Objective To study the diagnosis and differential diagnosis of renal carcinoma and renal pelvis carcinoma by 128 slice spiral CT.Methods From January 2018 to June 2019,50 patients with suspected renal cancer and renal pelvis cancer were scanned with 128 slice spiral CT,and the pathological results were taken as the gold standard.The diagnostic coincidence rate and CT image characteristics were observed.Results The diagnostic accuracy of 128 slice spiral CT was 96.00%,There was no significant difference between the scanning results and the pathological examination results(χ2=0.355,P=0.837).Renal cancer can be seen as round,round,irregular lesions,isodensity,slightly high density or slightly low density,some calyces and renal pelvis are compressed and deformed,there are necrosis,cystic change,a few calcified lesions,uneven and obvious enhancement in the early stage of enhanced scanning.In the carcinoma of renal pelvis,intrarenal mass type:intrarenal mass,with clear or fuzzy boundary,uneven or even density;infiltrating renal parenchyma type:mass invading renal parenchyma,with moderate or slight contour deformation.Conclusion 128 slice spiral CT can be used to enhance the diagnosis of renal carcinoma and renal pelvis carcinoma.
