The experiences of rectosigmoid pouch as a continent urinary diversion after radical cystectomy

Thirty-five patients receiving cystectomy underwent rectosigmoid pouch. The technique of ureteral submucous implantation was described. The follow-up results were analyzed. The relationship of postoperative voiding frequency and preoperative anal closure pressure was assessed. The day and night time continence rate is 97% (34/35). There were no hydronephrosis, no ureterocolonic stricture or reflux. The complications are not unique to rectosigmoid pouch and not high when compared with other forms of urinary diversion. When the preoperative anal closure pressure reaches nearly 100 cmH2O a postoperative outcome with good quality of life will be predicted. With the advantages of high continence rate and simplicity of performance the rectosigmoid pouch will become one of the alternative forms of continent urinary diversion. For obtaining the favorable results a patient with normal renal function, good hepatic function and anal closure pressure more than 50 cmH2O is required.
