Anterior urethra valves
Anterior urethral valves (AUVs) are rare congenital abnormalities causing mild to severe obstruction in children and possibly associated with a proximal diverticulum. Anterior urethral valves are located along the anterior urethra: 40% at the bulbar urethra, 30% at the penoscrotal junction, and 30% in the pendulous urethra. Anterior urethral valves are diagnosed by VCUG which demonstrates a dilated urethra proximal to the valve and narrowing distally.
