The role of computerized tomography in the assessment of perivesical invasion in bladder cancer

BACKGROUND: The aim of the present study was to identify the contrast patterns of a tumor, and to evaluate the possibility of assessing the invasion of the perivesical fatty tissue in bladder cancer. MATERIAL AND METHODS: In this study, 26 patients with bladder cancer were included. Multiphasic CT examination was performed to determine the stage of the disease before radical cystectomy. RESULTS: There were statistically significant differences in tumor and perivesical fatty tissue densities between pre- and post-contrast phases (p<0.05). CONCLUSIONS: Increases in focal density suspected of being invasion of the perivesical fatty tissue can show perivesical invasion with high specificity.
