摘要目的:探讨β刀(一种等离子针状电极)辅助腹腔镜治疗复杂型膀胱阴道瘘(VVF)的技术方法及临床应用价值。方法:回顾性分析2025年4月解放军总医院收治的1例复杂型VVF患者的临床资料，患者年龄36岁，子宫切除术后漏尿2个月。CT尿路造影排除输尿管瘘，膀胱镜显示膀胱后壁2 cm瘘口，双侧输尿管开口紧邻瘘口。手术先行经尿道β刀切开瘘口边缘并分离输尿管口，贯通膀胱后壁至腹腔；再行腹腔镜分离，缝合关闭瘘口并以大网膜覆盖加固。结果:手术时间共计180 min(其中β刀操作30 min)，术中估计出血量约为50 mL。术后留置导尿管3周，拔除尿管后排尿正常，随访4个月无漏尿。结论:β刀辅助腹腔镜修复复杂型VVF具有操作精确、创伤小、恢复快的优点，国内外未见类似报道，本术式为复杂型VVF的治疗提供了新方法。

abstractsObjective:To explore the technique methods and clinical application value of β-electrode (a plasma needle shape electrode) assisted laparoscopic repair of complex vesicovaginal fistula (VVF).Methods:Clinical data of one patient with complex VVF admitted to Chinese PLA General Hospital in April 2025 was retrospectively analyzed. A 36-year-old female presented with urinary leakage 2 months after hysterectomy. Computed tomography urography excluded ureterovaginal fistula. Cystoscopy revealed a 2 cm fistula on the posterior bladder wall with both ureteral orifices adjacent to the fistula edge. The procedure involved two steps: first, transurethral β-electrode pretreatment was performed to protect the ureteral orifices and create a passage from the bladder to the abdominal cavity. Then, laparoscopic separation, suture closure of the fistula, and omental flap coverage were conducted.Results:Total operation time was 180 min (the time of β- electrode operation was 30 min) with intraoperative estimated blood loss of 50 mL. The catheter was removed 3 weeks postoperatively, and the patient voided well without leakage during 4-month follow-up.Conclusions:β- electrode assisted laparoscopic repair of complex VVF have the advantage of precise manipulation, minimal invasion and rapid recovery. No similar technique have been reported domestically or internationally. This technique provides a new approach for the treatment of complex VVF.
