N/A unilateral inguinal hernia. Intervention 1: Intervention Group 1 (Lichtenstein Tension-Free Mesh Repair): After primary open incision and dissection of spermatic cord, the hernia sac will be identified and isolated. A 7.5 × 15 cm piece of polypropylene mesh will be placed on posterior wall of inguinal canal. The first medial-most stitch fixes the mesh 2 cm medial to the pubic tubercle, where the anterior rectus sheath inserts into the pubic bone. The same suture is then used as a continuous suture to fix the lower edge of the mesh to the free lower border of inguinal ligament up to a point just lateral to the internal ring. With the mesh kept lax, its upper edge is then fixed to the rectus sheath and the internal oblique aponeurosis with two or three interrupted nonabsorbable sutures. The two tails are then tucked together and fixed to the inguinal ligament just lateral to the internal ring, thus creating a new internal ring made of mesh. Intervention 2: Intervention Group 2 (Read-Rives procedure): Read-Rives procedure is performed through the longitudinal opening in the transversalis fascia in the inguinal floor. At first, the prepritoneal space is dissected and the spermatic cord is parietalized. Afterwards, a 10×15 cm of mesh is implanted in front of the peritoneum, and the mesh is held in place with 2/0 nylon sutures to pubic tubercle, cooper ligament, and psoas muscle. Finally, the fascia is closed over the mesh.
