Clinical Evaluation of Multi-slice Spiral CT Urography in the Diagnosis of Pyelic and Uretal Disease / 实用放射学杂志

ABSTRACT

Objective To evaluate the diagnostic value of multi-slice spiral CT urography(MSCTU)in pyelic and uretal disease.Methods 46 cases of pyelic and ureter disease with integrated clinical data were collected in two years,all cases were undergone multi-slice spiral CT contrast-enhanced scanning,the excretory-phase images were transferred to the workstation and shaded volume rendering(SVR),maximun intensity projection(MIP),multiplanar reconstruction(MPR)and curved planar reconstruction(CPR)were performed.Results In 46 cases,16 pyelic and ureteral calculus,12 congenital deformitions(including pelviureteric duplication malformations,retrocaval ureters,ureteropelvic junction stenosis,supern-umerary kidneys),5 inflammatory stenosis,7 primary pyelic and ureteral cancer,4 ureters were involved by bladder cancer and 2 compressive lesion were found.Conclusion MSCTU has obvious advantage in the diagnosis of pyelic and uretal disease.
