Microsurgical vasovasostomy for the reversal of elective bilateral segmental vasectomy (vasectomy, vas ligation) was done in 57 patients (61 operations) between May 1977 and March 1984. The length of time between elective segmental vasectomy and subsequent vasovasostomy ranged from 12 to 216 months; the longest period between vasectomy and vasovasostomy resulting in a subsequent pregnancy was 108 months. The patency rate was 83%, with 51% of these patients fathering one or more children (overall pregnancy rate of 41%). Unlike previous studies, ours showed no positive correlation between the presence of postvasectomy sperm granulomas and either patency or pregnancy rate after microsurgical vasovasostomy. The major factor that seemed to affect the success of the procedure was the number of years between vas ligation and vasovasostomy.
1977年5月至1984年3月期间，对57例患者（共进行了61次手术）实施了显微外科输精管吻合术，以恢复选择性双侧节段性输精管结扎术（输精管结扎术、输精管结扎）。选择性节段性输精管结扎术与随后的输精管吻合术之间的时间间隔为12至216个月；输精管结扎术与输精管吻合术之间导致随后怀孕的最长时间为108个月。通畅率为83%，其中51%的患者育有一个或多个子女（总体妊娠率为41%）。与以往的研究不同，我们的研究表明，输精管切除术后精子肉芽肿的存在与显微外科输精管吻合术后的通畅率或妊娠率之间没有正相关。似乎影响该手术成功的主要因素是输精管结扎术与输精管吻合术之间的年数。
