[Results of radiotherapeutic optimization within the scope of combined operative-radiologic therapy of urinary bladder cancer].

The results of a prospective randomized clinical study for the comparison of a uniserial irradiation with a biserial irradiation are demonstrated. The investigations were performed on altogether 191 patients. Patients after cystectomy and supravesical by-pass of the urine were excluded. The operative treatment consisted of TUTUR, transvesical tumour resection or partial resection of the urinary bladder. According to the life table method the uniserial irradiation a survival rate of 52% and for the biserial irradiation of 39% after 54 months was calculated.
