Residual tumor rates of the sum of risk (smoking, pathological stage, number of tumors) due to clinical pathological factors at the time of the first PDD‐TURBT. The risks of current/past smoking history and pathological stage of pT1 or pTis at the time of the first PDD‐TURBT. Multiple tumors were each set to 1; the residual tumor rates of the group with a sum of risk score of ≤1 (n = 48), and the group with a sum of risk score >2 (n = 129) was analyzed with a significant difference test using Fisher’s exact test. *Number in parentheses; number of residual tumor/number of patients.
