meatal stenosis
Pronunciation: mee-AY-tal sten-OH-sis
Narrowing of the urethral opening (meatus) causing a thin, deflected urinary stream and potential voiding difficulties.
Full Definition
A condition characterized by pathological narrowing of the external urethral opening, most commonly occurring as a complication of circumcision in male infants. The stenosis results from inflammatory scarring and may present with a thin, dorsally deflected urinary stream, straining to void, or incomplete bladder emptying. Clinical signs include a pinpoint meatus with surrounding fibrotic tissue. The condition is diagnosed clinically and may require surgical correction (meatotomy or meatoplasty) if symptomatic. Early recognition is important to prevent complications such as recurrent urinary tract infections or bladder dysfunction.
Usage
Usage note: Describe stream characteristics and distinguish from more proximal urethral strictures.
