Ultrasonographic Renal Length and Parenchymal Thickness in Normal Sudanese Population

This study was intended to measure the ultrasound normative values of renal length and parenchymal thickness in adult Sudanese population in order to establish their reference value for Sudanese population while no recorded reference value in literature for them. Ultrasonographic kidney measurements were performed on 77 adult patients without known kidney lesions. Measurements included length and parenchymal thickness. The effect of age, gender, site (left and right side) and height was statistically analyzed. All normal patient was included in this study while any renal disease were excluded. This study was include (35) males and (42) females. The mean renal lengths were (10.15 0.78) and (10.33 0.80) cm for the right and left kidney respectively. The mean parenchymal thicknesses were (1.4714 0.33cm) for the right kidney and (1.7169 0.36cm) for the left kidney. These result were correlated with age, gender, site, and height which showed that there is no significant difference between right and left renal length, but there was significant difference between right and left parenchymal thicknesses. The significant effect of age was found only in left renal length. The significant effect of gender was noted only in the right parenchymal thicknesses. No significant difference among height groups for renal length, but there was significant difference in right parenchymal thickness. The study concluded that normal value of left renal length was affected with age and normal parenchymal thickness was affected with site (left or right). The right parenchymal thickness was affected with gender and height. Establishment of normal renal values of renal length and parenchymal thickness in Sudanese population will help us in evaluation of patients with chronic renal disease.
