“…Kaul I et al [6] also advocated that the single most accurate parameter for estimating GA is the FKL. Kiran L et al [11] in their study determined that FKL correlated well with GA estimated from standard fetal biometry and can be used as an independent parameter in estimation of fetal GA. Das SK et al [12] concluded that FKL showed a strong correlation with GA compared to other conventional parameters and can easily be included in routine obstetric scan to enhance the accuracy of GA measurement and in cases where conventional parameters are difficult to obtain.…”

Accurate assessment of gestational age (GA) is pivotal to provide good quality maternity care. Reliability of routinely used ultrasonographic biometric parameters like Biparietal diameter (BPD), Head circumference (HC) and Femur length (FL) decrease with increasing GA.Fetal kidney length (FKL) and transverse cerebellar diameter (TCD) have been shown to strongly correlate with GA in 2nd and 3rd trimester.The present study was conducted on 150 pregnant women at 20 weeks of gestation to evaluate the role of FKL and TCD in estimation of GA and compare their accuracy with other established biometric indices. The GA of the included women was confirmed by early dating scan and exact Last Menstrual Period (LMP).BPD,HC,FL,FKL and TCD were calculated in millimetres (mm) and GA was calculated by using these parameters individually. Standard deviation and standard error of the GA calculated at 20 weeks was lesser for TCD and FKL than BPD, HC and FL with p values of 0.01636 and 0.0129 respectively. It was also observed that values of TCD and FKL in mm correspond to GA in weeks. So it was concluded that FKL and TCD can be used as an individual parameter in estimating GA in mid trimester in patients presenting for the first time with uncertain dates, lack of early dating scan or with IUGR.

Precise evaluation of gestational age is essential for quality maternity care. Ultrasonography is the most readily available and reliable method to establish gestational age. This study aims to use the length of the fetal kidney as a reliable parameter to measure gestational age in late second and third trimesters. Objective: To determine the relationship between fetal kidney length and gestational age in weeks during the late 2nd and 3rd trimester of normal pregnancy. Methods: It was a prospective cross-sectional study conducted on 105 singleton normal pregnant females between 24th and 40th weeks of gestation who came to the obstetrics and gynecology department at a private sector hospital in Kharian, Pakistan. The duration of the study was four months. Bi-parietal diameter, femur length, and fetal kidney lengths were measured. Statistical analyses were applied using SPSS version 22.0. Results: A moderately significant positive correlation was identified between different gestational age measuring parameters and fetal kidney length. The correlation was significant at the level of 0.01. The correlational values of GA according to LMP with FKLL and FKLR were (r= .85**) and (r= .87**) respectively. GA with BPD indicates a moderately significant positive correlation with FKLL and FKLR (r= .94**) and (r=.94**). GA with FL also shows a moderately significant positive correlation with FKLL and FKLR (r= .83**) and (r= .83**), respectively. Conclusion: In conclusion, fetal kidney length in millimeters correlates well with gestational age in weeks and shows linear growth with gestational age throughout pregnancy. Gestational age estimated from fetal kidney length gives improved dating of fetal age
