Definition of Urethral stricture
Urethral stricture is an abnormal narrowing of the tube that carries urine out of the body from the bladder (urethra).
Causes, incidence, and risk factors
Urethral stricture may be caused by inflammation or scar tissue from surgery, disease, or injury. It may also be caused by pressure from an enlarging tumor near the urethra, although this is rare.
Signs and tests
A physical examination may show the following:
The urethra may be widened (dilated) during cystoscopy by inserting a thin instrument to stretch the urethra while you are under local anesthesia. You may be able to treat your stricture by learning to dilate the urethra at home.
Treatment usually results in an excellent outcome. However, repeated therapies may be needed to remove the scar tissue.
