经尿道双极等离子电切术治疗女性膀胱颈梗阻的临床分析

目的探讨经尿道双极等离子电切术治疗女性膀胱颈梗阻的疗效。方法采用经尿道膀胱颈电切术（TURBN）加钩状电极颈口切开治疗63例女性膀胱颈梗阻。术前均行尿流动力学检查和膀胱镜检查,45例行经尿道膀胱颈后唇切除术,18例行经尿道膀胱颈后唇切除术加膀胱颈12点位纵行切开术。结果平均手术时间15（10～46）min,失血〈10ml,无水中毒及尿失禁发生。术后病理报告为膀胱颈黏膜下纤维组织增生伴玻璃样变性,部分平滑肌变性增生及黏膜下炎性细胞浸润。本组63例均获随访,平均13.5（1～24）个月,治疗后生活质量评分由4.3±1.2降至1.6±0.5（P〈0.01）,最大尿流率由4.8±2.6ml/s升至19.2±5.8ml/s（P〈0.01）,残余尿量由320.5±168.5ml降至26.3±16.4ml（P〈0.01）。结论经尿道双极等离子电切术是治疗女性膀胱颈梗阻的有效方法。
