Meatal stenosisUrethral meatal stenosis is a narrowing (stenosis) of the opening of the urethra, the tube through which urineleaves the body from the urinary bladder.
Causes, incidence, and risk factorsMeatal stenosis can affect both males and females, but it is more common in males. In males, it is often caused by inflammationfollowing the circumcisionof a newborn. This leads to abnormal tissue growth and scarringacross the urethral opening. The problem is usually not detected until the child is toilet trained. In females, this condition is a congenital(present from birth) abnormality which can cause urinary tract infectionsand bed-wetting (enuresis). Symptoms
Signs and testsIn boys, history and physical examis adequate to make the diagnosis. In girls, VCUG (voiding cystourethrogram) is usually diagnostic. Other tests may include:
TreatmentIn females, meatal stenosis can usually be treated in the physician's office using local anesthesiato 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. PrognosisMost people can expect normal urination after treatment. ComplicationsPersistent urinary problems including abnormal stream, painfulurination, frequent urination, urinary incontinence, blood in the urine, and increased susceptibility to urinary tract infections can be complications. PreventionIn a recently circumcised male infant, try to maintain a clean, dry diaper and avoid any exposure of the newly circumcized penis to irrititants. Source
