Further experience with the modified rectal bladder (the augmented and valved rectum) for urine diversion.

Abstract

Continent diversion with the modified rectal bladder was done in 83 patients and 65 are currently evaluable with followup ranging from 6 to 36 months. There was no postoperative mortality and the morbidity rate was acceptable. Renal function and configuration were maintained in most patients (91%). Dessusception of the colorectal valve was observed in 7.6% of the patients. Evidence was provided that this valve is effective in prevention of regurgitation of the rectal contents to the proximal colon. All patients were continent during the day. Enuresis was noted in 6 patients and all of them responded to imipramine hydrochloride therapy. The results support earlier observations that the procedure offers distinct advantages over ureterosigmoidostomy and the simple rectal bladder.
