifty‐five (25%) patients had pN1 disease at nephrectomy. On univariable analysis, maximum lymph node (LN) short axis diameter (OR 1.17; p

  • A prospective study of the short‐term quality of life outcomes of
           patients undergoing transperineal prostate biopsy
    • Authors: Adam S. Dowrick; Addie C. Wootten, Nicholas Howard, Justin S. Peters, Declan G. Murphy
      Abstract: A prospective, observational study to investigate whether transperineal prostate biopsy (TPbx) results in patient‐reported quality of life changes from baseline in the first three‐months after the procedure. Patients and methods Consenting patients completed the Expanded Prostate cancer Index Composite (EPIC‐26), the Sexual Health Inventory for Men (SHIM), the International Prostate Symptom Score (IPSS), the Generalised Anxiety Disorder (GAD‐7), the Patient Health Questionnaire (PHQ‐9) and a global question about willingness to have a repeat TPbx in a years’ time. The instruments were scored using published scoring methods. Wilcoxon signed ranks tests and Mann‐Whitney U tests were used to investigate statistically significant differences. Clinically significant differences were also investigated defined by published minimal important differences for the EPIC and changes in established categorical groups for the other instruments. Results Fifty‐three participants consented to participate and completed the baseline questionnaire in addition to at least one of the 1‐ or 3‐month follow‐up questionnaires. We found that most patients having a TPbx had no clinically significant change in quality of life in the first three months following the procedure. However, 24% exhibited clinically worse urinary function and 18% had worse sexual function at one‐month. At three‐months, 3% of patients had clinically worse urinary function and 25% continued to have worse sexual function compared with baseline. Patients who were subsequently diagnosed with cancer on the basis of the results of the TPbx exhibited statistically significantly reduced quality of life for the EPIC urinary scales and reduced improvements in scores on the psychological scales at one‐month follow‐up compared with those who were not diagnosed with cancer. Conclusions Most patients having a TPbx had no clinically significant change in quality of life in the first three months following the procedure. However, patients should be advised that a quarter may have clinically worse urinary function and nearly 20% have clinically worse sexual function in the first month and that sexual function deficits may continue up to three‐months. The results of this study provide a resource that the clinician can use when discussing TPbx with patients. This article is protected by copyright. All rights reserved.

  • The impact of the 2005 International Society of Urological Pathology
           consensus guidelines on Gleason grading – a matched pair analysis
    • Abstract: Objectives To investigate whether the International Society of Urological Pathology (ISUP) 2005 revision of the Gleason grading system has influenced the risk of biochemical recurrence (BR) after radical prostatectomy (RP), as the new guideline implies that some prostate cancers (PCa) previously graded as Gleason score (GS) 6 (3+3) are now considered as GS 7 (3+4). Patients and methods A matched pair analysis was conducted. Two‐hundred‐and‐fifteen patients with GS 6 or GS 7 (3+4) PCa on biopsies who underwent RP prior to December 31st, 2005 (pre‐ISUP group), were matched 1:1 by biopsy GS, clinical tumour category, PSA, and margin status to patients undergoing RP between January 1st, 2008 and December 31st, 2011 (post‐ISUP group). Patients were followed until BR defined as PSA ≥0.2 ng/ml. Risk of BR was analysed in a competing risk model. Results Median follow‐up was 9.5 years in the pre‐ISUP group and 4.8 years in the post‐ISUP group. The 5‐year cumulative incidences of BR were 34.0% and 13.9% (p

           Bladder inhibits cellular malignancy by antagonizing Notch1
    • Authors: Chao Zhang; Xin Ma, Jun Du, Zhiyong Yao, Taoping Shi, Qing Ai, Xusheng Chen, Zhenting Zhang, Xu Zhang, Xin Yao
      Abstract: Objective To explore the relation between miR‐30a and Notch1 and to evaluate the potential prognostic role of miR‐30a in invasive urothelial carcinoma of bladder (UCB). Patients and methods Fifty invasive urothelial carcinoma of bladder (UCB) tissue specimens, along with the adjacent bladder tissue specimens were obtained and clinical parameters of the fifty patients were analyzed. Bioinformatics analysis was performed and microRNA‐30a (miRNA‐30a/ miR‐30a) was selected as a potential miRNA targeting Notch1 and luciferase assay was performed to verify the binding site between miR‐30a and Notch1. Quantitative real‐time PCR (qRT‐PCR) was conducted to assess the RNA expressions of miR‐30a and Notch1, while western blotting and immunohistochemical staining were carried out to assess the protein expression of Notch1. Finally, cell proliferation, cell cycle, cell migration and invasion assays were conducted to evaluate the cellular effects of miR‐30a and Notch1 on UCB cell lines T24 and 5637. Results MiR‐30a was downregulated in tumour tissues when compared with adjacent bladder tissues (P

      Abstract: Objective To analyze ambulatory movements and team dynamics during robot‐assisted surgery (RAS), and investigate whether congestion of the physical space associated with RA technology led to workflow challenges, or predisposed to errors and adverse events. Methods With IRB approval, we retrospectively reviewed 10 recorded RA radical prostatectomies in a single operating room (OR). OR was divided into 8 zones, and all movement were tracked and described in terms of start and end zones, duration, personnel, and purpose. Movement were further classified into avoidable (can be eliminated/improved) and unavoidable (necessary for completion of the procedure). Results Mean operative time was 166 minutes, of which ambulation constituted 27 minutes (16%). A total of 2,896 ambulatory movements were identified (mean=290 ambulatory movements/procedure). Most of movements were procedure‐related (31%), and were performed by the circulating nurse. We identified 11 main pathways in the OR (Figure 1); the heaviest traffic was between the Circulating Nurse Zone, Transit Zone and Supply‐1 Zone.Fifty percent of ambulatory movements were found to be avoidable. Conclusion More than half of the movements during RAS can be eliminated with an improved OR setting. More studies are needed to design an evidence‐based OR layout that enhances access, workflow and patient safety. This article is protected by copyright. All rights reserved.

  • Plasma fibrinogen level: An independent prognostic factor for
           disease‐free survival and cancer‐specific survival in patients
           with localized renal cell carcinoma
    • Authors: Jun Obata; Nobuyuki Tanaka, Ryuichi Mizuno, Kent Kanao, Shuji Mikami, Kazuhiro Matsumoto, Takeo Kosaka, Eiji Kikuchi, Masahiro Jinzaki, Mototsugu Oya
      Abstract: Objectives To investigate the impact of perioperative plasma fibrinogen level as a biomarker of oncological outcome in localized renal cell carcinoma (RCC). Methods We consecutively identified 601 localized RCC patients who underwent curative surgery at a single institution. Subsequent disease recurrence and cancer‐specific survival were assessed using the Kaplan–Meier method. To evaluate the independent prognostic impact of plasma fibrinogen level, multivariate analysis was performed for these outcomes. Results Using the defined cut‐off level of preoperative plasma fibrinogen ≥420 mg/dL as elevated, we found 56 patients (9.3%) with an elevated plasma fibrinogen level preoperatively. In Kaplan–Meier analysis, there was a significant difference in disease‐free and cancer‐specific survival rates between patients with and without preoperative plasma fibrinogen levels ≥420 mg/dL. Multivariate analysis showed that elevated preoperative plasma fibrinogen level was an independent predictor of subsequent disease recurrence and cancer‐specific mortality. In a subgroup analysis of the elevated preoperative plasma fibrinogen level group, postoperative normalization of plasma fibrinogen level was significantly associated with cancer‐specific survival, showing that patients with non‐normalized plasma fibrinogen levels tended to have a higher incidence of cancer‐specific mortality after surgery. Conclusion Patients with elevated preoperative plasma fibrinogen levels could be significantly predicted to have subsequent tumor metastasis and cancer‐specific mortality, while there was a significant difference in cancer‐specific survival between patients in the normalized and non‐normalized postoperative plasma fibrinogen groups. While these are hypothesis generating results, plasma fibrinogen levels may be a useful biomarker, due to its low cost and ease of assessment. This article is protected by copyright.

  • Phase II Trial of Docetaxel, Bevacizumab, Lenalidomide, and Prednisone in
           Patients With Metastatic Castration‐Resistant Prostate Cancer
    • Abstract: Objective To determine the safety and clinical efficacy of two anti‐angiogenic agents, bevacizumab and lenalidomide, with docetaxel and prednisone. Preclinical data have demonstrated the importance of angiogenesis in prostate cancer, but previous clinical trials using angiogenesis inhibitors in combination with docetaxel have not established clinical benefit. The use of multiple anti‐angiogenic therapies together may suppress resistance mechanisms and optimize this therapeutic strategy. Subjects and Methods Eligible patients with metastatic castration‐resistant prostate cancer enrolled in this open label, phase II study of lenalidomide with bevacizumab (15 mg/kg), docetaxel (75 mg/m2) and prednisone (10mg daily). Docetaxel and bevacizumab were administered on day 1 of a 3‐week treatment cycle. To establish safety, lenalidomide dosing in this combination was escalated in a conventional 3+3 design (15, 20 and 25mg daily for two weeks followed by one week off). Patients received supportive measures including prophylactic pegfilgrastim and enoxaparin. The primary objectives were safety and clinical efficacy. Results Sixty‐three patients enrolled in this trial. Toxicities were manageable with most common adverse events being hematologic ascertained by weekly blood counts. Twenty‐nine patients (46%) had grade 4 neutropenia, 20 (32%) had grade 3 anemia and 7 (11%) had grade 3 thrombocytopenia. Despite frequent neutropenia, serious infections were rare. Other common non‐hematologic grade 3 adverse events include fatigue (10%) and diarrhea (10%). Grade 2 adverse events in >10% of patients included anorexia, weight loss, constipation, osteonecrosis of the jaw, rash and dyspnea. Of 61 evaluable patients, 57 (93%), 55(90%), and 33(54%) had PSA declines >30%, >50%, and >90% respectively. Twenty‐four of 29 patients (86%) had a confirmed radiographic partial response. The median time to progression and overall survival were 18.2 and 24.6 months, respectively. Conclusion With appropriate supportive measures, combination angiogenesis inhibition can be safely administered and potentially provide clinical benefit. This hypothesis generating data would require randomized trials to confirm these findings. This article is protected by copyright. All rights reserved.

  • Accurately Determining Patients Who Underwent Robot‐Assisted
           Surgery: Limitations Of Administrative Databases
    • Abstract: The comparative effectiveness of open vs. robot‐assisted radical prostatectomy for prostate cancer remains a controversial debate in urology. Its evaluation has largely relied on observational studies using administrative claims. In this report, we compare the accuracy of ICD‐9 procedure codes vs. an itemized charge description methodology before and after the introduction of an ICD‐9 code specifically identifying RARP in October 2008. We find that prior to 2008, charge description and ICD‐9 procedures codes were poorly correlated, whereas after 2008, they were highly correlated. These findings call for a cautious interpretation of comparative effectiveness studies of ORP vs. RARP relying on ICD‐9 procedures codes, particularly before October 2008.

  • Hypospadias Repair with Onlay Preputial Graft: A 25‐year experience
           with long‐term follow‐up
    • Authors: Gina M. Cambareri; Michael Yap, George W. Kaplan
      Abstract: Objective To evaluate the long‐term outcomes of hypospadias repair utilizing an onlay preputial graft. Material and Methods Patient records from 1989‐2013 were retrospectively reviewed. A single surgeon performed all cases and surgical technique was the same for all patients. Results There were 62 patients in the cohort and average follow‐up was 47.4 (range 1‐185) months. The meatal location was separated into distal (1 patient), midshaft (19) and proximal (42). A total of 22 (35.5%) patients experienced complications. There were three main types of complications, including meatal stenosis in 3 (4.8%), stricture in 3 (4.8%) and fistula in 21 (33.9%). The average timing of presentation with a complication after surgery was 24.9 (range 1‐127) months. 54.5% of the patients with complications presented 12 months or more after the initial surgery and 31.8% of the patients with complications presented 3 or more years from the surgical date. On univariable analysis age at the time of surgery, length of the graft, presence of chordee or meatal location (proximal or midshaft) did not predict a complication. The width of the graft was associated with a complication, with each 1 mm increase in width decreasing the odds of a complication by 56%. On multivariable analysis width remained statistically significant (OR 0.44, 95%CI 0.230‐0.840, p=0.013) for predicting a complication. Conclusion Hypospadias repair with onlay preputial graft is an option for single stage repair, especially in cases of proximal hypospadias or where the urethral plate width and/or the glanular groove is insufficient for other types of repair. Compared to flaps, the use of grafts may decrease the risk of penile torsion and prevent less bulk around the urethra, improving skin and glans closure. This article is protected by copyright.

  • The incidence and sequela of lymphocele formation after
           robot‐assisted extended pelvic lymph node dissection
    • Abstract: Objective To reveal an accurate incidence of lymphocele formation and its sequela following robot‐assisted radical prostatectomy and extended lymph node dissection (eLND) in a contemporary prostate cancer cohort. Patients and Method Consecutive patients who underwent radical prostatectomy and eLND with robot‐assistance and had a minimum follow‐up of 3 months were included. All surgeries were performed by one surgeon through a transperitoneal approach, with patients uniformly receiving low molecular weight heparin. Patients were followed with serial ultrasound imagings based on a predetermined schedule for lymphocele surveillance. Incidence and sequela of lymphoceles were retrospectively assessed. Results A total of 521 patients were analyzed. Follow‐up after surgery was 33.5 ± 22.8 months. Lymphocele developed in 9% and became symptomatic in 2.5%. All except one were detected on 1st month imaging; however, 76% regressed at 3‐month ultrasound. If lymphocele persisted at 3 months, 64% developed symptoms associated with infection and required drainage. Having diabetes mellitus was significantly associated with a higher risk of developing infected lymphocele. Other symptoms related to lymphocele were rare. Comparisons of patient characteristics between patients with and without lymphoceles did not demonstrate any significant prognostic indicators to predict the occurrence of lymphocele in neither univariate nor multivariate analysis in the present cohort. Conclusion The incidence of symptomatic lymphocele after robot‐assisted transperitoneal radical prostatectomy and eLND is rare. Obtaining an US imaging at 3 months after surgery seems feasible. Once a lymphocele is detected on 3 monthly US, discussing percutaneous external drainage with the patient appears to be wise, since it may prevent the development of symptomatic lymphocele in 2/3 of the patients.

  • Percutaneous Nephrolithotomy for Staghorn Stones: A Randomized Trial
           Comparing High Power Holmium Laser versus Ultrasonic Lithotripsy
    • Abstract: Objective To compare high power holmium Laser lithotripsy (HP‐HLL) and ultrasonic lithotripsy (US‐L) in disintegration of staghorn stones during percutaneous nephrolithotomy (PNL). Patients and Methods A non‐inferiority randomized controlled trial was conducted between August 2011 and September 2014. Inclusion criteria were patients’ age >18 years who had complete staghorn stones (branching to the three major calyces) without contraindications to PNL. Eligible patients were randomized between 2 groups (HP‐HLL and US‐L). A Standard PNL in prone position was performed for all patients. The only difference between treatment groups was method of stone disintegration. In the first group, Laser power of 40‐60 Watt (2 Joules, 20‐30 Hertz) was used to pulverize the staghorn stone into very small fragments that can pass through the Amplatz sheath with the irrigation fluid. Ultrasonic lithotripsy with suction of the fragments was used in the second group. The primary outcome (stone‐free rate) was evaluated with non‐contrast CT after 3 months. Secondary outcomes; complication, blood transfusion, operative time and haemoglobin deficit were compared. Outcome assessor was blinded to the treatment arm. Results The study included 70 patients (35 in each group). The base line characters (age, sex, BMI, side, stone volume and density) and operative technique (number, size of tracts and need for second PNL session) were comparable for both groups. Operative time was significantly shorter in US‐L (130+34 versus 148.7+35 minutes, P=0.028). Mean hemoglobin deficit was significantly more with US‐L (1.7+0.9 versus 1.3+0.6, P=0.037). The differences in blood transfusion (17% in US‐L versus 11% for HP‐HLL) and the complication rates (34% US‐L versus 23% HP‐HLL) were not significant (P=0.495 and 0.290 respectively). The stone‐free rates at 3 months were comparable (60% for US‐L and 66% for HPL‐L, P=0.621). Conclusions Compared with US‐L for intracorporeal lithotripsy of staghorn stone during PNL, HP‐HLL showed comparable safety and efficacy with lower hemoglobin deficit but longer operative time.

  • Initial experience of an algorithm‐based protocol for the community
           follow‐up of men with prostate cancer
    • Authors: Philip P Goodall; Jessica Little, Eleanor Robinson, Ian Trimble, Owen J Cole, Thomas J Walton
      Abstract: Objectives To evaluate the implementation of a novel algorithm‐based discharge programme for the community follow‐up of men with prostate cancer. Patients and methods Men with prostate cancer considered suitable for discharge were identified from consultant‐led and clinical nurse specialist telephone clinics at Nottingham University Hospitals NHS Trust. Patients were discharged on to one of four discharge pathways: watchful waiting, androgen deprivation therapy (ADT), post‐prostatectomy and post‐radiotherapy. Primary care providers were asked to adhere to specific surveillance measures and refer patients back to secondary care following breach of pre‐defined PSA threshold criteria. Reasons for non‐compliance, re‐referral and cause of death were determined for all discharged men. Findings 573 men were discharged across all four pathways; 169 on the watchful waiting pathway, 229 on the ADT pathway, 95 on the post‐prostatectomy and 80 on the post‐radiotherapy pathway. All patients had a minimum 12 months follow‐up. 48 of 54 (88.9%) of men were re‐referred promptly following PSA‐threshold breach. Of the remaining six patients there were three refusals, one unrelated death prior to referral and two late referrals at four months. Three patients were lost to follow‐up due to database non‐registration and were subsequently recalled, none of whom with a PSA‐threshold breach. There were three unexpected deaths attributed to prostate cancer: two were community deaths with no biochemical or clinical evidence of prostate cancer progression; one was due to a likely progressive PSA non‐secreting tumour. Interpretation Initial results suggest the algorithm‐based protocol is a viable, effective and oncologically safe method for the controlled discharge of men from secondary to primary care. Longer‐term follow‐up, patient satisfaction and cost‐effectiveness data are required to assess the true impact of the initiative. This article is protected by copyright. All rights reserved.

    • Authors: Newaj Abdullah; Haider Rahbar, Ravi Barod, Deepansh Dalela, Jeff Larson, Michael Johnson, Alon Mass, Homayoun Zargar, Mohamad Allaf, Sam Bhayani, Michael Stifelman, Jihad Kaouk, Craig Rogers
      Abstract: Objective To evaluate the outcomes of RPN after major prior abdominal surgery (PAS) using a large multicenter database. Methods We identified 1686 RPN from five academic centers between 2006 and 2014. A total of 216 patients had previously undergone major PAS, defined as having an open upper midline/ipsilateral incision. Perioperative outcomes were compared to the 1470 patients who had no major PAS. The Chi squared test and Mann Whitney U test were used for categorical and continuous variables, respectively. Results There was no statistically significant difference in Charlson comorbidity index, tumor size, RENAL score or pre‐operative estimated glomerular filtration rate (eGFR) between the groups. Age and body mass index (BMI) were higher in patients with PAS. The prior abdominal surgery group had a higher EBL but this did not lead to a higher transfusion rate. A retroperitoneal approach was utilized more often in patients with major PAS (11.2% vs. 5.4%), although this group did not have a higher percentage of posterior tumors (38.8% vs. 43.3%, p =0.286) Operative time, warm ischemia time, length of stay, positive surgical margin, percent change in eGFR and perioperative complications were not significantly different between the two groups. Conclusions Robotic partial nephrectomy in patients with major PAS is safe and feasible with increased EBL but no increased rate of transfusion. Patients with major PAS had almost twice the likelihood of having a retroperitoneal approach. This article is protected by copyright. All rights reserved.

  • Do stones still kill' An analysis of death from stone disease 1999 to
           2013 in England and Wales
    • Authors: Francesca Kum; Wasim Mahmalji, Jemma Hale, Kay Thomas, Matthew Bultitude, Jonathan Glass
      Abstract: Objective To analyse the trends in the number of deaths attributable to urolithiasis in England and Wales over the past 15 years (1999‐2003). Introduction Urolithiasis has an estimated lifetime risk of 12% in males and 6% in females. It is not perceived as a life‐threatening pathology. Admissions with urinary calculi contribute to 0.5% of all inpatient hospital stays. The number of deaths attributable to stone disease has yet to be identified and presented. Methods Office of National Statistics Data relating to causes of death from urolithiasis, coded as ICD‐10 N20‐N23, was collated and analysed for the 15 year period from 1999‐2013 in England and Wales. This data is sub‐categorised into anatomical location of calculi, age and gender. Results A total of 1954 deaths were attributed to urolithiasis from 1999‐2013 (mean 130.3 deaths/year). Of which, 141 were attributed to ureteric stones (mean 9.4 deaths/year). Calculi of the kidney and ureter accounted for 91% of all deaths secondary to urolithiasis; lower urinary tract (bladder or urethra) calculi contributed to only 7.9% of deaths. Data revealed an overall increasing trend in mortality from urolithiasis over this 15 year period with an increase of 3.8 deaths/year based on a linear trend (R2 0.65). Overall, the number of deaths in females was significantly higher than in males, (ratio 1.5:1, P

  • Prevalence of the HOXB13 G84E mutation in Danish men treated by radical
           prostatectomy and correlations with prostate cancer risk and
           aggressiveness
    • Abstract: Objective To determine the prevalence of the HOXB13 G84E mutation (rs138213197) in Danish men with/without prostate cancer (PC) and to investigate possible correlations between HOXB13 mutation status and clinicopathological parameters associated with tumor aggressiveness. Materials and methods Case‐control study including 995 men with PC (cases) who underwent radical prostatectomy (RP) between 1997 and 2011 at the Department of Urology, Aarhus University Hospital, Denmark. As controls, we used 1622 healthy male controls with normal prostate specific antigen (PSA) level. Results The HOXB13 G84E mutation was identified in 0.49% of controls and in 2.51% of PC cases. The mutation was associated with a 5.12‐fold increased relative risk of PC (95% confidence interval [CI]=2.26‐13.38; p=13×10‐6). Furthermore, carriers of the risk allele were significantly more likely to have a higher PSA level at diagnosis (mean 19.9 vs. 13.6 ng/ml; p=0.032), pathological Gleason score ≥7 (83.3% vs. 60.9%; p =0.032), and positive surgical margins (56.0% vs. 28.5%; p=0.006) than non‐carriers. Risk allele carriers were also more likely to have aggressive disease (54.2% vs. 28.6%; p=0.011), as defined by preoperative PSA ≥20 ng/ml, pathological Gleason score ≥ (4+3) and/or presence of regional/distant disease. At 70 months mean follow‐up, we found no significant association between HOXB13 mutation status and biochemical recurrence in this RP cohort. Conclusion This is the first study to investigate the HOXB13 G84E mutation in Danish males. The mutation was detected in 0.49% of controls and in 2.51% of cases, and was associated with 5.12‐fold increased relative risk of being diagnosed with PC. In our RP cohort, HOXB13 mutation carriers were more likely to develop aggressive PC. Further studies are needed to assess the potential of HOXB13 for future targeted screening approaches.

  • Oncologic and functional outcomes one year after radical prostatectomy for
           very low risk prostate cancer. Results from the prospective LAPPRO trial
    • Abstract: Objectives To analyse oncological and functional outcomes 12 months after treatment of very low risk prostate cancer with radical prostatectomy in men who could have been candidates for active surveillance. Patients and Methods A prospective study of all men with very low risk prostate cancer who underwent radical prostatectomy at 14 participating centres. Validated patient questionnaires were collected at base line and after 12 months by independent health‐care researchers. Biochemical recurrence (BCR) was defined as PSA ≥ 0.25 ng/ml or treatment with salvage radiotherapy or treated with hormones. Urinary continence was defined as “less than one pad changed per 24 hour”. Erectile function was defined as “erection hard enough for penetration more than half of the time after sexual stimulation”. Changes in tumor grade and stage were obtained from pathology reports. We show descriptive frequencies and proportions having each outcome in various subgroups. Fisher's exact test was used to assess differences between the age groups. Results Of the 4003 men in the LAPPRO cohort, 338 men fulfilled the preoperative national criteria for very low risk prostate cancer. Adverse pathology outcomes included: upgrading, defined as pT3 or postoperative Gleason sum ≥ 7, was present in 35% (115/333), positive surgical margins, 16% (54/329). Only 7/329 men (2.1%) had PSA concentration > 0.1 ng/ml 6‐12 weeks postoperatively. Erectile function and urinary continence were 44% (98/222) and 84% (264/315) 12 months postoperatively. Trifecta defined as preoperative potent and continent men that remained potent and continent with no BCR was at 12 months 38% (84/221). Conclusions Our prospective study of men with very low risk prostate cancer undergoing open or robotic radical prostatectomy showed favourable oncological outcome in about two‐thirds. About 40 per cent did not suffer from surgically induced urinary incontinence or erectile dysfunction 12 months postoperatively. These results provide additional support for the use of active surveillance in men with very low risk prostate cancer, however the group of men with risk of upgrading and upstaging is not negligible. Improved stratification is still an urgently needed. This article is protected by copyright. All rights reserved.

    • Authors: Ahmed A. Hussein; Somayeh B. Shafiei, Mohamed Sharif, Ehsan Esfahani, Basel Ahmad, Justen D. Kozlowski, Zishan Hashmi, Khurshid A. Guru
      Abstract: Objective To investigate the role of cognitive and mental workload assessment may play a critical role in defining successful mentorship Materials and Methods “Mind Maps” project aims at evaluating cognitive function of surgeon's expertise and trainee's skills. The study included electroencephalogram (EEG) recordings of the mentor observing trainee surgeons in 20 procedures during extended lymph node dissection (e‐LND) and urethro‐vesical anastomosis (UVA), with simultaneous assessment of trainees using NASA‐TLX questionnaire. We also compared the brain activity of the mentor during this study to his own brain activity while actually performing the same surgical steps from previous procedures populated in the “Mind Maps” project.. Results During LND and UVA, when the mentor thought the trainee's mental demand and effort were low based on his NASA‐TLX (not satisfied with his performance), his EEG‐based mental workload increased (reflecting more concern and attention). The mentor was mentally engaged and concerned while he was engrossed in observing the surgery. This was further supported by the finding that there was no significant difference in the mental demands and workload between observing and operating for the expert surgeon. Conclusion This study objectively evaluated cognitive engagement of a surgical mentor teaching technical skills during surgery. Our study provides a deeper understanding of how surgical teaching actually works and opens new horizons for assessment and teaching of surgery. Further research is needed to study the feasibility of this novel concept in assessment and guidance of surgical performance. This article is protected by copyright. All rights reserved.

    • Authors: E R Jefferies; A Bahl, L Hounsome, M F Eylert, J Verne, R A Persad,
      Abstract: Objective To investigate the relationship effect of androgen deprivation therapy (ADT) and fracture in men in the UK. Patients and Methods Using the Hospital Episodes Statistics (HES) database for years 2004 to 2008 that contains all the information about NHS and NHS‐funded hospital admissions in England ‐ 8,902 patients were found to have had prostate cancer and an admission to hospital with a fracture in 2004 to 2008. Of these 3,372 (37.8%) were flagged as being treated with ADT, whilst there were 5,530 (62.2%) admissions in the non ADT group (table 1). There were a total number of 228,852 admissions in the background population. Results The risk of a fracture requiring hospitalisation increases from 1.12 to 1.41 per 100 person years when a man is treated with ADT with prostate cancer than without – an absolute increase of only 0.29 per 100 person years. When compared to the background population, there is an increase from 0.58 per 100 person years in the background population to 1.41 – a relative rate ratio increase of 2.4 (p

  • The role of targeted prophylactic antimicrobial therapy prior to
           transrectal ultrasound (TRUS) guided prostate biopsy in reducing infection
           rates: a systematic review
    • Authors: A Cussans; B K Somani, A Basarab, T Dudderidge
      Abstract: Objective To compare the incidence of infective complications following transrectal ultrasound‐guided (TRUS) biopsy with either empirical fluoroquinolone or culture‐based targeted antimicrobial prophylaxis, and the prevalence of fluoroquinolone resistance in men undergoing prostate biopsy. Materials and methods A systematic review of the literature was performed following PRISMA guidelines. We included studies of patients undergoing TRUS biopsy that compared infective outcomes of those who received targeted antimicrobial therapy based on the results of pre‐procedural rectal swab cultures, with those receiving empiric fluoroquinolone antimicrobial prophylaxis. The prevalence of fluoroquinolone resistance was recorded as a secondary outcome measure. Studies with no control group were excluded. Results From 125 studies screened, 9 studies (4571 patients) met the inclusion criteria [1‐9]. All studies were of cohort design, and included a combination of retrospective and prospective data. Six studies included were undertaken in North America [1‐4, 8, 9]. The remaining were undertaken in Spain [5], Turkey [6] and Columbia [7]. Within these studies, 2484 (54.3%) patients received empirical fluoroquinolone prophylaxis whilst 2087 (45.7%) patients had pre‐biopsy rectal swabs and targeted antibiotics. Mean fluoroquinolone resistance was 22.8%. Post biopsy infection and sepsis rates were significantly higher in groups given empirical prophylaxis (4.55%, 2.21%) compared with groups receiving targeted antibiotics (0.72%, 0.48%). Based on these results 27 men would need to receive targeted antibiotics to prevent one infective complication. Conclusion Our systematic review suggests that targeted prophylactic antimicrobial therapy prior to TRUS guided prostate biopsy is associated with lower rates of sepsis. We therefore recommend changing current pathways to adopt this measure. This article is protected by copyright. All rights reserved.

    • Authors: C Poullis; M Shabbir, I Eardley, J Mulhall, S Minhas
      Abstract: Peyronie's disease was described by Francois de la Peyronie in 1743, a battlefield surgeon and Commander of the Medical Corps of Louis XIV. The prevalence in the general population varies from 0.39‐3.4%, but increases to 7.1% in patients between 50‐69 years of age, with a reported prevalence rate of 20.3% in men with diabetes. The disease has two distinct clinical phases; the acute and stable or chronic phases. The acute phase is characterised by painful erections with increasing penile deformity usually lasting between 3‐12 months. The chronic phase is usually pain‐free and characterised by stabilisation of the plaque and penile deformity. The aetio‐pathogenesis of the disease remains largely unknown with local trauma, genetic and vascular factors being implicated. This article is protected by copyright. All rights reserved.

  • Urethral fixation technique improves early urinary continence recovery in
           patients who underwent Retropubic Radical Prostatectomy
    • Abstract: Objectives to describe step by step an original urethra‐vesical anastomosis technique (Urethral fixation) in patients who underwent retropubic radical prostatectomy (RRP) and compare the observed early urinary continence recovery rates with those reported in a control group receiving a standard anastomosis technique. Moreover, we identified the predictors of early urinary continence recovery. Patients and methods We compared 70 patients who underwent RRP with urethral fixation technique with a contemporary control group of 51 patients who received RRP with a standard urethra‐vesical anastomosis. In the study group, the urethra‐vesical anastomosis was performed using 8 single stitches. Specifically, to avoid retraction and/or deviations we fixed the urethral stump laterally to the medial portion of levator ani muscle. Moreover, to maintain the normal position in the context of pelvic floor we fixed the urethra sphincter deeper to the medial dorsal rafe using a 3‐0 PDS stitch at 6 o'clock before completing the incision of the urethral wall. Urinary continence recovery was evaluated 1 week, 1, 2 and 3 months after catheter removal. Patients self‐reporting no urine leak were considered continent. Univariable and multivariable analyses were used to identify predictors of urinary incontinence at different follow‐ups. Results The two evaluated groups resulted comparable for all the pre‐operative variables. One week after catheter removal, 32 (45.7%) patients in the study group and 10 (19.6%) in the control group were continents (p=0.01), respectively. Similarly, 1 month after catheter removal, 46 (65.7%) patients in the urethral fixation group and 16 (31.4%) declared to be continent (p=0.001), respectively. Two months after catheter removal, 59 (84.3%) patients in the study group and 21 (41.2%) in the control group were continents (p

    • Abstract: Objective to determine the association among PCA3 score, Prostate Imaging Reporting and Data System (PI‐RADS) and Gleason Score (GS), in a cohort of patients with elevated PSA, undergoing MRI/US fusion software‐based targeted prostate biopsy (TBx) after a previous negative randomized “standard” biopsy (SBx) Patients and Methods 282 patients, undergone to TBx after previous negative SBx and PCA3 urine assay, were enrolled. The associations PCA3 score/PI‐RADS and PCA3 score/GS were investigated by K‐means clustering, ROC analysis and binary logistic regression model Results PCA3 score difference for negative versus positive TBx cohorts was highly statistically significant. One unit of increase in PCA3 score was associated to a 2.4% increased risk to have a positive TBx result. PCA3 score>80 and PI‐RADS≥4 were independent predictors for a positive TBx. The association between PCA3 score and PI‐RADS was statistically significant (PCA3 score median value for PI‐RADS groups 3‐4‐5 was 58‐104‐146, respectively; p=0.006). A similar pattern was detected for the relationship between PCA3 score and GS; an increasing PCA3 score was associated to a worse GS (median PCA3 score equal to 62‐105‐132‐153‐203‐322 for GS 3+4, 4+3, 4+4, 4+5, 5+4, 5+5, respectively; p

  • Recent advances in immuno‐oncology and the application to urological
           cancers
    • Abstract: Recent advances in immuno‐oncology have the potential to transform the practice of medical oncology. Antibodies directed against negative regulators of T cell function (checkpoint inhibitors), engineered cell therapies, and innate immune stimulators such as oncolytic viruses are effective in a wide range of cancers. Immune‐based therapies have had a clinically meaningful impact on the treatment of advanced melanoma and the lessons regarding use of single agents and combinations in melanoma may be applicable to the treatment of urological cancers Checkpoint inhibitors, cytokine therapy and therapeutic vaccines are already showing promise in urothelial bladder cancer, renal cell carcinoma and prostate cancer. Critical areas of future immuno‐oncology research include the prospective identification of patients who will respond to current immune‐based cancer therapies, and the identification of new therapeutic agents that promote immune priming in tumors, and increase the rate of durable clinical responses.

  • Robot‐assisted Fallopian Tube Transection‐anastomosis using
           the New REVO‐I Robotic Surgical System: Feasibility in a Chronic
           Porcine study
    • Abstract: Objectives Fallopian tube anastomosis is used for basic robotic training (Intuitive Surgical) because it emphasizes the unique advantages of a robotic surgical system (fine motor movements required for intracorporeal suturing, 3D vision, motion scaling, and tremor control). Furthermore, fallopian tube anastomosis resembles robotic radical prostatectomy in regards to port placement, pelvic area approach, and urethrovesical anastomosis. The aim of our study was to evaluate the feasibility and safety of the new REVO‐I robotic platform by performing fallopian tube transection‐anastomosis in live porcine models. Material and Methods A prospective chronic animal study was carried out in four Crossbred female pigs. The primary outcome was assessment of the pigs’ 2‐week survival. The secondary outcomes were measurements of intraoperative parameters and the complications or difficulties when using the REVO‐I. Results Fallopian tube anastomosis was successfully performed in 4 porcine models. The mean operative time was 66 min (range: 46‐104 min), the mean docking time was 22.25 min (range: 14–53 min), and the mean console time was 18 min (range: 13–20 min). The REVO‐I robotic system functioned appropriately, with no technical problems or difficulties noted during the procedures. Both the surgeon and the bed‐side assistants reported ease of use and better performance with subsequent procedures. All pigs were alive 2 weeks after surgery, with no perioperative complications related to the use of the robot. Conclusions The current pre‐clinical chronic animal study revealed that the REVO‐I robotic surgical system is a feasible and safe robotic instrument that can be used by surgeons to perform skillful robotic procedures in porcine models. Our next objective is to demonstrate its safety in humans. This article is protected by copyright. All rights reserved.
       
  • Testosterone Undecanoate improves Sexual Function in Men with Type 2
           diabetes and Severe Hypogonadism: Results from a 30 week randomized
           placebo controlled study
    • Abstract: Objective To evaluate the Sexual Function response to 30 weeks treatment with Long Acting Testosterone Undecanoate (TU) or Placebo (P) 199 men with type 2 diabetes and either severe or mild hypogonadism. Patients and Methods Men with hypogonadism (HG) were identified from 7 primary care T2DM registers. A 30 week randomised placebo controlled study of TU was carried out in 199 of these men (P: 107, TU: 92). The patient reported outcome measure was the IIEF ‐15. Men completing the study (n=189) were stratified firstly, by baseline total testosterone (TT) / free testosterone (FT) into Mild HG (TT 8.1–12nmol/l or FT 0.18‐0.25nmol/l) and Severe HG groups (TT ≤8nmol/l and FT ≤0.18nmol/l) and secondly by intervention (P and TU) leading to 4 groups; Mild HG/P, Mild HG/TU, Severe HG/P and Severe HG/TU. Statistical Analysis Changes in sexual function score (a secondary outcome of the study) at each visit within group (cf. baseline) and between groups (TU vs P) at each assessment (6, 18 and 30 weeks) were compared using Wilcoxon signed‐rank and Wilcoxon rank sum tests respectively. Results Significant improvement in erectile function was evident only in the Severe HG group following TU after 30 weeks, this finding also present when TU was compared to P. Intercourse satisfaction and sexual desire scores were also improved in the Severe HG group following TU at 6, 18 and 30 weeks, this increase in scores also evident when compared to P. TU did not appear to significantly alter orgasmic function in any of the patient groups. Conclusions Our study suggests that benefit in sexual symptoms following TU was evident principally in patients with HG with TT ≤8nmol/l and FT ≤0.18nmol/l. We also suggest 30 weeks of treatment is necessary before evaluating improvement in erectile function. This article is protected by copyright. All rights reserved.
       
  • Mirabegron causes relaxation of human and rat corpus cavernosum: could it

    • Abstract: Objective To examine the effects of mirabegron, a selective β3‐AR agonist that has recently been approved for the treatment of overactive bladder, in rat and human erectile tissues with a focus on elucidating the mechanism of such an action. Stimulation of β3‐adregenic receptors (ARs) localized in cavernosal smooth muscle cells may play a physiological role in mediating penile erection, and offer a beneficial pharmacologic action for the patient who has overactive bladder and erectile dysfunction (ED). Materials and Methods Corpus cavernosal (CC) specimens were obtained from patients with ED and Peyronie's disease undergoing penile prosthesis implantation. Erectile responses were also evaluated in vivo following intracavernosal injection (ICI) of mirabegron in anesthetized rats. Mirabegron‐elicited relaxation responses (10‐8‐10‐3 M) on phenylephrine (Phe)‐induced contraction were observed in human and rat CC strips in isolated organ bath studies. The effects of inhibitors namely L‐NAME [N(G)‐nitro‐L‐arginine methyl ester (a competitive inhibitor of NO synthase), 100μM), ODQ [1H‐(1,2,4) oxadiazolo(4,3‐α) quinoxalin‐1‐one (a nitric oxide‐sensitive guanylyl cyclase (GC) inhibitor, 30μM), methylene blue (a NOS and GC inhibitör, 20μM), SR59230A (β3‐AR blocker, 1 μM), and fasudil (Rho‐kinase (ROCK) inhibitor, 0.1 μM)] on mirabegron‐induced relaxation responses were evaluated. Responses to mirabegron were compared with responses to isoprenaline and nebivolol. Immunohistochemistry was used to localize β3‐AR and ROCK in CC smooth muscle cells. In vivo rat data were expressed as intracavernosal pressure (ICP)/mean arterial pressure and total ICP. Results Mirabegron resulted in a relaxation of Phe‐evoked CC contractions in a concentration‐dependent manner and SR59230A antagonized mirabegron‐induced relaxations in human and rat CC. Other inhibitors, L‐NAME, ODQ, and methylene blue, did not affect the mirabegron‐induced relaxation responses. Mirabegron relaxation responses at concentrations (between 0.1 and 10μM) were enhanced by fasudil (ROCK inhibitor) in rat but not in human CC strips. KCl‐induced contractions in human and rat CC were partially inhibited by mirabegron. In vivo ICI of mirabegron (doses of 0.1 – 1 mg/kg) had a minor effect on ICP when compared to vehicle administration. Immunohistochemistry data showed β3‐ARs localization into the smooth muscle cells of human and rat CC. Conclusions Mirabegron markedly relaxed isolated CC strips by activating β3‐ARs independently of the NO‐cGMP pathway. There is also evidence of the existence of a close functional link between β3‐ARs and the RhoA/ROCKpathway. These results may support further clinical studies using combinations of mirabegron with ROCK and phosphodiesterase‐5 inhibitors (PDE5i) for the treatment of ED, especially in patients who do not respond to PDE5i therapy.

  • Outcomes of high complex renal tumor (PADUA ≥ 10) following
           robot‐assisted partial nephrectomy with a median 46 months
           follow‐up: A tertiary center experience
    • Abstract: Objectives To compare peri‐operative trifecta achievement and long‐term oncological and functional outcomes between low (6‐7), intermediate (8‐9) and high (≥10) PADUA complex renal tumors and to determine predictors for trifecta achievement. Material and Methods A retrospective analysis of data from 295 patients, who underwent RPN between 2006 to 2015 at high‐volume tertiary center was performed. Trifecta achievement was the main primary outcome measurement. The perioperative parameters and long‐term oncological and functional outcomes were the secondary outcome measurements. Groups were compared using Kruskal‐Wallis H test or chi‐square. Univariable and multivariable binary logistic regression analyses were performed to determine the most important determinant variables associated with trifecta accomplishment. The Kaplan‐Meier method was used to estimate for overall survival (OS), cancer‐specific survival (CSS) and cancer‐free survival (CFS). Results Out of 295 patients, 121 (41%) had PADUA score ≥10. Patients in high complex PADUA group had a larger tumor size, higher clinical stage ≥T1b, an increased risk of malignancy, longer warm ischemia time (WIT) and increased estimated blood loss (EBL) compared to intermediate and low complex groups (p=
       
  • Attitudes and Knowledge of Urethral Catheters: A Targeted Educational
           Intervention
    • Abstract: Objectives To assess the training of medical students and their confidence in urethral catheter placement, given growing evidence of unnecessary urology consults and iatrogenic injury. Methods A third‐year medical school class was queried regarding their attitudes and knowledge of catheter placement prior to and after the Clinical Biennium. The Clinical Biennium introduces hands on skills prior to clinical clerkships. Urethral catheterization is one of the skill stations that students rotate through, and urology residents provide a didactic session and supervised simulation. Confidence was self‐rated regarding catheter technique, knowledge, troubleshooting, and comfort with placement in same and opposite gender. Factual questions were posed regarding proper insertion and malfunctioning catheters. Results Ninety‐two students participated in the initial survey, 41% female and 59% male. 87% of students had never placed a catheter. Students desired high confidence in catheter skills (4.4/5). There were no significant differences in responses for those with desire to pursue urology vs. other specialties, or procedural fields compared to non‐procedural fields. Prior independent learning was reported by 38% of students and was a predictor for increased confidence across all domains (p
       
  • Correlation between stage shift and differences in mortality in the
           European Randomized study of Screening for Prostate Cancer (ERSPC)
    • Abstract: A 21% prostate cancer (PCa) mortality reduction was observed in the European Randomized Study of Screening for Prostate Cancer (ERSPC) at 13 years of follow‐up. A direct correlation between stage shift and changes in PCa‐mortality would support earlier detection through screening as the main reason for this reduction. In this study we empirically estimate how changes in the risk of being diagnosed with (advanced) PCa are related to the changes in PCa death in the ERSPC using a meta‐regression approach. In total 81% and 89% of the changes in PCa mortality could be explained by changes in PCa incidence. Although this analysis cannot show direct causal relations, results support the hypothesis that PSA screening reduced PCa mortality by detecting cancer at an earlier stage while still curable. These findings do however not open the way to unrestricted PSA based screening for PCa. A balance between harm and benefit needs to be found. This article is protected by copyright.

  • Detecting Positive Surgical Margins: Utilization of Light Reflectance
           Spectroscopy on ex vivo Prostate Specimens
    • Abstract: Objective To assess the efficacy of Light reflectance spectroscopy (LRS) to detect positive surgical margins (PSM) on ex vivo radical prostatectomy specimens. Materials and Methods A prospective evaluation of ex vivo prostate specimens using LRS was performed at a single institution from June 2013 to September 2014. LRS measurements were performed on selected sites on prostate capsule, marked with ink, and correlated with pathologic analysis. Significant features on LRS curves differentiating malignant tissue from benign tissue were determined using a forward sequential selection algorithm. A logistic regression model was built and randomized cross‐validation was performed. The sensitivity, specificity, accuracy, NPV, PPV, and area under the receiver operating characteristic curve (AUC) for LRS predicting PSM were calculated. Results Fifty prostate specimens were evaluated using LRS. LRS sensitivity for Gleason ≥7 PSM was 91.3%, specificity 92.8%, accuracy 92.5%, PPV 73.2%, NPV 99.4%, and AUC = 0.960. LRS sensitivity for Gleason ≥6 PSM was 65.5%, specificity 88.1%, accuracy 83.3%, PPV 66.2%, NPV 90.7%, and AUC = 0.858. Conclusions LRS can reliably detect positive surgical margins for Gleason 7 or above prostate cancer in ex vivo radical prostate specimens This article is protected by copyright.

  • Toxicity and efficacy of salvage 11C‐Choline PET/CT‐guided
           
    • Abstract: Objective To report the 3‐year toxicity and outcome results of 11C‐Choline positron emission tomography/computed tomography (11C‐Ch‐PET/CT)‐guided radiotherapy, delivered with helical tomotherapy (Tomotherapy® Hi‐Art II® Treatment System, Accuray Incorporated, USA) (HTT) of lymph‐nodal (LN) relapses in prostate cancer patients. Patients and methods From 01/2005 to 03/2013, 81 patients with biochemical recurrence – after surgery±adjuvant/salvage radiotherapy (RT) or radical RT and with evidence of LN 11C‐Ch‐PET/CT pathological uptake underwent HTT (median PSA: 2.59(0.61‐187) ng/ml). 72/81 patients were treated on pelvic and/or lumbar‐aortic LN chain with HTT at 51.8 Gy/28 fr and with simultaneous integrated boost (SIB) to a median dose of 65.5 Gy on the pathological uptake sites detected by 11C‐Ch‐PET/CT. Nine patients were treated without SIB(50‐65.5 Gy, 25‐30 fr). Results With a median follow‐up of 36 (9‐116) months, 91.4% of the patients presented a PSA reduction 3 months after HTT. The 3 year overall, local‐relapse‐free and clinical‐relapse‐free survival were 80.0%, 89.8% and 61.8%, respectively. The 3‐year actuarial incidences of ≥G2 rectal and ≥G2 GU toxicity were 6.6% (± 2.9%) and 26.3% (±5.5%) respectively. A PSA nadir ≥0.26 ng/ml (HR:3.6; 95%CI 1.7‐7.7, p=0.001), extra‐pelvic 11C‐Ch‐PET/CT positive LN location (HR:2.4; 95%CI 0.9‐6.4, p=0.07), RT previous to HTT (HR:2.7; 95% CI 1.07‐6.9, p=0.04) and number of positive LN (HR:1.13; 95%CI 1.04‐1.22, p=0.003) were the main predictors of clinical relapse after HTT . Conclusions 11C‐Ch‐PET/CT‐guided HTT is safe and effective in the treatment of LN relapses of previously treated prostate cancer patients. This article is protected by copyright.

  • Performance of Robotic Simulated Skills Tasks is Positively Associated
           with Clinical Robotic Surgical Performance
    • Abstract: Objective To compare user performance of four Fundamental Inanimate Robotic Skills Tasks (FIRST) as well as eight da Vinci Skills Simulator (dVSS) virtual reality tasks to intraoperative performance (concurrent validity) during robotic prostatectomy (RP). Our group has previously demonstrated face, content, and construct validity of these simulated robotic skills tasks. As there is no data in the robotic environment showing a significant relationship between simulation and clinical performance, we aim to show that a positive correlation exists between simulation and intraoperative performance. Materials and Methods Twenty‐one urologic surgeons of varying robotic experience were enrolled. Demographics were captured using a standardized questionnaire. User performance was assessed concurrently in simulated (FIRST exercises and dVSS tasks) and clinical environments (endopelvic dissection during RP). Intraoperative robotic clinical performance was scored using the previously validated 6‐metric Global Evaluative Assessment of Robotic Skills (GEARS) tool. Relationship between simulator and clinical performance was evaluated using Spearman's rank correlation. Results Performance was assessed in 17 trainees and 4 expert robotic surgeons with a median (range) number of previous robotic cases (as primary surgeon) of 0 (0‐55) and 117 (58‐600), respectively (p=0.001). Collectively, the overall FIRST (ρ=0.833, p
       
  • Early MAG‐3 diuretic renography results after pyeloplasty
    • Abstract: Objectives To describe the drainage and functional outcome following paediatric pyeloplasty, one week after stent removal (seven to nine weeks after pyeloplasty) using diuretic renography. Patients and Methods Between 2009 and 2014, we assessed the functional and drainage outcomes on mercaptoacetyltriglycine (MAG‐3) diuretic renograms from 66 children (69 kidneys) who underwent modified dismembered Anderson‐Hynes pyeloplasty for UPJ obstruction. Stents were left in place for 6 to 8 weeks and postoperative renal units were evaluated with MAG‐3 renogram one week after stent removal. Surgical success was defined by improvement of drainage (T/2 less than 20 min), stable or improved function on the postoperative MAG‐3 renogram and by decreased pyelocaliceal dilatation on US at one year. Results Of the 69 kidneys with preoperative median T/2 of 33.4 min (range 7.6‐200 min), 87% (60/69) had improved drainage curves with a median T/2 of 6.9 min (range 1.6‐19 min). Thirteen percent (9/69) had persistent impaired drainage with a median T/2 of 36 min (range 24‐108 min). One girl was found with a persistent obstructive pattern (T/2= 30 min) associated with a decreased SRF (from 42 to 33%) and a persistent hydronephrosis (at 28mm). Redo‐pyeloplasty was performed 2 months after the initial procedure (and 18 days after stent removal) and renal function recovered to 47%. All other 8 patients were free of symptoms; hydronephrosis improved at 1 year (anteroposterior diameter decreased from 28 to 18.5 mm, p=1.94) and SRF remained stable (44.5% versus 48.5% after repair, p=ns). Of the 29% (20/69) that had preoperative impaired SRF, postoperative renal function improved in 75% (from 27.5 to 43%, p=0.0002), remained unchanged in 2% and one (0.2%) deteriorated. Median postoperative follow‐up was 18 months (range 12‐90 months). Discussion There is no agreement regarding the gold standard investigation to use following pyeloplasty for ureteroplevic junction (UPJ) obstruction. Improvement in hydronephrosis on ultrasound (US) is slow and often takes more than 12 months. Based on animal studies, it is possible that missed recurrent obstruction will cause irreversible loss of renal function after 6 weeks. Therefore early postoperative assessment is desirable but there have been few reports on urinary drainage changes with early diuretic renography after pyeloplasty. Conclusion Most of renal units have improved drainage on diuretic renography 7 weeks after pyeloplasty and 1 week after stent removal. An early diuretic renogram is a reliable method of documenting surgical success after pyeloplasty. This article is protected by copyright. All rights reserved.
       
  • If the robot is there, why not use it' Why we should use the robot for
           laparoscopic nephrectomy
    • Abstract: Robot‐assisted laparoscopic nephrectomy (RALN) was first described over 10 years ago [1]. However, with the wide availability of established and experienced laparoscopic surgeons, investigation into the role and potential benefits of RALN has been limited. Many consider RALN to bare no additional benefits over laparoscopic radical nephrectomy (LRN) but see it as merely expensive, and regard it as ‘technical overtreatment’. On the other hand, robotic surgery improves laparoscopic dexterity with a better range of movement, three‐dimensional vision, tremor filtration, and motion scaling leading to better eye‐hand coordination. It is a tool for complex laparoscopic surgery and is indeed a very good one, but is there a role for RALN' This article is protected by copyright. All rights reserved.
       
  • Symptomatic and quality of life outcomes following treatment for
           clinically localized prostate cancer: a systematic review
    • Abstract: Objectives To conduct a systematic review of the risks of short‐term outcomes following major treatments for clinically localized prostate cancer. Materials and methods MEDLINE, EMBASE and the Cochrane Library from 2004 to January 2013. Study arms that included at least 100 men with localized prostate cancer in receipt of surgery, radiotherapy or active surveillance and reported symptomatic and quality of life (QoL) data from 6 months to five years after treatment were eligible. Data were extracted by one reviewer and checked by another. Results 64 studies (80 treatment cohorts) were included. Most were single treatment cohorts from the US or Europe. Prostatectomy was the most common treatment (39 cohorts), followed by radiotherapy (external beam and brachytherapy; 31 cohorts), with only one active surveillance cohort. Most frequently measured symptoms were urinary, followed by sexual and bowel; QoL was assessed in only 17 cohorts. Most studies used validated measures, although poor data reporting and differences between studies meant that it was not possible to pool data. Conclusion Data on the precise impact of short‐term symptomatic and QoL outcomes following treatment for localized prostate cancer is of insufficient quality for clear guidance to men about the risks to these aspects of their lives. It is important that future studies focus on collecting core outcomes through validated measures and comply with reporting guidelines so that clear and accurate information can be derived for men considering screening or treatment for prostate cancer.

  • Results of a randomized, double‐blind, active‐controlled
           clinical trial with propiverine ER 30 mg in patients with overactive
           bladder
    • Abstract: Objective To compare the efficacy and safety of the 30 mg extended release (ER) formulation of propiverine hydrochloride with the 4 mg extended release formulation of tolterodine tartrate in patients with overactive bladder in a non‐inferiority trial. Patients and methods Eligible patients aged between 18 and 75 years with symptoms of OAB were enrolled in this multicentre, randomized, double‐blind, parallel‐group, active‐controlled study. After a 2‐week screening period patients were randomized at a 1:1 ratio to receive either propiverine ER 30 mg or tolterodine ER 4 mg daily during the 8‐weeks treatment period. The efficacy was assessed using a 3‐days voiding diary and patient's self‐reported assessment of treatment effect. Safety assessment included recording of adverse events, laboratory test results, measurement of post void residual urine, and electrocardiograms. Results A total of 324 patients (244 female, 80 male) were allocated into the study. Both active treatments improved the variables of the voiding diary and patient's self‐reported assessment. The change from baseline in the number of voidings per 24 h was significantly greater in the propiverine ER 30 mg group compared to the tolterodine ER 4 mg group after 8 weeks of treatment (FAS; ‐4.6±4.1 vs. ‐3.8±5.1, p=0.005). Significant improvements were also observed for the change of urgency incontinence episodes after 2 weeks (p=0.026) and 8 weeks (p=0.028) of treatment when comparing propiverine ER 30 mg with tolterodine ER 4 mg. Both treatments were well tolerated with a comparable frequency of adverse drug reactions between propiverine ER 30 mg and tolterodine ER 4 mg (FAS; 40.7% vs. 39.5%, p=0.8). More patients treated with tolterodine ER 4 mg discontinued the treatment due to adverse drug reactions compared to propiverine ER 30 mg (7.4% vs. 3.1%). Conclusions Propiverine ER 30 mg was confirmed to be an effective and well‐tolerated treatment option for patients suffering from overactive bladder symptoms. This first head‐to‐head study demonstrated non‐inferiority of propiverine ER 30 mg compared to tolterodine ER 4 mg. This article is protected by copyright. All rights reserved.

           without clinical benign prostatic hyperplasia: a large,
           cross‐sectional, UK epidemiological study
    • Abstract: Objectives To compare the prevalence of metabolic syndrome and the components of metabolic syndrome in men aged ≥50 years with and without clinical benign prostatic hyperplasia (BPH). Subjects and Methods This was a cross‐sectional study using the UK Clinical Practice Research Datalink (CPRD). Men were selected from the CPRD who were aged ≥50 years and still registered as of 31 December 2011. Cohort 1 included men with clinical BPH, and cohort 2 men without clinical BPH who were matched 1:1 to those in cohort 1 by general practice, year of birth and previous years of available history (1–
       
  • Transcutaneous interferential electrical stimulation for the management of
           non‐neuropathic underactive bladder in children: a randomised
           clinical trial
    • Abstract: Objectives To assess the efficacy of transcutaneous interferential electrical stimulation (IFES) and urotherapy in the management of non‐neuropathic underactive bladder (UAB) in children with voiding dysfunction. Patients and Methods In all, 36 children with UAB without neuropathic disease [15 boys, 21 girls; mean (sd) age 8.9 (2.6) years] were enrolled and then randomly allocated to two equal treatment groups comprising IFES and control groups. The control group underwent only standard urotherapy comprising diet, hydration, scheduled voiding, toilet training, and pelvic floor and abdominal muscles relaxation. Children in the IFES group likewise underwent standard urotherapy and also received IFES. Children in both groups underwent a 15‐session treatment programme twice a week. A complete voiding and bowel habit diary was completed by parents before, after treatment, and 1 year later. Bladder ultrasound and uroflowmetry/electromyography were performed before, at the end of treatment course, and at the 1‐year follow‐up. Results The mean (sd) number of voiding episodes before treatment was 2.6 (1) and 2.7 (0.76) times/day in the IFES and control groups, respectively, which significantly increased after IFES therapy in IFES group, compared with only standard urotherapy in the control group [6.3 (1.4) vs 4.7 (1.3) times/day, P < 0.002). The mean (sd) bladder capacity before treatment was 424 (123) and 463 (121) mL in the control and IFES groups, respectively, which decreased significantly at 1 year after treatment in the IFES group compared with the controls, at 227 (86) vs 344 (127) mL (P < 0.01). Maximum urine flow increased and voiding time decreased significantly in the IFES group compared with controls at the end of treatment sessions and 1 year later (P < 0.05). All the children had abnormal flow curves at the beginning of the study. The flow curve became normal in 14/18 (77%) of the children in the IFES group and six of 18 (33%) in the control group by the end of follow‐up (P < 0.007). At the end of the treatment course, night‐time wetting was improved in all children who had this symptom before the treatment in the IFES group (P < 0.01). Conclusion Combining IFES and urotherapy is a safe and effective therapy in the management of children with UAB.
       
  • Microscopic haematuria at time of diagnosis is associated with lower
           disease stage in patients with newly diagnosed bladder cancer
    • Abstract: Objectives To determine whether the severity of haematuria (microscopic or gross) at diagnosis influences the disease stage at presentation in patients diagnosed with bladder cancer. Patients and Methods We conducted a multi‐institutional observational cohort study of patients who were newly diagnosed with bladder cancer between August 1999 and May 2012. We reviewed the degree of haematuria, demographic information, clinical and social history, imaging, and pathology. The association of haematuria severity with incident tumour stage and grade was evaluated using logistic regression. Results Patients diagnosed with bladder cancer presented with gross haematuria (GH; 1 083, 78.3%), microscopic haematuria (MH; 189, 13.7%) or without haematuria (112, 8.1%). High‐grade disease was found in 64% and 57.1% of patients presenting with GH and MH, respectively, and severity of haematuria was not associated with higher grade disease. Stage of disease at diagnosis for patients presenting with MH was Ta/carcinoma in situ (CIS) in 68.8%, T1 in 19.6%, and ≥T2 in 11.6%. Stage of disease at diagnosis for patients presenting with GH was Ta/CIS in 55.9%, T1 in 19.6%, and ≥T2 in 17.9%. On multivariate analyses, GH was independently associated with ≥T2 disease at diagnosis (odds ratio 1.69, 95% confidence interval 1.05–2.71, P = 0.03). Conclusions Among patients with newly diagnosed bladder cancer, presentation with GH is associated with a more advanced pathological stage. Earlier detection of disease, before development of GH, could influence survival in patients with bladder cancer. Type of haematuria at presentation does not impact grade of disease.
       
  • Level of evidence, sponsorship, conflict of interest policy and commercial
           impact of PubMed‐listed clinical urolithiasis‐related trials
           in 2014
    • Abstract: Objectives To evaluate published trials on urolithiasis regarding level of evidence, type of sponsorship and declared conflicts of interest (COIs), and to elucidate a potential commercial impact. Materials and Methods We performed a systematic PubMed® literature search using a predefined Boolean search term to identify PubMed‐listed clinical research studies on urolithiasis in 2014 (fourth quarter). All authors screened the results for eligibility criteria and two independent reviewers evaluated and performed data extraction of predefined endpoints, including level of evidence, declaration of COI and sponsorship/funding (as indicated in the published print version), and commercial impact. Results A total of 110 clinical trials in urolithiasis listed in PubMed met the inclusion criteria. Levels of evidence 1, 2, 3 and 4 were found in 15%, 14%, 21% and 51% of trials, respectively. A COI was indicated in a total of 90% of publications, 93% of which declared no existing conflict of interest. Sponsorship was indicated in 36% of publications, 55% of which stated public funding, 33% institutional funding, 10% industrial funding and 2% both public and industrial funding. A total of 11% of the published trials were rated as having a high commercial impact. Conclusion The present study provides evidence of increasing levels of evidence for published clinical trials on urolithiasis in 2014 (as compared with earlier data). Ninety percent of publications indicated conflicts of interest, whereas sponsoring of studies was declared only by one‐third. A considerable number of trials involved issues of high commercial impact. Recently established legal programmes and voluntary acts on self‐reporting of financial relationships will enhance transparency in the future; however, increased public funding will be needed to further promote the quality of trials on urolithiasis.
       
  • Prognosis of patients with metastatic renal cell carcinoma and pancreatic
           metastases
    • Abstract: Objectives To identify the clinical outcomes of patients with metastatic renal cell carcinoma (mRCC) with pancreatic metastases (PM) treated with either pazopanib or sunitinib and assess whether PM is an independent prognostic variable in the current therapeutic environment. Patients and Methods A retrospective review of patients with mRCC in an outpatient clinic was carried out for the period January 2006 to November 2011. Patient characteristics, including demographics, laboratory data and outcomes, were analysed. Baseline characteristics were compared using chi‐squared and t‐tests and overall survival (OS) and cancer‐specific survival (CSS) rates were estimated using Kaplan–Meier methods. Predictors of OS were analysed using Cox regression. Results A total of 228 patients were reviewed, of whom 44 (19.3%) had PM and 184 (81.7%) had metastases to sites other than the pancreas. The distribution of baseline characteristics was equal in both groups, with the exception of a higher incidence of previous nephrectomy, diabetes and number of metastatic sites in the PM group. Four patients had isolated PM, but the majority of patients (68%) with PM had at least three different organ sites of metastases, as compared with 29% in patients without PM (P < 0.01). The distribution of organ sites of metastases was similar, excluding the pancreas, in those with and those without PM (P > 0.05). The median OS was 39 months (95% confidence interval [CI] 24–57, hazard ratio 0.66, 95% CI 0.42–0.94; P = 0.02) for patients with PM, compared with 26 months (95% CI 21–31) for patients without PM (P < 0.01). CSS was 42 months (95% CI 30–57) in the PM group and 27 months (95% CI 22–33) in the control group (P = 0.05). Conclusions Despite a higher number of affected organ sites in the PM cohort, mRCC behaviour in this cohort appears to be more indolent, as demonstrated by a higher median OS. These findings suggest that host or tumour features associated with PM may represent a less aggressive tumour phenotype.
       
  • Novel fluorescence in situ hybridization‐based definition of
           bacille Calmette‐Guérin (BCG) failure for use in enhancing
           recruitment into clinical trials of intravesical therapies
    • Abstract: Objectives To present a molecular definition of bacille Calmette‐Guérin (BCG) failure that incorporates fluorescence in situ hybridization (FISH) testing to predict BCG failure before it becomes clinically evident, which can be used to enhance trial designs for patients with non‐muscle‐invasive bladder cancer. Patients and Methods We used data from 143 patients who were followed prospectively for 2 years during intravesical BCG therapy, during which time FISH assays were collected and correlated to clinical outcomes. Results Of the 95 patients with no evidence of tumour at 3‐month cystoscopy, 23 developed tumour recurrence and 17 developed disease progression by 2 years. Patients with a positive FISH test at both 6 weeks and 3 months were more likely to develop tumour recurrence (17/37 patients [46%] and 16/28 patients [57%], respectively) than patients with a negative FISH test (6/58 patients [10%] and 3/39 patients [8%], respectively; both P < 0.001). Using hazard ratios for recurrence with positive 6‐week and 3‐month FISH results, we constructed clinical trial scenarios whereby patients with a negative 3‐month cystoscopy and positive FISH result could be considered to have ‘molecular BCG failure’ and could be enrolled in prospective, randomized clinical trials comparing BCG therapy (control) with an experimental intravesical therapy. Conclusions Patients with positive early FISH and negative 3‐month cystoscopy results can be considered to have molecular BCG failure based on their high rates of recurrence and progression. This definition is intended for use in designing clinical trials, thus potentially allowing continued use of BCG as an ethical comparator arm.
       
  • Bone Scan Index predicts outcome in patients with metastatic
           hormone‐sensitive prostate cancer
    • Abstract: Objective To evaluate the Bone Scan Index (BSI) for prediction of castration resistance and prostate cancer‐specific survival (PCSS). In this retrospective study, we used novel computer‐assisted software for automated detection/quantification of bone metastases by BSI. Patients with prostate cancer are M‐staged by whole‐body bone scintigraphy (WBS) and categorised as M0 or M1. Within the M1 group, there is a wide range of clinical outcomes. The BSI was introduced a decade ago providing quantification of bone metastases by estimating the percentage of bone involvement. Being too time consuming, it never gained widespread clinical use. Patients and Methods In all, 88 patients with prostate cancer awaiting initiation of androgen‐deprivation therapy due to metastases were included. WBS was performed using a two‐headed γ‐camera. BSI was obtained using the automated platform EXINI bone (EXINI Diagnostics AB, Lund, Sweden). In Cox proportional hazard models, time to castration‐resistant prostate cancer (CRPC) and PCSS were modelled as the dependent variables, whereas prostate‐specific antigen (PSA) level, Gleason score and BSI were used as explanatory factors. For Kaplan–Meier estimates, BSI groups were dichotomously split into: BSI
       
  • Open‐label study evaluating outpatient urethral sphincter injections
           of onabotulinumtoxinA to treat women with urinary retention due to a
           primary disorder of sphincter relaxation (Fowler's syndrome)
    • Abstract: Objectives To assess the efficacy (defined as improvements in maximum urinary flow rate [Qmax] of ≥50%, post‐void residual urine volume [PVR] and scores on the International Prostate Symptom Score [IPSS] questionnaire) and safety of urethral sphincter injections of onabotulinumtoxinA in women with a primary disorder of urethral sphincter relaxation, characterised by an elevated urethral pressure profile (UPP) and specific findings at urethral sphincter electromyography (EMG), i.e. Fowler's syndrome. Patients and Methods In this open‐label pilot Institutional Review Board‐approved study, 10 women with a primary disorder of urethral sphincter relaxation (elevated UPP, sphincter volume, and abnormal EMG) presenting with obstructed voiding (five) or in complete urinary retention (five) were recruited from a single tertiary referral centre. Baseline symptoms were assessed using the IPSS, and Qmax and PVR were measured. After 2% lidocaine injection, 100 U of onabotulinumtoxinA was injected into the striated urethral sphincter, divided on either side, under EMG guidance. Patients were reviewed at 1, 4 and 10 weeks after injection, and assessed using the IPSS, Qmax and PVR measurements. The UPP was repeated at week 4. Results The mean (range) patient age was 40 (25–65) years, and the mean symptom scores on the IPSS improved from 25.6 to 14.1, and the mean ‘bother’ score reduced from 6.1 to 3.5 at week 10. As compared with a baseline mean Qmax of 8.12 mL/s in the women who could void, the Qmax improved to 15.8 mL/s at week 10. Four of the five women in complete retention could void spontaneously, with a mean Qmax of 14.3 mL/s at week 10. The mean PVR decreased from 260 to 89 mL and the mean static UPP improved from 113 cmH2O at baseline to 90 cmH2O. No serious side‐effects were reported. Three women with a history of recurrent urinary tract infections developed a urinary tract infection. There were no reports of stress urinary incontinence. Seven of the 10 women opted to return for repeat injections. Conclusions This pilot study shows an improvement in patient‐reported lower urinary tract symptoms, and the objective parameters of Qmax, PVR and UPP, at 10 weeks after urethral sphincter injections of onabotulinumtoxinA. No serious side‐effects were reported. This treatment could represent a safe outpatient treatment for young women in retention due to a primary disorder of urethral sphincter relaxation. However, a larger study is required to confirm the findings of this pilot study.
       
  • Long‐term response to renal ischaemia in the human kidney after
           partial nephrectomy: results from a prospective clinical trial
    • Abstract: Objective To assess the 1‐year renal functional changes in patients undergoing partial nephrectomy with intra‐operative renal biopsies. Patients and Methods A total of 40 patients with a single renal mass deemed fit for a partial nephrectomy were recruited prospectively between January 2009 and October 2010. We performed renal biopsies of normal renal parenchyma and collected serum markers before, during and after surgically induced renal clamp ischaemia during the partial nephrectomy. We then followed patients clinically with interval serum creatinine and physical examination. Results Peri‐operative data from 40 patients showed a transient increase in creatinine levels which did not correlate with ischaemia time. Renal ultrastructural changes were generally mild and included mitochondrial swelling, which resolved at the post‐perfusion biopsy. A total of 37 patients had 1‐year follow‐up data. Creatinine at 1 year increased by 0.121 mg/dL, which represents a 12.99% decrease in renal function from baseline (preoperative creatinine 0.823 mg/dL, estimated glomerular filtration rate = 93.9 mL/min/1.73 m2). The only factors predicting creatinine change on multivariate analysis were patient age, race and ischaemia type, with cold ischaemia being associated with higher creatinine level. Importantly, the duration of ischaemia did not show any significant correlation with renal function change, either as a continuous variable (P = 0.452) or as a categorical variable (P = 0.792). Conclusions Our data suggest that limited ischaemia is generally well tolerated in the setting of partial nephrectomy and does not directly correspond to long‐term renal functional decline. For surgeons performing partial nephrectomy, the kidney can be safely clamped to ensure optimum oncological outcomes.
       
  • Metastases to the kidney: a comprehensive analysis of 151 patients from a
           tertiary referral centre
    • Abstract: Objective To describe the presentation, treatment and outcomes of patients with metastatic tumours to the kidney treated at a tertiary referral centre. Patients and Methods We retrospectively identified 151 patients diagnosed with a primary non‐renal malignancy with renal metastasis. Clinical, radiographic and pathological characteristics were assessed. Overall survival (OS) was calculated using Kaplan–Meier methods. Results The median patient age was 56.7 years. The most common presenting symptoms were flank pain (30%), haematuria (16%) and weight loss (12%). Most primary cancers were carcinomas (80.8%). The most common primary tumour sites were lung (43.7%), colorectal (10.6%), head and neck (6%), breast (5.3%), soft tissue (5.3%) and thyroid (5.3%). Renal metastases were typically solitary (77.5%). Concordance between radiologist and clinician imaging assessment was 54.0%. Three ablations and 48 nephrectomies were performed. For non‐surgical patients, renal metastasis diagnosis was made with fine‐needle aspiration or biopsy. The median OS from primary tumour diagnosis was 3.08 years and the median OS from time of metastatic diagnosis was 1.13 years. For patients treated with surgery, median OS from primary tumour diagnosis was 4.81 years, and OS from metastatic diagnosis was 2.24 years. Conclusions Metastases to the kidney are a rare entity. Survival appears to be longer in patients who are candidates for and are treated with surgery. Surgical intervention in carefully selected patients with oligometastatic disease and good performance status should be considered. A multidisciplinary approach with input from urologists, oncologists, radiologists and pathologists is needed to achieve the optimum outcomes for this specific patient population.
       
  • Impact of frailty on complications in patients undergoing common
           urological procedures: a study from the American College of Surgeons
           National Surgical Quality Improvement database
    • Abstract: Objectives To evaluate the association of frailty, a measure of diminished physiological reserve, with both major and minor surgical complications among patients undergoing urological surgery. Materials and Methods Using data from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) from 2007 to 2013, we identified all urological cases that appeared > 1000 times in the dataset among patients aged ≥40 years. Frailty was measured using the NSQIP frailty index (FI), a validated measure that includes 11 impairments, such as decreased functional status and impaired sensorium. We created multivariable logistic regression models using the NSQIP FI to assess major and minor complications after surgery. Results We identified 95 108 urological cases representing 21 urological procedures. The average frequency of complications per individual was 11.7%, with the most common complications being hospital readmission (6.2%), blood transfusion (4.6%) and urinary tract infection (3.1%). Major and minor complications increased with increasing NSQIP FI. Frailty remained strongly associated with complications after adjustment for year, age, race, smoking status and method of anaesthesia (adjusted odds ratio 1.74 [95% confidence interval 1.64, 1.85] for an NSQIP FI ≥0.18). Increasing NSQIP FI was associated with increasing frequency of complications within age groups (by decade) up to age 81 years and across most procedures. Conclusion Frailty strongly correlates with risk of postoperative complications among patients undergoing urological surgery. This finding is true within most age groups and across most urological procedures.
       
  • Indoor cold exposure and nocturia: a cross‐sectional analysis of the
           HEIJO‐KYO study
    • Abstract: Objectives To investigate the association between indoor cold exposure and the prevalence of nocturia in an elderly population. Subjects and Methods The temperature in the living rooms and bedrooms of 1 065 home‐dwelling elderly volunteers (aged ≥60 years) was measured for 48 h. Nocturia (≥2 voids per night) and nocturnal urine production were determined using a urination diary and nocturnal urine collection, respectively. Results The mean ± sd age of participants was 71.9 ± 7.1 years, and the prevalence of nocturia was 30.8%. A 1 °C decrease in daytime indoor temperature was associated with a higher odds ratio (OR) for nocturia (1.075, 95% confidence interval [CI] 1.026–1.126; P = 0.002), independently of outdoor temperature and other potential confounders such as basic characteristics (age, gender, body mass index, alcohol intake, smoking), comorbidities (diabetes, renal dysfunction), medications (calcium channel blocker, diuretics, sleeping pills), socio‐economic status (education, household income), night‐time dipping of ambulatory blood pressure, daytime physical activity, objectively measured sleep efficiency, and urinary 6‐sulphatoxymelatonin excretion. The association remained significant after adjustment for nocturnal urine production rate (OR 1.095 [95% CI 1.042–1.150]; P < 0.001). Conclusions Indoor cold exposure during the daytime was independently associated with nocturia among elderly participants. The explanation for this association may be cold‐induced detrusor overactivity. The prevalence of nocturia could be reduced by modification of the indoor thermal environment.
       
  • URB937, a peripherally restricted inhibitor for fatty acid amide
           hydrolase, reduces prostaglandin E2‐induced bladder overactivity and
           hyperactivity of bladder mechano‐afferent nerve fibres in rats
    • Abstract: Objective To determine if inhibition of the endocannabinoid‐degrading enzyme fatty acid amide hydrolase (FAAH) can counteract the changes in urodynamic variables and bladder afferent activities induced by intravesical prostaglandin E2 (PGE2) instillation in rats. Materials and methods In female Sprague–Dawley rats we studied the effects of URB937, a peripherally restricted FAAH inhibitor, on single‐unit afferent activity (SAA) during PGE2‐induced bladder overactivity (BO). SAA measurements were made in urethane‐anaesthetised rats and Aδ‐ and C‐fibres were identified by electrical stimulation of the pelvic nerve and by bladder distention. Cystometry (CMG) in conscious animals and during SAA measurements was performed during intravesical instillation of PGE2 (50 or 100 μm) after intravenous administration of URB937 (0.1 and 1 mg/kg) or vehicle. In separate experiments, the comparative expressions of FAAH and cannabinoid receptors, CB1 and CB2, in microsurgically removed L6 dorsal root ganglion (DRG) were studied by immunofluorescence. Results During CMG, 1 mg/kg URB937, but not vehicle or 0.1 mg/kg URB937, counteracted the PGE2‐induced changes in urodynamic variables. PGE2 increased the SAAs of C‐fibres, but not Aδ‐fibres. URB937 (1 mg/kg) depressed Aδ‐fibre SAA and abolished the facilitated C‐fibre SAA induced by PGE2. The DRG nerve cells showed strong staining for FAAH, CB1 and CB2, with a mean (sem) of 77 (2)% and 87 (3)% of FAAH‐positive nerve cell bodies co‐expressing CB1 or CB2 immunofluorescence, respectively. Conclusion The present results show that URB937, a peripherally restricted FAAH inhibitor, reduces BO and C‐fibre hyperactivity in the rat bladder provoked by PGE2, suggesting an important role of the peripheral endocannabinoid system in BO and hypersensitivity.
       
  • A prospective multicentric international study on the surgical outcomes
           and patients’ satisfaction rates of the ‘sliding’
           technique for end‐stage Peyronie's disease with severe shortening of
           the penis and erectile dysfunction
    • Abstract: Objectives To report the results from a prospective multicentric study of patients with Peyronie's disease (PD) treated with the ‘sliding’ technique (ST). Patients and Methods From June 2010 to January 2014, 28 consecutive patients affected by stable PD with severe penile shortening and end‐stage erectile dysfunction (ED) were enrolled in three European PD tertiary referral centres. The validated International Index of Erectile Function (IIEF) questionnaire, the Sexual Encounter Profile (SEP) Questions 2 and 3, and the Peyronie's disease questionnaire (PDQ) were completed preoperatively by all patients. At the follow‐up visits (at 3, 6 and 12 months), the IIEF, the SEP Questions 2 and 3, the PDQ, and the Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) were completed. The outcome analysis was focused on penile length restoration, and intra‐ and postoperative complications classified according the Clavien–Dindo Classification. Results The mean (range) follow‐up was 37 (9–60) months. A malleable penile prosthesis (PP) was implanted in seven patients, while an inflatable three‐pieces PP was placed in the remainder. In the case of inflatable PP implantation, porcine small intestinal submucosa and acellular porcine dermal matrix were used to cover the tunical defects. While in patients undergoing malleable PP implantation, collagen‐fibrin sponge was used. The mean operative time was 145 min in the inflatable PP group and 115 min in the malleable PP group. There were no intraoperative complications. Postoperative complications included profuse bleeding requiring a blood transfusion in one patient (3.5%) on anticoagulation therapy for a mechanical heart valve (Grade II) and PP infection requiring the removal of the device (7%) (Grade III). There were no late recurrences of the shaft deformation. The postoperative functional data showed a progressive improvement in the score of all questionnaires, peaking at 12 months postoperatively. The mean (range) penile lengthening was 3.2 (2.5–4) cm and no patient reported recurrence of the curvature. Conclusions The present series suggests that, in the hands of experienced high‐volume surgeons, penile length restoration with the use of the ST represents an effective option for end‐stage PD associated with ED and severe shortening of the shaft. Larger series and longer follow‐up will be required to fully establish the efficacy of this procedure.

           cancer: results from patients treated with radical prostatectomy over the
           last two decades
    • Abstract: Objective To evaluate the impact of year of surgery on clinical, pathological and oncological outcomes of patients with high‐risk prostate cancer. Patients and Methods We evaluated 1 033 patients with clinically high‐risk prostate cancer, defined as the presence of at least one of the following risk factors: preoperative prostate‐specific antigen (PSA) level >20 ng/mL, and/or clinical stage ≥T3, and/or biopsy Gleason score ≥8. Patients were treated between 1990 and 2013 at a single institution. The year‐by‐year trends in clinical and pathological characteristics were examined. Multivariable Cox regression analysis was used to test the relationship between year of surgery and oncological outcomes. Results We observed a decrease over time in the proportion of patients with high‐risk disease (preoperative PSA >20 ng/mL or clinical stage cT3). A trend in the opposite direction was seen for biopsy Gleason score ≥8 tumours. We observed a considerable increase in the median number of lymph nodes removed, which was associated with an increased rate of lymph node invasion (LNI). On multivariable Cox regression analysis, year of surgery was associated with a reduced risk of biochemical recurrence (hazard ratio [HR] per 5‐year interval 0.90, 95% confidence interval [CI] 0.84–0.96; P = 0.01) and distant metastasis (HR per 5‐year interval 0.91, 95% CI 0.83–0.99; P = 0.039), after adjusting for age, preoperative PSA, pathological stage, LNI, surgical margin status, and pathological Gleason score. Conclusions In this single‐centre study, an increased diagnosis of localized and less extensive high‐grade prostate cancer was observed over the last two decades. Patients with high‐risk disease who were selected for radical prostatectomy showed better cancer control over time. Better definitions of what constitutes high‐risk prostate cancer among contemporary patients are needed.
       
  • Patient‐physician‐communication and health related quality of
           life of localized prostate cancer patients undergoing radical
           prostatectomy – a longitudinal multilevel analysis
    • Abstract: Objectives To examine whether patient‐physician‐communication is associated with health related quality of life (HRQoL) in a sample of localized prostate cancer patients after radical prostatectomy. Patients and methods HAROW is a prospective, observational study designed to collect data of the different treatment options (Hormonal therapy, Active Surveillance, Radiation, Operation, Watchful Waiting) for newly diagnosed patients with localized prostate cancer under real life conditions. At 6‐months intervals, clinical data (D'Amico risk categories, Charlson comorbidity index) aspects of patient‐provider‐communication (standardized psychosocial care‐instrument for patients’ assessment of communication; Cologne Patient Questionnaire), and HRQoL (EORTC QLQ‐C30) were assessed. Data were analyzed by longitudinal multilevel analysis. Results Completed questionnaires for N=1.772 patients undergoing a prostatectomy were analyzed for a 3 year follow‐up period. Patients rate the patient‐provider communication generally high with slight variations over the course of treatment (3.2‐3.8). The HRQoL of the patients shows substantial variation over time and between the reported subscales (Global Qol 71,1‐77,2; physical functioning 89,1‐92,1; role functioning 81,0‐88,1; emotional functioning 74,4‐84,0; cognitive functioning 84,3‐87,7; social functioning 77,7‐84,0). The longitudinal multilevel models showed significant associations between the patient‐provider communication in terms of devotion, support and co‐therapy and functional aspects of HRQoL. Conclusion Patient‐provider communication is a valuable resource to support prostate cancer patients’ coping with the disease and to improve their HRQoL. Future interventions should be designed especially for urologists to enhance their awareness for the importance of communication and the relationship to their prostate cancer patients for treatment outcomes.
