title: Anterior urethral valve presenting in an adult male.
abstract: Anterior urethral valves are a rare congenital anomaly which can occur singly or in combination with a proximal urethral diverticulum. A retrograde urethrogram and voiding cystourethrogram can easily make the diagnosis unless the valve is located with the glandular urethra. Cystoscopic examination of the urethra can overlook anterior urethral valves, but by altering the flow of the irrigant, the cystoscope can be used to make these valves very apparent.
