Urethral stricture

Definition:

An abnormal narrowing of the urethra.

Causes, incidence, and risk factors:

Urethral stricture may be caused by inflammation or scar tissue resulting from urethral or prostate surgery, disease or injury. It may also be caused by external pressure from an enlarging tumor near the urethra although this condition is rare. Increased risk is associated with men who have a history of sexually transmitted disease, repeated episodes of urethritis, or benign prostatic hyperplasia. There is also increased risk of urethral stricture after an injury or trauma to pelvic region.

Congenital (present at birth) pediatric strictures are rare, as are true strictures in women.
