Background and Objective: In order to make precise estimations regarding the age of the fetus and monitor the development of various foetal organs, it is important to possess precise knowledge of the date of birth. Additionally, it aids in the precautionary measures against prenatal and postnatal problems for the neonate. A lack of awareness regarding the last menstrual period (LMP) is a prevalent issue among prenatal mothers. In such circumstances, the computation of the delivery date would pose a challenge. Several studies indicate that as many as 30% of women were uncertain about their Learning Management Plan (LMP). Obstetricians must exercise caution when the precise LMP is unclear to avoid post maturity and preterm deliveries.

Methods: The current investigation constitutes a prospective comparative analysis at the Department of Obstetrics and Gynaecology, SFTMC College & Dr. BR Ambedkar Memorial Teaching Hospital, Agartala, Tripura, India. A sample size of 150 individuals, aged between 20 and 35 years, was included in the study conducted in the year February 2011 to January 2012, specifically after 24 weeks of gestational age. The gestational age was determined through clinical examination by palpating the patient's fundal height. Subsequently, ultrasonography was employed to determine the foetal kidney length (FKL) and other pertinent foetal characteristics.

Results: In this study, the duration of BPD varied from 28 to 40 weeks, with an average BPD of 35.25+2.67 weeks. HC spanned from 27 to 40 weeks, and the average BPD was 35.35+2.88 weeks. MKL ranged from 27 to 41 weeks, with an average MKL of 35.93+3.49 weeks. The combined values of several factors in GA varied from 27.8 to 39.6, with a mean of 3.5.36+2.7.

Conclusion: The FKL is a valuable tool for evaluating gestational age. Based on our research findings, we assert that a notable association exists between the length of the deadly kidney and the gestational age. Therefore, the fetal kidney is a suitable method for estimating gestational age..
