[Value of angiography and computerized tomography for preoperative evaluation of bladder cancer]

In a comparative study in 30 patients with tumour of the urinary bladder the value of angiographic and computer-tomographic investigation in the proof of tumours and for staging was controlled. In 30% of the cases the angiographic proof was not successful. A concordance to the histologically recognized degree of infiltration could be established by means of angiography in 36.6% and by computed tomography in 86.3%. When it is possible to apply computed tomography for staging we regard the performance of the angiography of the pelvis as no more indicated.
