Abstract：Objective: To investigate the diagnostic value of multi-slice CT(MSCT) and three dimensional reconstruction in primary ureteral carcinoma. Methods: Sixteen cases with primary ureteral carcinoma proved by operation or biopsy pathology were collected in the study. All patients had undergone MSCT scanning with multi-planar reformation(MPR), curved planar reformation(CPR), maximum intensity projection (MIP) and volume rendering technique(VRT). Results: The axial CT images displayed intraureteral soft tissue mass with thickened wall. The foci had mild or moderate enhancement after contrast injection and the peak enhancement was in the venous phase. The MPR and CPR images can clearly demonstrate the location, extent, number, thickened ureteral wall and adjacent invasion of the tumor. CPR image can exhibit the whole range of ureter in one plane, MIP and VRT images were similar to intravenous urography. Conclusion: MSCT and three dimensional reconstruction had very important value in the diagnosis of primary ureteral carcinoma, it can supply valuable information for clinic in treatment planning and prognosis evaluation.
