title: [Flowmetry of the fetal renal artery--a possibility for improving the assessment of fetal circulatory centralization].
abstract: The use of flowmetry of the foetal renal artery offers a diagnostic improvement by analysing intrauterine centralisation of the foetal circulation. We used the examination results of 82 pregnant women, who were in intensive prenatal care, to check the prediction of foetal distress using the flowmetry of the renal artery. In foetuses showing an increased flow resistance of the aorta and a pathological flow of the renal artery, the rate of caesarian section, necessitated by foetal distress, was 63.6%. By the forming of quotients from the pulsatility indices of the internal carotid artery and the aorta on the one hand, and the renal artery and the internal carotid artery on the other hand, it seems to be possible to get information about the severity of the centralisation of the foetal circulation by existence of an intrauterine hypoxia. The rate of the operative delivery as a consequence of a foetal distress rises from 6.6% with normal PI quotients to 83.4% if both quotients are outside the double standard deviation.
