Angiographic nephrectomy as a nonsurgical treatment of ureteral fistulas

Renal artery embolization with ethanol and gelfoam for the treatment of ureteric fistulae with one year follow-up

Two patients with ureteric fistulae who were unfit for reconstructive surgery were treated by renal ablation using intra-arterial ethanol, gelfoam fragments and in one case coils. In both cases the fistulae dried-up on the same day and both patients are well and normotensive a year later. Our conclusion is that renal ablation by arterial embolization with ethanol can be a valuable alternative to surgery to treat ureteric fistulae in patients who are poor surgical risks.

Nephrectomy in situ: treatment of ureteral fistula due to progressive malignancy

The authors report 2 patients with recurrent retroperitoneal neoplasms in whom ureteral fistulas were treated successfully by percutaneous transcatheter embolization of the renal artery with absolute ethanol. Angio-occlusive nephrectomy is suggested as an alternative to surgical nephrectomy in seriously ill and high-risk patients to preserve their quality of life.

Treatment of urinary fistulas after resection of horseshoe kidneys by selective arterial embolization

Two patients presenting with urinary fistulas following partial resection of hydronephrotic kidneys were successfully treated with selective arterial embolization causing functional ablation of the remaining renal parenchyma. This technique is simpler than surgical reexploration.

Renal artery embolization to control urinary cutaneous fistula after partial resection of a horseshoe kidney

We describe a patient with a chronic urinary cutaneous fistula following partial nephrectomy of a previously separated horseshoe kidney, who was treated successfully by stainless steel coil embolization of the renal artery. Thus, a major reoperation was avoided.
