Abstract: Objective To compare the two micro-varicocelectomy method，investigate the best methods of operation. Method A total of 191 patients with varicocele admitted to our hospital from May 2016 to May 2019 were randomly divided into two groups using the random number table method. Group A(n=72) was selected through the superficial inguinal ring approach, and group B (n=119) was selected through the inguinal approach.Compare their operative time,number of vein,number of lymphatics, side effects,results after operation,spouse partner rate of pregnancy. Result Length of incision:group A：(1.5±0.30)cm，group B：(2.0±0.35)cm(P＜0.05).Operation time:group A：(40.5±6.8)min,group B：(30.2±4.8)min(P＜0.05).Vein ligation during operation:group A:mean(10±6.3)branches;group B:mean(7.2± 3.3)branches(P＜0.05).Lymphatics observed:group A：mean(4±2.3)branches；group B:mean(2.5±1.3) branches(P＜0.05).There was no testicular atrophy in both groups after operation, and 2 cases in group A had mild testicular hydrocele. The semen quality of the two groups was significantly improved after operation compared with that before operation, and the difference was statistically significant(P＜0.05).Sperm period comparison between the two groups, there was no statistically significant difference (P>0.05). Group A recent recurrence in 1 case, 2 cases, group B is similar between the two groups have no statistical significance (P>0.05). There were 33 pregnant spouses in group A and 63 pregnant spouses in group B. There was no significant difference between the two groups(P＞0.05). Conclusion Two methods of microsurgery varicocelectomy are safe and effective for the treatment of varicocele.Superficial inguinal ring approach might be used to fat or second operation patients.The number of veins ligated through inguinal approach is less and the operation time is short, which is suitable for ordinary patients.
