External Urethral Orifice Stricture is a condition where the opening of the urethra, the tube that carries urine from the bladder out of the body, becomes narrowed or constricted. This narrowing can cause problems with urination and can lead to various health complications. Below is a comprehensive and simple explanation of the condition, its causes, symptoms, treatments, and more.

The external urethral orifice stricture occurs when the external opening of the urethra becomes narrowed or blocked. The urethra is a tube-like structure that carries urine from the bladder to the outside of the body. When the opening at the external urethra is constricted, it can be difficult for urine to pass through, leading to various urinary symptoms and discomfort.


Pathophysiology (Structure, Blood, Nerve Supply)

  • Structure: The external urethral orifice is the opening of the urethra located at the tip of the penis in men and above the vaginal opening in women. It is a small, specialized opening designed for urine to exit the body.
  • Blood Supply: The blood supply to the external urethral orifice is primarily provided by branches of the internal iliac arteries. These branches ensure that the tissue around the urethra receives adequate oxygen and nutrients.
  • Nerve Supply: Nerves in the area come from the pudendal nerve, which controls the muscles of the pelvic floor and helps with urination. The sensory nerves also play a role in recognizing pain and discomfort if the urethral opening is affected by a stricture.

Types of External Urethral Stricture

  1. Congenital Stricture: This type is present from birth, usually due to abnormal development of the urethra.
  2. Acquired Stricture: This happens later in life and is most commonly caused by injury, infection, or inflammation.
  3. Primary Stricture: Strictures that develop without any underlying cause or previous injury.
  4. Secondary Stricture: These develop as a result of previous surgery, catheterization, or trauma.

Causes of External Urethral Orifice Stricture

  1. Trauma or Injury: Accidents or physical trauma to the urethra can cause scarring and narrowing.
  2. Infections: Chronic urinary tract infections (UTIs) can lead to inflammation and scarring.
  3. Sexually Transmitted Diseases (STDs): Diseases like gonorrhea and chlamydia can cause urethral damage.
  4. Previous Surgery: Surgical procedures around the pelvic area or urethra may cause scarring.
  5. Catheterization: Long-term use of a catheter can lead to urethral stricture.
  6. Inflammatory Diseases: Conditions like urethritis can lead to scar tissue formation.
  7. Radiation Therapy: Radiation treatment for pelvic cancers can damage the urethra.
  8. Genetic Disorders: Some individuals may be genetically predisposed to urethral strictures.
