Methods: From January 2011 to March 2019, a total of 100 bladder cancer patients were treated with totally intracorporeal RARC in our institution by a single surgeon. The overall oncological and functional outcomes were evaluated. Results: Among the 100 totally intracorporeal RARC cases, 32 patients received an ileal conduit while the other 68 patients received an orthotopic neobladder. The positive surgical margin rate was 1.0%. The mean lymph node yield for the standard and extended pelvic lymph node dissection (PLND) was 23.1 and 34.6, respectively. The 5-year overall survival and 3-year recurrence-free survival rates were 72.1% and 68.1%, respectively. The 1-year daytime continence rate was 70.6%, while the nighttime continence rate was 41.2%. The potency preservation rate was 72.7% (n =8/11) with or without PDE5-I at 1 year. Conclusion : Totally intracorporeal RARC results in comparable oncological and functional outcomes to historical open radical cystectomy data. Large prospective data is required to draw any definitive conclusions. keywords : cystectomy, robotics, urinary bladder neoplasms
