Objective To evaluate the therapeutic effect of endovascular electrocoagulation (EE) for low-position spermatic vein under a microscope. Methods A retrospective analysis was conducted on the clinical data of 314 patients with varicocele who underwent surgery Guangdong Provincial Corps Hospital of Chinese People’s Armed Police Force from January 2016 to October 2020. According to the surgical technique, the patients were divided into an EE group (n=155) and a spermatic vein ligation (TL) group (n=159). The operation time, postoperative hospital stay, perioperative complications (e.g., scrotal edema, pain), and the incidence of long-term complications at 12-month follow-up (e.g., hydrocele, epididymitis, recurrence, testicular atrophy) were compared between the two groups. Results The mean operation time was significantly shorter in the EE group (66.45±14.49 minutes) than in the TL group (81.89±12.36 minutes), and the postoperative hospital stay was (4.97±1.11) d, shorter than that of TL group (5.37±1.30) d, with statistically significant differences (P<0.05) . The incidence of postoperative scrotal edema was 1.29% (2/155) in the EE group, lower than the 5.03% (8/159) in the TL group, but the difference was not statistically significant (χ2=3.41, P=0.065). No significant differences were found between the two groups in postoperative pain Numerical Rating Scale (NRS) scores, incidence of hydrocele EE 0.65% (1/155) vs TL 1.89% (3/159), epididymitis EE 4.52% (7/155) vs TL 4.40% (7/159), P＞0.05, recurrence rate EE 1.94% (3/155) vs TL 2.52% (4/159), or testicular atrophy EE 0.65% (1/155) vs TL 0%,P＞0.05). Conclusions Endovascular electrocoagulation for low-position spermatic vein under a microscope is a safe and effective surgical method. Compared with traditional ligation, it can significantly reduce operation time, potentially decrease the risk of postoperative scrotal edema, and achieve comparable long-term outcomes, offering advantages of simpler operation.
