Is the Normal Looking Bladder Mucosa on WL Cystoscopy During TURBT Really Normal and Can NBI Detect Hidden Tumor

Can Narrow-band Imaging Detect CIS/Tumor in Normally Looking Bladder Mucosa on White Light Cystoscopy During Transurethral Resection of Bladder Tumor?

As every urologist does transurethral resection of bladder tumor. So there are instances in which the operating surgeon is not sure whether the normal-looking mucosa or the inflammatory changes are really benign or if we are missing the CIS/bladder cancer.

This is basically the observational study. in which we want to clarify that the normal-looking mucosa on white light cystoscopy is normal in reality or we are missing CIS/bladder tumor.
