用７种残端处理技术完成的２３７３例输精管结扎术的一项前瞻性研究表明，术后２年随访时共有７８例查见精子，其中２７例配偶受孕，精子阳性率为３．２９％，再孕率１．１４％。各种术式的精子阳性率：附睾端开放加包埋０．５５％，两端单纯结扎１．４１％，结扎加筋膜包埋２．６３％，石碳酸烧灼３．１７％，精囊端折叠３．７１％，结扎加电灼４．７５％和不作包埋的附睾端开放７．５３％。经统计学处理各种术式的精子阳性率之间差异有非常显著意义（Ｐ＜０．０００１）。由不同手术者完成的相同术式结果分析表明，除石碳酸烧灼组以外，其余各组皆无组内差异。７个残端处理组的并发症发生率有显著差异（Ｇ＝２０．９６，Ｐ＜０．０１）、其中不作包埋的附睾端开放组并发症发生率达２．１７％，折叠组的出血和感染等发生虽少，但术后近期局部结节反应发生率达４．７７％。本研究表明，输精管残端处理方式的不同可能影响术后节育效果和安全性，但手术者经验和技术水平也起很大作用。
Abstract：A perspective study of 2373 vasectomies performed with 7 different technique of treatingthe cut ends of vas deferens showed that the overall recanalization rate and pregnancy rate were 3.29%(n=278) and 1.14%(n=227),respectively. The follow-up was carried out by checking semen at two yearspost-vasectomy. There was a highly significant difference in sperm positive rate with the 7 different tech-niqtue (P < 0.0001):open-ended with covering over 0.55%,standard technique 1. 41%, vasectomy withcovering over 2.63%,cautery of vas ends with phenol 3.17%, folding of the seminal vesicle 3.7l%,stan-dard technique plus electrocautery 4.75%, and open-ended without covering over 7.53%. No differencesof recanalization rate was found in each similar technique group done by different operators, except withthe phenol group. There was a significant difference in complication percentages with various technique(G=20.96, P<0.01).The present paper showed that the different technique of treating the cut ends of vascould afftect the efficacy and safety of vasectomy.
