Prostheto-Ureteral Fistula: A Rare Complication After Aortic Graft Surgery

Prostheto-ureteral fistula after aortic graft surgery is a potentially life-threatening, rare pathology. We report the successful treatment of a prostheto-ureteral fistula that caused hematuria with hemorrhagic shock in two patients by explantation of aortic prosthetic grafts and implantation of a silver-bonded prosthetic graft (Intergard S, Intervascular®). These cases show that this surgical procedure is effective, and that straightforward diagnostic procedures are necessary to initiate correct therapeutic approach without delay. Various different possible risk factors for the formation of a prostheto-ureteral fistula are also discussed.
