[Valves of the posterior urethra: case reviews].
13 male patients, with type-I Young urethral valves are reported. We analyze the most significant clinical, analytical and radiological findings of them all, at the diagnosis and during the evolution. The clinical course has been from 6 month up to 5 years, the average time being of 3 years, 3 of them have evolved towards a renal insufficiency. The patients diagnosed at the neonatal period (5 in our series) have a higher degree of obstruction producing a greater clinical and radiological alteration at the moment of the diagnosis and a worse prognosis in spite of early disobstructive measures.
