Urethral structure is the abnormal narrowing of the urethra ( tube that releases urine from the body).
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
external pressure from an
enlarging tumor near the urethra, although this is rare.
Risk Factors Increased risk is associated with men who have a history of sexually transmitted disease (STD), repeated episodes
of urethritis or benign
prostatic hyperplasia (BPH). There is also an increased risk of urethral stricture after an injury or trauma to the pelvic
region. Any instrument
inserted into the urethra ( catheter or cystoscope) increases the chance of developing urethral structures.
