Role of the Kock pouch in adolescent urology.

Although cutaneous urinary diversion will continue to have a place in some urological diseases, some patients may benefit from an undiversion. The Kock pouch with a continent reservoir is an alternative where conventional undiversion to the bladder is impossible. Indications, pre-operative preparation, operative technique, results and complications are outlined in detail. In the adolescent patient requiring urinary diversion the Kock pouch should be considered as the last resort. Where reconstruction of the urinary tract is impossible, a continent urinary reservoir by means of the Kock pouch may be indicated.
