Nierendurchblutung, Diurese und Isotopennephrogramm bei experimenteller Stenosierung der Nierenarterie

Abstract

After experimental stenosis of the renal artery of the dog, the isotope nephrogram shows a prolongation of the transit-time, when the renal blood flow is reduced to 40--70%. This finding was most significant in low diuresis (0,05--0,2 ml/min), sporadic in moderate diuresis (0,2--2,0 ml/min), no longer demonstrable in forced diuresis (greater than 2,0 ml/min). The diuretic effect of X-ray contrast medium (70% Na-Meglumin-Jotalamat, 0,5 ml/kg i.v.) normalizes a pathologic ING in low diuresis.
