Recurrence rate of the bladder tumor was studied on 278 patients who were treated during the period from 1961 to 1976. 1) The sex ratio was 6(M) : 1(F) and there was no sex difference in the recurrence rate. 2) The ages of the patients ranged from 19 years to 84 years with three fourths of the group between the ages of 50 and 80 years. 3) We recognized the higher recurrence rate in the tumors originated on the bladder neck. 4) The recurrence rate showed significant difference between papillary pedunculated tumor and non-papillary sessile tumor. 5) The larger the size of tumor the higher recurrence rate was observed. 6) The multiple tumors showed higher recurrence rate than the single tumors.
