title: Treatment of ureterovaginal fistula using a Memokath stent.
abstract: Ureterovaginal fistula (UVF) is a challenging problem for patients and doctors, especially in patients who have been treated by radiation for malignancy. UVF may occur in conjunction with surgeries involving the uterus. A success rate of 70-100% has been reported for fistula repair with the best results in non-radiated patients. Meanwhile, conservative treatment using ureteral stents in selected patients has resulted in reported success rates of 71%. We present the case of a 24-year-old woman with UVF due to surgery and radiotherapy for cervix cancer. The patient has been successfully treated with the insertion of a Memokath 051 stent (PNN Medical A/S, Denmark), which is a thermoexpandable, nickel-titanium alloy stent. The patient has been totally continent during a follow-up period of 3 years. The Memokath stent has been changed twice within this period due to dysfunction.
