A Case of Bilateral Ureteral Stenosis and Hydronephrosis due to Bilateral Internal Iliac Artery Aneurysm

Abstract

To our knowledge, there are no previous reports of bilateral internal iliac artery aneurysms with bilateral hydronephrosis. We herein report the successful surgical treatment of bilateral hydronephrosis in a 65-year-old woman. The patient was referred to the urology department of our medical center. CT showed bilateral internal iliac artery aneurysms （right: 30 mm, left: 26 mm） and hydronephrosis,which was caused by ureteral compression by the aneurysms. First, bilateral ureteral stents were placed to improve hydronephrosis. Then we performed open abdominal aortic graft replacement with bilateral internal iliac aneurysmectomy. The patient had no perioperative complications, and the ureteral stents were removed after the patient was discharged from the hospital.
