Trial summary

Comparison of Images of the same area in the bladder in four different SPIES modalities on a tablet computer. Participants are asked to delineate the area on the image suspect for malignancy as precise as possible with a stylus on the tablet screen. Delineated area(s) is/are captured.

About this study

Comparison of Images of the same area in the bladder in four different SPIES modalities on a tablet computer. Participants are asked to delineate the area on the image suspect for malignancy as precise as possible with a stylus on the tablet screen. Delineated area(s) is/are captured. Time to start the drawing and total time per image are captured. Hereafter, an judgement of Image quality is asked on a scale of 0 to 10, 0 being worst possible and 10 being best possible.

Read the detailed description

Karl Storz Company has recently introduced the Storz Professional Image Enhancement System. To evaluate the interpretation of cystoscopy images in different SPIES modalities a tablet program was developed. Images of 20 bladder areas were captured in 4 different SPIES modalities; white light, Clara\&Chroma, Spectra A and Spectra B. Of each bladder area, one extra image was added to the program, so that a total of 100 images were interpreted.

Every image is shown 45 seconds on the tablet screen. Participants are asked to delineate with a stylus on the tablet the precise area they suspect to be malignant and would resect or treat. After they are done they go to the next slide and the time is stopped.After each image, participants are asked to judge the quality of the image on a scale of zero to ten, with zero being the worst and ten the best.After this judgement, the next image for interpretation is presented.

What is being measured

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

  1. Intra observer variability in delineated areas between the same bladder areas in different SPIES modalities.

    Measured: 1 hour

  2. Inter observer variability in delineated areas between the same bladder areas in different SPIES modalities.

    Measured: 1 hour

  3. Image quality of images in different SPIES modalities

    Measured: 1 hour

Secondary outcomes (6)
  1. Differences in time to start delineation between images in different SPIES modalities

    Measured: 1 hour

  2. Differences in time needed per image in different SPIES modalities

    Measured: 1 hour

  3. Differences in use of úndo' button between different SPIES modalities

    Measured: 1 hour

  4. Differences in participants who are familiar with image enhancement system (NBI/SPIES) vs participants who are not familiar working with them.

    Measured: 1 hour

  5. Differences in interpretation of images between participants with a visual impairment or colourblindness vs participants without.

    Measured: 1 hour

  6. Differences in interpretations between participants in age or experience in TURBT annually.

    Measured: 1 hour

Questions about this trial

What is this clinical trial studying?

An observational study of Comparison of Images of the Same Area in the Bladder in Four Different SPIES Modalities on a Tablet Computer, run by Clinical Research Office of the Endourological Society.

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 1 inclusion and 1 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 25 Jun 2014. Status can change between updates, so confirm with the study contact before making plans.

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?

Intra observer variability in delineated areas between the same bladder areas in different SPIES modalities. (time frame: 1 hour). The study lists 3 primary outcomes in all. 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 25 Jun 2014.
