Abstract

Since continent urinary diversion and bladder substitution after cystoprostatectomy have been offered as alternative to standard urinary diversion, increasing numbers of patients seek to avoid a wet stoma. So since 1988 we have used a pouch constructed from a combination of large and small bowel(Mainz pouch), which offers a low pressure reservoir of adequate capacity, antirefluxing ureteral reimplantation and continent reservoir. Initial applications of the Mainz pouch were for bladder augmentation after subtotal cystectomy and for continent urinary diversion. Current indications have been extended to complete bladder substitution after radical cystectomy with anastomosis of the pouch to the membranous urethra. A total or 15 patients underwent a Mainz pouch procedure ;6 for bladder augmentation, 8 for continent urinary diversion and 1 for total bladder substitution after radical cystectomy. All bladder augmentation cases, 4 of 8 diversion cases and substitution case are completely dry day and night. There are no significant perioperative morbidity and mortality.
