Ureteroarterial and ureterosigmoid fistula associated with polyethylene indwelling ureteral stents.
Iliac artery-ureteral fistulas are uncommon, with less than 15 cases described in the literature. Ureterocolic fistulas have been described even less frequently. We report the first case of synchronous right ilioureteral and left ureterosigmoid fistulas associated with indwelling ureteral stents. The patient presented with massive sentinel gross hematuria, urosepsis and chronic anemia.
