IUGR affects 3-5 percent of the pregnancies, and is linked to poor perinatal outcomes. As per obstetric surveillance, Doppler ultrasound is a fairly common procedure which has paid much attention to umbilical and cerebral arteries, and has not been thoroughly studied as far as fetal renal hemodynamics is concerned. The long-term goal of our study was to test the Doppler parameters of fetal renal arteries (pulsatility index (PI), resistance index (RI), peak systolic velocity (PSV) in normal and IUGR pregnancy as an extension of our previous attempts to make clinical use of the results of our Doppler studies to infer fetal compromise. Based on the prospective observational style of study, the Doppler studies were conducted at given gestational ages and followed a standardized set of protocols in order to ensure reproducibility and accuracy. We identified PI and RI measurements higher in PI with IUGR pregnancies signifying that you have an elevated resistance and bad perfusion. Convalues were also reduced considerably which pointed to poor renal blood flow. We were not alone in finding evidence that, abnormal renal artery Doppler indices were early warning signs of placental insufficiency and poor perinatal outcome. Our findings are that fetal renal artery Doppler study and disruptive information may help in the methods of diagnosis and autonomous practice, further, this study should be incorporated into routine practice in order to be able to assess risks, timing of optimal intervention and perinatal results. We emphasize the need to have standardized protocols with clear and specific measures, and potential future studies, using larger sample sizes, to answer clinical significance and long term consequences.
