Abstract:
Objective To explore the diagnostic value of three-dimensional ultrasound parameters-vascularity index (VI) and the volume of kidney in chronic kidney disease (CKD). Methods A total of 80 CKD patients at different stages and 30 healthy adults were enrolled in the study. VI and the renal volume were calculated with three-dimensional ultrasound, while resistance index (RI), cortical thickness (CT) and the volume of kidney were calculated with two-dimensional ultrasound, and the correlation of those parameters were analyzed statistically. Results VI of CKD2 patients reduced significantly compared with the control group, and RI of CKD3 patients increased significantly, CT of CKD3 patients reduced significantly. The diagnostic sensitivity, specificity and diagnostic value of VI in patients with early and late CKD were all higher than thpse of RI. Compared with the control group, three-dimensional ultrasound of renal volume and two-dimensional ultrasound volume of CKD 1 patients increased significantly, three-dimensional ultrasound volume of CKD2 patients reduced significantly, and two-dimensional ultrasound volume of CKD4 patients reduced significantly. There was significant negative correlation among VI, three-dimensional ultrasound volume, CT, two-dimensional ultrasound volume and pathological change scoring (r=-0.67, -0.52, -0.43, -0.52). Conclusion VI and three-dimensional ultrasound volume can detect renal function damage more earlier and sensitively than RI and two-dimensional ultrasound volume.
