To investigate the safety and efficacy of a novel approach of microscopic subinguinal varicocelectomy with a "pulling" strategy. Fifty-two male patients with varicocele were enrolled in this study. Twenty-six patients underwent conventional microscopic subinguinal varicocelectomy, whereas the remaining 26 patients accepted our novel approach of treatment. In this method, with a subinguinal incision, we dissociated the spermatic cord from the external ring. And thus we pulled the spermatic cord down and away from the external ring and exposed the spermatic cord that initially was proximal to the external ring in the surgical field. The remainder of the procedure was similar to that of the conventional method. Follow-up was made at 1 and 3 months. Postoperative complications were recorded and sperm parameters were evaluated by semen analysis. Fewer vein branches were ligated in the novel method group compared with the conventional method group (6.9 ± 2.1 vs 9.8 ± 2.2, P < .001; t = -5.316). There was no significant difference in the number of testicular arteries or lymphatic ducts between the 2 groups. The mean microsurgical operative time in the novel method group was significantly shorter than that in the conventional method group (34.7 ± 6.5 minutes vs 45.7 ± 8.8 minutes, P < .001; t = -5.621). The incidence of postoperative complications was similar for the 2 groups. There was no significant difference regarding semen quality improvement between the 2 groups. This study demonstrates that our novel approach of microscopic subinguinal varicocelectomy with a "pulling" strategy significantly reduces the number of internal veins to ligate and shortens operating time, with no increase in complications. It is a safe and effective method of varicocele treatment.
