According to the current development of medical science, the success rate of high cryptorchidism surgery is over 95%. The vast majority of high cryptorchidism can be fixed to the scrotum in one go through the conventional testicular descent surgery. However, for some patients with short spermatic cord vessels, staged surgery may be required to complete the testicular descent or fixation surgery. For patients with short spermatic cord vessels, if they cannot be free into the scrotum, the spermatic cord can be severed and the testicle can be descended into the scrotum to use the blood supply from the vas deferens to nourish the testicle and promote its development. However, the spermatic cord is usually blocked during surgery to observe whether the testis is ischemic, and if the ischemia is not obvious, the spermatic cord can be severed and the testis can be lowered into the scrotum. However, in cases where ischemia is more pronounced after clamping the spermatic cord, testicular transplantation is recommended. The severed spermatic cord is anastomosed to the subabdominal vessels to complete the blood supply to the testis.
