采用三种残端处理术式完成的1185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28例查见精子,其中12例配偶受孕,精子阳性率为2.43%,再孕率1.03%。经统计学处理三种术式的精子阳性率和再孕率无显著性差异。三个残端处理组的并发症发生率为0.67%,各组之间的差异亦无显著性。本研究提示,三种输精管残端处理术式对节育效果和安全性无明显影响,但与手术者的经验和技术水平有一定的关系。 A prospective study of 1185 cases of vasectomy performed using three stump procedures showed that 28 cases were found sperm at 2 years of follow-up, with 12 spouses pregnant and sperm positive rate of 2.43% Pregnancy rate 1.03%. There was no significant difference in sperm positive rate and pregnancy rate between the three surgical methods. The incidence of complications in the three stump treatment groups was 0.67%, with no significant difference between the groups. This study suggests that the three types of vasectomy stalks have no significant effect on the birth control effect and safety, but have some relationship with the surgeon’s experience and technical level.
