Microsurgical Subinguinal Varicocelectomy
In this procedure, a high-powered operating microscope is used to perform the varicocelectomy. The physician makes an incision in the groin and examines the veins with the microscope, then ligates and cuts all the problematic veins. It is the only method to ligate external and all internal spermatic veins, which is not possible by embolisation or laparoscopy
