Show moreLong-term oncologic data on patients undergoing robot-assisted radical cystectomy (RARC) for non-metastatic bladder cancer (BCa) are limited. The purpose of this study is to describe long-term oncologic outcomes of patients receiving robotic radical cystectomy at a high-volume European Institution. We analyzed data of 107 patients treated with RARC between 2003 and 2012 at a high-volume robotic center. Clinical, pathologic, and survival data at the latest follow-up were collected. Clinical recurrence (CR)-free survival, cancer-specific mortality (CSM)-free survival, and overall survival (OS) were plotted using Kaplan-Meier survival curves. Cox proportional hazard models investigated predictors of CR and CSM. Competing-risk regressions were utilized to depict cumulative incidences of death from BCa and death from other causes after RARC at long term. Pathologic nonorgan-confined BCa was found in 40% of patients, and 7 (7%) patients had positive soft tissue surgical margins. Median (interquartile range [IQR]) number of nodes removed was 11 (6, 14), and 26% of patients had pN + disease. Median (IQR) follow-up for survivors was 123 (117, 149) months. The 12-year CR-free, CSM-free and overall survival were 55% (95% confidence interval [CI] 44%, 65%), 62% (95% CI 50%, 72%), and 34% (95% CI 24%, 44%), respectively. Nodal involvement on final pathology was associated with poor prognosis on multivariable competing risk analysis. The cumulative incidence of non-cancer death exceeded that of death from BCa after approximately ten years after RARC. We provided relevant data on oncologic outcomes of RARC at a high-volume robotic center, with acceptable rates of clinical recurrence and cancer-specific survival at long-term. In patients treated with RARC, the cumulative incidence of death from causes other than BCa is non-negligible, and should be taken into consideration for post-operative follow-up. Show less

Show moreObjectives: Radical cystectomy (RC) represents the gold standard treatment for high-risk bladder cancer. Despite evidence suggesting that surgical experience correlates with perioperative and oncologic outcomes of robot-assisted RC (RARC), validated tools to assess its quality objectively are lacking. We aimed to evaluate the impact of RC-Pentafecta (absence of early major complications, absence of urinary diversion related sequelae at <= 12 months, absence of soft tissue surgical margins, >= 16 lymph nodes at final pathology and absence of clinical recurrence at <= 12 months) on oncological outcomes and the role of surgical experience on its achievement. Materials and methods: We retrospectively evaluated 366 patients undergoing RARC with intracorporeal urinary diversion in a single tertiary centre with a minimum of 1 year follow-up. Surgeries were performed using the DaVinci Xi system according to a previously described technique. Kaplan-Meier curves were used to investigate 5-years overall survival and cancer specific mortality-free survival (CSS) according to RC-Pentafecta achievement. Multivariable Cox's regressions were performed to evaluate the impact of RC-Pentafecta on overall mortality. Multivariable logistic regressions were performed to explore the effect of surgical experience on RC-pentafecta achievement. Locally weighted scatterplot smoother function was used to graphically explore this relationship. Results: Patients achieving RC-Pentafecta showed higher 5-year overall survival (71.8% vs. 59.6%, P < 0.001) and CSS (84% vs. 71%, P < 0.001) when compared with patients not achieving it. At multivariable Cox's regression, RC-Pentafecta achievement (HR 0.57, P = 0.03), positive surgical margins (HR 2.48, P = 0.002), pN+ (HR 2.23, P = 0.002), pT >= 3 (HR 1.71, P = 0.04) and current smoking status (HR 2.4, P = 0.006) were significant predictors of overall mortality. At multivariable logistic regression surgical experience (OR 1.2, P < 0.001), age (OR 0.93, P = 0.04), previous prostate surgery (OR 0.7, P = 0.02) and pT >= 3 (OR 0.8, P = 0.03) were independent predictors of RC-Pentafecta achievement. A linear relationship between surgical experience and RC-Pentafecta achievement, without reaching a plateau, was observed. Conclusions: RC-Pentafecta is a valuable tool to assess surgical quality of RARC and the experience of the center where the surgery is performed and may be used to identify "referral" centers for treatment of high-risk bladder cancer.

Show moreBackground: The feasibility and efficacy of robot-assisted radical prostatectomy (RARP) in locally advanced prostate cancer (PCa) patients with iT3 lesion at magnetic resonance imaging (MRI) are currently not explored.Objective: To describe our revised RARP technique (ie, superextended RARP [SE-RARP]) for PCa patients with posterior iT3a or iT3b at MRI.Design, setting, and participants: Data from 89 patients with posterior iT3a or T3b disease who underwent SE-RARP at a single high-volume centre between 2015 and 2018 were analysed. Surgical procedure: RARP was performed using a DaVinci Xi system. The surgical approach provided an inter- or extrafascial RARP where Denonvilliers' fascia and perirectal fat were dissected free and left on the posterior surface of the seminal vesicles.Measurements: Perioperative outcomes, and intra- and postoperative complications were assessed. Postoperative outcomes were assessed in patients with complete follow-up data (n = 78). Biochemical recurrence (BCR) was defined as two consecutive prostate-specific antigen values of >= 0.2 ng/ml. Urinary continence (UC) recovery was defined as the use of zero or one safety pad. Kaplan-Meier and multivariable Cox regression models were used.Results and limitations: The median operative time, blood loss, and length of stay were 204 min, 300 ml, and 5 d, respectively. The median bladder catheterisation time was 5 d. Overall, 28%, 28%, and 27% of patients had pathological grade group (GG) 4-5, pT3b, and positive surgical margins (PSMs), respectively. Three patients (3.4%) experienced intraoperative complications. Among patients with available follow-up data (n = 78), 14 (18%) experienced 30-d postoperative complications. The median follow-up was 19 mo. Overall, 11 patients received additional treatment. At 2 yr of follow-up, BCR-free and additional treatment-free survival were 55% and 66%, respectively. Pathological GG 4-5 (hazard ratio [HR] 3.2) and PSM (HR 5.8) were independent predictors of recurrence, as well as of additional treatment use (HR 5.6 for GG 4-5 and 5.2 for PSM). The 1-yr UC recovery was 84%.Conclusions: We presented our revised RARP technique applicable to patients with posterior iT3a or iT3b at preoperative MRI. This technique is associated with good morbidity and continence recovery rates, and might guarantee biochemical control of the disease and postpone the use of additional treatments in patients with low-grade and negative surgical margins.Patient summary: A revised robot-assisted radical prostatectomy technique applicable to prostate cancer patients with posterior iT3a or iT3b lesion at magnetic resonance imaging was described. This novel technique is feasible and safe in expert hands. (C) 2020 European Association of Urology. Published by Elsevier B.V. All rights reserved. Show less

Show moreObjective To describe step-by-step surgical techniques and report outcomes of the largest single-centre series of patients with distal ureteric disease exclusively treated with robot-assisted ureteric reimplantation with Boari flap (RABFUR) and psoas hitch (RAPHUR), with a minimum follow-up of 1 year and complete postoperative data.Patients and Methods A total of 37 patients with distal ureteric disease were treated between 2010 and 2018. Of these, 81% and 19% underwent RAPHUR and RABFUR, respectively. Intra-, peri- and postoperative outcomes were assessed. The 90-day postoperative complications were reported according to the standardised methodology proposed by the European Association of Urology Ad Hoc Panel. Functional outcomes (creatinine, estimated glomerular filtration rate [eGFR]) and postoperative symptoms (visual analogue pain scale) were assessed.Results The median operating time and blood loss were 180 min and 100 mL, respectively. There were no conversions to open surgery and no intraoperative transfusions. The median length of stay, bladder catheter indwelling time and stent removal were 4, 7 and 30 days, respectively. The median follow-up was 24 months. Overall, 10 patients (27%) had postoperative complications and of these, eight (22%) and two (5.4%) were Clavien-Dindo Grade I-II and III, respectively. At the last follow-up, the median postoperative creatinine level and eGFR were 0.9 mg/dL and 73.5 mL/min/1.73 m(2), respectively. At the last follow-up, five (13.5%) and three (8%) patients had Grade 1 hydronephrosis and mild urinary symptoms, respectively. The study limitations include its retrospective nature.Conclusion In the present study, we present our RABFUR and RAPHUR techniques. We confirm the feasibility and safety profile of both approaches in patients with distal ureteric disease relying on the largest single-centre series with >= 1 year of follow-up. Show less

Show moreObjective To develop and seek consensus from procedure experts on the metrics that best characterise a reference robot-assisted radical prostatectomy (RARP) and determine if the metrics distinguished between the objectively assessed RARP performance of experienced and novice urologists, as identifying objective performance metrics for surgical training in robotic surgery is imperative for patient safety.Materials and methods In Study 1, the metrics, i.e. 12 phases of the procedure, 81 steps, 245 errors and 110 critical errors for a reference RARP were developed and then presented to an international Delphi panel of 19 experienced urologists. In Study 2, 12 very experienced surgeons (VES) who had performed >500 RARPs and 12 novice urology surgeons performed a RARP, which was video recorded and assessed by two experienced urologists blinded as to subject and group. Percentage agreement between experienced urologists for the Delphi meeting and Mann-Whitney U- and Kruskal-Wallis tests were used for construct validation of the newly identified RARP metrics.Results At the Delphi panel, consensus was reached on the appropriateness of the metrics for a reference RARP. In Study 2, the results showed that the VES performed similar to 4% more procedure steps and made 72% fewer procedure errors than the novices (P = 0.027). Phases VIIa and VIIb (i.e. neurovascular bundle dissection) best discriminated between the VES and novices. Limitations: VES whose performance was in the bottom half of their group demonstrated considerable error variability and made five-times as many errors as the other half of the group (P = 0.006).Conclusions The international Delphi panel reached high-level consensus on the RARP metrics that reliably distinguished between the objectively scored procedure performance of VES and novices. Reliable and valid performance metrics of RARP are imperative for effective and quality assured surgical training. Show less
