Anatomical incontinence is the involuntary release of urine related to structural problems of the urinary tract that affect the urine flow. Anatomical incontinence may be present from birth (congenital).

The main symptom of anatomical incontinence is an almost continual release of urine.

Anatomical incontinence is caused by structural problems in the urinary tract that allow urine to leak past the muscle (sphincter) that retains urine in the bladder. These problems include:

• An abnormal passage (fistula) leading from the urethra to another organ of the body.
• An abnormal pouch (diverticulum) in the wall of the urethra. Urine can become trapped in the pouch and then leak out.
• An abnormal opening between the bladder and vagina (vesicovaginal fistula) or between a ureter and the vagina (ureterovaginal fistula).

Treatment of anatomical incontinence concentrates on correcting the structural problem that is interfering with the bladder's retention of urine.
