The effectiveness of various vasectomy techniques is reviewed, with a focus on methods used for vas occlusion. Spontaneous recanalization of the vas is more common than generally recognized and is often transient. Simple ligation and excision has an unacceptably high risk for failure. Techniques that include cautery seem to have a lower risk for failure than techniques that do not include cautery. There is insufficient evidence to recommend a particular standardized cautery technique, but adding fascial interposition to cautery seems to be associated with the lowest risk for failure.
本文综述了各种输精管结扎术的有效性，重点关注输精管闭塞的方法。输精管自发再通比一般认为的更为常见，且通常是短暂的。单纯结扎和切除的失败风险高得令人难以接受。与不包括烧灼术的技术相比，包括烧灼术的技术失败风险似乎更低。目前尚无足够证据推荐特定的标准化烧灼术技术，但在烧灼术中增加筋膜置入似乎与最低的失败风险相关。
