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 utilisation of robot-assisted radical cystectomy with intracorporeal reconstruction (iRARC) has increased in recent years. Little is known about the length of the learning curve (LC) for this procedure. Objective: To study the length of the LC for iRARC in terms of 90-d major complications (MC90; Clavien-Dindo grade >= 3), 90-d overall complications (OC90, Clavien-Dindo grades 1-5), operating time (OT), estimated blood loss (EBL), and length of hospital stay (LOS). Design, setting, and participants: This was a retrospective analysis of all consecutive iRARC cases from nine European high-volume hospitals with >= 100 cases. All patients had bladder cancer for which iRARC was performed, with an ileal conduit or neobladder as the urinary diversion. Outcome measurements and statistical analysis: Outcome parameters used as a proxy for LC length were the number of consecutive cases needed to reach a plateau level in two-piece mixed-effects models for MC90, OC90, OT, EBL, and LOS. Results and limitations: A total of 2186 patients undergoing iRARC between 2003 and 2018were included. The plateau levels for MC90 and OC90 were reached after 137 cases (95% confidence interval [CI] 80-193) and 97 cases (95% CI 41-154), respectively. The mean MC90 rate at the plateau was 14% (95% CI 7-21%). The plateau level was reached after 75 cases (95% CI 65-86) for OT, 88 cases (95% CI 70-106) for EBL, and 198 cases (95% CI 130-266) for LOS. A major limitation of the study is the difference in the balance of urinary diversion types between centres. Conclusions: This multicentre retrospective analysis for the iRARC LC among nine European centres showed that 137 consecutive cases were needed to reach a stable MC90 rate. Patient summary: We carried out a multicentre analysis of the surgical learning curve for robot-assisted removal of the bladder and bladder reconstruction in patients with bladder cancer. We found that 137 consecutive cases were needed to reach a stable rate of serious complications. Show less

Show moreRobot-assisted radical cystectomy (RARC) continues to expand, and several surgeons start training for this complex procedure. This calls for the development of a structured training program, with the aim to improve patient safety during RARC learning curve. A modified Delphi consensus process was started to develop the curriculum structure. An online survey based on the available evidence was delivered to a panel of 28 experts in the field of RARC, selected according to surgical and research experience, and expertise in running training courses. Consensus was defined as >80% agreement between the responders. Overall, 96.4% experts completed the survey. The structure of the RARC curriculum was defined as follows: (1) theoretical training; (2) preclinical simulation-based training: 5-d simulation-based activity, using models with increasing complexity (ie, virtual reality, and dry-and wet-laboratory exercises), and nontechnical skills training session; (3) clinical training: modular console activity of at least 6 mo at the host center (a RARC case was divided into 11 steps and steps of similar complexity were grouped into five modules); and (4) final evaluation: blind review of a video-recorded RARC case. This structured training pathway will guide a starting surgeon from the first steps of RARC toward independent completion of a full procedure. Clinical implemen-tation is urgently needed. Patient summary: Robot-assisted radical cystectomy (RARC) is a complex procedure. The first structured training program for RARC was developed with the goal of aiding surgeons to overcome the learning curve of this procedure, improving patients' safety at the same time.

Show moreDevelopments within the field of image-guided surgery are ever expanding, driven by collective involvement of clinicians, researchers, and industry. While the general conception of the potential of image-guided surgery is to improve surgical outcome, the specific motives and goals that drive can differ between the different expert groups. To establish the current and future role of intra-operative image guidance within the field of image-guided surgery a Delphi consensus survey was conducted during the 2'd European Congress on Image-guided surgery. This multidisciplinary survey included questions on the conceptual potential and clinical value of image-guided surgery and was aimed at defining specific areas of research and development in the field in order to stimulate further advances towards precision surgery. Obtained results based on questionnaires filled in by 56 panel experts (clinicians: N=30, researchers: N=20 and industry: N=6) were discussed during a dedicated expert discussion session during the conference. The outcome of this Delphi consensus is indicative of the potential improvements offered by image-guided surgery and of the need for further research in this emerging-field, that can be enriched by the identification of reliable molecular targets.

Show moreBackground: There is a paucity of data describing the ability of margin, ischemia, complications, score (MIC) and trifecta in predicting long-term outcomes of robotic assisted partial nephrectomy (RAPN). Objective: To compare a novel trifecta (negative margins, no significant complications, and perioperative estimated glomerular filtration rate [eGFR] decrease <30%) versus standard MIC as predictors of oncologic and functional results in a large series of RAPNs. Design, setting, and participants: : Between 2009 and 2019, a multicenter dataset was queried for patients with nonmetastatic renal masses who underwent RAPN at eight participating institutions. Intervention: RAPN. Outcome measurements and statistical analysis: MIC and trifecta achievement were determined for the overall cohort and a subgroup undergoing off-clamp RAPN (ocRAPN), respectively. The overall survival (OS), recurrence-free survival (RFS), and new onset of end-stage renal disease (ESRD; defined as eGFR <30 ml/min) probabilities were assessed by the Kaplan-Meier method. Cox regression analyses were used to identify predictors of OS, RFS, and ESRD. For all analyses, two-sided p < 0.05 was considered significant. Results and limitations: Out of 1807 patients, MIC and trifecta were achieved in 71.1% (n = 1285) and 82.6% (n = 1492), respectively, and once restricted to the ocRAPN cohort, in 95.6% (n = 625) and 81.6% (n = 534), respectively. On Kaplan-Meier analysis, both MIC and trifecta achievement predicted higher OS and lower ESRD probabilities (all p < 0.014), while only trifecta achievement was a predictor of RFS probabilities (p = 0.009). On multivariable Cox regression, MIC did not predict any of the endpoints independently, while trifecta achievement was an independent predictor of higher OS (hazard ratio [HR] 0.4, 95% confidence interval [CI] 0.18-0.86; p = 0.019) and lower ESRD development probabilities (HR 0.32, 95% CI 0.15-0.72; p = 0.005). Conclusions: Trifecta, initially described as comprehensive measures of perioperative outcomes, needs to stand the test of time. Compared with MIC, the recent trifecta was an independent predictor of clinically significant endpoints, namely, survival and ESRD development probabilities. Patient summary: Our novel trifecta represents a reliable method for estimating survival and development of end-stage renal disease after robotic-assisted partial nephrectomy.

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 moreObjectives To evaluate the postoperative complication and mortality rate following laparoscopic radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD) in octogenarians.Patients and Methods We conducted a retrospective analysis comparing postoperative complication and mortality rates depending on age in a consecutive series of 1890 patients who underwent RARC with ICUD for bladder cancer between 2004 and 2018 in 10 European centres. Outcomes of patients aged <80 years and those aged >= 80 years were compared with regard to postoperative complications (Clavien-Dindo grading) and mortality rate. Cancer-specific mortality (CSM) and other-cause mortality (OCM) after surgery were calculated using the non-parametric Aalen-Johansen estimator.Results A total of 1726 patients aged <80 years and 164 aged >= 80 years were included in the analysis. The 30- and 90-day rate for high-grade (Clavien-Dindo grades III-V) complications were 15% and 21% for patients aged <80 years compared to 11% and 13% for patients aged >= 80 years (P = 0.2 and P = 0.03), respectively. In a multivariable logistic regression analysis adjusting for pre- and postoperative variables, age >= 80 years was not an independent predictor of high-grade complications (odds ratio 0.6, 95% confidence interval 0.3-1.1; P = 0.12). The non-cancer-related 90-day mortality was 2.3% for patients aged >= 80 years and 1.8% for those aged <80 years, respectively (P = 0.7). The estimated 12-month CSM and OCM rates for those aged <80 years were 8% and 3%, and for those aged >= 80 years, 15% and 8%, respectively (P = 0.009 and P < 0.001).Conclusions The minimally invasive approach to RARC with ICUD for bladder cancer in well-selected elderly patients (aged >= 80 years) achieved a tolerable high-grade complication rate; the 90-day postoperative mortality rate was driven by cancer progression and the non-cancer-related rate was equivalent to that of patients aged <80 years. However, an increased OCM rate in this elderly group after the first year should be taken into account. These results will support clinicians and patients when balancing cancer-related vs treatment-related risks and benefits. Show less

Show moreBackground: Evidence on the learning curve for robot-assisted radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD) is limited.Objective: To assess the effect of surgical experience (SE) on perioperative and intermediate-term oncological outcomes in a large contemporary cohort of RARC patients after accounting for the impact of intersurgeon variability.Design, setting, and participants: The study cohort included 164 patients treated with RARC and ICUD by two surgeons between 2004 and 2017 at a single European referral centre.Outcome measurements and statistical analysis: For each patient, SE was defined as the total number of RARCs performed by each surgeon before the patient's operation. The relationship between SE and operative time (OT), lymph node yield (LNY), positive surgical margins (PSMs), Clavien-Dindo grade >= 2 30-d postoperative complication (CD >= 2), and oncological outcomes (18-mo recurrence rate) was evaluated in multivariable linear and logistic regression models, clustering at a single-surgeon level.Results and limitations: After adjusting for case mix, SE was associated with shorter OT (p = 0.003), lower probability of postoperative CD >= 2 rates (p = 0.01), and lower 18-mo recurrence rates (p = 0.002). Conversely, SE did not predict lower PSM rates (p = 0.3) and higher LNY (p = 0.4). The relationship between SE and OT was nonlinear, with a plateau observed after 50 cases. Conversely, the relationship between SE and CD >= 2 and 18-mo recurrence was linear without reaching a plateau after 88 procedures.Conclusions: SE affects perioperative and oncological outcomes after RARC with ICUD in a linear fashion, and its beneficial effect does not reach a plateau. Conversely, after 50 cases, no further improvement was observed for OT.Patient summary: Robot-assisted radical cystectomy with intracorporeal urinary diversion is a complex surgical procedure with a relatively long learning curve.

Show moreAvailable comparison of transperitoneal robot-assisted partial nephrectomy (tRAPN) and retroperitoneal robot-assisted partial nephrectomy (rRAPN) does not consider tumour's location. The aim of this study was to compare perioperative morbidity, and functional and pathological outcomes after tRAPN and rRAPN, with the specific hypothesis that tRAPN for anterior tumours and rRAPN for posterior tumours might be a beneficial strategy. A large global collaborative dataset of 1169 cT1-2NOMO patients was used. Propensity score matching, and logistic and linear regression analyses tested the effect of tRAPN versus rRAPN on perioperative outcomes. No differences were observed between rRAPN and tRAPN with respect to complications, operative time, length of stay, ischaemia time, median 1-yr estimated glomerular filtration rate (eGFR), and positive surgical margins (all p > 0.05). Median estimated blood loss and postoperative eGFR were 50 versus100 ml (p < 0.0001) and 82 versus 78 ml/min/1.73 m(2) (p = 0.04) after rRAPN and tRAPN, respectively. At interaction tests, no advantage was observed after tRAPN for anterior tumours and rRAPN for posterior tumours with respect to complications, warm ischaemia time, postoperative eGFR, and positive surgical margins (all p > 0.05). The techniques of rRAPN and tRAPN offer equivalent perioperative morbidity, and functional and pathological outcomes, regardless of tumour's location.Patient summary: Robot-assisted partial nephrectomy can be performed with a transperitoneal or a retroperitoneal approach regardless of the specific position of the tumour, with equivalent outcomes for the patient.

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

Show morePurpose To assess the available literature evidence that discusses the effect of surgical experience on patient outcomes in robotic setting. This information is used to help understand how we can develop a learning process that allows surgeons to maximally accommodate patient safety. Methods A literature search of the MEDLINE/PubMed and Scopus database was performed. Original and review articles published in the English language were included after an interactive peer-review process of the panel. Results Robotic surgical procedures require high level of experience to guarantee patient safety. This means that, for some procedures, the learning process might be longer than originally expected. In this context, structured training programs that assist surgeons to improve outcomes during their learning processes were extensively discussed. We identified few structured robotic curricula and demonstrated that for some procedures, curriculum trained surgeons can achieve outcomes rates during their initial learning phases that are at least comparable to those of experienced surgeons from high-volume centres. Finally, the importance of non-technical skills on patient safety and of their inclusion in robotic training programs was also assessed. Conclusion To guarantee safe robotic surgery and to optimize patient outcomes during the learning process, standardized and validated training programs are instrumental. To date, only few structured validated curricula exist for standardized training and further efforts are needed in this direction. Show less

Show moreIntroduction The available studies comparing robot-assisted radical cystectomy (RARC) with intracorporeal (ICUD) vs. extracorporeal (ECUD) urinary diversion have not relied on a standardized methodology to report complications and did not assess the effect of different approaches on postoperative outcomes. Materials Two hundred and sixty seven patients treated with RARC at a single center were assessed. A retrospective analysis of data prospectively collected according to a standardized methodology was performed. Multivariable logistic regression models (MVA) assessed the impact of ICUD vs. ECUD on intraoperative complications, prolonged length of stay (LOS), 30-day Clavien Dindo (CD) >= 2 complications and readmission rate. Interaction terms tested the impact of the approach on different patient subgroups. Lowess graphically depicted the probability of CD >= 2 after ICUD or ECUD according to patient baseline characteristics. Results Overall, 162 ICUD vs 105 ECUD (61 vs. 39%) were performed. Intraoperative complications were recorded in 24 patients. The median LOS and readmission rate were 11 vs. 13 (p = 0.02) and 24 vs. 22% (p = 0.7) in ICUD vs. ECUD, respectively. Overall, 227 postoperative complications were recorded. The overall rate of CD >= 2 was 35 and 43% in patients with ICUD vs. ECUD, respectively (p = 0.2). At MVA, the approach type was not an independent predictor of any postoperative outcomes (all p >= 0.4). Age-adjusted Charlson Comorbidity Index (ACCI) was associated with an increased risk of CD >= 2 (OR: 1.2, p = 0.006). We identified a significant interaction term between ACCI and approach type (p = 0.04), where patients with ICUD had lower risk of CD >= 2 relative to those with ECUD with increasing ACCI. Conclusions Relying on a standardized methodology to report complications, we observed that highly comorbid patients who undergo ICUD have lower risk of postoperative complications relative to those patients who received ECUD.
