Renal blood flow in acute epidemic nephritis (nephropathia epidemica of Scandinavia).
Different haemodynamic and functional parameters were studied in 5 cases of acute epidemic nephritis with uraemia using nephroangiography and dye-dilution measurements combined with determination of extraction ratio and clearance for 51Cr-EDTA and PAH. In the acute phase, with greatly reduced renal function, increased vascular resistance was noted in spite of the vasodilatation observed in the renal artery out to and including the interlobular arteries. Moreover, angiography revealed enlarged kidneys with an increase in the thickness of the cortex and reduced cortical contrast accumulation. The renal blood flow, which was normal or slightly reduced initially, increased during convalescence, and renal function returned to normal. The investigation indicated that a primary vascular lesion in glomerular to postglomerular capillaries gives rise to pronounced interstitial oedema, which, probably as a result of secondary tubular compression, may be the cause of the rapidly developing renal failure.
