ObjectiveTo discuss the value of CT in the diagnosis of ureteral tumor. MethodsWe retrospectively analyzed the CT features of 52 patients with ureteral tumor confirmed by operation, pathology and immunohistochemistry between August 2011 and July 2013. All patients underwent CT plain scan followed by enhanced scan, and 13 patients underwent CT Urography imaging. ResultsUreteral tumors occurred mainly in the lower ureter (20 cases), and 5 cases occurred in the upper ureter, 8 cases in the mid-upper ureter, 11 cases in the middle ureter, and 8 cases in the mid-lower segment. The lesions showed a lump or thickening of the wall, and the indirect signs included renal pelvis, ureter, bladder and ureter angle changes. ConclusionCT is valuable in the diagnosis of ureteral tumor. CT Urography can be very intuitive, multi-dimensionally displaying the wall and conditions outside the cavity, which has a great significance in guiding clinical operation.
