８１６例自愿接受输精管绝育术男子按照节育手术常规施行输精管结扎术，受术者随机均分为４个队列，分别施行不同的输精管残端处理方法：（１）单纯两断端结扎；（２）结扎加精索筋膜隔离；（３）结扎加苯酚涂灼；（４）电灼。术中以１：３０００新洁尔灭溶液每侧输精管５ｍｌ行精囊灌注，术后３年４种方法精子消失率分别为９０．０％（１８０／２００），９４．１％（１７５／１８６），９３．７％（１７９／１９１）及９４．５％（１７２／１８２），术后并发症为０．４％（３／８１６）。在此对输精管结扎术后自发再通问题进行了讨论，并认为１：３０００新洁尔灭溶液行精囊灌注是安全可行的。
816 cases of vas deferens who voluntarily accepted vasectomy Man underwent vasectomy routinely under the control of birth control. The patients were randomly divided into 4 cohorts, which were treated with different vasectomies: (1) Ligation plus spermatic cord isolation; (3) ligation plus phenol burning; (4) electrocautery. The intraperitoneal instillation of 5ml seminal vesicles in 1: 3000 BrdU solution on each side of the vasectomy was perfusion. The disappearance rates of sperm in four methods after 3 years were 90.0% (180/200), 94.1% (175/186), 93 respectively. 7% (179/191) and 94.5% (172/182) respectively. The postoperative complications were 0.4% (3/816). Here is the discussion of spontaneous recanalization after vasectomy and concluded that 1: 3000 benzalkonium bromide solution is safe and feasible for perfused seminal vesicles.
