Comparison of Treatment Outcomes of Different Spermatic Vein Ligation Procedures in Varicocele Treatment.

In this study, 4 different spermatic vein ligation procedures for varicocele (VC) treatment were compared based on recurrence rate, postoperative complications, and semen quality. Between January 2012 and May 2013, a total of 345 male patients with VC were recruited at The First Affiliated Hospital of Soochow University. Patients were performed by different ligation procedures, and they were divided into 4 groups: laparoscopic varicocelectomy group (LV group: n = 84), microscopic inguinal varicocelectomy group (MIV group: n = 85), microscopic retroperitoneal varicocelectomy group (MRV group: n = 86), and microscopic subinguinal varicocelectomy group (MSV group: n = 90). In MSV group, the operative time was 55 ± 6.9 minutes, which was significantly longer than LV, MIV, and MRV groups (P < 0.05). Recurrence rate in LV group was at 11.9%, the highest rate observed compared with the MIV, MRV, and MSV groups (P < 0.05). Scrotal edema and testicular atrophy in MSV group were markedly decreased (P < 0.05), and scrotal pain was relieved in almost all patients in the MSV group at a significantly higher rate than LV, MIV, and MRV groups (P < 0.05). Sperm concentration, sperm count of grades a + b, and sperm motility (%) in the MSV group were sharply higher than LV, MIV, and MRV groups (all P < 0.05). Our study indicates that MSV is the most beneficial of the 4 spermatic vein ligation procedures and may be offered as the first-line treatment for VC in infertile men.
