A simplified technique for continent urinary diversion: an all-stapled colonic reservoir.

Abstract

A simple continent colonic reservoir was constructed in its entirety with the aid of surgical stapling techniques in 17 men and 10 women. In 5 men an orthotopic pouch was created and in the rest a continent stoma was designed. Detubularization of the entire colonic segment assures a low pressure system with disruption of directional peristaltic activity. The ureters are implanted by simply burying them in a mucosal furrow. Operative time required for the creation of the reservoir (excluding time for cystectomy) has ranged between 70 and 140 minutes (mean 95.4 minutes). With a followup of 9 to 60 months (mean 22.8 months) continence has been achieved in all but 1 patient with no ureteral reflux or obstruction. Urodynamically the pouch has achieved a large capacity (mean 750 cc) with low filling pressures (8.1 cm. water) because of technical ease of construction together with a shortened operative time due to the stapling techniques. This form of bladder replacement offers an option for select patients in whom continent urinary diversion is contemplated.
