Use of endoscopy in the management of postoperative ureterovaginal fistula.

The aim of the study was to evaluate endourological techniques in the management of iatrogenic ureterovaginal fistula. Seventeen patients referred to us after gynecologic surgery were diagnosed as having iatrogenic ureterovaginal fistula. First, retrograde double-J stenting was tried. If this failed, percutaneous nephrostomy using an antegrade double-J stent was performed. If this also failed, open surgical repair was performed. The retrograde double-J stent bypassed the fistula in 2 patients (11.8%). Percutaneous nephrostomy was performed in the remaining 15. The antegrade double-J stent bypassed the fistula in another 2 of these patients (11.8%). Open surgical repair was performed in the remaining 13 patients (67.5%) (direct ureteroneocystostomy) with nipple valve in 11 patients and Boari flap with psoas hitch in 2 patients). Of all patients, 2 had ureteral stricture, one after antegrade double-J stenting and the other after open repair. It was concluded that early intervention is recommended in the treatment of iatrogenic uretrovaginal fistula, causing minimal morbidity and discomfort, and being less expensive.
