A non-incision method of vas occlusion based on the percutaneous injection of polyurethane elastomer solution to form plugs is described. The results are based on clinical experience in 12,000 men in which only 56 cases of minor complications were recorded. Follow-up of 500 men for up to 3 years demonstrated an azoospermia rate of 98%. Plugs have been removed from 86 men and, to date, 51 have made their wives pregnant. In those from which the plugs have been removed for more than 1 year (n = 31), the pregnancy rate is 100%.
描述了一种基于经皮注射聚氨酯弹性体溶液形成栓塞的非切开式输精管闭塞方法。结果基于对12000名男性的临床经验，其中仅记录了56例轻微并发症。对500名男性进行了长达3年的随访，结果显示无精子症发生率为98%。已从86名男性体内取出栓塞，迄今为止，其中51名男性的妻子已怀孕。在栓塞取出超过1年的男性中（n = 31），怀孕率为100%。
