In this study, the new aScope 4 Cysto is used to see if this new single use, flexible cystoscope performs as well as other routinely used flexible cystoscopes. This study will be done in patients who come to the clinic for either a diagnosis of their urethra and bladder or for a small intervention. For an intervention a lesion or tumor is resected, a stent in the ureter is taken out, or an injection in the bladder wall is given. The flexible cystoscope is passed into the urethra and bladder for visual inspection of the bladder and urethra. It will give information on how well the structures of the urinary tract and bladder can be viewed including any abnormalities that are present. If an intervention is performed the aScope 4 Cysto will be used with an endoscopic accessory.
Clinical Phase: pre-CE study Design: A prospective, multicenter, single- arm open-label clinical study on the performance and safety of Ambu® aScope™ 4 Cysto and aView™ Urologia, a single-use, flexible cystoscope for flexible cystoscopy Population: Adult subjects (≥ 18 years) undergoing flexible cystoscopy for diagnostic or therapeutic purposes. Planned Sample Size: A total of 80 patients will result in a maximum (if the true proportion is 50 %) width (i.e. the difference between the point estimate and the upper, or lower, limit of the confidence interval) of the two-sided 95 % confidence interval for the binary variable "Performance level acceptable" to be 11%. This width is considered to be useful in the interpretations of the results from this part of the trial. Study duration: Screening, procedure and follow-up will take 14 days maximum. A follow-up telephone call at 7 days post procedure is performed to record any adverse events post-procedure. Planned Trial Period: 3 months Investigational Device: Ambu® aScope™ 4 Cysto and aView™ Urologia. A pre-CE, single use cystoscope.

Performance of the cystoscope
Rate of completion of procedure with Ambu® aScope™ 4 Cysto and aView™ Urologia (yes/no, yes applies to 80% of the procedures)
Time frame: follow up immediately after procedure
Overall performance
The overall performance will be further assessed by using a 5-point Likert scale with a minimum of one (=worst possible) to maximum of five (=best possible), to be completed by the investigator that performed the cystoscopy
Time frame: follow up immediately after procedure
Procedure time
Procedure time in minutes
Time frame: follow up immediately after procedure
Patient Tolerance
Patient tolerance to the procedure measured by 10-points visual analogue scale (VAS) after the flexible cystoscopy. VAS from 0= minimum discomfort and 10=maximum discomfort.
Time frame: follow up immediately after procedure
Adverse events
Adverse events evaluation during and immediately after procedure
Time frame: follow up immediately after procedure
Adverse events
Adverse events from discharge up to 7 days post-procedure (follow-up call)
Time frame: follow-up at 7 days after procedure
