Ureteroarterial fistula treated by endovascular stent placement.

After several imaging tests, an uretero-arterial fistula is confirmed by angiography and treated with a coated stent. Uretero-arterial fistula poses a diagnostic challenge, requiring a multidisciplinary approach through clinical suspicion and interventional procedures.
