Technique of creation of a continent internal ileal reservoir (Kock pouch) for urinary diversion.

Kock and associates have made a major contribution to the urologic surgical armamentarium by developing a method to create a continent internal urinary reservoir out of ileum. This innovative procedure now offers patients requiring cystectomy for bladder cancer or cutaneous urinary diversion for any reason a real alternative to the standard ileal conduit, which requires wearing an external appliance. Operative technique, including some modifications developed by the authors, is presented.
