Continent Cutaneous Diversion.

Techniques in continent cutaneous urinary diversion (CCUD) have evolved significantly over the last 30 years resulting in several well-established procedures. CCUD is well suited for patients in whom the urethra cannot be used for orthotopic diversion due to preexisting incontinence, radiation damage, or malignancy. Reservoirs are constructed with adherence to basic principles of continent urinary diversion, including the use of detubularized bowel in a spherical conformation for pouch creation with either ileum or the right colon. The article reviews the history, patient selection, preoperative evaluation, surgical technique, and outcomes of CCUD.
