Oncological and functional outcome of robotic-assisted radical cystectomy with total intracorporeal stentless J-pouch neobladder reconstruction

BackgroundRobotic-assisted radical cystectomy (RARC) with neobladder reconstruction has gained popularity in recent years.MethodsWe conducted a retrospective study of 17 consecutive patients who underwent RARC with totally intracorporeal J-pouch neobladder reconstruction without ureteral stent by a single experienced surgeon to evaluate perioperative, oncological and functional outcomes.ResultsThe median follow-up duration was 32.8 months (range: 17.4-59.0 months), and the 2-year disease-free survival rate was 88.2%. Five out of 12 patients were totally continent, and none required more than one pad per day. The overall complication rate was 41.2%, and hydronephrosis was the most common adverse event. The renal function remained stable, and no long-term renal function impairment was detected.ConclusionOur study suggests that RARC with totally intracorporeal J-pouch neobladder reconstruction without ureteral stent is a safe and feasible option for the treatment of muscle-invasive bladder cancer, with good oncological and functional outcomes.
