This study aimed to evaluate a simplified vasovasostomy procedure that shortens the operative time. This was a retrospective (non-randomized) study of men who underwent bilateral vasectomy and consulted for vasovasostomy (02/2014-08/2016). Eight interrupted sutures were used for one-layer full-thickness vasal anastomosis over a 20 or 22 G catheter temporarily inserted in the lumen of the anastomotic site as a stent. Control patients underwent double-layer vasovasostomy. The surgery was significantly shorter in the one-layer group (n = 23) (62 ± 8 vs. 133 ± 15 min, P < 0.001 vs. the two-layer group, (n = 19)). There was no difference in patency between the two groups (95.7 vs. 94.7%, P > 0.999). There was one case of epididymitis in each group. There were no complications like bleeding, scrotal hematoma, hydrocele, or infection. Low-power microscopic one-layer vasovasostomy with stent was simple and had a short operation time. The patency could be similar to that of two-layer vasovasostomy, but prospective studies are necessary for confirmation.

这项研究旨在评估简化的血管吻合术，缩短手术时间。这是对接受双侧输精管结扎术并接受了输卵管吻合术的男性进行的回顾性研究（非随机）。（02 / 2014-08 / 2016）使用八根间断缝合线，将一根20或22 G导管临时插入吻合部位的内腔作为支架，用于一层全厚度的血管吻合术。对照患者进行了双层血管吻合术。单层组的手术时间明显缩短（n  = 23）（62±8 vs. 133±15 min，P  <0.001 vs两层组（n  = 19））。两组之间的通畅度没有差异（95.7 vs. 94.7％，P > 0.999）。每组有1例附睾炎。没有出血，阴囊血肿，鞘膜积液或感染等并发症。带支架的低倍镜显微单层血管吻合术简便易行，手术时间短。通畅性可能类似于两层血管吻合术，但前瞻性研究对于确证是必要的。
