Urethral stricture

A urethral stricture, also known as urethral narrowing, is a constriction of the urethra that obstructs normal urine flow. This condition can be caused by scar tissue that forms in the urethra following an injury, infection, or due to other medical procedures. Urethral strictures affect men more often than women due to the longer urethra in men.

Causes of urethral stricture

  • Injuries to the urethra from catheters or surgical procedures
  • Chronic urinary tract infections or sexually transmitted diseases
  • Trauma in the pelvic area
  • Repeated inflammations of the urethra (urethritis)

Symptoms of urethral stricture

  • Weak or interrupted urine stream
  • Difficulty urinating
  • Pain during urination
  • Sensation of incomplete bladder emptying
  • Frequent urinary tract infections

Diagnosis of urethral stricture

The diagnosis of a urethral stricture is made through a combination of medical history, physical examination, and diagnostic tests. Uroflowmetry, a urine flow measurement, is used to assess the strength of the urine stream. In some cases, a cystoscopy is performed to examine the urethra and bladder. A retrograde urethrography with contrast medium helps determine the exact location of the narrowing.

Treatment options for urethral stricture

  • Dilation: Mechanical widening of the urethra, used in mild cases, but may require repeated procedures
  • Endoscopic Urethrotomy: A surgical procedure to cut or remove the narrowed area of the urethra
  • Reconstructive Surgery: In severe cases, extensive reconstructive surgery may be necessary to permanently resolve the narrowed area

Preventive measures for urethral stricture

To reduce the risk of a urethral stricture, it is important to exercise caution during medical procedures such as catheterizations. Early and appropriate treatment of urinary tract infections can also help minimize the risk of a stricture.
