Abstract:Objective: To investigate the clinical feasibility of Robot-assisted radical cystectomy (RARC) with totally intracorporeal urinary diversion (ICUD) and to present oncologic and functional outcomes.Methods: From March 2012 to June 2012, RARC with ICUD was performed on 10 patients diagnosed preoperatively with the bladder urothelial carcinomas. All patients underwent ICUD following RARC (ileal conduit urinary diversion for 2 patients and orthotopic ileal neobladder for 8 patients).Results: All patients underwent the laparoscopic procedure as planned. The operative time was 365-667 min (mean 471 min) with blood loss of 170-1 200 mL (mean 409 mL), and the number of removed lymph nodes was 9-25 (mean 18). For 2 patients undergoing ileal conduit urinary diversion, the ileoureteral stents were removed at 1st month. And for 8 patients undergoing orthotopic ileal neobladder, the ileoureteral stents and the urethral catheter were removed one month after a cystogram with confirmed watertight healing. Hospital stay was 8-26 days (mean 12 days). During the follow up period of 18-20 months (mean 19 months), 2 patients had disease recurrence and 1 died of disease. The remaining patients had satisfactory urinary continence and normal renal functions.Conclusions: With initial surgery and short-term follow-up, RARC with totally intracorporeal urinary diversion is feasible. More extensive surgical experiences as well as longer-term and more randomized trials will be required to better assess the appropriateness and potential of this technique.
