PD26-04 A RANDOMIZED STUDY TO COMPARE OUTCOMES OF INTRAVESICAL CHEMOHYPERTHERMIA WITH MITOMYCIN C VS INTRAVESICAL BCG FOR INTERMEDIATE AND HIGH RISK NON-MUSCLE INVASIVE BLADDER CANCER (NMIBC)

50%; otherwise, the results were considered inaccurate. The evaluation was performed using a five-fold cross-validation test. RESULTS: For the test dataset, containing 1,650 cystoscopy images (WLI 217 and NBI 64 images of bladders with tumors and WLI 1,104 and NBI 265 images of normal bladders), and at the threshold where the F1 score in the training dataset was the maximum, the proposed AI model exhibited average sensitivity, specificity, and F1 scores of 83.7%, 82.3%, and 0.637, respectively. We adapted the AI model to all frames of a clinical cystoscopy video of a case and detected the lesion sites. CONCLUSIONS: By applying the analysis of still images to video, real-time detection of bladder tumor lesions for both WLI and NBI is possible, with AI showing the probability map of the lesion sites using the proposed method. This may improve diagnostic accuracy by creating awareness among urologists of all skill levels and by encouraging more robust observations.
