Precautions for testicle removal: If the testicle must be removed due to disease or necrosis, the patient and his family must agree and sign before the operation. Because the testicles are important organs that men must have to maintain their physiological functions, they must be signed at the same time. In addition, the spermatic cord and vas deferens are ligated separately during the resection process to avoid obstruction and pain for the patient after the operation. If there are conditions, the prosthesis of the testicles can be installed after the operation to avoid causing the patient’s psychosexual disorder. After surgery, if bilateral testicular resection, must do androgen supportive therapy. After the operation, the wound should be avoided to be contaminated by urine, and the patient can take a bath more than 1 month after the operation.
