Objective: Studying the relation between fetal renal blood flow and fetal renal volume in women with growth restricted fetuses. Materials and methods: This observational study included a total of 40 women, divided into two groups: Group A: including patients with intrauterine growth retardation (20 females). Group B:including patients with normal pregnancy (20 females). The study was carried out in Special Care Centre for the fetus in Ain Shams University Maternity Hospital.2DUS & 3DUS were performed with a 3.5-5 MHZ abdominal probe. Prenatal Doppler ultrasound examination was performed using Voluson E6 (GE). Difference between the two groups was analyzed using independent student’s t-test [for numeric variables]. Association between two metric variables was estimated using the Pearson’s correlation coefficient. Significance level was set at 0.05. Results: The current study showed that the mean values of UA PI, UA RI, renal artery RI and renal artery PI were significantly higher, while the mean value of MCA-RI was significantly lower in women of group I when compared to those of women of group II. The right renal volume, left renal volume and combined renal volume in included women were significantly lower in women of group I when compared to those of women of group II. Conclusions: In conclusion, the current study showed that intrauterine fetal growth restriction due to placental insufficiency seems to be associated with significantly lower fetal renal blood flow and significantly smaller renal volumes, when compared to normally-grown fetuses.
