Microscopic varicocele ligation surgery for varicocele has the lowest recurrence rate and is a minimally invasive procedure with the best results. The specific surgical approach: 1. the patient needs to be under semi-body or general anesthesia, in the supine position. 2. the surgical incision is located about 2 cm above the pubic symphysis on the side of the varicocele, which is a 2 cm incision above the root of the scrotum. 3. the spermatic cord is freed within the incision and pulled outside the body, and the varicose veins are searched for under the microscope, as well as the arteries and lymphatic vessels in the spermatic cord. 4.The artery and lymphatic vessels are kept intact and all varicose veins are ligated to complete the operation. 5.After checking that there are no missed veins or bleeding, the spermatic cord is put back in its original position and the incision is closed in turn to finish the operation.
