title: [Age-related characteristics of the functional state of kidneys (radiorenography data)].
abstract: Renal function of 91 healthy subjects aged 18-91 has been evaluated at radionuclide renography with the use of 131I-Hippuran. Renal excretory function, effective renal plasma and blood flows were found to decrease annually by 0.09 ml/kg in ageing men and by 0.08 ml/kg in women. The use of new indices may be useful for evaluation of renal blood circulation, especially during hypo- or hypervolaemia is proposed. These are the index of renal circulation efficiency and the mean time of circulating blood volume transfer through renal blood vessels.
