Sonographic Measurement of Fetal Kidney Length as Parameter for Fetal Weight Estimation for Sudanese Population

Background As far as independent extrauterine existence and optimum survival of the fetus is concerned birth 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. Objective This study aimed to evaluate the validity and efficiency of prediction of fetal birth weight by measuring fetal kidney length Material and methods Descrepive quantitative cross sectional study was conducted in AL sheikh hospital Omdurman during period from August 2012-2015 to evaluate the validity of fetal kidney length for fetal weight estimation using Ultrasonography. A total number of 384 pregnant women aged between 15-45 years old attended for routine check up were studied after 17 years old of gestational, and the data analyzed by Statical package for social science (SPSS). . The results The study revealed that there was linear and strong correlation between the mean of (LMP) Gestational age with biometric indices, kidney length and fetal weight (p 0.05). The was strong a significant correlation between fetal weight and fetal kidney length (p 0.05). There was no statistically significant correlation between the mean of the FWT and maternal age, weight, high, body mass index, parity and fetal gender (p0.05). The module derived indicated that the fetal kidney length can estimate fetal weight in combining with biparietal diameter, femur length with estimate error of 319 grams Conclusion It concluded that the fetal kidney length is a valuable tool for fetal weight estimation.
