  • Title: [Micromorphological and functional alterations of the kidney during persistent ureteral obstruction (author's transl)].
    Author: Hartung R, Schmeller M, Mauermayer W, Blümel G.
    Journal: Urologe A; 1980 Jan; 19(1):11-22. PubMed ID: 7355523.
    Abstract:
    Alterations on the upper urinary-tract and on the kidney have been investigated by histology and scanning-electron-microscopy (SEM) in an animal study on the rat. Examinations have been performed 7, 14, 28 and 56 days after double-ligating the ureter. The documentation shows the developed alterations which are remarkable in the area of the papilla and medulla of the kidney, whereas the glomerula are nearly unchanged in comparison with the controls. At the same time function-tests with radioactively labelled Jodium-Hippuran and technetium-DTPA have been performed. The nephrograms in the region of interest technique showed after 14 days isosthenuria and after 4 weeks no signs of any function on the operated side.
