Urinary undiversion. Montreal Children's Hospital experience

Nine patients underwent urinary tract refunctionalization after prior supravesical diversion. Emphasis is placed on careful preoperative evaluation of these patients, including studies of renal and bladder function. In 8 patients continuity could be restored without interposition of bowel segment, while in the ninth case, this was necessary because of short ureteral lengths bilaterally. This was the only technical failure in this series requiring restoration of the diverted state. There was a dramatic improvement noted in the quality of life and mental status in the 8 patients in whom the procedure was successful.
