Causes, incidence, and risk factors
Meatal stenosis can affect both males and females, but it is more common in males. In males, it is often caused by inflammation following the circumcision of a newborn. This leads to abnormal tissue growth and scarring across the urethral opening. The problem is usually not detected until the child is toilet trained.
- Abnormal strength and direction of urinary stream
- Visible narrow opening at the meatus in boys
- Discomfort with urination (dysuria and frequency)
- Incontinence (day or night)
- Bleeding (hematuria) at end of urination
- Urinary tract infections
Signs and tests
In boys, history and physical exam is adequate to make the diagnosis. In girls, VCUG (voiding cystourethrogram ) is usually diagnostic. Other tests may include:
In females, meatal stenosis can usually be treated in the physician's office using local anesthesia to numb the area and dilating (widening) the urethral opening with special instruments. In boys, meatoplasty , a minor outpatient surgical procedure, is the treatment of choice.
Most people can expect normal urination after treatment.
Persistent urinary problems including abnormal stream, painful urination, frequent urination, urinary incontinence, blood in the urine, and increased susceptibility to urinary tract infections can be complications.
In a recently circumcised male infant, try to maintain a clean, dry diaper and avoid any exposure of the newly circumcized penis to irrititants.
