Abstract
The modifid Kock continent internal reservoir procedure has ben performed on 15 patients at our medical center since December 1984: 13 underwent simultaneous anterior exenteration for pelvic malignancy, 1 had conversion from an ileal conduit and 1 underwent cystectomy for refractory interstitial cystitis. There was no operative mortality. There were 3 early complications: a urinary leak from the pouch in 2 patients that required re-exploration to close the defect, and an enteric-Kock pouch fistula in 1 that required resection of the small bowel fistula and repair of the pouch defect. All 3 patients ae doing well. The late complication in 3 cases was urinary incontinence of the efferent nipple valve with difficult in catheterization of the stoma. Two patients have undergone revision with a new efferent nipple valve added on to the pouch and creation of a new stoma. One patient is completely dry and continent, 1 has tolerable intermittent leakage and refuses a further operation, and 1 is awaiting revision. Although the initial experience is small, we are encouraged by these results and believe that this procedure is an alternative form of urinary diversion for the properly selected patient.
