Urge incontinence
is basically a storage problem in which the bladder muscle contracts
inappropriately. Often these contractions occur regardless of
the amount of urine that is in the bladder. Urge incontinence
may result from neurological injuries (such as spinal cord injury
or stroke), neurological diseases (such as multiple sclerosis),
infection, bladder cancer, bladder stones, bladder inflammation,
or bladder outlet obstruction (enlarged prostate). However, the
majority of cases are classified as idiopathic--a specific cause
cannot be identified.
