[Drainage-free ureterocutaneostomy].

Drainage-free cutaneous fistula of the ureter is suggested to assure permanent extravesical outlet of the urine in patients with incurable tumor-induced obstruction of the pelvic segment of the ureter. Fistulous orifice is formed with the aid of a triangular flap sitting on a pedicle; the flap is placed into a longitudinal incision in the stump of the drained ureter. Fifteen ureteral fistulas were formed in nine patients. Fourteen of them functioned reliably for several years without causing renal complications.
