New Techniques of a Continence Mechanism for Mainz-Pouch Continent Cutaneous Urinary Diversion

Summary: In chronic animal studies, two new continence mechanisms (1. seromuscular-bowel-flap-tube, 2. full-thickness-bowel-flap-tube) fulfilled all requirements of a continence mechanism for continent cutaneous urinary diversion and were randomly used in Mainz-pouch-1 procedures (ileocecal pouch) in 30 patients, in whom the appendix was not available or usable for construction of a continent outlet and in 3 patients with other forms of continent cutaneous urinary diversion (1 transverse colon pouch, 1 conversion and 1 sigmoid colon pouch).
