The spermatic cord blood vessels and vas deferens may be damaged during cryptorchid testicular surgery in children, and postoperative testicular atrophy may occur, which may affect fertility. Some children with cryptorchidism may experience complications after surgery due to the relatively short spermatic cords during the operation and postoperative retraction of the testis, possibly to the inguinal region. If the testicle is found to have retracted into the inguinal region after surgery, and the presence of the testicle is not palpable in the scrotum, another surgical procedure is required. Minimally invasive surgery is now available for cryptorchid surgery, and the chances of testicular atrophy and retraction, among other things, are greatly reduced. After cryptorchid surgery, the scrotal ultrasound should be reviewed regularly to note the size and blood supply of the testicle.
