Centile Charts of Fetal Kidney and Adrenal Gland Length: A Prospective Study in Indian Population in the State of Bihar

Abstract

Normal development of the fetal kidneys and adrenal glands is essential for a good crucial neonatal outcome. There is, however, paucity of data on normal fetal adrenal gland and renal length in populations of North India and this poses a not infrequent dilemma when an anomaly is suspected during the anomaly scan. The objective of this study was to obtain gestation wise data of fetal renal length and adrenal length for 18, 19, 20 and 21 weeks of gestation and construct a gestation age wise size chart. This was a cross sectional study of 128 consecutive normal pregnancies after exclusion of multiple gestations, maternal complications, congenital anomalies and a family history of congenial adrenal hyperplasia. Gestational age of the fetus was calculated from fetal biometry. Measurements were made in the sagittal plane as length including renal and adrenal, longest pole to pole length of kidney and adrenal gland length calculated as the difference between the values. The values were analysed to yield the 95% confidence interval along with the 50th centile for gestational age groups of 18–21 weeks.
