The aim of the study was to evaluate the accuracy of computerized axial tomography (CT) in the staging of bladder tumors, comparing preoperative staging defined by tomography with pathological staging determined by the operative specimen, in 128 patients submitted to cystectomy for bladder tumor. None of the patients had been submitted to previous treatment except biopsy if necessary or trans-urethral resection (TUR). In 73 cases preoperative CT was carried out before and in 55 after TUR or biopsy. Overall the accuracy of staging by CT was 40.6%, with 31.3% of overstaging and 28.1% of understaging. Evaluating the accuracy of CT staging carried out before and after endoscopic treatment reveals statistically significant differences between the two groups, with greater accuracy of staging in the cases where CT was carried out before TUR or biopsy (2 = 7.42, p = 0.024). The sensitivity of CT in distinguishing between the presence or absence of infiltration of the pericystium was 64%, with a specificity of 74%. These data suggest that CT is not a reliable technique for the staging of bladder tumors nor for the identification of perivesical tumor growth when present. In the authors' opinion this examination is not accurate enough to base a therapeutic decision on. Considering the high cost we have decided to exclude CT examination from the preoperative staging routine in patients with bladder tumors.
