We evaluate the temporal parameters of patency following vasoepididymostomy and vasovasostomy.
A series of consecutive and concurrent vasoepididymostomies (100) and vasovasostomies (100) performed by a single surgeon (M. G.) was reviewed.
Patency rates following vasoepididymostomy and vasovasostomy were 65% and 99%, respectively (p < 0.001). Motile sperm were observed at a mean of 5.8 +/- 0.8 months (standard error) following vasoepididymostomy and 2.1 +/- 0.2 months following vasovasostomy (p < 0.01). Late failure rates were 21% for vasoepididymostomy and 12% for vasovasostomy. Pregnancy rates following vasoepididymostomy and vasovasostomy were 21% and 52%, respectively.
Patency is rapid following vasovasostomy but requires 12 or more months following vasoepididymostomy. Intervention for azoospermia is appropriate 6 months after vasovasostomy and 1 year after vasoepididymostomy. Intraoperative cryopreservation of sperm in men undergoing vasoepididymostomy and postoperatively in all men with motile sperm will maximize fertility options.
我们评估了附睾输精管吻合术和输精管吻合术后通畅的时间参数。
回顾了由单一外科医生（M.G.）进行的一系列连续且同期的附睾输精管吻合术（100例）和输精管吻合术（100例）。
附睾输精管吻合术和输精管吻合术后的通畅率分别为65%和99%（p<0.001）。附睾输精管吻合术后平均5.8±0.8个月（标准误）观察到活动精子，输精管吻合术后为2.1±0.2个月（p<0.01）。附睾输精管吻合术的晚期失败率为21%，输精管吻合术为12%。附睾输精管吻合术和输精管吻合术后的妊娠率分别为21%和52%。
输精管吻合术后通畅迅速，但附睾输精管吻合术后需要12个月或更长时间。输精管吻合术后6个月、附睾输精管吻合术后1年对无精子症进行干预是合适的。对接受附睾输精管吻合术的男性术中冷冻精子，对所有有活动精子的男性术后冷冻精子，将使生育选择最大化。
