Estimation of gestational age plays an important role in quality maternity care. Ultrasound provides an accurate method of determining fetal age in utero. A prospective study was done in 150 pregnant women with low-risk pregnancy after 28 weeks of gestation who were sure of their last menstrual period or had underwent dating scan. The aim of this study was to determine the accuracy and application of fetal kidney length (FKL) measurement in determining the gestational age of the fetus in the third trimester and compare its accuracy with that of other fetal biometric indices [biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), and femur length (FL)]. The FKL measurements showed that there is a linear relationship between FKL and gestational age. The mean kidney length in mm approximates the gestational age in third trimester as predicted by BPD, HC, AC, and FL. The FKL dates the pregnancy more accurately (correlation coefficient 0.98) when compared with BPD, HC, AC, and FL. The results obtained concluded that FKL can be used as a reliable parameter for determination of gestational age.

Background: CPR is emerging as an important predictor of adverse pregnancy outcome and helps in management of high risk pregnancy. Therefore we undertook the study to find the correlation of CPR with perinatal outcomes in women with hypertensive disorder complicating during third trimester.Methods: 128 patients with hypertensive disorder of pregnancy, ≥32 weeks of singleton gestation, were randomly selected during their hospital visit. They were subjected to USG Doppler study to calculate MCA/UA pulsatility index-CPR. The CPR<1 was considered abnormal and >1 as normal. These results were compared with the perinatal outcome and adverse fetal outcome.Results: The present study revealed that the incidence of adverse outcomes like Apgar score <7 (36.5%), still birth (15.9%), NICU admission (69.8%) and LBW i.e. <2500 gm (68.3%) were significantly higher in abnormal CPR than normal CPR.Conclusions: Abnormal CPR is valuable in predicting the outcome of hypertensive disorders in pregnancy. CPR is an easy procedure which can be included in the routine antenatal sonographic evaluation to predict poor perinatal outcome and to detect or recognize those fetuses at risk.
