Neurogenic bladder occurs when nerve damage from a spinal cord injury disrupts the communication between the brain and the bladder, preventing normal voluntary control over urination. Depending on the level and severity of the spinal cord injury, victims may experience either an overactive bladder (spastic bladder) that empties involuntarily, or an underactive bladder (flaccid bladder) that fails to empty completely. Both conditions require intensive medical management to prevent dangerous complications such as urinary tract infections, kidney damage, bladder stones, and autonomic dysreflexia.
Neurogenic bowel dysfunction similarly results from interrupted nerve signals between the brain and the intestines, causing loss of voluntary bowel control. Victims may experience chronic constipation, fecal incontinence, or a combination of both, requiring daily bowel management programs that can take hours to complete. The psychological and emotional toll of losing control over these basic bodily functions cannot be overstated, often leading to depression, social isolation, and diminished quality of life.
The severity of neurogenic bladder and bowel dysfunction typically correlates with the level of spinal cord injury. Cervical and high thoracic injuries often result in spastic or reflex bladder and bowel, while lower thoracic and lumbar injuries may cause flaccid or areflexic dysfunction. Understanding the specific type and severity of dysfunction is critical for developing an appropriate management plan and calculating the full extent of future medical needs in a catastrophic injury claim.
