title: [Posterior urethral valve--etiology, diagnosis and treatment].
abstract: The problems concerned the etiology, diagnosis treatment of the posterior urethral valves (PUV) were described. The malformation is found in boys and creates multi-infra cystic barrier symptoms during miction. USG examination is very helpful in the diagnosis of PUV, as well as micturating cysto-urethrography and urodynamic examination. In differential diagnosis of PUV, one must take into account the barrier causes in the following portions of the urinary tract: narrowing of the urethral exit anterior urethral valves, polyps, diverticuli, hypertrophy of the seminal cumulus. Surgical treatment includes valvular electro-resection, laser destruction, widening by the use of Fogarty catheter and Foley catheter ended with a NaCl solution filled balloon.
