Abstract
Purpose
To evaluate the renal cortex stiffness in children with glomerular disease by shear wave based elastography point quantification (ElastPQ), and to investigate the association between shear wave velocity (SWV) in the renal cortex and age in normal children, and the inter-gender differences.
Materials and methods
One hundred and five children who were pathologically confirmed with glomerular diseases were selected as the disease group. Meanwhile, 120 healthy children were selected as the control group. Effective values were measured 5 times at the same kidney sites on each side.
Results
Comparisons of SWV measurements between left and right kidneys in the disease and control groups all showed significant differences (left kidney t = 6.896, P = 0.004; right kidney t = 7.415, P = 0.001). In the control group, left and right kidney SWV measurements were all positively correlated with age (left kidney r = 0.792, P = 0.003; right kidney r = 0.794, P = 0.004). Moreover, inter-gender difference was present in the right kidney measurements.
Conclusions
ElastPQ technology has certain advantages in predicting pediatric glomerular disease compared to conventional ultrasound. ElastPQ technology contributes to the early diagnosis of the disease.
