Abstract Context Although open radical cystectomy (ORC) is still the standard approach, laparoscopic radical cystectomy (LRC) and robot-assisted radical cystectomy (RARC) have gained popularity. ...Objective To report a systematic literature review and cumulative analysis of perioperative outcomes and complications of RARC in comparison with ORC and LRC. Evidence acquisition Medline, Scopus, and Web of Science databases were searched using a free-text protocol including the terms robot-assisted radical cystectomy or da Vinci radical cystectomy or robot* radical cystectomy . RARC case series and studies comparing RARC with either ORC or LRC were collected. Cumulative analysis was conducted. Evidence synthesis The searches retrieved 105 papers. According to the different diversion type, overall mean operative time ranged from 360 to 420 min. Similarly, mean blood loss ranged from 260 to 480 ml. Mean in-hospital stay was about 9 d for all diversion types, with consistently high readmission rates. In series reporting on RARC with either extracorporeal or intracorporeal conduit diversion, overall 90-d complication rates were 59% (high-grade complication: 15%). In series reporting RARC with intracorporeal continent diversion, the overall 30-d complication rate was 45.7% (high-grade complication: 28%). Reported mortality rates were ≤3% for all diversion types. Comparing RARC and ORC, cumulative analyses demonstrated shorter operative time for ORC, whereas blood loss and in-hospital stay were better with RARC (all p values <0.003). Moreover, 90-d complication rates of any-grade and 90-d grade 3 complication rates were lower for RARC (all p values <0.04), whereas high-grade complication and mortality rates were similar. Conclusions RARC can be performed safely with acceptable perioperative outcome, although complications are common. Cumulative analyses demonstrated that operative time was shorter with ORC, whereas RARC may provide some advantages in terms of blood loss and transfusion rates and, more limitedly, for postoperative complication rates over ORC and LRC. Patient summary Although open radical cystectomy (RC) is still regarded as a standard treatment for muscle-invasive bladder cancer, laparoscopic and robot-assisted RC are becoming more popular. Robotic RC can be safely performed with acceptably low risk of blood loss, transfusion, and intraoperative complications; however, as for open RC, the risk of postoperative complications is high, including a substantial risk of major complication and reoperation.

Purpose Several case series have shown that reconstruction of the anterior or posterior periprostatic tissues facilitates early return of urinary continence after radical prostatectomy. We conducted ...a randomized clinical trial comparing early continence rates in patients undergoing urethrovesical anastomosis with or without periprostatic reconstruction. Materials and Methods A total of 116 consecutive patients undergoing computer assisted (robotic) prostatectomy performed by 1 of 2 experienced surgeons were randomized to single (without periprostatic reconstruction) or double layer (with periprostatic tissue reconstruction) urethrovesical anastomosis. Urinary loss was measured by pad weight at 1, 2, 7 and 30 days after catheter removal. Patients and data gatherers were blinded to treatment allocation. Results There were 57 patients randomized to the single and 59 to the double layer anastomosis group. All patients completed the study and followup. Using the conventional definition of urinary continence (0 to 1 pads daily) 26% and 34%, 49% and 46%, 51% and 54%, and 74% and 80% of patients undergoing single layer or double layer anastomoses were continent at 1, 2, 7 and 30 days, respectively (p >0.1). Of the patients in the 2 groups 7% and 15%, 14% and 14%, 16% and 20%, and 47% and 42% had no urinary leakage (0 gm or 0 pads daily) at these intervals, respectively (p >0.1). In each group 1 patient required prolonged catheterization because of cystographic evidence of anastomotic leakage. There were no other complications. Conclusions Early urinary continence rates were high in patients undergoing single or double layer urethrovesical anastomosis. We found no improvement in early continence rates with reconstruction of the periprostatic tissues.
This study aimed to provide an update and compare perioperative outcomes and complications of intracorporeal and extracorporeal urinary diversion following robot-assisted radical cystectomy using ...data from the multi-institutional, prospectively maintained International Robotic Cystectomy Consortium database.
We retrospectively reviewed the records of 2,125 patients from a total of 26 institutions. Intracorporeal urinary diversion was compared with extracorporeal urinary diversion. Multivariate logistic regression models using stepwise variable selection were fit to evaluate preoperative, operative and postoperative predictors of intracorporeal urinary diversion, operative time, high grade complications and 90-day hospital readmissions after robot-assisted radical cystectomy.
In our cohort 1,094 patients (51%) underwent intracorporeal urinary diversion. These patients demonstrated shorter operative time (357 vs 400 minutes), less blood loss (300 vs 350 ml) and fewer blood transfusions (4% vs 19%, all p <0.001). They experienced more high grade complications (13% vs 10%, p = 0.02). Intracorporeal urinary diversion use increased from 9% of all urinary diversions in 2005 to 97% in 2015. Complications after this procedure decreased significantly with time (p <0.001). On multivariable analysis higher annual cystectomy volume (OR 1.02, 95% CI 1.01–1.03, p <0.002), year of robot-assisted radical cystectomy (2013–2016 OR 68, 95% CI 44–105, p <0.001) and American Society of Anesthesiologists® score less than 3 (OR 1.75, 95% CI 1.38–2.22, p <0.001) were associated with undergoing intracorporeal urinary diversion. The procedure was associated with a shorter operative time of 27 minutes (p = 0.001).
The use of intracorporeal urinary diversion has increased in the last decade. A higher annual institutional volume of robot-assisted radical cystectomy was associated with intracorporeal urinary diversion as well as with shorter operative time. Although intracorporeal urinary diversion was associated with higher grade complications than extracorporeal urinary diversion, they decreased with time.
Using institutional data, we have previously developed an algorithm to identify the optimal candidates for adjuvant radiotherapy (aRT) among men with pN1 prostate cancer (PCa) at radical ...prostatectomy (RP). This study aimed to test the external validity of our previous findings using a nationwide database while focusing on overall mortality as an endpoint. To this end, we identified 5498 pN1 PCa patients who were treated with RP, pelvic lymph node dissection, and androgen deprivation therapy with or without aRT, within the National Cancer Database, between 2004 and 2015. Patients were divided into five groups based on our previously published algorithm. Similar to our previous report, multivariable Cox regression analysis showed that only two of these groups benefit from aRT: (1) those with one to two positive nodes, pathological Gleason score 7–10, and pT3b/4 disease or positive surgical margins (hazard ratio HR=0.75); and (2) those with three to four positive nodes, regardless of local tumor characteristics (HR=0.57, both p=0.01). In the remaining patients (25% of the cohort), aRT had no significant survival benefit. Results were confirmed on sensitivity analyses using 1:1 propensity score-matched cohorts, excluding men who died within 3 yr of surgery and using cut-off of 6 mo post-surgery to identify receipt of aRT. Our findings corroborate the validity of our previously published criteria and highlight the importance of patient selection in pN1 PCa patients who are considered for aRT.
When considering prostate cancer patients with node positive-disease at surgery for adjuvant radiotherapy, select patients wisely. Local disease characteristics and number of positive nodes play a key role in determining who will benefit from such a treatment.

Abstract Background Long-term oncologic data on patients undergoing robot-assisted radical cystectomy (RARC) are limited and based largely on single-institution series. Objective Report survival ...outcomes of patients who underwent RARC ≥5 yr ago. Design, setting, and participants Retrospective review of the prospectively populated International Robotic Cystectomy Consortium multi-institutional database identified 743 patients with RARC performed ≥5 yr ago. Clinical, pathologic, and survival data at the latest follow-up were collected. Patients with palliative RARC were excluded. Final analysis was performed on 702 patients from 11 institutions in 6 countries. Intervention RARC. Outcome measurements and statistical analysis Outcomes of interest, recurrence-free survival (RFS), cancer-specific survival (CSS), and overall survival (OS) were plotted using Kaplan-Meier survival curves. A Cox proportional hazards model was used to identify factors that predicted outcomes. Results and limitations Pathologic organ-confined (OC) disease was found in 62% of patients. Soft tissue surgical margins (SMs) were positive in 8%. Median lymph node (LN) yield was 16, and 21% of patients had positive LNs. Median follow-up was 67 mo (interquartile range: 18–84 mo). Five-year RFS, CSS, and OS were 67%, 75%, and 50%, respectively. Non-OC disease and SMs were associated with poorer RFS, CSS, and OS on multivariable analysis. Age predicted poorer CSS and OS. Adjuvant chemotherapy and positive SMs were predictors of RFS (hazard ratio: 3.20 and 2.16; p < 0.001 and p < 0.005, respectively). Stratified survival curves demonstrated poorer outcomes for positive SM, LN, and non-OC disease. Retrospective interrogation and lack of contemporaneous comparison groups that underwent open radical cystectomy were major limitations. Conclusions The largest multi-institutional series to date reported long-term survival outcomes after RARC. Patient summary Patients who underwent robot-assisted radical cystectomy for bladder cancer have acceptable long-term survival.

Objective To develop and establish effectiveness of simulation-based robotic curriculum - fundamental skills of robotic surgery (FSRS). Methods FSRS curriculum was developed and incorporated into a ...virtual reality simulator, Robotic Surgical Simulator (RoSS). Fifty-three participants were randomized into an experimental group (EG) or control group (CG). The EG was asked to complete the FSRS and 1 final test on the da Vinci Surgical System (dVSS). The dVSS test consisted of 3 tasks: ball placement, suture pass, and fourth arm manipulation. The CG was directly tested on the dVSS then offered the chance to complete the FSRS and re-tested on the dVSS as a crossover (CO) group. Results Sixty-five percent of participants had never formally trained using laparoscopic surgery. Ball placement: the EG demonstrated shorter time (142 vs 164 seconds, P = .134) and more precise (1.5 vs 2.5 drops, P = .014). The CO took less time ( P <.001) with greater precision ( P <.001). Instruments were rarely lost from the field. Suture pass: the EG demonstrated better camera utilization (4.3 vs 3.0, P = .078). Less instrument loss occurred (0.5 vs 1.1, P = .026). Proper camera usage significantly improved ( P = .009). Fourth arm manipulation: the EG took less time (132 vs 157 seconds, P = .302). Meanwhile, loss of instruments was less frequent (0.2 vs 0.8, P = .076). Precision in the CO improved significantly ( P = .042) and camera control and safe instrument manipulation showed improvement (1.5 vs 3.5, 0.2 vs 0.9, respectively). Conclusion FSRS curriculum is a valid, feasible, and structured curriculum that demonstrates its effectiveness by significant improvements in basic robotic surgery skills.

Objective
To compare the perioperative outcomes of intracorporeal (ICUD) vs extracorporeal urinary diversion (ECUD) after robot‐assisted radical cystectomy (RARC).
Patients and Methods
We ...retrospectively reviewed the prospectively maintained International Robotic Cystectomy Consortium (IRCC) database. A total of 972 patients from 28 institutions who underwent RARC were included. Propensity score matching was used to match patients based on age, gender, body mass index (BMI), American Society of Anesthesiologists Score (ASA) score, Charlson Comorbidity Index (CCI) score, prior radiation and abdominal surgery, receipt of neoadjuvant chemotherapy, and clinical staging. Matched cohorts were compared. Multivariate stepwise logistic and linear regression models were fit to evaluate variables associated with receiving ICUD, operating time, 90‐day high‐grade complications (Clavien–Dindo Classification Grade ≥III), and 90‐day readmissions after RARC.
Results
Utilisation of ICUD increased from 0% in 2005 to 95% in 2018. The ICUD patients had more overall complications (66% vs 58%, P = 0.01) and readmissions (27% vs 17%, P = 0.01), but not high‐grade complications (21% vs 24%, P = 0.22). A more recent RC era and ileal conduit diversion were associated with receiving an ICUD. Higher BMI, ASA score ≥3, and receiving a neobladder were associated with longer operating times. Shorter operating time was associated with male gender, older age, ICUD, and centres with a larger annual average RC volume. Longer intensive care unit stay was associated with 90‐day high‐grade complications. Higher CCI score, prior radiation therapy, neoadjuvant chemotherapy, and ICUD were associated with a higher risk of 90‐day readmissions.
Conclusions
Utilisation of ICUD has increased over the past decade. ICUD was associated with more overall complications and readmissions compared to ECUD, but not high‐grade complications.

Abstract Because surgical skill may be a key determinant of patient outcomes, there is growing interest in skill assessment. In the Michigan Urological Surgery Improvement Collaborative (MUSIC), we ...assessed whether peer and crowd-sourced (ie, layperson) video review of robot-assisted radical prostatectomy (RARP) could distinguish technical skill among practicing surgeons. A total of 76 video clips from 12 MUSIC surgeons consisted of one of four parts of RARP and underwent blinded review by MUSIC peer surgeons and prequalified crowd-sourced reviewers. Videos were rated for global skill (Global Evaluation Assessment of Robotic Skills) and procedure-specific skill (Robotic Anastomosis and Competency Evaluation). We fit linear mixed-effects models to estimate mean peer and crowd ratings for each video. Individual video ratings were aggregated to calculate surgeon skill scores. Peers ( n = 25) completed 351 video ratings over 15 d, whereas crowd-sourced reviewers ( n = 680) completed 2990 video ratings in 38 h. Surgeon global skill scores ranged from 15.8 to 21.7 (peer) and from 19.2 to 20.9 (crowd). Peer and crowd ratings demonstrated strong correlation for both global ( r = 0.78) and anastomosis ( r = 0.74) skills. The two groups consistently agreed on the rank order of lower scoring surgeons, suggesting a potential role for crowd-sourced methodology in the assessment of surgical performance. Lack of patient outcomes is a limitation and forms the basis of future study. Patient summary We demonstrated the large-scale feasibility of assessing the technical skill of robotic surgeons and found that online crowd-sourced reviewers agreed with experts on the rank order of surgeons with the lowest technical skill scores.

Abstract Background Reports on long-term oncologic outcomes for patients who undergo robot-assisted radical prostatectomy (RARP) are scant, as for radical prostatectomy covering only the contemporary ...prostate-specific antigen (PSA) era. Objective To evaluate cancer control in men who underwent RARP at least 10 yr ago. Design, setting, and participants From 2001 to 2003, we followed 483 consecutive men with localized prostate cancer who underwent RARP at a high-volume tertiary center. Intervention RARP as first-line therapy. Outcome measurements and statistical analysis We calculated biochemical recurrence –free survival (BCRFS), metastasis-free survival (MFS), and cancer-specific survival (CSS). Actuarial rates were estimated via Kaplan-Meier. Cox proportional hazards models were used to identify variables predictive of biochemical recurrence (BCR), receipt of salvage therapy, and metastases. Results and limitations There were 108 patients with BCR at a median follow-up of 121 mo (interquartile range: 97–132). Actuarial BCRFS, MFS, and CSS rates at 10 yr were 73.1%, 97.5%, and 98.8%, respectively. On multivariable analysis, D’Amico risk groups or pathologic Gleason grade, stage, and margins were the strongest predictors of BCR depending on whether preoperative or postoperative variables were considered. The value of the detectable PSAs together with disease severity were independent predictors of receipt of salvage therapy, together with a persistent PSA for metastases. Conclusions In contemporary patients with localized prostate cancer, RARP confers effective 10-yr cancer control. Disease severity and PSA measurements can be used to guide more personalized and cost-effective postoperative surveillance regimens. Patient summary Robot-assisted radical prostatectomy confers effective 10-yr cancer control for men with localized disease, similar to the open approach. Recurrence is best predicted by postoperative disease severity. Persistent disease signals the risk of progression likely requiring early salvage treatment; lower postoperative risk warrants protracted surveillance beyond 5 yr from surgery, and those with higher risk may require follow-up beyond 10 yr.
