Complex Ureteral Reconstruction in Kidney Transplantation
EXPERIMENTAL AND CLINICAL TRANSPLANTATION(2021)
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.
