Infravesical obstruction in a young boy. (Anterior urethral valve with diverticulum)

The reason of the obstructive voiding abnormalities in children may be functional or mechanical. We report an anterior urethral valve associated with a wide mouthed congenital urethral diverticulum in a child. The flap-like distal margin which acts as an obstructing valve and the proximal margin of the diverticulum were incised endoscopically with electrocautery in the midline. He was voiding well in the eight-month followup period. Especially in children with voiding dysfunction, anterior urethra must be examined carefully to prevent misdiagnosis of the recognizable lesions
