Ultrasonic Evaluation of Fetal Kidney Length in Second and Third Trimester Correlated with Gestational Age in Salaldeen General Hospital

Abstract

Background: Various organs are measured to estimate the gestational age of the fetus.. Assessment of the fetal kidney length alone or in combination with other biometric parameters can be used in gestational age calculation more precisely in the first and second trimesters.
Aim: The current study aimed to establish the correlation between fetal kidney length and gestational age in the second and third trimesters.
Materials and Methods: A cross-sectional study was conducted in Saladin General Hospital /Gynecology and Obstetrics department during the period from 1st of January to 30th of June 2022. A convenience sample of 100 pregnant women who attended the Gynecology and Obstetrics department. Inclusion criteria included pregnant women who were in the second or third trimester with a history of regular menstrual cycles
Results: According to the results of the current study, there were significant positive correlations between the right kidney length, left kidney length and gestational age according to the last menstrual period in weeks. There was a significant difference between different gestation ages according to the menstrual cycle regarding the mean of the right or left kidney length (mm). in addition, a significant correlation was obtained between the gestational age according to the last menstrual period length, biparietal diameter, head circumference, abdominal circumference, and femur length. In conclusion, fetal kidney length is a reliable parameter for the determination of gestational age in the second and third trimesters of pregnancy and can be used when other methods like the last menstrual period are unknown.
