* Upper tract evaluated using standard of care throughout duration of the study
* Induction intravesical therapy initiated within four weeks of TURBT

Exclusion Criteria:

* Variant histology consisting of less than 50% urothelial carcinoma

* Patients who are noncompliant with the study protocol

About the study

Comparing white-light cystoscopy (WLC) and blue-light cystoscopy (BLC) in TURBT for high risk (HR) non-muscle invasive bladder cancer (NMIBC) patients is crucial to determine the most effective method for reducing residual disease burden and improving recurrence-free survival. Enhanced visualization with BLC may lead to more accurate resections, potentially decreasing recurrence rates and improving long-term outcomes for bladder cancer patients. Patients will be randomized to either WLC TURBT or BLC TURBT, and outcomes will be measured using standard-of-care testing with cystoscopy and cytology, along with minimal residual disease (MRD) burden evaluation using urine next-generation sequencing.
