About
Narrowing of the tube that carries urine out of the body (urethra) can be caused by the buildup of scar tissue due to:
- Trauma or direct injury to the urethra or pelvis (pelvic fracture)
- Intermittent or long-term use of a catheter, a tube inserted through the urethra to drain the bladder
- Enlarged prostate or previous surgery to remove or reduce an enlarged prostate gland
- Cancer of the urethra or prostate
- Sexually transmitted infections
Stricture is more common in males than females because of the longer urethra.
Signs and symptoms of urethral stricture include:
- Slowing of your urine stream, which can happen suddenly or gradually
- Urine leakage or dribbling after urination
- Difficulty, straining or pain when urinating
- Increased urge to urinate or more frequent urination
- Swollen penis
- Blood or discharge from the penis
- Pain in the pelvis or lower abdomen
