Conditions

Non-muscle-invasive bladder cancer (NMIBC) Cancer Bladder (urinary) cancer

Interventions

All images used for this study are captured during cystoscopy of patients with suspicious bladder lesions, as a standard diagnostic procedure. Concretely, patients scheduled for an outpatient diagnost

Eligibility

All

Inclusion criteria

Inclusion criteria: Health professional inclusion criteria: All registered members of the HUA (urologists and residents in urology) Patient inclusion criteria: 1. Patients with a formal indication for an outpatient dianostic cystoscopy at our department (such as suspicion of bladder tumor, or patients on a regular follow up after bladder tumor resection) 2. Those who were found during the procedure (outpatient diagnostic cystoscopy) to carry suspicious bladder lesion(s) 3. Provision of informed consent

Exclusion criteria

Exclusion criteria: Health professional exclusion criteria: Not meeting the inclusion criteria. Patient exclusion criteria: 1. No indication for an outpatient dianostic cystoscopy at our department (e.g. healthy volunteers), 2. No suspicious bladder lesion during the procedure (outpatient diagnostic cystoscopy) 3. Not providing informed consent

Design outcomes

Primary

Measure	Time frame
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

Measure	Time frame
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)	—
