title: [Report of 2 cases of arterio-ureteral fistula].
abstract: Uretero-arterial fistulas are exceptional complications: only about forty cases have been reported in the literature. The authors report new two cases of fistula between the common iliac artery and the ureter. One fistula occurred in a context of prolonged ureteric stenting after radiotherapy and pelvic surgery for cancer of the uterus, and the other occurred after an aorto-bifemoral allograft. These fistulas generally occur in a particular clinical context, associating several aetiological factors. The clinical presentation is dominated by often massive and intermittent haematuria. The most useful diagnostic examinations are retrograde ureteropyelography and arteriography. The proposed treatment options (nephrectomy, vascular bypass graft and even embolization) depend on the urgency of the situation and involve both the blood vessel and the urinary tract. The prognosis depends on early diagnosis, but preventive measures can be envisaged to decrease the risk of appearance of these fistulas in high-risk patients.
