Measurement of Fetal kidney Length as Parameter for Estimation of Fetal Weight in Sudanese using Ultrasonography

Abstract

Fetal weight is undoubtedly one of the most significant determinants of neonatal survival. It has become increasingly important, especially for the prevention of prematurity, evaluation of pelvic disproportion before induction of labor and detection of Intra Uterine Growth Restriction. The aim of this study was to evaluate the validity and efficiency of prediction of fetal birth weight by measuring fetal kidney length. The study conducted at Academy Charity Hospital at Khartoum state, 50 pregnant women were enrolled in the study and their fetal biometry was measured. Fetal both kidneys’ length were measured and correlated to fetal weight. The result of the study showed that there was linear and strong correlation between right kidney length and fetal weight (p˂ 0. 05). This correlation was also noticed at the left kidney, but was not strong and non-significant. The model derived from this study indicated that the fetal kidney length can be used to estimate fetal weight in combination with biparietal diameter and femur length.
