Comparative Study of Gestational Age Using Mean Fetal Kidney Length and Other Sonographic Fetal Parameters in Singleton Pregnancy After 24 Weeks

Abstract

Introduction: To accurately estimate the fetus age and follow up on the growth of different fetal organs, it is vital to know the accurate date of birth. It also helps to prevent prenatal and postnatal complications for the newborn. It is common for antenatal mothers to be unaware of last menstrual period (LMP). In such situations, it would be difficult to calculate the delivery date. According to various studies, up to 30% of women were not sure of their LMP. The treating obstetricians would have to be very careful when the exact LMP is unknown in order to prevent post maturity and prematurity deliveries. Material And Methods: The present study is prospective comparative study of Department of Obstetrics and Gynaecology in Guntur Medical College and Hospital, Andhra Pradesh, India. After 24 weeks of gestational age are included who are at age between 20-35 yrs which is of 200 sample size in the year 2020-21. Clinical assessment of gestational age was done by palpating the fundal height of the patient. Following this using ultrasound, meam fetal kidney length (FKL) along with other fetal parameters were calculated. Result: In the present study, BPD ranged from 28-40 wks, whereas the mean BPD was 35.25+2.67 HC ranged between 27-40 and the mean BPD was 35.35+2.88 MKL ranged between 27-41 and the mean MKL was 35.93+3.49. Upon the composite of multiple parameters GA ranged between 27.8-39.6 and the mean was 3.5.36+2.7. Conclusion: The FKL is very much useful in assessing the gestational age. From our study we state that there is a significant correlation between fatal kidney length and the gestational age. Hence fetal kidney is appropriate in estimation of gestational age.
