Varicocele surgery is a low-risk procedure, with risks equal to those of appendectomy, so the risks are relatively low. However, accidents do occur with any surgery, including accidents with anesthesia or the occurrence of bleeding. Surgery for varicocele is very mature and is accomplished by a variety of minimally invasive surgical methods. The damage to the body is almost minimal and the amount of bleeding is very low, so the level of risk during surgery is very low. Even for low-risk procedures, a detailed preoperative evaluation is still required, which includes the patient’s coagulation function, blood count and their heart, liver and kidney functions, and whether there are any potential risks to the relevant organs, and the evaluation is not abnormal before the procedure can be scheduled. The surgery is performed under general or semi-anesthesia, and different anesthesia is chosen depending on the type of surgery. General anesthesia and semi-body anesthesia are also very safe. After a comprehensive assessment, if the doctor can perform the surgical treatment after the assessment, the patient’s physical condition can tolerate the risks associated with the surgery, and it is a very safe surgical procedure.
