Antegrade subinguinal sclerotization with temporary clamping of the spermatic cord: a new surgical technique for varicocele

Objectives : The purpose of our study was to evaluate the duration, effectiveness, and complications associated with a new operating technique for varicocele, using a subinguinal surgical approach and antegrade sclerotization of the spermatic veins. Methods : A total of 756 varicocele patients who came under our care for infertility underwent surgical treatment with our technique. The diagnosis was based on clinical examination and confirmed by color-Doppler ultrasound of the spermatic cord. Only patients with continuous basal reflux inside the left spermatic vein detected in orthostatism underwent operation. The Colpi technique was used, which consists of a subinguinal incision with suspension of the spermatic cord; cord clamping for 8-10 minutes using two elastic bands; and injection of 1.5-3 mL of sclerosing agent during induced ischemia without any intraoperative radiological control. Results : The average operating time was 25 minutes (range: 18-45 minutes). At the 3-month postoperative follow-up, there were 15 cases of persistent reflux (1.9%), 6 cases of hydrocele requiring surgical correction (0.7%), and 50 cases of fibrotic sequelae of penile lymphangiitis (6.6%). Conclusions : The new technique was more effective than the previous ones, with the exception of the microsurgical technique, which, however, takes 2-3 times longer to perform. The only significant complication was superficial single-vessel lymphangiitis of the penis, which resolved within 3 months with no apparent consequences. In conclusion, this new operating technique for varicocele is simpler to perform and may be effective compared with other techniques.
