Urinary incontinence (fecal incontinence) is a common and debilitating end result of a number of diseases that affect quality of life and lead to disability, morbidity, and increased burden on society. Given the diverse causes of fecal incontinence, it is important to evaluate and identify the underlying pathophysiological mechanisms.

Fecal incontinence is defined as the involuntary passage of rectal contents (solid or liquid stool) through the anal canal and the inability to delay evacuation until socially convenient.
