Comparative result of laparoscopic versus open varicocelectomy in children Introduction: Varicocele is an abnormal dilatation of the pampiniform plexus due to the inversion of venous blood flow within spermatic veins. In our country, there is currently no comparative studies for open and laparoscopic varicocelectomy in children and adolescents. Therefore, we need to perform a comparative study of surgical methods. Methods and materials: The case records of 61 patients were retrospectively reviewed рostoperative recurrence, complications, duration of surgery, hospital stay and cost of surgery who underwent open and laparoscopic varicocelectomy between 1 January, 2012 and 1 January, 2018 at the department of pediatric urology, NCMCH. Results: The age range for both group was similar, 9 to 18 years, average age was 14 ± 2.1. In the first group, the operation time was 15-50 minutes, with an average of 28.6 ± 5.67 minutes, and 25-90 minutes, with an average of 49 ± 13.7 minutes for second group. Hospital stay in the first group were 3-8 days, with an average of 4.7 ± 0.89, and 3-5 days, with an average of 3.6 ± 0.76 for second group. Conclusions: Laparoscopic surgery has advantages over traditional open surgery, surgical incision is smaller, less postoperative pain, and a shorter postoperative recovery time. Therefore, in further laparoscopic varicovelectomy (Palomo procedure) may be more appropriate and effective method in children and adolescents.
