The normal reference values and estimation formulae of renal structural parameters in Chinese children based on large-sample CT data

Purpose Our aim was to investigate the normal reference value and establish an estimation formulae for renal structural parameters (RSPs) based on large-sample CT data of Chinese children, which can provide a clinical assessment kidney development diseases in children. Materials Methods A total 438 children aged 0–17 years with images basic indices were continuously collected. The bilateral RSP, including length (RL), width (RW), thickness (RT), volume (RV), cortical (RCT), artery diameter (RAD) value, measured. Kendall's rank correlation used analyze between RSP sex. Pearson's age, height weight. Differences kidneys analyzed via paired samples t-test. Multiple linear regression multivariate relationships formula RSP. Results showed dynamic increasing trend except values. ranges (95% confidence interval) each age group determined. Pearson analysis demonstrated strong correlations (RL, RW, RT, RV, RCT and, RAD) (age, weight), exhibiting greatest coefficient, followed by or that none RSPs correlated RL, RV RAD left larger than those right kidney, RT exhibited opposite results. significant relationship RCT) variables indices. calculating established. Conclusion This is first study report trends, values data. These results references assessing adequate growth disease damage
