RESUMO
OBJECTIVE: To perform an external validation of this RC-pentafecta. METHOD: Between January 2014 and December 2019, 104 consecutive patients who underwent RARC with ICUD within 6 urological centers were analyzed retrospectively. Patients who simultaneously demonstrated negative soft tissue surgical margins (STSMs), a lymph node (LN) yield ≥ 16, absence of major (Clavien-Dindo grade III-V) 90-day postoperative complications, absence of UD-related long-term sequelae, and absence of 12-month clinical recurrence were considered to have achieved RC-pentafecta. A multivariable logistic regression model was used to measure predictors for achieving RC-pentafecta. We analyzed the influence of this RC-pentafecta on survival, and the impact ofthe surgical experience. RESULTS: Since 2014, 104 patients who had completed at least 12 months of follow-up were included. Over a mean follow-up of 18 months, a LN yield ≥ 16, negative STSMs, absence of major complications at 90 days, and absence of UD-related surgical sequelae and clinical recurrence at ≤ 12 months were observed in 56%, 96%, 85%, 81%, and 91% of patients, respectively, resulting in a RC-pentafecta rate of 39.4%. Multivariate analysis showed that age was an independent predictor of pentafecta achievement (odds ratio [OR], 0.96; 95% confidence interval [CI], 0.90. 0.99; p = 0.04). The surgeon experience had an impact on the validation of the criteria. CONCLUSION: This study confirmed that the RC-pentafecta is reproducible and could be externally used for the outcome assessment after RARC with ICUD. Therefore, the RC-pentafecta could be a useful tool to assess surgical success and its impact on different outcomes.

PURPOSE: Studies exploring the association of cigarette smoking and long-term survival outcomes following radical cystectomy have yielded mixed results. We performed a systematic review and meta-analysis to investigate the impact of tobacco smoking exposure, duration, intensity and cessation on response to neoadjuvant chemotherapy and long-term survival outcomes in patients undergoing radical cystectomy for bladder cancer. MATERIALS AND METHODS: We systematically searched PubMed®, MEDLINE®, Embase® and Cochrane® Library databases for original articles published before April 2019. Primary end points were neoadjuvant chemotherapy response, overall and cancer specific mortality, and recurrence-free survival after radical cystectomy. Observational studies reporting Cox proportional hazards regression or logistic regression analysis were independently screened. Available multivariable hazard ratios and corresponding 95% CIs were included in the quantitative analysis. Sensitivity analyses were performed as appropriate. A risk of bias assessment was completed for nonrandomized studies. RESULTS: Our electronic search identified a total of 649 articles. After a detailed review we selected 17 studies that addressed the impact of smoking status on survival outcomes in 13,777 patients after radical cystectomy for bladder cancer. Pooled meta-analysis revealed that active smokers have an increased risk of overall mortality (HR 1.21, 95% CI 1.08-1.36; p=0.001, I2=0%), cancer specific mortality (HR 1.24, 95% CI 1.13-1.36; p <0.00001, I2=0%) and bladder cancer recurrence (HR 1.24, 95% CI 1.12-1.38; p <0.0001, I2=3%). Sensitivity analyses evaluating only patients who underwent neoadjuvant chemotherapy followed by radical cystectomy showed an advantage of non/never smokers in terms of neoadjuvant chemotherapy complete response rate (HR 0.47, 95% CI 0.29-0.75; p=0.001, I2=0%). CONCLUSIONS: Smoking status is associated with lower neoadjuvant chemotherapy response rates and higher overall and cancer specific mortality as well as bladder cancer recurrence after radical cystectomy. Appropriate preoperative counseling, together with tightened followup, may have a pivotal role in improving the smoking-related long-term survival outcomes in patients with bladder cancer.

INTRODUCTION AND HYPOTHESIS: The objective was to describe a technique for the robotic repair of complex vesicovaginal fistula (VVF) with uterine preservation. METHODS: From 2015 to 2017, two patients underwent the procedure. Following placement of the patient in the lithotomy position, catheterization of the fistulous tract and laparoscopic omental harvesting is performed. Then, the robotic system is docked. A transverse incision was made in the peritoneum above the uterus was made to provide access to the bladder, the uterus is mobilized, and a cystotomy is performed to identify the structures. Subsequently, the cystotomy is extended toward the fistulous tract, the plane between the organs is dissected to proceed with the vaginal closure, the vagina is closed, the omental flap is interposed, and the bladder is closed. RESULTS: Mean operative time (OT) was 219 min. Mean estimated blood loss (EBL) was 75 ml. One of the patients had an intraoperative cervix canal injury that was identified and repaired. The postoperative course was uneventful, and the mean length of hospital stay (LOS) was 1 day. A mean follow-up of 17 (±9.89) months showed no recurrence at cystoscopy or imaging evaluation. CONCLUSIONS: Uterine-sparing VVF repair is feasible and safe. More studies are needed to assess equivalence compared with other procedures.

PURPOSE: The COVID-19 outbreak has substantially altered residents' training activities. While several new virtual learning programs have been recently implemented, the perspective of urology trainees regarding their usefulness still needs to be investigated. METHODS: A cross-sectional, 30-item, web-based Survey was conducted through Twitter from April 4th, 2020 to April 18th, 2020, aiming to evaluate the urology residents' perspective on smart learning (SL) modalities (pre-recorded videos, webinars, podcasts, and social media [SoMe]), and contents (frontal lessons, clinical case discussions, updates on Guidelines and on clinical trials, surgical videos, Journal Clubs, and seminars on leadership and non-technical skills). RESULTS: Overall, 501 urology residents from 58 countries completed the survey. Of these, 78.4, 78.2, 56.9 and 51.9% of them considered pre-recorded videos, interactive webinars, podcasts and SoMe highly useful modalities of smart learning, respectively. The contents considered as highly useful by the greatest proportion of residents were updates on guidelines (84.8%) and surgical videos (81.0%). In addition, 58.9 and 56.5% of responders deemed seminars on leadership and on non-technical skills highly useful smart learning contents. The three preferred combinations of smart learning modality and content were: pre-recorded surgical videos, interactive webinars on clinical cases, and pre-recorded videos on guidelines. CONCLUSION: Our study provides the first global «big picture¼ of the smart learning modalities and contents that should be prioritized to optimize virtual Urology education. While this survey was conducted during the COVID-19 outbreak, our findings might have even more impact in the future.

The aim of the present systematic review is to evaluate the impact of gender reassignment surgery on the development of urethral complication. A systematic search in accordance the Preferred Reporting Items for Systematic Review and Meta-Analyses statement for original articles published up until June 2019 was performed using the Pubmed, Scopus, Embase, and Web of Science databases. Pooled analyses were done when appropriate. The bibliographic search with the included terms (("Transsexualism"[Mesh])) AND ("Sex Reassignment Surgery"[Mesh]) produced a literature of 879 articles altogether. After removing papers of not interest or articles in which the outcomes could not be deduced, 32 studies were examined for a total of 3463 patients screened. Thirty-two studies met our inclusion criteria and were evaluated, and references were manually reviewed in order to include additional relevant studies in this review. Female-to-male (FtM) surgery and male-to-female (MtF) surgery was discussed in 23 and 10 studies, respectively. One study discussed both. Varying patterns of complications were observed in FtM and MtF surgeries, with increased complications in the former because of the larger size of the neourethra. Meatal stenosis is a particular concern in MtF surgery, with complication rates ranging from 4 to 40%, and usually require meatotomy for repair. Stricture and fistulization are frequently reported complications following FtM surgery. In studies reporting on fistulae involving the urethra, 19-54% of fistulae resolved spontaneously without further surgical intervention. High rates of complications are reported in the current literature, which should be understood by patients and practitioners alike. Shared decision making with patients regarding incidence and management of urethral complications including stricture disease and fistulae, particularly after FtM surgery, is critical for setting expectations and managing postoperative outcomes.

The case is of a 59-year-old male with history of severe ischemic colitis following emergent intervention for a ruptured infrarenal aortic aneurysm who subsequently underwent left hemicolectomy, partial proctectomy, and Hartmann colostomy. The patient later underwent reversal of the Hartmann colostomy with diverting ileostomy. The surgery was complicated by a right ureteral and posterior bladder injury that resulted in a large rectovesical fistula involving the right hemitrigone and right ureteral orifice. An attempt to repair the rectovesical fistula at an outside facility was unsuccessful. Then, he underwent a robotic-assisted laparoscopic repair of rectovesical fistula, including simple prostatectomy, excision of rectovesical fistulous tract, rectal closure, peritoneal and omental flap interposition, bladder neck reconstruction, vesicourethral anastomosis and right ureteral reimplantation. There were no intraoperative or postoperative complications, and the patient was discharged at postoperative day 4; cystoscopy at 6-week follow-up demonstrated a successful closure of the fistula, at which time the ureteral stents were removed.

A precise understanding of the autonomic innervation of the urinary tract is crucial to successful management of urologic disease given the important role that neurophysiology plays in genitourinary pathology. Recent studies using a combination of contemporary histopathology and imaging technologies have furthered our understanding of the spatial nerve distribution in the kidneys, ureters, and bladder. The findings of these recent studies may have important clinical applications in expanding our knowledge of the etiology and treatment of disease processes affecting the urinary tract. In this narrative review, our goal is to provide an overview of the autonomic innervation of the urinary tract. Specifically, we aim to provide a three-dimensional gender-specific description of renal, ureteral and vesical innervation. We also highlight some possible opportunities for clinical and investigational application of this new knowledge.
