When renal necrosis occurs, surgical resection is usually needed, because long-term presence in the body will induce infection and may induce septicemia. Surgical resection can be done either by open resection or laparoscopic resection. These two types of surgery have their own advantages and disadvantages, in which open resection is relatively traumatic, slow recovery, but the patient’s cardiopulmonary function requirements are lower, but also can choose anesthesia, such as epidural anesthesia, the patient can have a lighter financial burden. Laparoscopic surgery is relatively less traumatic, faster recovery, better aesthetics, but the operation requires general anesthesia to do, and the patient can not have more serious cardiac function abnormalities, such as angina pectoris, cardiac infarction, can not have serious pulmonary function disorders and cerebral infarction, etc., and the cost of the operation is relatively more. The type of surgery chosen needs to be decided according to the patient’s condition, which can be communicated with the attending physician.
