About this study

Official title: Clinical Investigation to Evaluate the Performance and Safety of Ambu® aScope™ 4 Cysto and aView™ Urologia for Flexible Cystoscopy

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.

Read the detailed description

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.

Being tested
Flexible cystoscopy
Medical subject headings
Lower Urinary Tract Symptoms, Urinary Bladder Diseases

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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)

    Measured: follow up immediately after procedure

Secondary outcomes (5)
  1. 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

    Measured: follow up immediately after procedure

  2. Procedure time

    Procedure time in minutes

    Measured: follow up immediately after procedure

  3. 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.

    Measured: follow up immediately after procedure

  4. Adverse events

    Adverse events evaluation during and immediately after procedure

    Measured: follow up immediately after procedure

  5. Adverse events

    Adverse events from discharge up to 7 days post-procedure (follow-up call)

    Measured: follow-up at 7 days after procedure

Questions about this trial

What is this clinical trial studying?

A study testing Flexible cystoscopy in people with Cystoscope and Lower Urinary Tract Symptoms, run by Ambu A/S at 2 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 Oct 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Denmark, Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Performance of the cystoscope (time frame: follow up immediately after procedure). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Oct 2021.
