title: [Persistent tubular Nephrogram in a newborn (author's transl)].
abstract: The case presented is that of a newborn with palpable renal masses and oliguria that lasted for the first five days of live. The pyelography that was perfomed showed a prolonged tubular nephrogram and a light increase in kidney size. The good general state, normal test results, a kidney biopsy which failed to show any histological changes and its favorable development, suggested a diagnosis of transitory tubular obstruction caused by protein casts. It is suggested the diagnosis of the Tamm Horsfall proteinuria in the light of the works published in which similar case histories and urograms were cited. These works proved the presence of Tamm Horsfall mucoprotein by the use of specific immunofluorescence tests.
