Brief Summary
The study will be offered to all consecutive patients undergoing scheduled cystoscopy at the Hospitalisation De Jour (HDJ) Chirurgicale, either as part of a diagnostic approach in the event of suspected bladder tumor (exploration of macroscopic hematuria in particular), or as part of the follow-up of a bladder tumor, according to current recommendations (French ccAFU guidelines - update 2020-2022: bladder cancer). Once non-opposition has been obtained, clinical data at the time of inclusion will be collected and pseudonymized. Urine is collected prior to cystoscopy, on voided urine, for a minimum sufficient quantity of 50 ml. The urine sample is then separated into transport jars, one of which is used for standard cytological analysis, the other for VISIOCYT cytology (sent to a laboratory platform). In the event of a tumor or suspicious lesion detected at the cystoscopy, a trans-urethral bladder resection (TURB) will be scheduled. Anatomopathological data from this RTUV will also be collected for comparative analysis to establish the diagnostic performance of the test. The tests performed (apart from the urine sample) are part of the usual care pathway. No additional visits will be specifically requested by the protocol. Data from examinations carried out as part of standard pathology management, or suspected pathology, will be used for this research. At the same time, prospective questionnaires on patients' preferences with regard to the various diagnostic examinations for bladder tumours (discrete choice analysis) will be given to patients and completed at the time of cystoscopy.
