Urological Manifestations of Isolated Iliac Artery Aneurysms

Abstract

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.

Acute Renal Failure in a Patient with Bilateral Aneurysms of Iliac Common Arteries

“…Ureteral obstruction by bilateral aneurysms of iliac common arteries is not a frequent event (1)(2)(3)(4)(5). We report this case for the following reasons:…”

A large unruptured isolated iliac artery aneurysm: rare presentation

“…Usually they remain asymptomatic until ruptured (incidence 33 to 77%). They may present with unique signs due to local compression of adjacent pelvic structure like Ureteral obstruction, Hematuria, Iliac vein thrombosis, Intestinal obstruction, Lower abdominal, flank, and groin pain, Lower extremity neurological deficit [5,6]. Large aneurysms can be palpated per abdominally or per rectally.…”

Massive hematuria after cystoscopy in a patient with an internal iliac artery aneurysm

“…Patients may have urological symptoms such as hematuria, bladder outlet obstruction or flank pain. 2,3 To our knowledge, 10 cases of fistula between an internal iliac artery aneurysm and the ureter or bladder have been reported. 4,5 Perioperative death occurs in 20-50% of patients with a ruptured internal iliac artery aneurysm.…”
