Fecal incontinence is a type of fecal disorder. Patients mainly present with uncontrolled bowel movements and increased frequency of stools, mainly due to dysfunction of the rectal sphincter or damage to the innervated nerves. Stool retention is a condition in which the patient has difficulty passing stool, also due to impaired nerve function. Clinically, it is usually seen mainly in lesions of the spinal cord, commonly acute myelitis and spinal cord compression; it can also occur in patients with advanced subacute joint degeneration of the spinal cord. Also seen in spinal cord injuries if the patient has cerebrovascular disease, such as massive cerebral infarction, and massive cerebral hemorrhage can also be caused; in addition, it is also seen in patients with infectious diseases of the central nervous system, including encephalitis and meningitis, mainly in patients with severe disease; if the patient is in advanced stages of dementia, the above conditions may also occur.
