Percutaneous management of benign ureteral strictures and fistulas.

The percutaneous methods of management of benign ureteral strictures or fistulas have developed as a natural evolution of percutaneous nephrostomy and angiographic techniques. We review our 5-year experience, which includes 18 patients with 19 benign ureteral strictures and 12 patients with ureteral fistulas. In the majority of the patients the ureteral strictures occurred at sites of surgical reconstruction or endoscopic manipulation. All fistulas resulted from surgical injury. In 10 of the 12 patients (82 per cent) the fistulas healed without development of a stricture or need for further intervention. Patients with short ureteral strictures had a high incidence of success and they usually were the best candidates for percutaneous manipulation. The long strictures usually were of longer duration and they were less likely to be managed successfully percutaneously. Failure of percutaneous dilation did not impede subsequent surgical management. Percutaneous management often is a reasonable initial step in the treatment of ureteral strictures and fistulas.
