Surgery for cryptorchidism in babies can usually return to normal in a week. There are various surgical methods available, and an ultrasound or CT examination must be done effectively before the surgery. Find the location of the cryptorchid. The vast majority of patients with cryptorchidism are in the inguinal canal, retroperitoneum or scrotal inlet; for the inguinal canal or scrotal inlet, the surgery is relatively superficial and easy to do, and the testicle can be effectively pulled down to the scrotum and effectively fixed in the scrotum, and the surgery recovery is relatively fast. For retroperitoneal cryptorchidism, the surgery may need to be performed through laparoscopic approach, which is relatively less invasive. Through laparoscopy, the cryptorchid can be found behind the peritoneum and sent into the sac for effective fixation. The recovery from the surgery is fast and can generally return to normal in a week.
