Computed tomography in staging of bladder carcinoma

A comparison was made between the use of clinical methods and computed tomography for staging of carcinoma of the urinary bladder in 52 patients. CT was found to be the most reliable method for determining the perivesical extension of the tumour. It is of value for determining the extent of the tumour before irradiation and for establishing the tumour response. It was less reliable for diagnosing metastases in the lesser pelvis.
