Psychological factors: patients with sacral tumor will not take the initiative to defecate when they are in a state of tension and anxiety for a long time, and then the symptoms of incontinence will appear. 2. Nerve damage: in sacrectomy, the sacral nerve in the tumor can not be preserved, and it is very difficult to restore the nerve function to the completely normal state after the operation, and the sacral nerve damage will cause the incontinence symptoms. 3.
