Abstract: Objective:To analyze the ultrasound and CT imaging findings of medullary soonge kidney, to improve the diagnosis level of medullary soonge kidney.Methods: Fourty cases confirmed by pathology or clinical were divided into two groups, group A: 20 cases by B ultrasonic examination, group B: 20 cases by CT examination, The two groups of imaging data were retrospectively analyzed.Results: Ultrasound examination reveals strong echo mass or strong echo plague in the renal medulla, radiate out along the renal pyramid, Strong echo edge is coarse, same size, within small anechoic areas. MSCT finds multiple small mottled stones in the cone. Enhanced scan finds contrast agent filling around renal collecting duct stones, presents visible stripes or small cystic contrast agent accumulation when no stones in renal collecting duct. CT diagnosis coincidence rate is slightly higher than that of ultrasounds, but there was no significant differences in positive rate(x2=2.057,P>0.05).Conclusion: Medullary sponge kidney has a typical ultrasound, CT performance. A combination of them is conducive to clinical diagnosis.
