Measurement of Normal Kidneys Length and Volume in Sudanese Children using Ultrasound Imaging

Abstract

This was descriptive study concluded in Khartoum state and western Kurdufan state – Sudan, from December 2016 to January 2017. This study done to measure the normal kidneys length and volume in Sudanese children using B-mode ultrasound imaging. The problem of this study was to identify kidneys length and volume to lay the foundation for faster and easier diagnosis of renal pathological conditions and to revel if the growth kidney affected by geographic factors or not. The study aimed to measure and correlate the length and volume of the right and left kidneys and to correlate the body characteristics, gender and deferent areas to these measurements. The data collected from 104 volunteers using master data sheet in order to analyze it and calculate the mean normal value of kidneys measurements. The study found that the mean value of right and left kidneys length was 8.034 cm and 8.212 cm respectively, and the mean value of right and left kidneys volume was 55.935 cm³ and 64.497cm³ respectively. Left kidney was larger than right kidney in all measurements and the significant difference between the right and left kidneys found. Significant difference between right and left kidney measurements in different geographic areas (Khartoum and Western Kurdufan) also found. No significant difference found in respect to gender. Right kidney length correlated with height and BMI. Right kidney width correlated with body height and body weight. While left kidney width only correlated with body height. AP diameter for right and left kidney correlated with body height. The right kidney volume correlated with body weight and BMI while left kidney volume correlated with body height and BMI. The study recommended that further studies to overcome the limitations specially that related to age and number of volunteers.
