Obstetric care begins with determining gestational age, which has the least variability in early pregnancy. This current study was planned to provide an overview of fetal kidney length and volume as a useful adjunct parameter for better determination of gestational age.
MATERIALS AND METHODS
Normal singleton pregnancies from 18–40 weeks of gestational age, referred to the department of Radio-diagnosis and Imaging at VIMS & RC, Bangalore. Fill PC-PNDT [Prenatal Diagnostic Technique] form i.e Obstetric ultrasonography were performed using Affinity 50 G pro ultrasound scanner using a 3.5 MHz convex probe. Images were recorded in the system as DICOM.
Out of 200 patients who presented themselves for routine obstetric ultrasound scan within the period of study, 150 patients met the inclusion criteria [18th week of gestation to term] and were selected for the study while patients were excluded from the study for the following reasons; for not remembering their LMP, fetus with IUGR, 10 patients presented with oligohydramnios, poly-cystic renal dilated renal pelvis. It correlates strongly with gestational age while the relationships between right and left kidney lengths with gestational age were established. However no correlation of gestational age with volume. Fetal kidney length increases with increase in FGA and shows excellent intra and inters class correlation coefficient which suggests good agreement and reproducibility of measurements.
