title: [Radiogenic alterations following telecobalt irradiation of urinary bladder tumors].
abstract: The investigation reports on the frequency of radiogenic changes after high dosage radiotherapy of carcinomata of the urinary bladder carried out on 109 patients. Severe changes on urinary bladders and rectum were established in ca. 15% of the patients, 61.5% were clinically without any complaints. The importance of the single focus dose for the complication rate is proved and an adequate radiotherapy regime for the reduction of late sequelae is recommended. With regard to the necessity of the telecobalt irradiation one must cope with smaller lesions.
