The most common site of posterior urethral valve is that in which there is an exaggeration of the normal ridges which extend from the midline dorsal urethral ridge and from the verumontanum to surround the urethra just before the membranous region. Obstruction to urine flow may be complete or partial. In patients with partial obstruction, failure to thrive, systemic acidosis with renal failure and continuous over-flow dribbling rather than a good urinary stream may be seen. Apart from the problem of renal damage consequent to the obstruction, these children are subject to recurrent urinary infections. Excretory urography and retrograde cystourethrography are needed to establish the diagnosis. The characteristic proximal ballooning of the urethra is best seen during micturition or attempts to express urine from the bladder. Early surgical decompression is warranted. A temporary diversionary procedure is recommended, with a definitive operation at a later age to correct the valvular obstruction. We experienced a case of posterior urethral valve which was developed in a 4 years old boy, treated this case by destruction of posterior urethral valve and report it with brief review of literatures.
