urethral stricture
Narrowing of the urethral lumen due to scar tissue formation, causing obstructive voiding symptoms in pediatric patients.
Full Definition
A pathological narrowing of the urethral lumen resulting from scar tissue or fibrosis within the urethral wall or surrounding corpus spongiosum. In pediatric patients, strictures may be congenital or acquired following trauma, infection, instrumentation, or previous urological procedures. Clinical presentation includes decreased urinary stream, straining to void, incomplete bladder emptying, and recurrent urinary tract infections. Diagnosis is confirmed through retrograde urethrography or voiding studies. Treatment options range from urethral dilation to formal urethroplasty depending on stricture length, location, and etiology.
Usage
Usage note: Specify location (anterior vs posterior, bulbar vs penile) when known for precise documentation.
