The modified Indiana pouch.

The modified continent Indiana pouch is based upon the terminal 8-12 cm of ileum and 26-28 cm of right colon. Our modifications include complete detubularization of the colonic segment with an easier appendectomy, a transcolonic ureteral reimplantation that is technically simple, and reinforced plication of the ileocecal junction. This procedure was performed in 70 patients (ages 27-85 years) with follow-up ranging between 3-24 months. There have been five hospitalizations for urinary tract infections or gastrointestinal complications. Three open surgical revisions (4%) have been necessary: one for incontinence, one for a redundant ileal limb and difficult catheterization and one for ureteral stenosis in the mid-portion of the left ureter. One revision is pending for inadequate reservoir volume. Two endoscopic meatotomies of ureterocolonic junction strictures have been necessary. All patients are continent day and night, enjoy easy catheterization of volumes ranging between 400 and 800 cc. The modified Indiana pouch should be considered for any patient requiring cutaneous urinary diversion because of a low complication and revision rate and an excellent continence rate.
