The Management of Urinary Fistulas and Strictures with Percutaneous Ureteral Stent Catheters

Abstract
A method is described for percutaneous anterograde introduction of a ureteral stent catheter. The experience and treatment of 5 patients are reported: 2 ureterovaginal fistulas, 2 ureterocutaneous fistulas and 1 ureteral stricture. The capability of the technique to place a stent catheter in the presence of an almost complete separation of the ureter or through ureteral segments deformed by extensive cicatricial changes is emphasized. The method is advocated as an effective alternative to supravesical drainage in patients with ureteral fistulas and impaired healing potential of ureters devitalized by surgical stripping and/or radiation therapy.
