目的：介绍一种便于精确缝合的输精管吻合术技术。材料和方法：该技术包括用微尖标记笔在输精管切断端放置“微点”来标示计划的缝合出口点。匕首微点放置在12、3、6和9点的位置。在前面的4个点中的每个点之间放置4个附加点。每一次吻合使用8条粘膜缝线(双臂10-0单丝缝合，双匕首)。吻合采用8条肌线(9条单丝)和6条至8条(单丝6条)吻合血管鞘。结果：连续194例，通畅率99.5%。观察前100例受试者的妊娠率为54%(粗)和%(不包括女性因素不孕)。结论：微点技术通过精确地映射每条缝线，确保了缝线的精确放置，并促进了不同直径的管腔的吻合。微点法将规划和布局分开。使用微点技术的通畅率接近100%。
Purpose: A technique of vasovasostomy that facilitates precision suture placement is presented.Materials and Methods: The technique involves mapping of the planned suture exit points with ''microdots'' placed on the cut ends of the vas deferens with a microtip marking pen.dagger Microdots are placed at 12, 3, 6 and 9 o'clock positions. Four additional dots are placed between each of the previous 4 dots. Exactly 8 mucosal sutures (double armed 10-zero monofilament sutures double dagger) are used for each anastomosis. The anastomosis is completed with 8 muscularis sutures (9-zero monofilament) and 6 to 8 sutures (6-zero monofilament) approximating the vasal sheath.Results: In a series of 194 consecutive vasovasostomy procedures using this technique a patency rate of 99.5% was achieved. Pregnancy rates of 54% (crude) and 64% (excluding female factor infertility) were observed for the first 100 subjects of this cohort.Conclusions: The microdot technique ensures precision suture placement and facilitates the anastomosis of lumens of discrepant diameters by exact mapping of each planned suture. The microdot method separates the planning from the placement. Patency rates using the microdot technique approach 100%.
