Purpose
The two most common procedures for open tension-free groin hernia repair with prosthetic mesh are the Lichtenstein operation and the mesh plug (Rutkow–Robbins) technique. Our study evaluated these two techniques on testicular blood flow and volume, and sperm function in young adults.
Methods
We randomized operation types with a systematic sampling method, and handled consecutive patients of age 20–30 years having unilateral inguinal hernia repair at our institution from March to August 2008. The study subjects were divided into the Lichtenstein group (LG) and the mesh plug group (MPG). All subjects received color Doppler ultrasonography to determine testicular volume and resistive index (RI) the day before surgery and 3 months postoperatively by a physician blinded for the type of planned or performed operation. Spermiograms done preoperatively and at 3 months postoperatively measured sperm concentration and the rate of progressive motility.
Results
Sixty-four patients met the study criteria, with 32 patients each in the LG and MPG. RI levels were elevated postoperatively in both the LG (P = 0.027) and MPG (P = 0.012); there was no significant alteration in terms of testicular volume and spermiogram in the LG and MPG.
Conclusion
The Lichtenstein and mesh plug techniques in unilateral inguinal hernia increase the RI level significantly in the early postoperative period, but do not have a significant effect on sperm concentration and the rate of progressive motility.
