Abstract:
Objective To assess the imaging characters and clinical applications of triphasic spiral computer tomography(CT) scanning in ureteral lesions.Methods We analyzed of 76 consecutive cases of clinically evidenced ureteral lesions using the cross-sectional images and CTU derived from triphasic spiral CT scanning retrospectively.Results Twetny-four cases of 76 ureteral lesions patients were diagnosed as ureteral tumor,resulting in severe urinary tract obstruction.The shape,size,number,regional ureter wall inflammatory infiltration of visible mass were verified as well.Twetny-six cases were caused by ureteral stones.The "edge" sign was shown clearly.Ten cases were ureteral inflammation,characterized by different ureteral wall thickening and enhancement feature.Eight cases were ureteral tuberculosis that secondary to renal tuberculosis.Uneven ureteral wall thickening,stiffness and mild to moderate density were shown in CT scanning.Ureteral congenital malformations were found in 3 patients.The other five cases were caused by exogenous factors.CT scanning could identify the mass general profile.Conclusion Triphasic spiral CT scanning plays an important role in ureteral lesions diagnosis and differentiation from other similar diseases.
