Bellevue pouch: ileocolonic continent urinary reservoir.

The technique for the Bellevue Pouch, another continent intestinal reservoir, is described. A large-capacity low-pressure reservoir is created from detubularized ascending colon, cecum, and terminal ileum. Continence is achieved by means of an intussuscepted segment of ileum and a modulating colonic pressure cuff wrapped around it. The operation has been performed on 19 patients, all of whom achieved satisfactory continence. Two patients were converted to free drainage systems at a later date. Average follow-up was twenty-five months.
