Determination of gestational age by fetal kidney length during 28-36 weeks of pregnancy by ultrasonography
Background: Accurate Gestational Age [GA] assessment is of great importance for sonologists and obstetricians in evaluations of fetal development and assessment of intrauterine growth. Aims: To establish a correlation between Fetal Kidney Length [FKL] with GA during 28-36weeks of pregnancy through u...

| Summary: | Background: Accurate Gestational Age [GA] assessment is of great importance for sonologists and obstetricians in evaluations of fetal development and assessment of intrauterine growth. Aims: To establish a correlation between Fetal Kidney Length [FKL] with GA during 28-36weeks of pregnancy through ultrasonography and Comparing the accuracy of gestational age derived from mean FKL with other biometric parameters like bi-parietal diameter, head circumference, femur length and abdominal circumference and by the Last Menstrual Period [LMP], Materials & methods: Sixty singleton uncomplicated pregnant women of different parity underwent standard ultrasound examination for foetal biometry like Bi-Parietal Diameter [BPD], Head Circumference [HC], Abdominal Circumference [AC], Femur Length [FL] and kidney length [bipolar] measurement in sagittal plane. The maximum kidney length was taken from upper pole to lower pole of any one foetal kidney in sagittal plane which was compared with GA obtained by LMP. The measurements obtained were statistically analysed by interclass correlation coefficient by using IBM- SPSS trial version 21.0 software. Results: There was a statistically significant positive correlation between the GA estimated by clinical method [LMP] and FKL. The interclass correlation coefficient was 0.79 with a 95% confidence interval of 0.67 to 0.87 [p<0.001]. FKL could predict GAwith an accuracy of± 2.19 wks [95% CI 2.03 to 2.35 wks]. Conclusion: This proves that kidney length can be used as an additional parameter to confirm the GA and also essential in detection of intrauterine kidney development and in the evaluation of fetal growth. |
