Abstract
Accuracy in estimation of gestational age (GA) has
become more demanding as technology used in
ultrasonography has become more advanced. Patient‘s
expectations have also increased and they expect exact
estimations to plan their pregnancies.
Fetal kidney length (FKL) alone or in combination
with other biometric indices can be used in estimating GA
more precisely.
An accurate estimation of gestational age is
fundamental for better management of pregnancy, especially
high-risk pregnancy. It is helpful in pregnancy to know the
certain date of conception.
Sonographic measurements of fetal parameters are the
basis for accurate determination of gestational age and
detection of fetal growth abnormalities. selection of the
most useful single biometric parameter depends on the
timing and purpose of measurement and is influenced by
various factors where in second & third trimester kidney
length estimation was much better to depend upon as a
single parameter than BPD which is much affected by
engaged head & also better than AC that is affected by
IUGR.
Establishing the gestational age of the fetus,
especially in late trimester is a challenge to aptly treat the pregnant woman. Ultrasound parameters like BPD, HC, and
AC & FL in second and third trimesters are not very reliable
for dating the pregnancy.
In our study Fetal kidney length has been studied and
shown to strongly correlate with the gestational age in late
trimesters even in IUGR fetuses.
