NEW TECHNIQUE OF TRANSCYSTOSCOPIC INTRACAVITARY IRRADIATION FOR CARCINOMA OF THE URINARY BLADDER

Abstract

A remote controlled transcystoscopic intracavitary after-loading unit has been introduced to irradiation therapy of bladder carcinoma. Using intense radiation therapy, a significant dose can be delivered to the tumor in a short period of time. Uning transcystoscopic intracavitary irradiation, we have treated fourteen patients with transitional cell carcinoma of the bladder. Nine patients initially showed a complete response, although within several months, 3 patients subsequently showed recurrence in a different part of the bladder. Utilizing this technique, technical difficulties and severe complications were not encountered. The preliminary results and actual technique of transcystoscopic intracavitary irradiation are reported.
