title: [Bilateral obstruction of the ureters as a complication of iliac aneurysms].
abstract: A case of bilateral obstruction of the ureters secondary to iliac aneurysms is reported. While perianeurysmal fibrosis in so-called "inflammatory" aneurysms causes the obstruction in most cases, this is a report on a case of compression of both ureters by huge aneurysms without inflammatory reaction. Recurrent back pain of urinary type is the first symptom in 75% of the cases. Ultrasonography shows hydronephrosis and deviation of the ureters as well as the aneurysms. Intravenous pyelography, angiography and CT-scan are necessary to show the real size of the ureters and the aneurysm. Treatment of choice is resection of the aneurysm and replacement by a prosthesis. Ureterolysis may be necessary if the ureters are enveloped by perianeurysmal fibrosis.
