Background: In routine ultrasonography, the ultrasonologist measures the bi-parietal diameter (BPD), head circumference (HC), abdominal circumference (AC) and femur length (FL) in estimating the gestational age (GA) and estimated date of delivery. However, as the pregnancy advances these parameters become increasingly unreliable in prediction of GA. Estimation of GA in late second and third trimester accurately still a problem till now. Fetal kidney has been shown a steady growth of 1.7 mm fortnightly (every 2 weeks) along pregnancy and is unaffected by growth abnormalities. Many studies have reported that fetal kidney length (FKL) correlates with the gestational age in late trimester very strong. The study aimed to assess the accuracy of the gestational age estimated by mean fetal kidney length compared to multiple growth parameters like BPD, HC, AC & FL in addition to the actual gestational age derived from the reliable last menstrual period. Methods: Cross sectional hospital based study, was conducted at ultrasound unit;

“…Thus, in the present study mean of kidney length is taken for study without consideration to fetal sex. It is also evident from this study that as the gestational age increases, the length of fetal kidney also increases and there is significant difference in the mean fetal kidney length that is found when lengths are compared across the 22 to 39 weeks of gestational age (0<0.001) 1 . Mean length of the kidney increases with gestational age 9 .…”

Introduction: Fetal kidney length has been studied and shown strongly to correlate with the gestational age in late trimester even in IUGR fetuses. Establishment of gestational age is crucial for obstetricians to plan further treatment of the antenatal patient. Estimation of gestational age of fetus is of great medicolegal Importance. Objectives: The aim of the study was to determine the morphometric development of renal parameters like length, width, and circumference during the fetal period. Material and Methods: The present study was conducted in the Department of Anatomy Kakatiya Medical College, Warangal, having sample size of 100. Foetuses utilized for the study are of gestation period ranging from 20 weeks to 40 weeks. Kidney length, width, and circumference were measured and recorded. Result: A significant and strong positive correlation was found between the crown rump length and gestational age with renal dimensions including length, width and circumference. Conclusion: Growth of kidney was seen to be proportional to gestational age and crown rump length. This will also contribute to imaging of fetal kidneys and detection of kidney abnormalities in intrauterine period and early interventions.

“…Other Indian studies we suggest are Chatterjee et al (28 to 38 weeks) studied 100 pregnant women with known dates of different parity and ages for the period of one year (2015 to 2016) conclude that kidney length can be used as an individual parameter in estimating gestational age, especially in later trimesters, where biometric indices may not be much reliable. 12 Similarly, Monalisa et al (28 to 31 weeks) studied 200 pregnant women with known dates of different parity and ages for the period of two years (2013 to 2015) conclude FKL can be combined with the other four biometric indices to give a fair estimation of gestational age. 13 kidney length could predict gestational age with an accuracy ±9.048 days and predictability when combined with other biometric indices was ±8.299 days.…”

Background: As biometric indices are difficult to obtain or show gross discrepancies with each other or with gestational age in the late trimester, so for accurate dating additional parameter is required. Fetal kidney length is easy to measure and appear reliable in previous studies.Methods: Well dated 121 antenatal women from 28 to 40 weeks of gestation with no obstetric or medical risk factors were recruited and kidney length is assessed in longitudinal scan and maximum length is taken. fetal kidney length derived gestational age compared with other biometrics indices gestational age.Results: Mean kidney length showed significant correlation (r=0.899, p<0.001 value) with increasing gestational age. Mean kidney length dated pregnancy within ±8.5 days.Conclusions: Fetal kidney length measurement correlated well with other routinely used parameters for the estimation of gestational age and can be used as an accurate parameter to date pregnancy in the late trimester.
