[Morphologic changes in tubulo-interstitial diseases of the kidney].

Morphological changes providing basis for the diagnosis of certain tubular-interstitial diseases of kidney are surveyed in this paper. Different cylinders in tubular lumen, changes of tubular epithelium of endocytotic and of other origin and inflammatory cell reactions of interstice should be considered light microscopically. Immune histological examination of tubular basal membrane is essential for proper diagnosis.
