RESUMEN
Although ureteroarterial fistulas are rare, they result in a high mortality because of the massive urogenital haemorrhage. The diagnosis is often difficult even when invasive measures are applied. Including the ureteroarterial fistula in the diagnostic process in cases of macrohaematuria with a positive medical history can be helpful. A ureteroarterial fistula typically develops in pa-tients who have undergone pelvic surgery and radiation as well as after long-term ureteral stents. Patients are usually multimorbid. The treatment of choice consists of fistula exclusion by stent graft deployment in the iliac artery and application of a ureteral stent or a ureterostomy. The significance of surgical treatment is diminishing. The long-term results of endovascular treatment, however, are inconsistent because of stent infections and recurrent bleeding. Therefore, close patient surveillance and cooperation among the treating specialists is necessary.·
