2. Those who were found during the procedure (outpatient diagnostic cystoscopy) to carry suspicious bladder lesion(s)
3. Provision of informed consent

Study & Design

- Study Design
- Not specified
- Primary Outcome Measures
Name Time Method Image quality is measured using absolute category rating (ACR) following the diagnostic imaging. ACR was based on a modified-for-images, double stimulus, continuous quality scale (DSCQS) method (the standard for subjective video quality tests). Mean opinion scores (MOS) on the ACR scale are compared between the SPIES cyctoscopy group and the WLI cystoscopy group.
- Secondary Outcome Measures
Name Time Method Correlation of the difference in MOS (DMOS) of the two groups with demographic data of study participants (age, medical status, sex, and previous experience with image enhancement systems for the diagnosis of NMIBC)
