[Incidence and early detection of glomerulonephritis]

Within of a for the first time performed aimed study of the early recognition and frequency of the glomerulonephritis in 1,425 males the findings of an "asymptomatic proteinuria" were proved in 5.26% of the affected persons. As a result of a comprehensive investigation, the close of which was in every case the biopsy of the kidney with the histological examination of the renipuncture cylinder, a frequency of glomerulonephritis of 2.8% was found. Within this investigation the findings of an "asymptomatic proteinuria" proved to be the decisive parameter independent of the size of excretion and the reproducibility. The serological investigations did not show any specifity and proved to be insignificant for the early recognition. The results confirm that the diagnosis of "physiological proteinuria" may be made only then when there is an inconspicuous histological finding. In lacking renal histology every form of the proteinuria should at first be attributed to glomerular process.
