A randomized controlled trial comparing post transurethral resection of bladder tumor recurrence at three months non continuous bladder irrigation vs continuous bladder irrigation for bladder tumors less than or equal to three centimeters in size and less than or equal to three in number A single center study.

Continuous bladder irrigation (CBI) is commonly used after transurethral resection of bladder tumours. CBI involves a continuous flow of saline into the bladder through a catheter to prevent blood clots from forming and obstructing the urinary tract. It also prevents re-implantation and reduces recurrence post transurethral resection of bladder tumours (TURBT). Continuous bladder irrigation has been proposed as a potential intervention to reduce the risk of recurrence, although existing evidence is inconclusive and based on non randomized retrospective studies. Our aim is to scrutinize the efficacy of omitting continuous bladder irrigation in relation to the risk of recurrence at 3 months in <3 cm in size, ≤3 in number tumors. Additionally, we will assess postoperative increases in adverse events and conduct a cost analysis.
