The object of the study was to investigate the outcome in newborns with growth retardation who were diagnosed with fetal renal hyperechogenicity without anatomical abnormality during any stage of pregnancy. Depending on the fetal renal ultrasound result, the cases were selected into two study groups. There was an intrauterine growth retarded group with fetal renal medullary hyperechogenicity and another one without fetal renal medullary hyperechogenicity. There was a comparison of the two study groups of prenatally diagnosed intrauterine growth retardation cases with or without renal medullary hyperechogenicity. Renal parenchyma were observed after birth as well, within the first five days after birth and several times until the 14th postpartum day in positive cases. Hyperechogenic renal medullae were detected in 22 out of 85 cases with intrauterine growth retardation during the 8 month long study period. This may be an in utero cause of subsequent intrauterine and neonatal complications, such as cesarean section because of fetal distress (32%), perinatal infection (27%), treatment in a neonatal intensive care unit (60%) or increased perinatal mortality (9%). The results demonstrate that fetuses with hyperechoic medullae had 1.5 times risk of an abnormal outcome as compared with fetuses with normal echoic kidneys in intrauterine growth retardation. Detailed ultrasound examinations of renal parenchyma appear to be useful methods in the prenatal diagnosis of intrauterine hypoxia to detect possible pathological fetal condition in utero.
