A comparison of loupe-assisted and non-loupe-assisted subinguinal varicocelectomy.

INTRODUCTION

Varicocele is a treatable aetiology of male infertility. Magnification with surgical loupe has been associated with improved outcome and reduced morbidity than the conventional technique without magnification.

OBJECTIVE

To compare the outcomes of two techniques of subinguinal varicocelectomy, with a surgical loupe and without.

PATIENTS AND METHODS

This was a prospective randomised hospital-based study. Forty-six patients were randomised to two arms - Group A: loupe-assisted subinguinal varicocelectomy (LASV) and Group B: open subinguinal varicocelectomy without Loupe (OSV). They all had their semen and hormonal parameters compared preoperatively and at 3 and 6 months postoperatively. Post-operative complications were also assessed. P < 0.05 was considered statistically significant.

RESULTS

The mean age was 38.28 ± 4.55 years with a range of 27-46 years. The mean age in Group A was 37.35 ± 4.68 and 39.22 ± 4.33 years in Group B. There was an improvement in motility, sperm count and concentration in both the groups at 3 and 6 months (P < 0.05). However, there was no difference in these parameters on comparison of the two groups at 3 and 6 months (P > 0.05). Follicle-stimulating hormone decline was significant in the OSV group at 3 and 6 months, P = 0.010 and 0.021, respectively. There was no difference in other hormonal parameters both at 3 and 6 months (P > 0.05). The pregnancy rate in each arm of study was 4.3%. All complications occurred in Group B.

CONCLUSION

Both techniques resulted in improvement in seminal fluid parameters. All complications occurred in the arm that had subinguinal varicocelectomy without loupe. Loupe-assisted subinguinal varicocelectomy is safe and effective.
