Impaired function of the brain, spinal cord or peripheral nerves can lead to neurogenic bladder. If the peripheral nerves going to the bladder are damaged, the bladder may become flaccid and distended. It cannot contract normally. As it fills, overflow incontinence may develop. The large volume of trapped urine can lead to infections. If the spinal cord or brain is injured, reflexes to the bladder may become heightened. This can lead to unexpected contractions of the bladder and incontinence. The bladder may be only able to hold small amounts of urine. Neurogenic bladder can occur at any age, but is more common in the elderly.
Causes of Neurogenic Bladder
Diseases that affect the function of the brain can lead to neurogenic bladder. These include brain tumors, stroke, multiple sclerosis, amyotrophic lateral sclerosis, hydrocephalus and Alzheimer's disease. Disorders that involve the spinal cord, such as spinal cord tumors, spinal cord injuries, spinal stenosis and herniated discs, can also lead to the development of neurogenic bladder. Diabetes, chronic alcohol use, abdominal or pelvic surgery, trauma or tumors, can lead to neurogenic bladder.
Signs and Symptoms of Neurogenic Bladder
Urinary incontinence is one of the hallmarks of neurogenic bladder. It can either be varcharacterized by the uncontrolled release of large volumes of urine or by continuous dribbling of small amounts of urine. Other common symptoms include a continuous urge to urinate and the sensation that the bladder is full, even after voiding. Painful, burning urination can occur, especially is infections occurs.
