This study used color Doppler imaging to establish the normal values of the pulsatility index in the fetal renal arteries in a group of 304 uncomplicated singleton pregnancies. The measurements were taken between 26 and 42 weeks of gestation. The median was 2.79 (95% confidence interval: 2.72–2.86) for 26 weeks' gestation, and it then fell linearly to 1.96 (95% confidence interval: 1.92–2.00) at 40 weeks. Compared with values published so far in the literature, the range was clearly smaller. These normal values could be used as a basis for further investigations on these vessels.
