RESUMO
OBJECTIVES: To assess the impact of the learning curve (LC) on perioperative and long-term functional outcomes of a consecutive single-centre series of robot-assisted radical cystectomy with Padua intracorporeal orthotopic neobladder. PATIENTS AND METHODS: Patients treated between 2013 and 2022 were included, with ≥1 year of follow-up. The entire cohort was divided in tertiles. Categorical and continuous variables were compared. Joinpoint regression analysis was used to identify significant changes over the decade in linear slope of the 1-year day- and night-time continence. Uni- and multivariable Cox regression analyses identified predictors of day- and night-time continence recovery. Day-time continence was defined as 'totally dry' (no pads), night-time continence as pad wetness ≤50 mL (one safety pad). RESULTS: Overall, 200 patients were included. The mean hospital stay (P = 0.002) and 30-day complications (P = 0.04) significantly reduced over time; the LC significantly impacted on Trifecta achievement (P < 0.001). The 1-year day- and night-time continence probabilities displayed a significant improving trend (day-time continence annual average percentage change [AAPC] 11.45%, P < 0.001; night-time continence AAPC 10.05%, P = 0.009). The LC was an independent predictor of day- (hazard ratio [HR] 1.008; P < 0.001) and night-time continence (HR 1.004; P = 0.03) over time. CONCLUSION: Patients at the beginning of the LC had significantly longer hospitalisations, more postoperative complications, and lower Trifecta rates. At the 10-year analyses, we observed a significant improving trend for both the 1-year day- and night-time continence probabilities, highlighting the crucial role of the LC. However, we are unable to assess the case volume needed to achieve a plateau in terms of day- and night-time continence rates.

PURPOSE: To report long-term oncologic and functional outcomes of a large consecutive single center series of Robot-assisted radical cystectomy (RARC)- intracorporeal (IC) Urinary Diversion (UD), identifying their predicting factors. METHODS: A single center Bladder cancer (BC) database was queried for "RARC" and "ICUD", including patients treated between January 2012 and September 2020. Kaplan-Meier curves were assessed disease-free (DFS), cancer-specific (CSS) and overall survival (OS) probability. Univariable (UV) and multivariable (MV) analysis were adopted to identify predictors of DFS, CSS and OS. Kaplan-Meier method evaluated day- and night-time continence recovery probabilities; UV and MV analysis were adopted to identify predictors of Day-time continence. RESULTS: Overall, 251 patients were included. Among them, 192 patients underwent intracorporeal ileal orthotopic neobladder (ION) (76.5%). Five-year DFS, CSS and OS rates were 66.5%, 65.4% and 61.5%; pT stage ≥ 3 and pathologic nodal involvement were identified as negative independent predictors of DFS (HR 2.39, p = 0.001, HR 4.64, p ≤ 0.001), CSS (HR 2.20, p = 0.01, HR 3.97, p < 0.001) and OS (HR 2.25, p = 0.005, HR 3.95, p < 0.001). In RARC-ION patients, Trifecta rate was 64.1%. One-year day- and night-time continence rates were 78.6% and 48.3%. Age (HR 0.98, p = 0.03), female gender (HR 0.57, p = 0.008) and complications Clavien grade ≥ 3 (HR 0.55, p = 0.03) were identified as independent predictors of day-time incontinence. CONCLUSIONS: Long-term oncologic outcomes and their predicting factors seem aligned to the largest historical open series and multi-institutional robotic series data. According to the identified predicting factors undermining a proper achievement of day-time continence, this represents an objective support, in order to properly advice specific sub-group of patients.

INTRODUCTION AND OBJECTIVES: To evaluate late complications in a large cohort of patients undergoing robot-assisted radical cystectomy (RARC) with totally intracorporeal urinary diversion (ICUD). MATERIALS AND METHODS: We prospectively enrolled patients who underwent RARC and ICUD between August 2012 and June 2019. We excluded patients with Ejection fraction < 36%, retinal vasculopathy, ventriculoperitoneal shunts, and those treated without curative intent. All complications and their onset date have been recorded, defined, and graded according to Clavien classification adapted for radical cystectomy. RESULTS: 210 patients were included, 76% of whom were men, with a mean age of 62 years. Urinary diversions used were Padua Ileal Bladder (PIB) in 80% of cases, and ileal conduit (IC) in 20% of patients (generally older and with more comorbidity). The mean follow-up was 30 ± 22 months. The stenosis rate of uretero-ileal anastomosis was 14%, while a reduction in eGFR (≥ 20%) was observed in about half of the cases. UTIs occurred in 37% of the patients, especially in the first 12 months. Only 2% of patients had bowel occlusion, whereas incisional hernia, lymphocele, and systemic events (metabolic acidosis and major cardiovascular events) occurred respectively in 20%, 10%, and 1% of cases. CONCLUSIONS: Our study evaluates first late complications in a cohort of patients who underwent RARC with ICUD. These data are encouraging and in line with findings from a historical series of open radical cystectomy (ORC). This study is a further step in supporting RARC as a safe and effective surgical option for the treatment of muscle-invasive bladder cancer (MIBC) in tertiary referral centers.

INTRODUCTION: Robot-assisted radical cystectomy (RARC) with intracorporeal neobladder formation is a complex surgical procedure. AIM: To describe the main stages of RARC and to analyze its short-term results. MATERIALS AND METHODS: RARC with ileocystoplasty was performed in 16 patients, most of whom were men (n=14). In 15 patients, the indication for surgery was bladder cancer (BCa), while one patient has radiation-induced sigmoid fistula with a formation of small, contracted bladder. During radical cystectomy (RC), the lower ureters were dissected, followed by posterior dissection of the bladder with mobilization from both sides to the pelvic fascia, clipping and transection of the vesical pedicles, and suturing of the dorsal venous complex with urethral dissection. After pelvic lymph node dissection, 40 cm of the ileum was resected, after that two distal segments of 15 cm were U-shaped, and a 1.5 cm incision was made in the lower part of the bowel, followed by a formation of the urethral anastomosis. Then bowel segments were detubularized, and continuous suture on the posterior and anterior walls of the neobladder was done. Ureters were implanted in the proximal tubular part of the resected colon according to the Nesbit technique. RESULTS: The mean operation time was 380 minutes. The blood loss ranged from 80 to 200 ml; however, blood transfusion was not performed. Complications during 30-days after RARC were observed in 7 (43.7%) patients, including 4 (25%) of class I-II according to Clavien - Dindo, and 3 (18.7%) of class III-IV. In patients with leakage at the uretero- intestinal anastomosis (n=2) and urethro-neobladder anastomosis (n=1), percutaneous drainage was performed, which allowed to resolve these complications. There were no cases of bowel obstruction. One patient with gastrointestinal bleeding required blood transfusion. The 90-day late complications occurred in 6 (37.5%) patients, including 2 cases of upper urinary tract infection. One patient died of acute myocardial infarction. CONCLUSION: RARC is a contemporary minimally invasive method for muscle-invasive BCa. Stepwise approach to RARC with intracorporeal neobladder formation may reduce the operation time and the rate of complications.

OBJECTIVES: To perform a cost analysis comparing the cost of robot-assisted radical cystectomy (RARC) with open RC (ORC) in a UK tertiary referral centre and to identify the key cost drivers. PATIENTS AND METHODS: Data on hospital length of stay (LOS), operative time (OT), transfusion rate, and volume and complication rate were obtained from a prospectively updated institutional database for patients undergoing RARC or ORC. A cost decision tree model was created. Sensitivity analysis was performed to find key drivers of overall cost and to find breakeven points with ORC. Monte Carlo analysis was performed to quantify the variability in the dataset. RESULTS: One RARC procedure costs £12 449.87, or £12 106.12 if the robot was donated via charitable funds. In comparison, one ORC procedure costs £10 474.54. RARC is 18.9% more expensive than ORC. The key cost drivers were OT, LOS, and the number of cases performed per annum. CONCLUSION: High ongoing equipment costs remain a large barrier to the cost of RARC falling. However, minimal improvements in patient quality of life would be required to offset this difference.

Among the many milestones in the last several decades in the management of muscle-invasive bladder cancer and high-risk nonmuscle-invasive bladder cancer including the extension of the standard lymph node dissection and the use of neoadjuvant chemotherapy, minimally invasive techniques have gained traction as an attractive option for radical cystectomy. Open radical cystectomy is plagued with high rates of perioperative and postoperative morbidity and mortality, and as robotic assistance has demonstrated benefits in other arenas of surgery and urology, the evolution of the approach to radical cystectomy has likewise incorporated robotic assistance. We thus sought to critically review the literature comparing open radical cystectomy with robotic-assisted radical cystectomy. Perioperative and oncologic outcomes as well as cost analyses and health-related quality of life were compared between the two approaches, and identified manuscripts were categorized according to level of evidence.

Robot-assisted radical cystectomy (RARC) has been adopted widely in many centres, owed largely to the success of robot-assisted laparoscopic prostatectomy (RALP). It aims to replicate the oncological outcomes of open radical cystectomy (ORC), while providing a shorter recovery period. Despite this, previous RCTs have failed to show a benefit for RARC over ORC. These trials have compared extracorporeal RARC (eRARC) with ORC, which requires a further incision to mobilise the bowel for urinary reconstruction with an open technique. For intracorporeal RARC (iRARC), this urinary reconstruction is performed robotically without further incisions. There are theoretical benefits to this approach such as reduced recovery time for the bowel and reduced ileus rates, but no level 1 evidence currently exists to support this. While there has been an improvement in patient outcomes since the adoption of RARC, various other factors, such as enhanced recovery programmes and surgical learning curve, have made it difficult to attribute this solely to the robotic approach as many centres performing ORC have also shown similar improvements. In this review, we will discuss implementation of RARC as well as perioperative measures that have helped improve outcomes, offer a comparison of outcomes between ORC and RARC and highlight upcoming RCTs that may offer new evidence for or against a paradigm shift in the future of bladder cancer surgery.

Robot-assisted surgery has become a widely used surgical approach in the management of urologic malignancies. With its initial experience in the treatment of prostate cancer, the technology rapidly expanded to other urologic malignancies including bladder cancer. Since its introduction in 2003, robot-assisted radical cystectomy has seen refinement and increased penetration over the last decade. Furthermore, urologic surgeons have expanded its use to perform urinary diversions. The concept of intracorporeal urinary diversion is still in development but continues to see increased refinement among high volume academic centers.

To investigate the current status and feasibility of robotic neobladder diversion after robotic assisted radical cystectomy. A Medline search was conducted resulting in identification of 423 articles. After exclusion of ineligible studies, 3 case series and 5 case reports were considered with a total number of reported cases of 203. Although robotic intracorporeal neobladder reconstruction is in its starting phase, initial perioperative results seem to be comparable to open series. However, randomized studies are needed to confirm non-inferiority.

OBJECTIVE: To evaluate the effect of the learning curve on operative, postoperative, and pathological outcomes of the first 67 totally intracorporeal robot-assisted radical cystectomies (RARCs) with neobladders performed by two lead surgeons at Karolinska University Hospital. PATIENTS AND METHODS: Between December 2003 and October 2012, 67 patients (61 men and six women) underwent RARC with orthotopic urinary diversion by two main surgeons. Data were collected prospectively on patient demographics, peri- and postoperative outcomes including operation times, conversion rates, blood loss, complication rates, pathological data and length of stay (LOS) for these 67 consecutive patients. The two surgeons operated on 47 and 20 patients, respectively. The patients were divided into sequential groups of 10 in each individual surgeon's series and assessed for effect of the learning curve. RESULTS: Patient demographics and clinical characteristics were similar in both surgeons' groups. The overall total operation times trended down in both surgeons' series from a median time of 565 min in the first group of 10 cases, to a median of 345 min in the last group for surgeon A (P < 0.001) and 413 to 385 min for surgeon B (not statistically significant). Risk of conversion to open surgery also decreased with a 30% conversion rate in the first group to zero in latter groups (P < 0.01). Overall complications decreased as the learning curve progressed from 70% in the first group to 30% in the later groups (P < 0.05), although major complications were not statistically different when compared between the groups. Patient demographics did not change over time. The mean estimated blood loss was unchanged across groups with increasing experience. The pathological staging, mean total lymph node yield and number of positive margins were also unchanged across groups. There was a decrease in LOS from a mean of 19 days in the first group to a mean (range) of 9 (4-78) days in the later groups, although the median LOS was unchanged and therefore not statistically significant. CONCLUSIONS: Totally intracorporeal RARC with intracorporeal neobladder is a complex procedure, but it can be performed safely, with a structured approach, at a high-volume established robotic surgery centre without compromising perioperative and pathological outcomes during the learning curve for surgeons. An experienced robotic team and mentor can impact the learning curve of a new surgeon in the same centre resulting in decreased operation times early in their personal series, reducing conversion rates and complication rates.

Robot-assisted radical cystectomy (RARC) is an emerging operative alternative to open surgery for the management of invasive bladder cancer. Studies from single institutions provide limited data due to the small number of patients. In order to better understand the related outcomes, a world-wide consortium was established in 2006 of patients undergoing RARC, called the International Robotic Cystectomy Consortium (IRCC). Thus far, the IRCC has reported its findings on various areas of operative interest and continues to expand its capacity to include other operative modalities and transform it into the International Radical Cystectomy Consortium. This article summarizes the findings of the IRCC and highlights the future direction of the consortium.
RESUMO
INTRODUCTION: The aim of this report is to describe our surgical technique of totally intracorporeal robotic assisted radical cystectomy (RARC) with neobladder formation. MATERIALS AND METHODS: Between December 2003 and March 2013, a total of 147 patients (118 male, 29 female) underwent totally intracorporeal RARC for urinary bladder cancer. We also performed a systematic search of Medline, Embase and PubMed databases using the terms RARC, robotic cystectomy, robot-assisted, totally intracorporeal RARC, intracorporeal neobladder, intracorporeal urinary diversion, oncological outcomes, functional outcomes, and complication rates. RESULTS: The mean age of our patients was 64 years (range 37-87). On surgical pathology 47% had pT1 or less disease, 27% had pT2, 16% had pT3 and 10% had pT4. The mean number of lymph nodes removed was 21 (range 0-60). 24% of patients had lymph node positive dAQ1isease. Positive surgical margins occurred in 6 cases (4%). Mean follow-up was 31 months (range 4-115 months). Two patients (1.4%) died within 90 days of their operation. Using Kaplan-Meier analysis, overall survival and cancer specific survival at 60 months was 68% and 69.6%, respectively. 80 patients (54%) received a continent diversion with totally intracorporeal neobladder formation. In the neobladder subgroup median total operating time was 420 minutes (range 265-760). Daytime continence and satisfactory sexual function or potency at 12 months ranged between 70-90% in both men and women. CONCLUSIONS: Our experience with totally intracorporeal RARC demonstrates acceptable oncological and functional outcomes that suggest this is a viable alternative to open radical cystectomy.
RESUMO
Introduction: Surgical site infection (SSI) is a substantial cause of peri-operative morbidity among patients undergoing radical cystectomy (RC). The purpose of this study was to identify the risk factors of SSI after RC and to classify and characterize treatment of SSIs. Methods: We retrospectively analyzed peri-operative characteristics and SSI, for patients undergoing RC from 2007 to 2022. Patients were stratified by SSI versus no SSI and differences were assessed. Uni-variable/multi-variable logistic regression analyses were performed to identify factors associated with SSI. SSIs were categorized by the Centers for Disease Control and Prevention (CDC) type: Superficial incisional, deep incisional, and organ/space confined. Results: Three hundred and ninety-eight patients had RC, 279 open, and 119 robotic; 78 (19.6%) developed SSI. Cohorts were similar demographically. Length of stay (LOS) was longer in the SSI cohort (8.8 d versus 12.4 d, p < 0.001), and body mass index (BMI) was greater in patients with SSI (24.34 vs. 25.39, p = 0.0003). On uni-variable analysis, age, gender, Charlson Comorbidity Index, diabetes mellitus, diversion, odds ratio (OR) time, blood loss, and open versus robotic technique were not substantial SSI predictors. BMI was an independent risk factor for SSI on both uni-variable (OR: 1.07, 95% confidence interval [CI]: 1.018-1.115, p = 0.0061) and multi-variable analysis (OR: 1.06, 95% CI: 1.009-1.109, p = 0.02) for 10 (12.8%) and 24 (30.8%) superficial and deep-incisional SSIs, respectively. Superficial wound SSI was treated conservatively with 60% receiving antibiotic agents and no procedural intervention. Deep SSIs received antibiotic agents and 50% required surgical intervention. There were 44 (56.4%) organ/space SSIs, and the most common treatment was antibiotic agents (100%) and IR drain placement (30, 68.2%). Conclusion: In patients undergoing RC, BMI was an independent risk factor for SSI. Type of the surgical procedure, robotic versus open, was not predictive of SSI. LOS was longer for patients with SSI. SSI was managed differently depending on CDC classification.
RESUMO
Cystectomy is the gold standard treatment for muscle invasive bladder cancer. Robotic cystectomy has become increasingly popular owing to quicker post- operative recovery, less blood loss and less post-operative pain. Urinary diversion is increasingly being performed with an intracorporeal technique. Uretero-enteric strictures (UES) cause significant morbidity for patients. UES for open cystectomy is 3-10%, but the range is much wider (0-25%) for robotic surgery. We aim to perform systematic review for studies comparing all 3 techniques, to assess for ureteric stricture rates. A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement (Page et al. in BMJ 29, 2021). PubMed, Scopus and Embase databases were searched for the period January 2003 to June 2023 inclusive for relevant publications.The primary outcome was to identify ureteric stricture rates for studies comparing open cystectomy and urinary diversion, robotic cystectomy with extracorporeal urinary diversion (ECUD) and robotic cystectomy with intracorporeal urinary diversion (ICUD). Three studies were identified and included 2185 patients in total. The open operation had the lowest stricture rate (9.6%), compared to ECUD (12.4%) and ICUD (15%). ICUD had the longest time to stricture (7.55 months), ECUD (4.85 months) and the open operation (4.75 months). Open operation had the shortest operating time. The Bricker anastomoses was the most popular technique. Open surgery has the lowest rates of UES compared to both robotic operations. There is a learning curve involved with performing robotic cystectomy and urinary diversion, this may need to be considered to decide whether the technique is comparable with open cystectomy UES rates. Further research, including Randomised Control Trials (RCT), needs to be undertaken to determine the best surgical option for patients to minimise risks of UES.

Introduction and Objective: Scant literature is available on surgical outcomes of radical cystectomies on the new single-port (SP) system. This study compares short-term outcomes in patients undergoing radical cystectomy with those undergoing intracorporeal urinary diversion (ICUD) on the multiport (MP) vs SP platform. Methods: This institutional review board approved study used a prospective cystectomy database and nonparametric testing including chi-squared, Mann-Whitney U, and Fisher exact tests to analyze all variables stratified by surgical approach. Results: Thirty-four patients underwent radical cystectomy with ICUD from September 1, 2019, to February 8, 2021. Twenty patients were in the MP cohort, whereas 14 were in the SP group. Table 1 presents the demographics of both groups and shows no statistically significant differences. Intra- and postoperative as well as pathology data are given in Table 2. Patients in the SP group had less narcotic use (MP: 25 morphine milligram equivalent [MME] vs SP: 11.5 MME, p = 0.047) and shorter return of bowel function (MP: 3 days vs SP: 2 days, p = 0.032). Operative times were similar between both groups despite having fewer patients undergoing ileal conduit (MP: 85% vs SP: 50%, p = 0.027) in the SP group. In Table 3, we list the early short-term postoperative follow-up data for each group that showed no significant differences between the two groups with an average follow-up of 4.9 months for MP and 4.4 months for SP. Conclusions: Our initial experience with SP robotic cystectomy and ICUD appears to be safe and an effective alternative to MP cystectomies. A learning curve was involved but the overall transition from MP to SP was smooth. Operative times were similar despite fewer patients undergoing ileal diversion, shorter return of bowel function, and less narcotic use in the SP group. Further studies including longer follow-ups with multi-institutional data are underway.

We present operative, postoperative, oncologic and functional outcomes of genital tract sparing robot-assisted laparoscopic radical cystectomy, bilateral extended pelvic lymph node (LN) dissection and intracorporeal Studer pouch construction on five female patients with bladder cancer. One of the cases had concomitant nephroureterectomy performed due to a non-functioning kidney. Median patient age, mean operation time, median estimated blood loss and mean duration of hospital stay were 59 (39-78), 462 ± 25, 400 (50-970), 8.8 ± 2.5, respectively. Pathologic stages were pTis (n=1), pT1 (n=1), pT3 (n=1), pT4a (n=1) and pT4b (n=1). Mean LN yield was 32.4 ± 8.9. Positive surgical margins were detected in 2 patients with pT4 diseases. Only minor complications developed that were resolved with medical treatment. Two patients had no, 1 patient had mild, and 2 patients had moderate daytime incontinence. One patient had good, 3 patients had fair, and 1 had poor night-time incontinence. This complex robotic surgery can be performed safely with acceptable short-term surgical, oncological and functional outcomes.
RESUMO
The da Vinci single port surgical system (SP) is the newest iteration of robotic technology, which combines the camera and all instruments into a single port. Robotic assisted radical cystectomy (RARC) with intracorporeal urinary diversion has classically been a difficult operation. Here we describe our technique for RARC with the SP and review our initial outcomes and data in the literature. Four patients at our institution underwent single port robotic assisted radical cystectomy with intracorporeal ileal conduit using the da Vinci SP surgical system. Operative steps were performed as described. Perioperative outcomes were reviewed. All patients successfully underwent the procedure without intraoperative complications. The average operative time was 270 minutes with an EBL of 250 cc. The average nodal harvest was 12.5. The average length of stay was 5.5 days. There was one 30-day Clavien Grade II complication and no additional 90-day complications. With our initial experience with the da Vinci surgical system, radical cystectomy with intracorporeal urinary diversion can be performed safely and quickly with the right technique. Our outcomes are similar to other initially published data. Further study is necessary to determine the additional benefits and clinical outcomes.
RESUMO
INTRODUCTION: Radical cystectomy (RC) is a complex procedure with high perioperative morbidity. In an effort to reduce complications, robotic-assisted RC (RARC) has been adopted as a minimally invasive alternative to the open approach (ORC). Herein, we examine post-operative outcomes of the two surgical approaches in the United States (US) using a large all-payer database. MATERIAL AND METHODS: Using International Classification of Disease, ninth revision (ICD-9) codes, patient who underwent RC were captured from National Inpatient Sample (2008-2014). ICD-9 diagnosis and procedure codes were used to identify post-operative complications. Trends in the utilization of RARC were analyzed. Logistic and log-linear regression accounting for hospital sample weights and sampling years were performed to analyze outcomes after adjustment of pertinent covariates. RESULTS: Of 11,189 patients, 14% underwent RARC. RARC was performed in more teaching hospitals, male patients, those with private insurance, and lower comorbidity score. Performance of RARC steadily increased over the study period (p <0.01). In the last year of the study, 22.8% of cases performed robotically. The weighted average length-of-stay were 10.4 and 8.79 days for ORC and RARC, respectively (p <0.01). In multivariable analyses, RARC was associated with decreased blood transfusion, parenteral nutrition, pneumonia, surgical-site infection, wound and respiratory complications (all, p <0.05). No significant differences were found for in-hospital mortality, cardiac, genitourinary, and vascular complications. CONCLUSIONS: Performance of RARC has significantly increased in recent years. RARC appears safe and feasible for select patients. Earlier discharge and lower complications were noted for those undergoing RARC across different hospital systems nationwide.
RESUMO
BACKGROUND: The long-term oncological outcomes of laparoscopic (LRC) and robotic-assisted radical cystectomy (RARC) are still maturing compared with open radical cystectomy (ORC). OBJECTIVE: To evaluate the 5-yr oncological outcomes of patients recruited into the randomised trial of Open, Laparoscopic and Robot Assisted Cystectomy (CORAL) and extracorporeal urinary diversion. DESIGN, SETTING, AND PARTICIPANTS: A review of prospectively maintained database of 60 patients with muscle-invasive bladder cancer (MIBC) or high-risk nonmuscle-invasive bladder cancer (HRNMIBC) who were previously randomised in the CORAL trial to receive ORC, RARC, or LRC. This trial was designed to compare the perioperative and early oncological outcomes of these techniques. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The outcomes of interest included 5-yr recurrence-free survival (RFS), cancer-specific survival (CSS), and overall survival (OS). Kaplan-Meier curves were used to plot the recurrence and survival data. The curves between RFS, CSS, and OS were compared using the log-rank test. A two-sided p value <0.05 was considered significant. Results were analysed on the basis of intention to treat. RESULTS AND LIMITATIONS: A total of 60 patients with either MIBC (n=38) or HRNMIBC (n=21) were randomised in the CORAL trial to receive ORC, RARC, or LRC. The 5-yr RFS was 60%, 58%, and 71%; 5-yr CSS was 64%, 68%, and 69%; and 5-yr OS was 55%, 65%, and 61% for ORC, RARC, and LRC, respectively. There was no significant difference in RFS, CSS, and OS between the three surgical arms. The principal limitation is the small sample size. CONCLUSIONS: There was no difference in 5-yr RFS, CSS, and OS rates of patients who underwent ORC, RARC, and LRC for management of bladder cancer. Minimally invasive techniques achieved equivalent oncological outcomes to the gold standard of ORC. However, the study was based at a single institution with a small sample size. PATIENT SUMMARY: Patients who agreed to participate in the randomised trial of either open, laparoscopic, or robotic-assisted radical cystectomy for bladder cancer did not have different cancer outcomes at 5yr.
