Answer

Answer

If a problem occurs within the nervous system, the entire voiding cycle is affected. Any part of the nervous system may be affected, including the brain, pons, spinal cord, sacral cord, and peripheral nerves. A dysfunctional voiding condition results in different symptoms, ranging from acute urinary retention to an overactive bladder or to a combination of both.

Urinary incontinence results from a dysfunction of the bladder, the sphincter, or both. Overactive bladder is associated with the symptoms of urge incontinence, while sphincter underactivity (decreased resistance) results in symptomatic stress incontinence. A combination of detrusor overactivity and sphincter underactivity may result in mixed symptoms.
