“Pipe Cutting Method” -the Iimprovement of Male Sterilization Operation

目的：评价切管法（输精管结扎改良术）的临床效果。方法：采用切管法（小针头固定输精管结扎改良术）对600例年龄在26岁～38岁之间的已婚男性进行绝育手术，并对受术者进行术后1年的随访观察，对受术者的妻子进行了术后2年的孕情跟踪。结果：精子消失率：术后6个月为96．7％，术后12个月为98％；避孕有效率：术后6个月为99．8％，术后12个月为99．7％，术后24个月为99．5％；随访观察的600例受术者术后无局部血肿，无附睾淤积，无痛性结节，受术者的手术结节非常小，日常生活中未有不适感。结论：切管法与直视钳穿法相比，避孕有效率无差别，切管法的并发症更低，切管法更加简单，手术更加微创，结扎对象更易于接受。切管法是一项值得提倡的男性绝育术。
