[Obstruction caused by anterior urethral valves in childhood]

Presentation of 3 patients (aged 11 years, 9 months and 9 years old) with diaphragm-like valves in the anterior urethra. Haematuria, urinary tract infection and thin voiding stream were the most common symptoms. Transurethral endoscopic resection with cold blade solved the problem appropriately in two cases, though the youngest patient required resection of stenotic area and end-terminal by-pass of the urethra.
