What is the definition of Meatal Stenosis?

Meatal stenosis is a narrowing of the opening of the urethra, the tube through which urine leaves the body.

What are the alternative names for Meatal Stenosis?

Urethral meatal stenosis

What are the causes for Meatal Stenosis?

Meatal stenosis can affect both males and females. It is more common in males.

In males, it is often caused by swelling and irritation (inflammation). In most cases, this problem occurs in newborns after circumcision. Abnormal scar tissue can grow across the opening of the urethra, causing it to narrow. The problem may not be detected until the child is toilet trained.

In adult men, the condition can result from surgery on the urethra, ongoing use of an indwelling catheter, or procedure to treat an enlarged prostate gland (BPH).

In females, this condition is present at birth (congenital). Less commonly, meatal stenosis may also affect adult women.

Risks include:

  • Having many endoscopic procedures (cystoscopy)
  • Severe, long-term atrophic vaginitis

What are the symptoms for Meatal Stenosis?

Symptoms include:

  • Abnormal strength and direction of urine stream
  • Bed wetting
  • Bleeding (hematuria) at end of urination
  • Discomfort with urination or straining with urination
  • Incontinence (day or night)
  • Visible narrow opening in boys

What are the current treatments for Meatal Stenosis?

In females, meatal stenosis is most often treated in the provider's office. This is done using local anesthesia to numb the area. Then the opening of the urethra is widened (dilated) with special instruments.

In boys, a minor outpatient surgery called meatoplasty is the treatment of choice. Dilation of the meatus may also be appropriate in some cases.

What is the outlook (prognosis) for Meatal Stenosis?

Most people will urinate normally after treatment.

What are the possible complications for Meatal Stenosis?

Complications may include:

  • Abnormal urine stream
  • Blood in the urine
  • Frequent urination
  • Painful urination
  • Urinary incontinence
  • Urinary tract infections
  • Damage to bladder or kidney function in severe cases

When should I contact a medical professional for Meatal Stenosis?

Call your provider if your child has symptoms of this disorder.

How do I prevent Meatal Stenosis?

If your baby boy has recently been circumcised, try to keep the diaper clean and dry. Avoid exposing the newly circumcised penis to any irritants. They may cause inflammation and narrowing of the opening.
