Cryptorchidism surgery requires a 2-3 cm incision, which is relatively short and located in the inguinal region, and is equivalent to open surgery. Open surgery is suitable for low cryptorchidism, that is, the testicle is located in the inguinal area. Open surgery is not suitable for high cryptorchidism. Patients with high cryptorchidism are those whose testicles are located above the inguinal region, so open surgery is no longer suitable and laparoscopic surgery is recommended. Laparoscopic surgery requires three holes to be made in the lower abdomen, where lenses, operating forceps, ultrasonic knives and other equipment can be put in respectively, to be able to search and probe the testicles in a relatively large area before they can be found and further pulled back into the scrotum.
