Complex Ureteral Reconstruction in Kidney Transplantation

Exp Clin Transplant. 2021 May;19(5):425-433. doi: 10.6002/ect.2020.0566. Epub 2021 Mar 31.

Abstract

Objectives: Despite advances in surgical techniques and organ preservation, transplant ureteric strictures remain a common complication in kidney transplantation. A variety of endourological and surgical techniques have been utilized; however, there is a lack of consensus on the optimal modality in dealing with these complex cases.

Materials and methods: We present challenging ureteral reconstruction cases after failed attempts at ureteral dilatation, failed conventional open repairs, and/or with bladder dysfunction.

Results: All renal allografts were salvaged by successful use of bladder Boari flap and intestinal segment interpositions/diversions.

Conclusions: Operative repair remains the most durable and successful approach, and minimally invasive options should be reserved for nonsurgical candidates, with consideration of a single attempt in patients with early, distal, short (<2 cm), nonischemic strictures.
