ABSTRACT
Objective To discuss the MSCT diagnosis and differential diagnosis of primary ureteral carcinoma and non-specific u-reteritis.Methods The pre-contrast and three-phase post-contrast MSCT scans were performed in a group of 12 patients with prima-ry ureteral carcinoma and 5 patients with non-specific ureteritis confirmed by pathology.The MPR,CPR,CTU images were genera-ted from raw data.The MSCT image feature of the primary ureteral carcinoma and non-specific ureteritis were observed respective-ly.Results ①1 2 cases of primary ureteral carcinoma pathologically diagnosed as transitional cell carcinoma,The manifestations of MSCT:9 cases (9/12)showed irregular thickened wall and eccentricity lumen stenosis,5 cases had soft tissue mass in lumen,3 ca-ses (3/12)showed irregular thickened wall and central lumen stenosis.The lesions lumen was significant stenosis,edges and broken ends were irregular.②The non-specific ureteritis manifestations of MSCT:1 case (1/5)showed irregular thickened wall and eccen-trical lumen stenosis;3 cases (3/5)showed irregular thickened wall and central lumen stenosis,and the edge of obstruction was rel-atively smooth.1 case (1/5)prompted hydronephrosis and hydroureter.The lesions lumen was still relatively smooth,had no sig-nificant thickening.③On non-enhanced CT,primary ureteral carcinoma attenuation was equal to the non-specific ureteritis (P>0.05).The degree of enhancement was higher than non-specific ureteritis during all enhanced phases (All P<0.05).Conclusion Main performance characteristics of primary ureteral carcinoma and non-specific ureteritis can both cause the ureteral wall thickening in different appearances and degrees.The MSCT enhanced scan with varies images processing techniques such as MPR,CPR and CTU showed some clinical application potentiality in both diseases diagnosis and discrimination.
