A Case of Bilateral Ureteral Stenosis due to Inflammatory Common Iliac Artery Aneurysms / 日本心臓血管外科学会雑誌

ABSTRACT

A 71-year-old man was admitted complaining of abdominal pain. Contrast enhanced CT scan showed bilateral inflammatory common iliac artery aneurysms and encasement of bilateral ureters with perianeurysmal fibrosis. Drip infusion pyelography (DIP) showed bilateral hydronephrosis. After insertion of ureteral stents, Y-graft replacement and bilateral ureterolysis were performed successfully in spite of adhesion of the ureters to the aneurysmal wall. Postoperative DIP showed good passage in ureters and improvement of hydronephrosis. We would like to emphasize the usefulness of preoperative ureteral stenting for identification and mobilization of ureters.
