Varicose veins are operated on under a microscope, with the operative area located in the groin area, and there is usually no damage to the penis. The first step is to locate the spermatic cord slightly above the inguinal ligament, and then make an incision of about 2-3 centimeters in length to bluntly detach the spermatic cord, incise the extraspermatic levator muscle and spermatic cord sheath membrane, and then detach the spermatic veins under the microscope, and then ligate them one by one. The main operation area of microscopic hypospadias ligation is located in the lower abdomen above the inguinal ligament, which does not involve the penile region and does not operate on the penis, thus it will not cause damage to the penis. However, microscopic hypospadias ligation may mistakenly ligate the vas deferens or spermatic artery, which requires a higher level of surgical skill, and patients are advised to go to a specialized hospital for consultation.
