Urological manifestations of isolated iliac artery aneurysms.

Three patients with iliac artery aneurysms were seen at our institution with the chief complaints owing to urological manifestations. Iliac artery aneurysms may present with a transrectally palpable mass, hematuria, bladder outlet obstruction, ureteral obstruction, retroperitoneal fibrosis or renal failure. Any such manifestations may bring the aneurysm to the attention of a urologist before diagnosis.
