This article presents the results of the surgical treatment of the posterior urethral valves (PUV) in 58 children (between 2 months and 15 years of age), between 1998 and 2009. In all, 26 patients were treated using the endoscopic method (EM) and 32 patients were treated by the proposed method, using a metallic urethrotome (MU). Diagnosis of the urethral valves was done using ultrasonography, voiding cystourethrogram, urethrocystoscopy, uroflowmetry and cystomanometry. Mathematical modeling was applied to assess the treatment methods. The proposed method, using the metallic urethrotome, was preferable to the endoscopic method.
