Early cystoscopy after Bacillus Calmette–Guérin (BCG) induction is essential and plays an important role in ensuring to recognize BCG refractory tumors. Although Photodynamic diagnosis cystoscopy (PDD-C) is proven to be more sensitive than white light cystoscopy (WL-C) particularly for CIS,1 there is currently no recommendation to use PDD for surveillance. WL-C is the gold standard in the surveillance of patients with non-muscle-invasive bladder cancer (NMIBC)1 and the efficiency of intravesical adjuvant BCG in high-risk NMIBC relies on studies performed with WL-C.
