Abstract

U-shaped Bilateral Ileal Ureter Substitution for Failed Conservative Management of Retroperitoneal Fibrosis: A Case Report

Mang L Chen, Adam W Ylitalo and Richard A Santucci

Introduction: Retroperitoneal fibrosis (RPF) can cause bilateral chronic obstruction of the ureters. Definitive surgical management includes ureterolysis with omental wrapping or ileal ureter substitution. We present a case of bilateral ureteral obstruction from RPF in a patient with a large abdominal aortic aneurysm (AAA) managed with bilateral ileal ureter substitution in the U-configuration.

Case presentation: A 65-year-old man had medically refractory RPF with bilateral ureteral obstruction that failed ureteral stenting. He required bilateral nephrostomy tubes. Initially bilateral ureterolysis was considered, but given his large AAA and the proximity of the ureters to the aneurysm, ileal substitution was recommended. We attempted a “7” shaped configuration at first, but the natural lie of the ileal segment led us to perform a “U”-shaped substitution with the ends sewn to both renal pelvises and the middle portion sewn to the bladder dome. Postoperatively, the patient recovered well, and at two months followup, the patient has a stable serum creatinine and no hydronephrosis. He no longer requires ureteral stenting or nephrostomy tube drainage.

Conclusion: Bilateral ileal ureter substitution is a viable option for patients with RPF induced hydronephrosis who fail conservative management. The U-shape is a novel configuration that may facilitate this procedure.
