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.
输尿管阴道瘘（UVF）对患者和医生来说都是一个具有挑战性的问题，尤其是对于那些因恶性肿瘤接受过放疗的患者。UVF可能与涉及子宫的手术同时发生。据报道，瘘管修复的成功率为70%-100%，在未接受放疗的患者中效果最佳。同时，在部分患者中使用输尿管支架进行保守治疗，报道的成功率为71%。我们报告了一例24岁因宫颈癌手术和放疗导致输尿管阴道瘘的女性病例。该患者通过植入Memokath 051支架（丹麦PNN Medical A/S公司）成功治愈，这是一种热膨胀镍钛合金支架。在3年的随访期内，患者完全控尿。在此期间，由于功能障碍，Memokath支架更换了两次。
