Angiography in the evaluation of carcinoma of the bladder

Pelvic angiography using the Seldinger technique as a method for more accurate staging of bladder tumors is discussed. This method offers an excellent demonstration of the depth of infiltration and perivesical extension of a tumor. The procedure is considered safe, and involves no technical difficulties. In cases where there has been previous surgery and radiotherapy, there may be some risk of overstaging. We consider this method an extremely valuable tool for staging bladder tumors more accurately, and, therefore, for providing better treatment.
