Abstract:
Objective To invesigate the value of contrast-enhanced spiral CT scan in diagnosing renal pelvic carcinoma.Methods All 35 cases with renal pelvic carcinoma confirmed by surgical pathology underwent plain and contrast-enhanced (including 4 phases) spiral CT scans before operation.CT data were reviewed retrospectively in comparison with surgical and patholgical results.Results CT findings of renal carcinoma could be classified into 3 types:type Ⅰ,the lesions limited within the renal pelvis in 25 cases;thype Ⅱ,the lesions were out of the renal pelvis and had indefinable margins with the renal parenchyma in 6 cases;type Ⅲ ,only showed the pelvic wall thickened with hydronephrosis in 4 cases.On contrast-enhanced CT scan,inhomogeneous enhancement of the lesions was presented in cortical phase,the intensity of enhancement was not obviously changed in 13 cases in parenchymal and excretion phases,but the lesions were still hypointense in comparison with renal parenchyma,14 cases demonstrated inhomogeneous enhancement of the lesions in delayed phase.Conclusion Contrast-enhanced spiral CT scanning is valuable in diagnosing renal pelvic carcinoma and renal delayed phase should be emphasized.
