Using duplex Doppler ultrasonography in asymmetrically grown fetuses with
decreased amniotic fluid, we found the renal artery waveform pattern was
different from that in the normally grown fetus. Such an abnormal waveform
may reflect an increase in vascular resistance within the renal bed in
oligohydramnios and intrauterine growth retardation. This would suggest that
local mechanisms are operational and may influence renal blood flow in the
human fetus with intrauterine growth retardation.
