Results
There were no statistically significant differences between the mean IL-1, IL-6, IL-8 and neopterin levels of the patient and control group before initial TURBT. In the patient group, there were no statistically significant differences in the IL-6 and IL-8 levels after both TURBT and intravesical BCG therapy. The mean of preoperative IL-1 and neopterin levels significantly decrease after TURBT (p<0.05=). However this reduction do not continue after intravesical BCG instillations.
