Relation of the Renal Artery Color Doppler With the Umbilical Artery and Amniotic Fluid Index in Fetuses Affected by Intrauterine Growth Retardation

Objectives: This study was performed to investigate the relationship between the renal artery color Doppler with the umbilical artery and amniotic fluid index (AFI) in fetuses affected by intrauterine growth retardation (IUGR). Materials and Methods: This was a descriptive cross-sectional diagnostic study and the target population included pregnant mothers who were diagnosed to have fetuses with IUGR referring to the Al-Zahra treatment center in Tabriz. At least 40 samples were referred between October 2019 and May 2020. The patients were evaluated using the transabdominal ultrasound of the umbilical artery and fetal renal artery, and then using the color Doppler values of the umbilical artery and fetal renal artery. Results: The present research was performed on 40 pregnant females with an IUGR fetus with umbilical artery percentile upper that 95% whose minimum to maximum age range was 22-38 years. There is no relationship between umbilical artery and renal artery color Doppler. In addition, umbilical artery color Doppler is not related to amniotic fluid, also renal artery color Doppler demonstrated no significant correlation with amniotic fluid index. Conclusions: Based on our results, the PI of the umbilical artery had no significant correlation with that of the renal artery. In addition, there was no significant correlation with the PI of the renal artery and AFI.
