INTRODUCTION: Clinically significant prostate cancer (csCaP) with Gleason ≥3 + 4 is found in 10% negative prebiopsy multiparametric (mp) MRI cases and varies widely for equivocal mpMRI cases. The objective of this study was to investigate long-term outcomes of patients with negative and equivocal mpMRIs and to develop a predictive score for csCaP risk stratification in this group. PATIENTS AND METHODS: Patients who underwent an upfront mpMRI between May 2015 and March 2018 with an MRI score Likert 1 to 3 were included in the study. Patients had either a CaP diagnosis at MRI-targeted biopsy or were not diagnosed and attended follow-up in the community. Outcomes were analysed through the Kaplan-Meier estimator and Cox Model. Regression coefficients of significant variables were used to develop a Risk of significant Cancer of the Prostate score (RosCaP). RESULTS: At first assessment 281/469 patients had mpMRI only and 188/469 mpMRI and biopsy, 26 csCaP were found at biopsy, including 10/26 in Likert 3 patients. 12/371 patients discharged without CaP after first assessment were diagnosed with csCaP during a median of 34.2 months' follow-up, 11/12 diagnosis occurred in patients omitting initial biopsy. csCaP diagnosis-free survival was 95.7% in the MRI group and 99.1% in the biopsy group. From these outcomes, a continuous RosCaP score was developed: RosCaP = 0.083 x Age - 0.202 x (1/PSA Density) + 0.786 (if Likert 3), and 4 risk classes were proposed. Limitations include retrospective design and absence of external validation. CONCLUSION: Age, PSA Density and MRI Likert score were significantly associated to the risk of csCaP and utilised to devise the novel RosCap predictive score focused to support risk assessment in patients with negative or equivocal mpMRI results.

Prostate MRI is an essential tool in the diagnostic pathway of prostate cancer and its accurate reading helps decision to biopsy. The aim of this study was to assess the Urology residents' level of confidence in reading and interpreting prostate MRI, their interest in new learning opportunities and whether prostate MRI training should be part of the urology core curriculum during residency.A 23-item survey has been created and distributed via Web to an international cohort of Urology residents over a 3-month period. Surveys obtained from Countries representing10% total distribution of responses were analysed.A total of 304 complete surveys were obtained from Urology residents, with a geographical prevalence from Europe (59.54%, 181/304) and South America (29.28%, 89/304). Only 17-20% of residents reported having received formal prostate MRI training during residency. Overall,20% residents expressed to feel confident in reading and interpreting prostate MRI. As a result,90% Urology trainees stated they would be willing to receive a formal training and would be interested in new learning opportunities in MRI reading and interpretation during residency, independently of their year of training. Despite UK Urology trainees showed to have a higher availability of MRI resources and MRI-based biopsies compared to the other countries, they still expressed concerns in regard to not feeling confident with MRI reading and interpretation and requested a formal training.This survey highlights the need for major learning opportunities and a formal training in prostate MRI reading and interpretation during urology residency.

To present a new technique of double-j stent (DJ) placement during laparoscopic transperitoneal ureterolithotomy (LUL).Following the extraction of the stone, a 6 French DJ open-end stent is prepared: two straight-tip hydrophilic guidewires are inserted into the appropriate lateral holes of the stent, as identified by the preoperative evaluation of the CT scan. Approximately 5 centimeters of each wire protrude from the proximal and distal ends of the stent to straighten its terminal curl, thus resembling the wings of a flying seagull. The remaining proximal portions of both guide wires are left within each guidewire dispenser. The two ends of the stent are grasped together in a U-fashion and inserted into the abdomen through a 10mm port. Once in the abdomen, the longer segment of the stent is inserted and pushed into the ureterotomy until it reaches the target site. The guide wire is then removed. The same procedure is repeated for the other end of the stent. A brief literature review on the currents techniques of laparoscopic DJ placement is also presented.Analyzing the outcomes of 21 LUL, the "seagull" technique is time-saving and safe. No perioperative complications were encountered. There is no risk of enlarging or tearing the ureterotomy and no need for patient replacement, extra cystoscopic or ureteroscopic procedures as well as of using modified guidewires and closed-tip stents.We described our step-by-step technique for DJ placement during LUL.

Purpose Training in retrograde intrarenal surgery for the treatment of renal stone disease is a challenging task due to the unique complexity of the procedure. This study introduces a series of 3D printed models of upper urinary tract and stones designed to improve the training process. Methods Six different models of upper urinary tract were algorithmically isolated, digitally optimized and 3D printed from real-life cases. Soft and hard stones in different sizes were produced from 3D printed moulds. The models were fitted onto a commercially available part-task trainer and tested for retrograde intrarenal surgery. Results Each step of the procedure was simulated with extraordinary resemblance to real-life cases. The unique anatomical intricacy of each model and type of stones allowed us to reproduce surgeries of increasing difficulty. As the case-load required to achieve proficiency in retrograde intrarenal surgery is high, benchtop simulation could be integrated in training programs to reach good outcomes and low complication rates faster. Our models match incredible anatomical resemblance with low production cost and high reusability. Validation studies and objective skills assessment during simulations would allow comparison with other available benchtop trainers and the design of stepwise training programs. Conclusions 3D printing is gaining a significant importance in surgical training. Our 3D printed models of the upper urinary tract might represent a risk-free training option to hasten the achievement of proficiency in endourology.

Basic simulation training in endourology was established with the endoscopic stone treatment step 1 (EST-s1), which is now recognized worldwide for training and examination. Following on from EST-s1, the endoscopic stone treatment step 2 (EST-s2) was started by the European Association of Urology (EAU) sections. Objective: We describe the methodology used in the development of EST-s2 assessment curriculum. Materials and Methods: The "full-life cycle curriculum development"template was followed for curriculum development, focusing on intermediate training of EST protocol with complex endourologic tasks. A cognitive task analysis (CTA) was run in accordance with EAU Urolithiasis guidelines. The protocol and its details underwent a first consensus by Delphi method with EAU Urolithiasis Section experts in March 2017. Once the outcome and metrics were decided, curriculum development was carried out. Purpose-built stones were developed, and simulator system requirement was defined. Preliminary testing was done in European Urology Residents Education Programme 2019 and in phase five the protocol was finalized with full tutor instruction sheet. Results: The EST-s2/A curriculum development took 38 months and involved EAU Uro-technology and urolithiasis sections with coordination from the European School of Urology training group. Starting from the initial CTA, a 1277-word revision with preliminary task description was produced. Nine intermediate skills were identified and included in the final training protocol. The training content and session evaluations were carried out by 26 experts and 16 final year trainees, respectively. Although the experts agreed that EST-s2/A protocol was well structured (96%), covered the complex endourologic maneuvers (92%), and was useful to optimize and improve hands-on-training (HoT) sessions (92%), the overall evaluation was scored 4.25/5 by trainees. Conclusion: We describe the development methodology for intermediate EST curriculum, which also provides a roadmap on developing other HoT protocols in future. Patients Summary: In this report we described the development of the novel intermediate training curriculum for EST, called EST-s2, which took 3 years of collaborative work inside the EAU. This article is aimed to strengthen the standards in curriculum development and clearly describe the background of this new EAU official endourology protocol.

Background: The Performance Improvement score (Pi-score) has been proven to be reliable to measure performance improvement during E-BLUS hands-on training sessions. Our study is aimed to adapt and test the score to EST s1 (Endoscopic Stone Treatment step 1) protocol, in consideration of its worldwide adoption for practical training. Methods: The Pi-score algorithm considers time measurement and number of errors from two different repetitions (first and fifth) of the same training task and compares them to the relative task goals, to produce an objective score. Data were obtained from the first edition of 'ART in Flexible Course', during four courses in Barcelona and Milan. Collected data were independently analyzed by the experts for Pi assessment. Their scores were compared for inter-rater reliability. The average scores from all tutors were then compared to the PI-score provided by our algorithm for each participant, in order to verify their statistical correlation. Kappa statistics were used for comparison analysis. Results: Sixteen hands-on training expert tutors and 47 3rd-year residents in Urology were involved. Concordance found between the 16 proctors' scores was the following: Task 1=0.30 ("fair"); Task 2=0.18 ("slight"); Task 3=0.10 ("slight"); Task 4=0.20, ("slight"). Concordance between Pi-score results and proctor average scores per-participant was the following: Task 1=0.74 ("substantial"); Task 2=0.71 ("substantial"); Task 3=0.46 ("moderate"); Task 4=0.49 ("moderate"). Conclusions: Our exploratory study demonstrates that Pi-score can be effectively adapted to EST s1. Our algorithm successfully provided an objective score that equals the average performance improvement scores assigned by of a cohort of experts, in relation to a small amount of training attempts.

BACKGROUND Over the two past decades, GreenLight laser therapy has been considered a valid alternative for the treatment of lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia/benign prostatic obstruction (BPH/BPO). However, the debate on the effectiveness of laser therapy compared to conventional techniques is still open. The aim of our study is to analyze and describe the use of GreenLight laser prostate surgery in Italy, with regard to the surgical techniques performed and the surgical and functional outcomes at mid-term follow-up. METHODS From March 2012 to July 2018, patients who underwent GreenLight laser prostate surgery for LUTS due to BPH/BPO from 19 Italian centers were included. The following parameters were evaluated in the population: age, prostate volume, prostate adenoma volume, PSA tot, Q max at uroflowmetry (UFM), International Prostatic Symptoms Score (IPSS), previous therapy for LUTS, use of anticoagulants and antiplatelet drugs. We recorded also the kind of anesthesia, mean laser time (min), mean irradiation time (min), TURP conversion/completion rate, postoperative day of catheter removal, postoperative acute urinary retention (AUR), hospital stay, variation of hematocrit (Ht) and hemoglobin levels (Hb). Early complications were classified according to the Clavien-Dindo classification, the re-operation rate within 30 days and after 30 days, the late complications and the Patient Global Impression of Improvement were also collected. Changes over time in terms of blood loss and functional outcomes (IPSS and Q max at the UFM at 6 and 12 months) were tested with Student's test for paired samples. We assumed P≤0.05 as level of statistical significance. RESULTS Overall, 1077 were enrolled in the study, 554 (56.4%) were treated with standard vaporization and 523 (48.6%) with anatomical vaporization. Student's t-test for paired samples showed no statistically significant differences in terms of reduction of Ht preoperative vs. Ht postoperative (42.80±3.91 vs. 39.93±5.35 95% CI P=0.3) and preintervention and postintervention Hb levels (14.28±1.46 vs. 13.72 P=0.35). Compared with the preoperative Q max (8.60±2.64), the 6- and 12-month UFM showed a significant improvement [19.56±6.29, P

OBJECTIVE To create, distribute, and evaluate the efficacy of a portable, cost-effective 3D-printed laparoscopic trainer for surgical skills development. METHODS The UCI Trainer (UCiT) laparoscopic simulator was developed via computer-aided designs (CAD), which were used to 3D-print the UCiT. Once assembled, a tablet computer with a rear-facing camera was attached for video and optics. Four institutions were sent the UCiT CAD files with a 3D-printer and instructions for UCiT assembly. For a comparison of the UCiT to a standard trainer, peg transfer and intracorporeal knot tying skills were accessed. These tasks were scored, and participants were asked to rate their experience with the trainers. Lastly, a questionnaire was given to individuals who 3D-printed and assembled the UCiT. RESULTS We recruited 25 urologists; none had any 3D-printing experience. The cost of printing each trainer was $26.50 USD. Each institution used the Apple iPad for optics. Six of eight participants assembled the UCiT in < 45 minutes, and rated assembly as somewhat easy. On objective scoring, participants performed tasks equally well on the UCiT vs the conventional trainer. On subjective scoring, the conventional trainer provided a significantly better experience vs the UCiT; however, all reported that the UCiT was useful for surgical education. CONCLUSION The UCiT is a low cost, portable training tool that is easy to assemble and use. UCiT provided a platform whereby participants performed laparoscopic tasks equal to performing the same tasks on the more expensive, nonportable standard trainer.

Background Prostate biopsy supported by transperineal image fusion has recently been developed as a new method to the improve accuracy of prostate cancer detection. Objective To describe the Ginsburg protocol for transperineal prostate biopsy supported by multiparametric magnetic resonance imaging (mpMRI) and transrectal ultrasound (TRUS) image fusion, provide learning points for its application, and report biopsy results. The article is supplemented by a Surgery in Motion video. Design, setting, and participants This single-centre retrospective outcome study included 534 patients from March 2012 to October 2015. A total of 107 had no previous prostate biopsy, 295 had benign TRUS-guided biopsies, and 159 were on active surveillance for low-risk cancer. Surgical procedure A Likert scale reported mpMRI for suspicion of cancer from 1 (no suspicion) to 5 (cancer highly likely). Transperineal biopsies were obtained under general anaesthesia using BiopSee fusion software (Medcom, Darmstadt, Germany). All patients had systematic biopsies, two cores from each of 12 anatomic sectors. Likert 3–5 lesions were targeted with a further two cores per lesion. Outcome measurements and statistical analysis Any cancer and Gleason score 7–10 cancer on biopsy were noted. Descriptive statistics and positive predictive values (PPVs) and negative predictive values (NPVs) were calculated. Results and limitations The detection rate of Gleason score 7–10 cancer was similar across clinical groups. Likert scale 3–5 MRI lesions were reported in 378 (71%) of the patients. Cancer was detected in 249 (66%) and Gleason score 7–10 cancer was noted in 157 (42%) of these patients. PPV for detecting 7–10 cancer was 0.15 for Likert score 3, 0.43 for score 4, and 0.63 for score 5. NPV of Likert 1–2 findings was 0.87 for Gleason score 7–10 and 0.97 for Gleason score ≥4+3=7 cancer. Limitations include lack of data on complications. Conclusions Transperineal prostate biopsy supported by MRI/TRUS image fusion using the Ginsburg protocol yielded high detection rates of Gleason score 7–10 cancer. Because the NPV for excluding Gleason score 7–10 cancer was very high, prostate biopsies may not be needed for all men with elevated prostate-specific antigen values and nonsuspicious mpMRI. Patient summary We present our technique to sample (biopsy) the prostate by the transperineal route (the area between the scrotum and the anus) to detect prostate cancer using a fusion of magnetic resonance and ultrasound images to guide the sampling.

This study evaluated the role of body mass index (BMI) and dietary potential renal acid load (PRAL) with urinary saturation for calcium oxalate (US-CaOx), calcium phosphate (US-CaP) and uric acid (US-UA) in renal stone formers.A retrospective analysis was conducted of laboratory data collected on 442 renal stone-forming patients. Demographic information, BMI and 24 h urinary samples were collected from patients on their regular diets. PRAL was calculated as the Load of Acid to Kidney Evaluation (LAKE) score through a short questionnaire.Urinary risk factors, but also inhibitors of calcium stone formation such as magnesium, tended to increase in relation to BMI (p = .000). Urinary pH (p = .002) and ammonium/sulfate ratio (p = .000) were negatively related to BMI. This resulted in a positive correlation between BMI and US-UA (p = .000), whereas US-CaOx and US-CaP were not influenced by BMI. LAKE score was positively correlated with US-CaOx (p = .022) and US-CaP (p = .000) as a consequence of the inverse relationship between LAKE score and citrate (p = .000). Multiple linear regression analysis identified BMI (p = .009) and male gender (p = .002) as independent predictors of US-UA, and LAKE score (p = .004) and age (p = .001) as independent predictors of US-CaP.BMI, which depends on excessive intake of energy from food, is not related to an increased biochemical risk of calcium stone formation, which is more dependent on the renal acid load of the diet. In contrast, obesity is associated with an increased risk of uric acid stone formation due to insulin resistance, impaired ammoniagenesis and low urinary pH.

Background Nephrolithiasis is a common condition with several studies documenting an increased prevalence over the past four decades. EAU and AUA guidelines recommend 24-hour urine metabolic evaluation in high-risk stone formers. Aim of this study is to retrospectively evaluate the first three years of experience with LithoTest® (Biohealth Italia Srl, Turin, Italy) through the analysis of demographic, clinical and biochemical data collected from a large cohort of patients with kidney stones. Methods We retrospectively analyzed data from the LithoCenter database, including data from outpatient consultations, between January 2007 and December 2009 from all over Italy. LithoTest® was performed through a 24-hour urine collection and included measurements of urine volume and pH, 24-hour excretion of creatinine as well as main cations and anions, including calcium, magnesium sodium potassium, ammonium, uric acid, oxalate, citrate, phosphate, inorganic sulphate and chloride. Urine state of saturation for calcium oxalate (βCaOx), calcium hydrogen phosphate or brushite (βbsh) and uric acid (βUA) were also calculated by means of the computer program LithoRisk. Brand's test for cystinuria was also carried out. Statistical analysis was performed using the S-PSS software v. 22.0. Results The number of patients with data available for analysis was 435, of whom 236 were male (54%) and 199 female (46%). Complete 24-hour urine measurements were available for all 435 patients. Compared to men, women had significantly lower values for creatinine, urate, oxalate, phosphate, sodium, potassium, magnesium and chloride excretion, whereas 24-hour pH and citrate excretion were higher. No significant differences were found for the other examined variables. βCaOx and βUA were significantly higher in men than women, whereas no significant difference was found for βbsh. There was a direct relationship between calcium and sodium urine excretion. Excessive sodium excretion was recorded in 191 patients (44%) and low urine volumes in 201 (46.2%). Hyperoxaluria was observed in 118 patients (27.3%), hypercalciuria in 115 (26.6%), hyperuricosuria in 153 (35.4%), hypomagnesuria in 96 (22.2%), and hypocitraturia in 134 patients (31%). Hyperexcretion of sodium, hypocitraturia and hyperoxaluria were most frequent in males. βCaOx was significantly higher in the setting of hypercalciuria, hypocitraturia, hyperoxaluria and urine pH below 5.5. Conclusions Our findings in a large cohort of high-risk stone-forming patients show significant differences in urinary metabolic profiles between men and women. Carrying on the collection and analysis of data by LithoTest® from 2009 to 2015 and matching urinary and dietary data could eventually improve our understanding on the metabolic profile of stone-formers in Italy.

Introduction The aim of this study was to evaluate the current literature on single-session bilateral endoscopic surgery for renal stones, analyzing their effectiveness and safety. Evidence acquisition A systematic literature review was performed to identify articles published between 1995 and July 2016 that reported data on bilateral single-session endoscopic surgery for renal stones. Articles were separated into the following categories: bilateral PCNL, bilateral FURS and bilateral PCNL with contralateral FURS. We used a narrative synthesis for the analyses of the studies. Evidence syntesis Five reports of bilateral FURS were identified in the literature search. These studies included a total of 218 patients that underwent bilateral FURS for renal stones. The primary SFR ranged from 64% to 92.8%. Postoperative complications were mostly described as minor complications; one major complication (0.5%) (grade V) was reported. Thirteen reports of bilateral PCNL were identified. These case studies included a total of 729 patients undergoing bilateral PCNL for renal stones. The primary SFR ranged from 24% to 100%. In all the studies a total of 29 (4%) major complications were described: 28 of them grade III while one was grade IV. One single study of bilateral PCNL with contralateral FURS for renal stones was identified. This report included 26 patients and the primary SFR was 92.3%. Two major complications (7.7%) (Grade III) were described. Conclusions Bilateral single-session endoscopic procedures for bilateral renal stones are effective and safe. It should be considered a viable treatment option in carefully selected patients, performed by experienced urologists in high-volume centers. Key to success is the proper selection of patients and extending surgery on the second side only when the first side has been uneventful.

To evaluate the efficacy of prostate cancer (PCa) detection by the electronic nose (EN) on human urine samples. Urine samples were obtained from candidates of prostate biopsy (PB). Exclusion criteria were a history of urothelial carcinoma or other malignant disease, urine infection, fasting for

This study aimed to compare the pentafecta rates between laparoscopic radical prostatectomy (LRP) and robot-assisted radical prostatectomy (RALP) and to identify prognostic factors predicting the pentafecta for each technique.This prospective comparative study enrolled 248 consecutive male patients 70 years of age or younger with clinically localized prostate cancer [PCa: age ≤ 70 years, prostate-specific antigen (PSA) ≤ 10 ng/ml, biopsy Gleason score ≤ 7] who were fully continent, potent, and candidates for bilateral nerve-sparing (BNS) LRP or RALP. The pentafecta rates between LRP and RALP were compared. A logistic regression model was created to evaluate independent factors for achieving pentafecta.In the final analysis, 91 LRP and 136 RALP patients were evaluated. The median follow-up period was 21 months for the 91 LRP patients and 18 months for the 136 RALP patients (p = 0.07). Of the 227 patients, 87 reached pentafecta [25 LRP patients (27.5 %) vs 62 RALP patients (45.6 %), p = 0.006]. Of the 140 patients who failed pentafecta, 90 (64.3 %) missed a single parameter. In these cases, erectile deficit was the leading cause of pentafecta failure, with a significant [corrected] difference between groups (80 % LRP cases that missed potency recovery [corrected] vs 53.3 % RALP, p = 0.007). Lower age, lower pathologic stage, and RALP are significantly associated with pentafecta as independent factors. For the pT3 disease, the two techniques did not differ significantly.Patients submitted to BNS RP have low possibilities of achieving pentafecta. Use of the robotic platform by a single surgeon significantly enhances the possibility of achieving pentafecta independently of age and pathologic stage. Potency was the most difficult outcome to reach after surgery, and it was the main factor leading to pentafecta failure. LRP and RALP provide equivalent pentafecta rates for the pT3 disease and similar "tetrafecta" outcomes when potency recovery is not included among the postoperative expectations of the patient.

Purpose To reach standardized terminology in focal therapy (FT) for prostate cancer (PCa). Methods A four-stage modified Delphi consensus project was undertaken among a panel of international experts in the field of FT for PCa. Data on terminology in FT was collected from the panel by three rounds of online questionnaires. During a face-to-face meeting on June 21, 2015, attended by 38 experts, all data from the online rounds were reviewed and recommendations for definitions were formulated. Results Consensus was attained on 23 of 27 topics; TargetedFT was defined as a lesion-based treatment strategy, treating all identified significant cancer foci; FT was generically defined as an anatomy-based (zonal) treatment strategy. Treatment failure due to the ablative energy inadequately destroying treated tissue is defined as ablation failure. In targeting failure the energy is not adequately applied to the tumor spatially and selection failure occurs when a patient was wrongfully selected for FT. No definition of biochemical recurrence can be recommended based on the current data. Important definitions for outcome measures are potency (minimum IIEF-5 score of 21), incontinence (new need for pads or leakage) and deterioration in urinary function (increase in IPSS >5 points). No agreement on the best quality of life tool was established, but UCLA-EPIC and EORTC-QLQ-30 were most commonly supported by the experts. A complete overview of statements is presented in the text. Conclusion Focal therapy is an emerging field of PCa therapeutics. Standardization of definitions helps to create comparable research results and facilitate clear communication in clinical practice.

Introduction Premature ejaculation (PE) is a highly prevalent and complex syndrome that remains poorly defined and inadequately characterized. Pharmacotherapy represents the current basis of lifelong PE treatment. Aim The goal of this study was to assess the role of phosphodiesterase type 5 inhibitors (PDE5‐Is) in the treatment of patients with PE without associated erectile dysfunction (ED). Main Outcome Measure The posttreatment intravaginal ejaculatory latency time was used as the primary end point of efficacy. Methods A systematic review of the literature was performed by electronically searching the MedLine database for peer‐reviewed articles regarding the mechanism of action and the clinical trials of PDE5 in the management of PE. A meta‐analysis of these clinical studies was performed to pool the efficacy. Results Twenty‐nine articles that examined the supposed mechanisms of action and 14 articles that reported data from clinical studies were reviewed. The PDE5 may exert their influence by increasing the levels of nitric oxide both centrally (reducing sympathetic drive) and peripherally (leading to smooth‐muscle dilatation of the seminal tract). These drugs may also induce peripheral analgesia to prolong the duration of the erection, increase confidence, improve the perception of ejaculatory control and overall sexual satisfaction, and decrease the postorgasmic refractory time for achieving a second erection after ejaculation. Concerning the efficacy, the meta‐analysis shows an overall positive effect for the use of PDE5 as monotherapy or as components of a combination regimen in the treatment of PE. The major limitations of the published literature included poor study design, the absence of solid methodology, which was characterized by the lack of a unique PE definition, and the lack of appropriate endpoints for outcome evaluation of a placebo control arm and of Institutional Review Board approval. Conclusion There is inadequate, partial basic, and clinical evidence to support the use of PDE5 for the treatment of PE. Asimakopoulos AD, Miano R, Agro EF, Vespasiani G, and Spera E. Does current scientific and clinical evidence support the use of phosphodiesterase type 5 inhibitors for the treatment of premature ejaculation? A systematic review and meta‐analysis.

Objective:To test high-intensity focused ultrasound (HIFU) as salvage first-line treatment for palpable, TRUS-evidenced, biopsyproven locally recurrent prostate cancer (CaP) after radical prostatectomy (RP). Materials and methods:Nineteen patients with palpable, TRUS-evidenced, biopsy-proven local recurrence of CaP after RP, unwilling to undergo salvage radiotherapy (SRT), underwent HIFU as a single-session procedure. Pre-, intra-, and postoperative data including early and late complications, and oncologic outcomes (PSA nadir, biochemical recurrence (BCR)-free survival, and need of secondary adjuvant treatment) were prospectively evaluated. Success was defined as PSA nadir!0.1 ng/ml obtained within 3 months from HIFU. In case of PSA nadir!0.1 ng/ml or PSA increase"1 ng/ml above the PSA nadir, a biopsy of the treated lesion was performed, and if negative, maximum androgen blockade (MAB) was adopted. In case of positive biopsy, RT was performed. Failure was defined as use of secondary adjuvant treatment (MAB or RT). Results:Median follow-up was 48 months. All cases were performed as overnight procedure. No case of urethrorectal fistula or anastomotic stricture was observed. Two cases of acute urinary retention were resolved with prolonged urethral catheterization. Four cases of stress urinary incontinence were observed; 2 (mild incontinence) were resolved after pelvic floor exercises within 6 months, while 2 cases of severe incontinence required surgical minimally invasive treatment;17/19 patients (89,5%) were classified as success. Two patients failed to show a PSA nadir"0.1 ng/ml. During follow-up, 8/17 patients (47%) were classified as failure, with consequent total rate of failures 10/19 (52.6%). A statistically significant difference was observed in pre-HIFU median PSA (2 vs. 5.45 ng/ml, respectively,P#0.013) and Gleason score of the RP specimen (P#0.01) between the success and failure group. Conclusions:Salvage first-line HIFU for palpable, TRUS-evidenced, biopsy-proven local recurrence of CaP is a feasible, minimally invasive day-case procedure, with an acceptable morbidity profile. It seems to have a good cancer control in the short- and mid-term. Patients with lower pre-HIFU PSA level and favorable pathologic Gleason score presented better oncologic outcomes. A prospective randomized trial with an adequate recruitment and follow-up is necessary to confirm our preliminary oncologic results. © 2011 Elsevier Inc. All rights reserved.

BACKGROUND: To evaluate the association between metabolic syndrome (MS) and prostate cancer diagnosis and grade in patients undergoing prostate biopsy. METHODS: From 2009 onwards, a consecutive series of patients undergoing 12-core prostate biopsy for PSA value ≥4 ng/ml and/or positive digital rectal examination (DRE) were prospectively enrolled. Body mass index (BMI), waist circumferences, and blood pressure were measured before the biopsy. Blood samples were tested for: PSA, fasting glucose, triglycerides, and cholesterol HDL. MS presence was defined according to Adult Treatment Panel III criteria. RESULTS: One hundred ninety five patients were enrolled with a median age and PSA of 69 years and 5.6 ng/ml respectively. Median BMI was 27.6 kg/m(2) with 64 patients (33%) being classified as obese (BMI ≥ 30 kg/m(2) ). Eighty-six patients (44%) had MS. Eighty-three patients (43%) had cancer on biopsy; 37 (45%) with MS and 46 (55%) without (P = 0.48). PSA was independently associated with higher risk of cancer (OR 1.12/1 U PSA, P = 0.01). Out of 83 patients with prostate cancer, 42 (51%) had Gleason score 6 (12 (28.5%) presented a MS) and 41 (49%) a Gleason score ≥7 (25 (61%) presented a MS). The presence of MS was not associated with an increased risk prostate cancer (OR: 0.97, P = 0.94) but with an increased risk of Gleason ≥7 (OR: 3.82; P = 0.013). CONCLUSIONS: In our single center study, MS is associated with an increased risk of high grade Gleason score when prostate cancer is diagnosed on biopsy. However, these results should be confirmed in a larger multicenter study. Prostate © 2011 Wiley-Liss, Inc.

To evaluate the effect of tamsulosin on reducing the serum levels of prostate-specific antigen (PSA) in patients with lower urinary tract symptoms and an elevated PSA level.From June 2004 to July 2006, patients with lower urinary tract symptoms, a PSA level ofor=4 ng/mL, and a maximal flow rate of15 mL/s received tamsulosin 0.4 mg daily for 2 months. They were then scheduled for 12-core prostate biopsy. PSA determination and a uroflow study were performed before biopsy.A total of 80 patients completed the present study. The mean patient age was 66.3 years, and the mean PSA level was 7.8 +/- 8.4 ng/mL at baseline and 7.1 +/- 9.1 ng/mL after treatment (P.001). A total of 29 patients (36.25%) were diagnosed with prostate cancer from the biopsy findings. A significant increment in the PSA level was observed in patients with prostate cancer (6.7 versus 7.9 ng/mL; P = .002). A significant decrease in the PSA level was observed in patients with negative biopsy findings (6.9 versus 5.1 ng/mL, P = .000). Of the 38 patients with a decrease in the PSA level, 1 (2.6%) was diagnosed with prostate cancer and 37 (97.4%) with an benign prostatic hyperplasia/prostatitis. Of the 42 patients with no change in the PSA level, 28 (66.7%) had prostate cancer and 14 (33.3%) had negative findings. A change in PSA level after treatment gave a sensitivity of 96.6%, specificity of 72.5%, and diagnostic accuracy of 81% for prostate cancer.Treatment with tamsulosin seemed to reduce the PSA levels and identified patients at high risk of prostate cancer.

The development and introduction in clinical practice of finasteride, the first potent inhibitor of steroid 5-alpha-reductase that inhibits the conversion of testosterone to its active form dihydroxytestosterone, has created the possibility to prevent and treat prostatic disorder by manipulating and lowering the androgens levels in the prostate. Randomised and placebo-controlled trials have demonstrated the benefit of finasteride in men with enlarged prostatic gland owing to benign prostatic hyperplasia in terms of symptoms and urinary flow rate improvements. The Prostate Cancer Prevention Trial has clearly stated the chemopreventive properties of finasteride for prostate cancer but the necessity to provide such preventive therapy to a specific group of men with a higher risk to develop a clinically significant disease is under discussion. Finasteride is administered orally as a single daily dose. We recommend a 5 mg dose.

Objective: To compare acute and chronic effects of l-dopa on bladder function in levodopa-naive Parkinson disease (PD) patients who had urinary urgency. Methods: We evaluated 26 l-dopa–naive PD patients at a university-based PD center with a first urodynamic session with a double examination: in the off treatment condition and 1 hour after acute challenge with carbidopa/l-dopa 50/200 mg; then, a chronic l-dopa monotherapy was administered (mean dose 300 ± 150 mg). Two months later, patients underwent a second urodynamic session with a single evaluation 1 hour after the acute carbidopa/l-dopa challenge. Results: The first acute l-dopa challenge significantly worsened bladder overactivity (neurogenic overactive detrusor contractions threshold [NDOC-t; 32% of worsening] and bladder capacity [BC; 22% of worsening]); on the contrary, l-dopa challenge during chronic administration ameliorated the first sensation of bladder filling (FS; 120% of improvement), NDOCT-t (93% improvement), and BC (33% of improvement) vs the values obtained with acute administration. An 86% significant improvement of FS in comparison with the basal value was observed. Conclusions: The acute and chronic l-dopa effects may be due to the different synaptic concentrations or to the activation of postsynaptic mechanisms obtained by chronic administration.

The term infection stones refers to calculi that occur following urinary tract infections (UTIs) caused by urease-producing gram-negative organisms. They consist of magnesium ammonium phosphate, carbonate apatite and monoammonium urate. Alkaline urine is most favorable to their formation. Urinary tract obstruction, neurogenic bladder, voiding dysfunction, temporary or indwelling urinary catheters, distal renal tubular acidosis and medullary sponge kidney are considered the main risk factors for developing infection stones. Urinalysis and urine culture are essential for diagnosis. A typical finding on imaging is a moderately radiopaque, staghorn or branched stone. Curative treatment is possible only by eliminating all of the stone fragments and by eradicating UTI. A variety of operative and pharmaceutical approaches is available. Metaphylactic treatment is mandatory to prevent recurrences. The relationship between urinary stones and UTIs is well known and shows two different clinical pictures: (1) stones that develop following UTIs (infection stones) which play a key role in stone pathogenesis, and (2) stones complicated by UTIs (stones with infection) which are metabolic stones that passively trap bacteria from coexistent UTIs and may consist of calcium or non-calcium. This article presents an overview of infection stones, analyzing the epidemiology, composition, pathogenesis, diagnosis, treatment and prevention of this type of calculi.

The aim of the current study was to evaluate the use of fresh-frozen concurrently with embalmed cadavers as initial training models for flexible ureteroscopy (fURS) in a group of urologists who were inexperienced in retrograde intrarenal surgery (RIRS). Twelve urologists involved in a cadaveric fURS training course were enrolled into this prospective study. All the participants were inexperienced in fURS. Theoretical lectures and step-by-step tips and tricks video presentations on fURS were used to incorporate the technical background of the procedure to the hands-on-training course and to standardize the operating steps of the procedure. An 8-item survey was administered to the participants upon initiation and at the end of the course. Pre- and post-training scores were similar for each question. All the participants successfully completed the hands-on-training tasks. Mean pre-training duration [3.56 ± 2.0 min (range 1.21–7.46)] was significantly higher than mean post-training duration [1.76 ± 1.54 min (range 1.00–6.34)] (p = 0.008). At the end of the day, the trainers checked the integrity of the collecting system both by endoscopy and by fluoroscopy and could not detect any injury of the upper ureteral wall or pelvicalyceal structures. The functionality of the scopes was also checked, and no scope injury (including a reduction in the deflection capacity) was noted. The fURS simulation training model using soft human cadavers has the unique advantage of perfectly mimicking the living human tissues. This similarity makes this model one of the best if not the perfect simulator for an effective endourologic training.

Background Bacillus Calmette-Guérin (BCG) is considered the most effective treatment to reduce recurrence and progression of non-muscle invasive bladder cancer (NMIBC) but can induce local side effects leading to treatment discontinuation or interruption. Aim of this exploratory study is to investigate if the sequential administration of Hyaluronic acid (HA) may reduce local side effects of BCG. Methods 30 consecutive subjects undergoing BCG intravesical administration for high risk NMIBC were randomized to receive BCG only (Group A) or BCG and HA (Group B). A 1 to 10 Visual Analog Scale (VAS) for bladder pain, International Prostate Symptom Score (IPSS) and number of micturitions per day were evaluated in the two groups before and after six weekly BCG instillations. Patients were also evaluated at 3 and 6 months by means of cystostopy and urine cytology. Results One out of 30 (3,3%) patients in group A dropped out from the protocol, for local side effects. Mean VAS for pain was significantly lower in group B after BCG treatment (4.2 vs. 5.8, p = 0.04). Post vs. pre treatment differences in VAS for pain, IPSS and number of daily micturitions were all significantly lower in group B. Three patients in group A and 4 in group B presented with recurrent pathology at 6 month follow up. Conclusions These preliminary data suggest a possible role of HA in reducing BCG local side effects and could be used to design larger randomized controlled trials, assessing safety and efficacy of sequential BCG and HA administration.

We tested the effects of 5-Hz rTMS over the motor cortex in multiple sclerosis (MS) subjects complaining of lower urinary tract symptoms either in the filling or voiding phase. Our data show that motor cortex stimulation for five consecutive days over two weeks ameliorates the voiding phase of the micturition cycle, suggesting that enhancing corticospinal tract excitability might be useful to ameliorate detrusor contraction and/or urethral sphincter relaxation in MS patients with bladder dysfunction.

Background Laparoscopic radical nephrectomy (LRN) is the actual gold-standard for the treatment of clinically localized renal cell carcinoma (RCC) (cT1-2 with no indications for nephron-sparing surgery). Limited evidence is currently available on the role of robotics in the field of radical nephrectomy. The aim of the current study was to provide a systematic review of the current evidence on the role of robotic radical nephrectomy (RRN) and to analyze the comparative studies between RRN and open nephrectomy (ON)/LRN. Methods A Medline search was performed between 2000–2013 with the terms “robotic radical nephrectomy”, “robot-assisted laparoscopic nephrectomy”, “radical nephrectomy”. Six RRN case-series and four comparative studies between RRN and (ON)/pure or hand-assisted LRN were identified. Results Current literature produces a low level of evidence for RRN in the treatment of RCC, with only one prospective study available. Mean operative time (OT) ranges between 127.8-345 min, mean estimated blood loss (EBL) ranges between 100–273.6 ml, and mean hospital stay (HS) ranges between 1.2-4.3 days. The comparison between RRN and LRN showed no differences in the evaluated outcomes except for a longer OT for RRN as evidenced in two studies. Significantly higher direct costs and costs of the disposable instruments were also observed for RRN. The comparison between RRN and ON showed that ON is characterized by shorter OT but higher EBL, higher need of postoperative analgesics and longer HS. Conclusions No advantage of robotics over standard laparoscopy for the treatment of clinically localized RCC was evidenced. Promising preliminary results on oncologic efficacy of RRN have been published on the T3a-b disease. Fields of wider application of robotics should be researched where indications for open surgery still persist.

Background Aim of this study was to make a comparison between penile cuff test (PCT) and standard pressure-flow study (PFS) in the preoperative evaluation of patients candidates for trans-urethral resection of prostate (TURP) for benign prostatic obstruction (BPO). Methods We enrolled male patients with lower urinary tract symptoms candidates for TURP. Each of them underwent a PCT and a subsequent PFS. A statistical analysis was performed: sensitivity (SE), specificity (SP), positive predictive value (PPV), negative predictive value (NPV), likelihood ratio and ratio of corrected classified were calculated. Fisher exact test was used to evaluate relationships between PCT and maximal urine flow (Qmax): a p-value

Objectives: To compare the concordance of prostate cancer (PCa) laterality between the extended transperineal (TP) or transrectal (TR) prostate biopsy (BP) and radical prostatectomy (RP) specimens. To identify predictors of laterality agreement between BP and RP. Materials and Methods: Data from 533 consecutive patients with PCa (278 TP and 255 TR-diagnosed) treated with RP were analyzed. A 12-core technique was used for both TP and TR biopsies. Additional cores were obtained when necessary. Results: Overall, the percentage of agreement of PCa laterality between BP and RP was 60% (K = 0.27, p < 0.001). However, the RP confirmation of unilaterality at BP was obtained in just 33% of the cases. Considering the concordance on bilaterality as the “target” of our analysis, the sensitivity and specificity were 54.3% and 98.2%, respectively, with TP and 47.5% and 92.5%, respectively with TR. Focusing on patients with unilaterality at biopsy, none of the evaluated preoperative variables (biopsy technique, age, total positive biopsy cores, PSA, prostate volume, Gleason score on biopsy) were able to predict RP bilaterality in the multivariate analyses. Conclusions: Most of the patients with unilateral involvement at BP harbored bilateral PCa after RP. TR and TP biopsy showed no difference in their capacity to predict the concordance of tumor laterality at RP. None of the preoperative evaluated variables can predict the tumor laterality at RP. Using BP unilaterality to include patients in focal therapy (FT) protocols may hinder the oncologic efficacy of FT.

Laparoscopic nephrectomy (LN) in end-stage autosomic-dominant polycystic kidney disease (ADPKD) requires a large abdominal incision for the specimen extraction. The objective of this study was to describe our technique of LN for end-stage ADPKD followed by morcellation (LNM) of the specimen and extraction through a minimal abdominal incision. The medical records of 19 consecutive patients who underwent pretransplant LNM between 2008 and 2011 by a single experienced laparoscopic surgeon were analyzed. Morcellation was performed with the Gynecare Morcellex™ Tissue morcellator, Ethicon. All cases but one were completed laparoscopically. Mean specimen weight was 1,026.8 g. Mean duration of the procedure, estimated blood loss, and hospital stay were 131.3 min, 52.1 ml, and 7.9 days, respectively. Specimens were extracted through a 12-mm trocar in 10/18 patients and through a 3-cm incision in 9/18 cases. Postoperatively, three complications were observed (Clavien grades II, I, and II). The only case of incisional hernia was observed in the converted procedure. Major limitation of the study is its retrospective design. In our preliminary series and in the hands of a very experienced laparoscopist, LNM for ADPKD appears as a modern, mini-invasive, and safe technique. Specimen’s extraction through a small abdominal incision reduces postoperative pain and incisional hernias and guarantees the final cosmetic result of laparoscopy. The reduced overall morbidity could reduce the period between nephrectomy and transplantation.

Despite the growth of the digital era, rapid spread of information, and real-time communication, there are several urologists throughout the world who do not have access to urological scientific programs, academic training programs, or memberships to well-established urological organizations, associations, and societies. The International Young Urological Association (IYUA) is a non-profit organization that was created to specifically address and facilitate access for urologists that for geopolitical, economical, or other reasons would not otherwise have these opportunities available to them. The IYUA's non-competitive nature allows for urologists to use the IYUA as an initial platform to network with globally established organizations to deliver scientific training programs, courses, and meetings in less common locations. It is our objective to demonstrate the IYUA's mission and facets that may contribute to the increased academic and scientific education of professionals in Urology where the access to these resources can be challenging.

This review summarizes recent literature on advances regarding renal and ureteral calculi, with particular focus in areas of recent advances in the overall field of urolithiasis. Clinical management in everyday practice requires a complete understanding of the issues regarding metabolic evaluation and subgrouping of stone-forming patients, diagnostic procedures, effective treatment regime in acute stone colic, medical expulsive therapy, and active stone removal. In this review we focus on new perspectives in managing nephrolitihiasis and discuss recentadvances, including medical expulsive therapy, new technologies, and refinements of classical therapy such as shock wave lithotripsy, give a fundamental modification of nephrolithiasis management. Overall, this field appears to be the most promising, capable of new developments in ureterorenoscopy and percutaneous approaches. Further improvements are expected from robotic-assisted procedures, such as flexible robotics in ureterorenoscopy.

To present a critical overview of the current literature on the role of laparoscopy for the surgical treatment of patients with large prostatic adenomas.A MedLine search for peer-reviewed studies on laparoscopic simple prostatectomy (LSP) was performed. The clinical studies that reported most of the following information were included: number of patients, prostate volume, operative time, blood loss, hospital stay, and the duration of catheterization, as well as functional outcomes and complications. Articles reporting a mean total prostate volume of80 mL or a mean prostatic adenoma of60 mL were excluded. The review was performed according to the PRISMA statement.Fourteen articles on LSP were included in this systematic review with a total of 626 patients treated. Both transperitoneal and extraperitoneal approaches, as well as transvesical and transcapsular routes, have been described. Eleven articles were case-series and three were comparative retrospective nonrandomized studies. When compared with open simple prostatectomy (OP), LSP is associated with a less blood loss and a reduced irrigation requirement, a shorter postoperative catheterization period, and a shorter hospital stay, at the expense of an extended operative time. The limited number of patients treated, the selection biases due to the retrospective nature of several published articles on LSP, and the short follow-up periods are evident limits of the literature. I-square test demonstrated a high heterogeneity (93%) and consequently a high variability in the intervention effects in terms of maximum urinary flow rate (Qmax).Even if LSP seems feasible and safe, there is still limited evidence regarding its long-term outcomes compared with OP.

Introduction: Previous measurement of the male external urethral sphincter complex (EUSC) length by magnetic resonance imaging and urethral pressure profilometry did not consider the intraprostatic portion, although its role for urinary continence has been demonstrated. The aim of our study was to verify the feasibility of a morphological evaluation of the EUSC by transrectal ultrasound (TRUS). Materials and Methods: Data from 52 men that underwent TRUS were prospectively collected. The EUSC was identified in the midline sagittal plane. Total and intraprostatic EUSC length and prostate volume were measured. Results: EUSC appears as a hypoechoic area surrounding the urethra. The proximal end was identified between the verumontanum and the prostate apex by the net change in prostate echo patterns, while the distal end was identified by voluntary contraction of the external anal sphincter. Mean total and intraprostatic EUSC lengths were 20.17 and 3.78 mm, respectively. Total EUSC length presented a weak correlation with prostate volume (r = 0.41; p = 0.003), while the intraprostatic portion had a stronger correlation (r = 0.60; p = 0.001). Conclusions: The evaluation of the EUSC is feasible by TRUS, and length measurement should include the intraprostatic portion. Potential clinical application should be the preoperative assessment of the risk of urinary incontinence in men undergoing radical prostatectomy.

PURPOSE: To evaluate the accuracy of contrast-enhanced (18)F-choline PET/CT in restaging patients with prostate cancer after radical prostatectomy in relation to PSA, PSA velocity (PSAve) and PSA doubling time (PSAdt). METHODS: PET/CT was performed in 49 patients (age range 58-87 years) with rising PSA (mean 4.13 ng/ml) who were divided in four groups according to PSA level: 4 ng/ml. PSAve and PSAdt were measured. PET and CT scans were interpreted separately and then together. RESULTS: PET/CT diagnosed relapse in 33 of the 49 patients (67%). The detection rates were 20%, 55%, 80% and 87% in the PSA groups 4 ng/ml, respectively. PET/CT was positive in 7 of 18 patients (38.9%) with a PSA 2 ng/ml. PET/CT was positive in 7 of 25 patients (84%) with PSAdt 6 months, and was positive in 26 of 30 patients (86%) with a PSAve >2 ng/ml per year, and in 7 of 19 patients (36.8%) with PSAve 2 ng/ml, PSAdt 2 ng/ml per year. CT is useful for detecting bone metastases that are not (18)F-choline-avid. The use of intravenous contrast agent seems unnecessary.

Introduction Peyronie's disease (PD) is a connective tissue disorder of tunica albuginea (TA), a thick fibrous sheath surrounding the corpora cavernosa of the penis. Relatively, little is known about the disease itself. Aim To investigate whether the apoptosis cascade in degenerated and macroscopically deformed TA from men with PD is activated through the extrinsic pathway, by assessing the immunoexpression of tumor necrosis factor‐related apoptosis‐inducing ligand (TRAIL) and its death receptor, DR5. Methods TA plaques from 15 men with PD and from four unaffected men were processed for TRAIL and DR5 immunohistochemistry and Western blot analysis. Main Outcome Measures A greater understanding of the pathophysiology of PD through a molecular approach, to gain insights that may lead to novel forms of treatment. Results Activation of the apoptosis mechanisms through the extrinsic pathway was demonstrated by TRAIL and DR5 overexpression in fibroblasts and myofibroblasts from affected TA. Conclusion The finding that apoptosis activation in TA plaques occurs, at least in part, via the extrinsic pathway may help devise novel therapeutic options for these patients.

Objectives To evaluate the prevalence and short-term follow-up of focal proliferative atrophy lesions, either with or without the presence of inflammation (PIA/PA), and its correlation with the PSA levels, focusing on the prostate biopsy cores that test negative for prostate adenocarcinoma (PCa). Methods Five hundred fifty consecutive patients who had undergone a transrectal ultrasound-guided transperineal prostate biopsy were evaluated retrospectively for the presence and follow-up of focal proliferative atrophy lesions. PIA/PA were defined according to De Marzo. The prevalence of atrophy in PCa and negative biopsy cores was compared by means of χ2. After logarithmic transformations of the PSA values, t-test and ANOVA were applied for the comparison of the means. Incidence of newly diagnosed PCa during follow-up (mean 33.7 months) in patients with or without focal proliferative atrophy was compared by means of χ2. Results A focal atrophic lesion resulted in 161/339 negative biopsies. PIA was observed in 93/161 patients (57.8%), while PA was observed in the remaining 68/161 (42.2%). Among the negative biopsy cases, the difference in PSA values were not statistically significant according to the presence or absence of atrophy (P = 0.120). The group of negative biopsies with PIA was similar in terms of PSA characteristics with the benign (PA P = 0.738; non-atrophy P = 0.342), and cancer subgroups (P = 0.094); 245/339 (72.3%) patients were successfully followed-up. Biopsy was repeated in 24/71 (33.8%) patients with PIA, in 14/50 (28%) with PA and in 27/124 (21.7%) with no atrophy lesions at initial biopsy. The incidence of newly diagnosed PCa in the 3 groups was not statistically different (χ2, P = 0.81). Conclusions Focal proliferative atrophy lesions are a common finding in biopsy specimens negative for PCa. Patients with negative biopsy associated with PIA presented similar PSA characteristics as patients with biopsy-proven PCa. However, the incidence of PCa at short-term follow-up did not differ significantly between patients with PIA, PA, or no atrophic lesions at initial biopsy. Based on our findings, early repeat biopsy does not seem to be necessary after an initial diagnosis of PIA/PA, although a longer follow-up is mandatory for definitive conclusions.
