What causes stress and urge incontinence?
An anatomical (structural) cause is the most common reason for stress incontinence whereas urge incontinence suggests that the bladder muscle is contracting excessively (detrusor instability) at an inappropriate time. This is also called an unstable bladder. These causes and effects are by no means mutually exclusive: A woman presenting with symptoms of stress incontinence may prove to have detrusor instability and urge incontinence could be related to inadequate support to the bladder outlet.
