title: [Correspondence of functional and structural findings in tubulo-interstitial disorders in chronic glomerulonephritis].
abstract: In 237 patients with chronic glomerulonephritis and according to the serum creatinine level of functional compensation tubular and tubulointerstitial renal functions, respectively, were investigated and compared with the light-microscopic findings of the renal interstice. A distinct structural tubulointerstitial lesion (tiK) was found in 30%. The diagnostic predictivity for the recognition and the exclusion of the tiK was tested for single or paired data of the renal function. As a result it is possible with a suitable combination of parameters in on an average more than 80% of the cases to establish or to exclude function-diagnostically a tubulointerstitial structural lesion even in still inconspicuous creatinine values. From the clinical point of view thus the information value of functional diagnostic investigations of the renal water treatment is confirmed (concentration power, dilution ability, water diuresis), in which case the differentiated test of the renal acidification may supplement the informations about the tiK-situation.
