Neurogenic bladder

[Kai]

Neurogenic bladder is lack of bladder control because of a nerve problem such as a stroke, spinal cord injury, or tumor.

Uncontrollable loss of urine (urinary incontinence) is the primary symptom.
Bladder catheterization, imaging, and tests to measure urine flow are done.
Treatment is aimed at periodic emptying of the bladder (for example, by intermittent catheterization and/or drugs).

Several muscles and nerves must work together for the body to control urination.
Neurogenic bladder may be

Flaccid: A flaccid bladder does not contract and the bladder fills up until it overflows. Then urine dribbles out.
Spastic: The person has involuntary bladder contractions and feels the need to urinate even when there is little or no urine in the bladder. Bladder contractions are typically poorly coordinated with the muscle that closes the opening of the bladder (urinary sphincter).
Mixed: Some people have elements of both flaccid and spastic bladder.

Any condition that damages or interferes with nerves that control the bladder or the bladder outlet can cause neurogenic bladder.
Common causes include stroke, spinal cord damage or injury, amyotrophic lateral sclerosis (ALS), Parkinson disease, multiple sclerosis, diabetic neuropathy, and nerve damage caused by pelvic surgery.
