Meatal stenosis

Definition

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

Alternative Names

Urethral meatal stenosis

Causes

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) after a newborn is circumcised. This leads to abnormal tissue growth and scarring across the opening of the urethra. In most cases, the problem is not found until the child is toilet trained. Surgery on the urethra, chronic catheterization, or other medical instruments in the urethra may also lead to meatal stenosis.

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

Risks include:

Symptoms

Symptoms include:

Exams and Tests

In boys, a history and physical exam are enough to make the diagnosis.

In girls, a voiding cystourethrogram may be done. The narrowing may also be found during a physical exam, or when a health care provider tries to place a Foley catheter.

Other tests may include:

Treatment

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.

Outlook (Prognosis)

Most people will urinate normally after treatment.

Possible Complications

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 to Contact a Medical Professional

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

Prevention

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.
