Ureteral obstruction of solitary kidneys by iliac artery aneurysms.
Two patients with solitary kidneys had ureteral obstruction caused by iliac artery aneurysms. Both patients were treated successfully with ureterolysis and temporary proximal diversion. Iliac artery aneurysms generally remain asymptomatic; however, patients may have urologic complaints (such as hematuria, flank pain, anuria, or a pulsatile urinary stream), and severe complications may develop as a result of an obstructive uropathy. Diagnosis is confirmed by cystoscopy when a mass is present, intravenous pyelography, retrograde pyelography, and arteriography. Treatment must be individualized with consideration of the etiology of the aneurysm and condition of the patient. Surgical correction of the aneurysm may be appropriate. Ureterolysis, with proximal diversion as a temporary safety valve, is a useful procedure particularly when the patient has a solitary kidney.
