Abstract

Retroperitoneal fibrosis sometimes causes urological problem involving the ureter, but the mechanism is uncertain. An aortic aneurysm, including an iliac artery aneurysm, is thought to be one of the mechanisms of retroperitoneal fibrosis. However, cases caused by an isolated iliac artery aneurysm are very rare, and symptoms tend to be non-specific; therefore, no definitive treatment has been established. Herein, we report our recent experience of a patient with a left common iliac artery aneurysm involving the ureter, who underwent successful surgical therapy.

  Fig. 2 (A) A pre-operative abdominal computed tomography (CT) scan, showing wide fibrosis around the left common iliac artery aneurysm (white arrow). (B) Post-operative abdominal CT scan, revealing notable regression of the aneurysm, with a double-J stent in the left ureter (black arrow) following an aneurysmectomy and ureterolysis with an omentum wrap.
