Urinary and fecal incontinence occurs mainly because of problems with the innervation. The first thing that presents is the spinal nerve, which can be caused by, for example, trauma, tumors, and bleeding secondary to tumors. The most common cause is injury to the spine due to trauma, which in turn leads to nerve damage. The main manifestation is motor-sensory impairment below the plane of injury, and vertebral CT and MRI can clarify the extent and location of the injury. Secondly, occupying lesions in the spinal canal, the aggravation of occupying lesions is a gradual process, and incontinence is not likely to appear suddenly. When a degree of occupying lesion generation or secondary bleeding occurs, incontinence may occur within a short period of time. The approximate site of the lesion is determined by the plane of sensory-motor disturbance in the patient, and an appropriate MRI examination can detect the lesion. Whether the incontinence is caused by a traumatic vertebral fracture or a possessive lesion, surgical treatment is indicated.
