[Valves of the anterior urethra without diverticulum. Description of 3 cases]

Anterior urethral valves are rare entities, especially in case they are not associated to urethral diverticulum. Because of their obstructive effects on the urinary tract, they must be searched in case of clinical evidence of lower obstructive uropathy. Three cases of anterior urethral valves without urethral diverticulum are herein reported. Differential diagnosis with urethral diverticula, endoscopic features and treatment are discussed and emphasized.
