The success rate of bilateral cryptorchid surgery is more than 95%. It is recommended that proper examination must be done before bilateral cryptorchidism surgery, and ultrasound should be done to clarify whether the cryptorchid testis is in the inguinal canal, retroperitoneum, or at the entrance of the scrotum. For bilateral cryptorchidism, laparoscopy is characterized by small trauma, fast recovery and less bleeding, which can be separated finely and effectively avoid the damage of testicular artery, spermatic cord as well as vas deferens, and can be performed at the same time as bilateral cryptorchid testicular exploration plus bilateral cryptorchid testicular descending and fixation surgery, which is the best way to treat the disease. Before the operation, effective attention must be paid to whether the cryptorchid testis has a tendency to become cancerous, and if cancerous, radical resection of both testes should be performed, which is the right choice.
