“…Moreover, it does not generate the effects of aliasing and color maps are independent of the angle of insonation. The 3-DPD not only allows a full and adequate study of the vascular placental tree by identifying the different branches of villi [ 18, 19 ] but also produces a quantitative assessment of the number of vessels through the vasculature and blood flow index, by applying flow rates and vascularization. By the 3D method, vascular villi of the first, second, and the third order can be seen and thus a higher percentage is achieved in comparison with 2D Doppler technique.…”

The goal of this study was to investigate the fetal renal vascularization during the third trimester of gestation and the perinatal outcome in pregnancies diagnosed with hypertension. Depending on the medical history, the cases were divided into two groups: chronic hypertension (CHT) group and gestational hypertension (GHT) group. The vascularization and the volume of kidneys were observed in prenatal period by three-dimensional ultrasound. We monitored gestations and perinatal complications. Renal volume and vascularization were detected in 45 cases complicated by GHT and 21 cases with CHT during the 20-month study period. The alteration in fetal renal volume and vascularization may be an in utero cause of subsequent intrauterine and neonatal complications, such as cesarean section because of fetal distress (36%), perinatal infection (24%), treatment in neonatal intensive care unit (39%), or increased perinatal mortality (1%) in affected cases. The results demonstrate that fetuses with depressed vascularization of medullae had 1.5 times the risk of an abnormal outcome compared with the control group. The volume of kidneys had a strong correlation with their vascularization. Detailed ultrasound examinations of renal parenchyma appear to be useful for the prenatal diagnosis of intrauterine hypoxia, allowing the detection of potential pathological fetal conditions in utero.

“…Fetal-downregulated vascularization had influence on fetal renal development [ 18, 20 ]. This is an important conclusion, because it suggests that early identification of women at low risk of HPD can be improved to obtain prophylactic treatment and intense surveillance can be initiated at appropriate time.…”

Early prenatal diagnostics and the importance of genetic counseling are of great interest for echosonographic evaluation of normal fetus anatomy. Development of the human fetal kidney runs through a series of continual and mutually dependent changes during which the kidney obtains its morphological and functional maturity. This study was created to estimate the changes in kidney size during gestation in fetuses from the 4th to the 10th lunar month, to evaluate the dynamics of their growth, as well as to establish the validity of the volume calculated from these dimensions. Serial measurements of kidney dimensions (length, width, thickness) were performed in 110 fetuses. Photomicrographs of kidneys from the 4th, 6th, 8th and 10th lunar months are also presented. On the basis of the results obtained by our examination, we concluded that the period from the 14th to 16th week of intrauterine life is the fastest period of kidney growth during fetal development. Using the ellipsoid formula for calculating the fetal renal volume offers an underestimation of about 32–33% on average. The importance of this study lies in determining the average fetal kidney dimensions, which could be used as standard values in obstetrics.
