Management of Complete Ureteral Replacement: Experiences and Review of the Literature

Abstract

The common treatment for patients with extensive damage to the ureter is complete ureteral replacement, combining Boari flap-psoas bladder hitch and downward mobilization of the involved kidney, with complete ideal replacement of the ureter, renal autotransplantation, or elective nephrectomy. Three case reports serve to describe two options of reconstructive treatment for complete ureteral replacement. The operative techniques, their limits, their postoperative results, and the treatment alternatives are discussed with due regard to recent literature. In the case of ileal replacement we have used a very short ileal segment to reduce the absorption surface of the ileal mucosa. Reflux prevention of the ileal segment was performed by creating an invaginated distal ileum nipple which was additionally fixed at the Boari flap by a third stapler row (auto suture TASS) to prevent potential nipple-gliding.
