If the sacrococcygeal bone is injured, it can damage the bowel and bladder function when damaging the sacral nerve. There are sacral nerves at the sacrococcygeal bone, and sacral nerves are the nerves that innervate the anorectum and bladder. If the sacrococcygeal bone is damaged, it may damage the sacral nerves, which may affect the damage to the bowel and bladder functions, so the nerves have to be avoided during the surgery in order to avoid the occurrence of complications. After the operation, we should monitor the condition, carry out wound care, and change the medicine regularly. After the operation, we should focus on whether there is any damage to the nerves, and if the nerves are injured, we should carry out treatment in time so as to avoid the further development of the condition, and the diet should be light, and appropriate nutrition should be supplemented to promote the recovery of the wounds.
