Interventions
Gold Standard:The kidneys were scanned by thin-section CT (0.625 mm) , and the maximum diameter, volume and location of renal stones were measured and recorded.
Index test:The kidneys of the subjects were scanned from multiple angles, and three-dimensional reconstruction was performed by CT-US fusion ultrasound to obtain the volume data of the stones.
