title: [Mainz pouch with umbilical stoma].
abstract: Between March 1986 and May 1991 the Mainz pouch urinary diversion was performed in 23 patients with bladder cancer. In 12 of these 23 patients, stoma was constructed in the umbilicus. As the efferent stomal limb, the ileum was used in 10 cases and the appendix was used in 2 cases. The skin at the bottom of the umbilicus and the abdominal fascia under the umbilicus were excised round. The stomal limb was pulled through the fascial hole and the stomal margin was sutured to the skin. The cosmetic results of the umbilical stoma were satisfactory in these 12 patients. Pouch capacity ranged from 330 ml to 560 ml and good urinary continence without difficulty of self-catheterization was obtained in 11 patients. In 1 patient difficulty in catheterization occurred due to a pocket-formation in the stomal limb and the operative revision was performed. Stomal stenosis occurred in 1 patient. Acute renal failure followed by intestinal bleeding occurred in 1 patient who was cured with intensive care including hemodialysis. The results of our study show the superiority of the umbilical stoma in the Mainz pouch in regard to good cosmetic appearance, no need to use a Marlex collar, little bending of catheterization route and low incidence of complications such as parastomal hernia or nipple valve prolapse.
