Novel patented minimally invasive technique for surgical treatment of varicocele: technique overview

Abstract

Introduction. Many methods have been proposed for the surgical treatment of varicocele, the most of which is of historical significance. At present, there is no consensus in favor of one or another method of surgical treatment of varicocele, which determines the relevance of further research.Objective. To evaluate the effectiveness of a new minimally invasive method of surgical treatment of varicocele using the author's method.Materials & methods. The study enrolled 763 patients aged 18 – 46 years (mean age 26.3 years) with varicocele who underwent testicular vein subinguinal ligation according to the author's technique. Inclusion criteria: varicocele grades 1 – 3, aged ≥ 18 years, semen abnormalities according to semen analysis and dilated spermatic cord veins according to ultrasound, retrograde blood flow according to Doppler ultrasound. Exclusion criteria: previously operated patients with recurrent varicocele, patients with May-Thurner syndrome and bilateral varicocele. The examination included eight control points: before surgery and 3, 6, 12, 24, 36, 48, and 60 months after surgery. Physical scrotal examination with Valsalva test, semen analysis, and Dopper scrotal ultrasound were performed at the control dates.Results. The average surgery time was 15 min (10 – 30 min). All patients were discharged 1 to 2 days after surgery. At follow-up for 60 months, patients showed improvement in spermatogenesis / or no progression of semen abnormalities during follow-up after surgery based on clinical, laboratory and instrumental studies (semen analysis, ultrasound / Doppler ultrasound); no data on testicular hypotrophy, hydrocele were revealed. A scrotal haematoma was detected in one patient in the early postoperative period. Recurrent varicocele (1.4%) was detected in 11 patients during the follow-up period.Conclusion. The technique is effective, easily reproducible, characterised by a low rate of recurrence and postoperative complications.
