Anterior urethral valves.

ABSTRACT

Posterior urethral valves (PUV) are the most frequent cause of obstructive uropathy in boys. Rarer causes of obstructive uropathy include bladder diverticulae, meatal stenosis and urethral or bladder stones. Anterior urethral valves are rare causes of urinary obstruction in boys and are ten times less frequent than PUV in the literature(1-6). This paper highlights our experience with 5 patients with anterior urethral valves.
