[Urography and the isotopic renogram under diuresis enhance the diagnosis and the indication for therapy in congenital hydronephrosis].

Abstract

Analysis of a group of 276 patients with congenital hydronephrosis by dysfunction of pyeloureteral function shows that in the most cases the diagnosis has to be established by corroborating the data given by urography, echography, and isotopic renogram. In the cases of controversial hydronephrosis diagnostic, urography and renogram under diuresis induction are very important in practice.
