RESUMO
Context: Intermittent self-dilatation (ISD) is a therapeutic strategy used to stabilise a urethral stricture and postpone or avoid further treatment. Adding corticosteroids to this mode of management might further enhance its outcomes by downregulation of collagen deposition and excessive scar tissue formation. Objective: To explore whether a course of ISD with topical corticosteroids is superior at stabilising urethral stricture disease in men and improving functional outcomes over a course of ISD alone. Evidence acquisition: This systematic review and meta-analysis was undertaken by the European Association of Urology Urethral Strictures Guideline Panel according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines (CRD42021256744). The primary benefit outcome was successful stabilisation of the urethral stricture. Treatment-related complications were the primary harm outcome. Evidence synthesis: In total, 978 records were screened for eligibility, ultimately leading to five included studies, all randomised controlled trials, comprising 250 patients, of whom 124 underwent a course of ISD with corticosteroids and 126 underwent a course of ISD alone, all after direct vision internal urethrotomy (DVIU). Successful stabilisation of the stricture was achieved in 77% and 64% of patients in the group with and without corticosteroids, respectively (pâ¯=â¯0.04). No extra complications related to the addition of corticosteroids to the ISD regimen were reported. The risk of bias of the included studies was generally unclear to high. Conclusions: Based on the currently available data, a course of ISD with topical corticosteroids appears to be safe and superior at stabilising a urethral stricture after DVIU in the short term to a course of ISD alone. However, given the unclear to high risk of bias in the included studies, further high-quality studies are needed to fully underpin this. Patient summary: This study shows that addition of topical corticosteroids to intermittent self-dilatation after direct vision internal urethrotomy can better stabilise the stricture in the short term.
RESUMO
Objective: To assess the diagnostic accuracy and intra-observer agreement of endoscopic stone recognition (ESR) compared with formal stone analysis. Introduction: Stone analysis is a corner stone in the prevention of stone recurrence. Although X-ray diffraction (XRD) and infrared spectroscopy are the recommended techniques for reliable formal stone analysis, this is not always possible, and the process takes time and is costly. ESR could be an alternative, as it would give immediate information on stone composition. Materials and Methods: Fifteen endourologists predicted stone composition based on 100 videos from ureterorenoscopy. Diagnostic accuracy was evaluated by comparing the prediction from visual assessment with stone analysis by XRD. After 30 days, the videos were reviewed again in a random order to assess intra-observer agreement. Results: The median diagnostic accuracy for calcium oxalate monohydrate was 54% in questionnaire 1 (Q1) and 59% in questionnaire 2 (Q2), whereas calcium oxalate dihydrate had a median diagnostic accuracy of 75% in Q1 and 50% in Q2. The diagnostic accuracy for calcium hydroxyphosphate was 10% in Q1 and 13% in Q2. The median diagnostic accuracy for calcium hydrogen phosphate dihydrate and calcium magnesium phosphate was 0% in both questionnaires. The median diagnostic accuracy for magnesium ammonium phosphate was 20% in Q1 and 40% in Q2. The median diagnostic accuracy for uric acid was 22% in both questionnaires. Finally, there was a diagnostic accuracy of 60% in Q1 and 80% in Q2 for cystine. The intra-observer agreement ranged between 45% and 72%. Conclusion: Diagnostic accuracy of ESR is limited and intra-observer agreement is below the threshold of acceptable agreement.

CONTEXT: Urethral stricture management guidelines are an important tool for guiding evidence-based clinical practice. OBJECTIVE: To present a summary of the 2021 version of the European Association of Urology (EAU) guidelines on management of urethral strictures in females and transgender patients. EVIDENCE ACQUISITION: The panel performed a literature review on these topics covering a time frame between 2008 and 2018 and used predefined inclusion and exclusion criteria for study selection. Key papers beyond this time period could be included as per panel consensus. A strength rating for each recommendation was added based on the review of the available literature and after panel discussion. EVIDENCE SYNTHESIS: Management of urethral strictures in females and transgender patients has been described in a few case series in the literature. Endoluminal treatments can be used for short, nonobliterative strictures in the first line. Repetitive endoluminal treatments are not curative. Urethroplasty encompasses a multitude of techniques and adaptation of the technique to the local conditions of the stricture is crucial to obtain durable patency rates. CONCLUSIONS: Management of urethral strictures in females and transgender patients is complex and a multitude of techniques are available. Selection of the appropriate technique is crucial and these guidelines provide relevant recommendations. PATIENT SUMMARY: Although different techniques are available to manage narrowing of the urethra (called a stricture), not every technique is appropriate for every type of stricture. These guidelines, developed on the basis of an extensive literature review, aim to guide physicians in selecting the appropriate technique(s) to treat a specific type of urethral stricture in females and transgender patients. TAKE HOME MESSAGE: Although different techniques are available to manage urethral strictures, not every technique is appropriate for every type of stricture. Management of urethral strictures in females and transgender patients is complex and a multitude of techniques are available. Selection of the appropriate technique is crucial and these guidelines provide relevant recommendations.

PURPOSE: The benefits and harms of the available types of surgical management for lichen sclerosus-related (LS) strictures remain unclear and, thus, clear and robust clinical practice recommendations cannot be given. MATERIALS AND METHODS: To assess the role of single-stage OMGU in the management of LS strictures and explore how its benefits and harms compare with the alternative management options. Medline, Embase and Cochrane controlled trial databases (CENTRAL, CDSR) were systematically searched. Randomized (RCTs) and nonrandomized studies (NRCSs) comparing single-stage OMGU with other surgical management options for LS strictures and single-arm studies on single-stage OMGU were included. Risk of bias (RoB) was assessed. RESULTS: Of the 1912 abstracts identified, 15 studies (1 NRCS and 14 single-arm studies) were included, recruiting in total 649 patients. All studies were at high RoB. In the only NRCS available, stricture-free rate (SFR) for single-stage and staged OMGU was 88% vs 60%, respectively (p = 0.05), at a mean follow-up of 66.5 months. SFR range for single-stage OMGU in single-arm studies was 65-100% (mean/median follow-up, 12-59 months). Single-stage OMGU had low complication rates and beneficial impact on LUTS and QoL. CONCLUSIONS: The present SR highlights the methodological limitations of the available literature. In the absence of adverse local tissue conditions, and taking into consideration benefit-harm balance and surgeon's skills and expertise, single-stage OMGU can be justified in patients with LS strictures.

OBJECTIVE: To present a summary of the 2021 version of the European Association of Urology (EAU) guidelines on management of male urethral stricture disease. EVIDENCE ACQUISITION: The panel performed a literature review on these topics covering a time frame between 2008 and 2018, and used predefined inclusion and exclusion criteria for the literature to be selected. Key papers beyond this time period could be included as per panel consensus. A strength rating for each recommendation was added based on a review of the available literature and after panel discussion. EVIDENCE SYNTHESIS: Management of male urethral strictures has extensively been described in literature. Nevertheless, few well-designed studies providing high level of evidence are available. In well-resourced countries, iatrogenic injury to the urethra is one of the most common causes of strictures. Asymptomatic strictures do not always need active treatment. Endoluminal treatments can be used for short, nonobliterative strictures at the bulbar and posterior urethra as first-line treatment. Repetitive endoluminal treatments are not curative. Urethroplasty encompasses a multitude of techniques, and adaptation of the technique to the local conditions of the stricture is crucial to obtain durable patency rates. CONCLUSIONS: Management of male urethral strictures is complex, and a multitude of techniques are available. Selection of the appropriate technique is crucial, and these guidelines provide relevant recommendations. PATIENT SUMMARY: Injury to the urethra by medical interventions is one of the most common reasons of male urethral stricture disease in well-resourced countries. Although different techniques are available to manage urethral strictures, not every technique is appropriate for every type of stricture. These guidelines, developed based on an extensive literature review, aim to guide physicians in the selection of the appropriate technique(s) to treat a specific type of urethral stricture.

CONTEXT: Urethral stricture management guidelines are an important tool for guiding evidence-based clinical practice. OBJECTIVE: To present a summary of the 2021 European Association of Urology (EAU) guidelines on diagnosis, classification, perioperative management, and follow-up of male urethral stricture disease. EVIDENCE ACQUISITION: The panel performed a literature review on the topics covering a time frame between 2008 and 2018, and using predefined inclusion and exclusion criteria for the literature. Key papers beyond this time period could be included if panel consensus was reached. A strength rating for each recommendation was added based on a review of the available literature after panel discussion. EVIDENCE SYNTHESIS: Routine diagnostic evaluation encompasses history, patient-reported outcome measures, examination, uroflowmetry, postvoid residual measurement, endoscopy, and urethrography. Ancillary techniques that provide a three-dimensional assessment and may demonstrate associated abnormalities include sonourethrography and magnetic resonance urethrogram, although these are not utilised routinely. The classification of strictures should include stricture location and calibre. Urethral rest after urethral manipulations is advised prior to offering urethroplasty. An assessment for urinary extravasation after urethroplasty is beneficial before catheter removal. The optimal time of catheterisation after urethrotomy is <72 h, but is unclear following urethroplasty and depends on various factors. Patients undergoing urethroplasty should be followed up for at least 1 yr. Objective and subjective outcomes should be assessed after urethral surgeries, including patient satisfaction and sexual function. CONCLUSIONS: Accurate diagnosis and categorisation is important in determining management. Adequate perioperative care and follow-up is essential for achieving successful outcomes. The EAU guidelines provide relevant evidence-based recommendations to optimise patient work-up and follow-up. PATIENT SUMMARY: Urethral strictures have to be assessed adequately before planning treatment. Before surgery, urethral rest and infection prevention are advised. After urethral surgery, x-ray dye tests are advised before removing catheters to ensure that healing has occurred. Routine follow-up is required, including patient-reported outcomes. These guidelines aim to guide doctors in the diagnosis, care, and follow-up of patients with urethral stricture.

Background: 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.

CONTEXT: Four techniques for graft placement in one-stage bulbar urethroplasty have been reported: dorsal onlay (DO), ventral onlay (VO), dorsolateral onlay (DLO), and dorsal inlay (DI). There is currently no systematic review in the literature comparing these techniques. OBJECTIVE: To assess if stricture recurrence and secondary outcomes vary between the four techniques and to assess if one technique is superior to any other. EVIDENCE ACQUISITION: The EMBASE, MEDLINE, and Cochrane Systematic Reviews-Cochrane Central Register of Controlled Trials (CENTRAL; Cochrane HTA, DARE, HEED) databases and ClinicalTrials.gov were searched for publications in English from 1996 onwards. Randomised controlled trials (RCTs), nonrandomised comparative studies (NRCSs), observational studies (cohort, case-control/comparative, single-arm), and case series with ≥20 adult male participants were included. EVIDENCE SYNTHESIS: A total of 41 studies were included involving 3683 patients from one RCT, four NRCSs, and 36 case series. Owing to the overall low quality of the evidence, a narrative synthesis was performed. CONCLUSIONS: No single technique appears to be superior to another for bulbar free graft urethroplasty. Both DO and VO are suitable for bulbar augmentation urethroplasty, with a ≤20% recurrence rate over medium-term follow-up. No recommendations can be made regarding DI or DLO techniques owing to the paucity of evidence. Secondary outcomes including sexual function, and complications are infrequently reported. Recurrence rates deteriorate in the long term for both DO and VO procedures. PATIENT SUMMARY: We reviewed the evidence for four different skin-graft techniques used to repair narrowing of a section of the urethra (bulbar urethra, under the scrotum and perineum) in men. Two of the techniques seem to give consistent results, with recurrence rates lower than 20%. Recurrence rates increase over time, so patients should continue to monitor their symptoms. There is poorer reporting of other outcomes such as sexual function, urinary symptoms, and complications, and it is possible that these occur more frequently than the current data suggest.

PURPOSE: To evaluate the feasibility of measuring the intrapelvic pressure (IPP) during f-URS with a wire including a pressure sensor and to assess IPP profiles during the procedure. METHODS: Patients undergoing f-URS for stone disease were recruited. A wire with pressure sensor was placed in the renal cavities to measure IPP. For these cases, either no ureteral access sheath (UAS) or 10/12 or 12/14-Fr UASs were used according to surgeon discretion. Irrigation was ensured by a combination of a continuous pressure generator set at 80 cmH2O and a hand-assisted irrigation system providing on-demand forced irrigation to provide proper visibility. Pressures were monitored in real time and recorded for analysis. RESULTS: Four patients undergoing five f-URS were included. IPP monitoring was successful in all patients. Mean baseline IPP was 6 cmH2O. During f-URS with only the endoscope in the renal cavities and irrigation pressure set at 80 cmH2O without any forced irrigation, the mean IPP was 63 cmH2O. Mean IPP during laser lithotripsy with the use of on-demand forced irrigation was 115.3 cmH2O. The maximum pressure peaks recorded during this therapeutic period using forced irrigation ranged from 289.3 to 436.9 cmH2O. CONCLUSION: High IPP levels may be achieved during f-URS with on-demand irrigation systems. The impact of these high pressures on the risk of complications and long-term consequences still need to be evaluated adequately. But, in this preliminary pilot study, IPP could be reliably and conveniently monitored and recorded using a wire with a digital pressure sensor.

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.

INTRODUCTION: Percutaneous nephrolithotomy (PNL) can be performed either in prone or supine position. This study aimed at gathering together randomized controlled trials (RCTs) comparing efficacy and safety between prone and supine PNL. EVIDENCE ACQUISITION: Systematic review of literature was conducted using the Scopus, Medline and Web of Science databases. Study selection, data extraction and quality assessment were independently assessed by two authors. Meta-analysis was performed with Review Manager 5.3. Sensitivity analyses were performed to exclude studies with high risk of bias. EVIDENCE SYNTHESIS: Pooled data from 12 studies including 1290 patients were available for analysis. Only one study was found to have overall low risk of bias. Significantly shorter operative time was found in favor of supine PNL (mean difference 13 minutes, 95% confidence interval [CI]: 3.4-22.7; P<0.01). Stone-free rate (SFR)≥14 days after surgery was significantly higher in prone PNL (odds ratio [OR]=2.15, 95% CI: 1.07-4.34; P=0.03). Significantly higher fever rate was found in prone PNL (OR=1.60, 95% CI: 1.03-2.47; P=0.04). Overall SFR, hospital stay length, complications rate, transfusions rate and blood loss, as well as non-lower calyx puncture rate, puncture attempts and tubeless intervention rate did not differ between prone and supine PNL (P>0.05). CONCLUSIONS: Efficacy of PNL seems balanced between prone and supine position, with comparable overall SFR and shorter operative time in favor of supine PNL. Safety of PNL appears in favor of supine PNL, with lower fever rate. Because of study heterogeneity and possible risks of outcome bias, results from this study should be interpreted with caution. Altogether, both prone and supine PNL account for appropriate therapy options.

CONTEXT: Surgical repair of a vesicovaginal fistula (VVF) has been described extensively in the literature for several decades. Advances in robotic repair have been adopted since 2005. OBJECTIVE: A consensus review of existing data based on published case series, expert opinion, and a survey monkey. EVIDENCE ACQUISITION: This document summarizes the consensus group meeting and survey monkey results convened by the European Association of Urology Robotic Urology Section (ERUS) relating to the robotic management of VVF. EVIDENCE SYNTHESIS: Current data underline the successful robotic repair of supratrigonal nonobstetric VVF. The panel recommends preoperative marking of the fistula by a guidewire or ureteral catheter, and placement of a protective ureteral JJ stent. An extravesical robotic approach usually provides a good anatomic view for adequate and wide dissection of the vesicovaginal space, as well as bladder and vaginal mobilization. Careful sharp dissection of fistula edges should be performed. Tension-free closure of the bladder is of utmost importance. Tissue interposition seems to be beneficial. The success rate of published series often reaches near 100%. An indwelling bladder catheter should be placed for about 10 d postoperatively. CONCLUSIONS: When considering robotic repair for VVF, it is essential to establish the size, number, location, and etiology of the VVF. Robotic assistance facilitates dissection of the vesicovaginal space, harvesting of a well-vascularized tissue flap, and a tension-free closure of the bladder with low morbidity for the patient being operated in the deep pelvis with delicate anatomical structures. PATIENT SUMMARY: Robotic repair of a vesicovaginal fistula can be applied safely with an excellent success rate and very low morbidity. This confirms the use of robotic surgery for vesicovaginal fistula repair, which is recommended in a consensus by the European Association of Urology Robotic Section Scientific Working Group for reconstructive urology.

OBJECTIVES: To explore the differences between primary and redo urethroplasty and to directly compare according stricture-free survival (SFS). Materials and Methods. Data of all male patients who underwent urethroplasty at Ghent University Hospital were collected between 2000 and 2018. Exclusion criteria for this analysis were age <18 years and follow-up <1 year. Two patient groups were created for further comparison: the primary urethroplasty (PU) group (no previous urethroplasty) and redo urethroplasty (RU) group (≥1 previous urethroplasty), irrespective of prior endoscopic treatments. A comparison between groups was performed using the Mann-Whitney U test and Fisher's Exact test. SFS was calculated using Kaplan-Meier statistics. A functional definition of failure, being the need for further urethral manipulation, was used. Uni- and multivariate Cox regression analyses were performed on the entire patient cohort. RESULTS: 805 patients were included. Median (IQR) follow-up of the PU (n = 556) and RU (n = 556) and RU (p=0.1). The RU group involved more penile strictures (p=0.1). The RU group involved more penile strictures (p=0.1). The RU group involved more penile strictures (p=0.1). The RU group involved more penile strictures (p=0.1). The RU group involved more penile strictures (p=0.1). The RU group involved more penile strictures (p=0.1). The RU group involved more penile strictures (p=0.1). The RU group involved more penile strictures (p=0.1). The RU group involved more penile strictures (. CONCLUSIONS: Several differences between primary and redo urethroplasties exist. Redo urethroplasty entails a distinct patient population to treat and is, in general, associated with lower stricture-free survival than primary urethroplasty, although more homogeneous series are required to corroborate these results. Prior urethroplasty and diabetes are independent risk factors for urethroplasty failure.

INTRODUCTION: The endoscopic stone treatment step 1 (EST s1) protocol has been developed after 2 years of collaborative work between different European Association of Urology (EAU) sections. OBJECTIVES: In this study, we added construct validity evidence to the EST s1 curriculum. MATERIALS AND METHODS: The EST-s1 curriculum includes four standardized tasks: flexible cystoscopy, rigid cystoscopy, semi-rigid URS and flexible URS. Validation was performed during the annual 2016 EUREP meeting in Prague. 124 participants provided information on their endoscopic logbook and carried out these 4 tasks during a DVD recorded session. Recordings were anonymized and blindly assessed independently by five proctors. Inter-rater reliability was checked on a sample of five videos by the calculation of intra-class correlation coefficient. Task-specific clinical background of participants was correlated with their personal performance on the simulator. Breakpoint analysis was used to define the minimum number of performed cases, to be considered "proficient". "Proficient" and "Non-proficient" groups were compared for construct validity assessment. Likert scale-based questionnaires were used to test content and to comment on when the EST-s1 exams should be undertaken within the residency program. RESULTS: 124 participants (105 final-year residents and 19 faculty members) took part in this study. The breakpoint analysis showed a significant change in performance curve at 36, 41, 67 and 206 s, respectively, corresponding to 30, 60, 25 and 120 clinical cases for each of the 4 tasks. EST-s1 was scored as a valid training tool, correctly representing the procedures performed in each task. Experts felt that this curriculum is best used during the third year of residency training. CONCLUSION: Our validation study successfully demonstrated correlation between clinical expertise and EST-s1 tasks, adding construct validity evidence to it. Our work also demonstrates the successful collaboration established within various EAU sections.

With an increase in the number of ureteroscopy (URS) procedures, URS is now performed more widely and is becoming a standard procedure for all urologists. There is also a rise in the complexity of these procedures and URS is now offered for treatment of stones as well as for diagnosis and treatment of urothelial tumours. We wanted to provide a 'pictorial review' of the 'tips and tricks' of URS, as the finer and technical details are often easier to understand and remember with images rather than through textual explanations.
RESUMO
INTRODUCTION: Kidney transplantation (KT) is the gold-standard treatment for end-stage renal disease (ESRD) in children. Robot-assisted kidney transplantation (RAKT) in adults is becoming increasingly common with potentially improved morbidity compared with open KT. The study objective was to evaluate feasibility and outcomes of RAKT in children. PATIENTS & METHODS: An 8-years-old boy with ESRD received a kidney transplant from his mother. Simultaneously in two operation theatres, the boy underwent single-port (GelPOINT®) right laparoscopic nephro-ureterectomy (LNU), and his mother underwent robot-assisted left donor nephrectomy (RADN).Two full surgical teams were operating at the same time. Subsequently, the boy underwent RAKT, introducing the graft through the GelPOINT®. RESULTS: Total operative time for LNU, RADN, and RAKT was 180, 140, and 195 min, respectively, with warm, cold, and rewarming ischemia times 1.5, 200, and 47 min, respectively. Blood loss was 300, 20, and 50 cc, respectively. No intraoperative complications were noted. Convalescence of both donor and recipient was uneventful, with good kidney function at 1-year follow-up. CONCLUSION: RAKT in children is technically feasible and safe, resulting in excellent graft function. Concomitant nephrectomy can be done laparoscopically through the single-site GelPOINT®. An experienced RAKT team with the full support of pediatric nephrologists is mandatory.

INTRODUCTION: Glans resurfacing has been suggested as a treatment option for the surgical management of superficial penile cancer (Tis, Ta, T1aG1, T1aG2). In this article we describe in detail the glans resurfacing technique with skin graft for penile cancer in a video presentation and we review the current knowledge of the literature. MATERIAL AND METHODS: The procedure is described in a stepwise fashion. Initially the patient is circumcised. The glans is marked in quadrants and completely stripped by dissecting and removing the epithelium and subepithelium layer of the glans. Deep spongiosal biopsies are taken to exclude invasion. Each quadrant is sent separately for biopsy. The surface of the graft size needed is estimated. A partial thickness skin graft is harvested from the thigh with a dermatome. The skin graft is then fenestrated. The graft is rolled over the glans and quilted with multiple sutures. A silicone 16F Foley catheter and a suprapubic catheter are placed. The penis is dressed with multiple gauzes and compressed with an elastic band. RESULTS: The patient is discharged the next day. The dressing and Foley catheter are removed in 7 days. The patient continues to use the suprapubic catheter for 7 more days. The patient refrains from any sexual activity for 6 weeks and is closely followed. CONCLUSIONS: Glans resurfacing is an emerging new appealing surgical technique that is already a recommendation in the EAU guidelines for the treatment of premalignant and superficial penile lesions. The overall satisfaction rate and recovery of the sexual function are acceptable, and it can be considered an ideal procedure to treat superficial penile cancer.

INTRODUCTION: Robot-assisted partial nephrectomy (RAPN) is increasingly used for the surgical management of renal masses. Aim of this study was to analyze the available literature regarding the outcomes of RAPN compared to those of open partial nephrectomy (OPN). EVIDENCE ACQUISITION: A literature search was performed up to October 2018 using PubMed, MEDLINE and Embase. Article selection followed the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) principles and Population, Intervention, Comparator, Outcomes (PICO) methodology was used. Population (P) was patients with renal masses who underwent RAPN (I). RAPN was compared with OPN (C). Outcomes of interest were perioperative, oncological and functional outcomes of both surgical procedures (O). Inclusion criteria were: randomized controlled studies andobservational cohort studies comparing RAPN versus OPN, which reported at least one outcome of interest. EVIDENCE SYNTHESIS: Twenty-two manuscripts met our inclusion criteria and were included in the systematic review. RAPN was superior to OPN in terms of complication rate in 11 studies while similar results were observed in 9 studies. Positive surgical margins were similar in 13 studies while RAPN had lower surgical margins in 6 studies. Operative and warm ischemia times were longer in OPN in 13 and 10 studies, respectively. Seventeen and 19 studies showed that estimated blood loss and length of hospital stay were higher in RAPN. Estimated glomerular filtration rate decline and chronic kidney disease upstaging decline were similar in the majority of studies. CONCLUSIONS: Current evidence demonstrate that RAPN is a reasonable alternative to OPN with regard to oncological and early functional outcomes with a straightforward advantage of improved perioperative morbidity, as expected by minimally invasive techniques. Nevertheless, there is still a great need for well-designed randomized studies with an extended follow-up.
