What is being measured

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

  1. Maximum Pain Intensity Score

    Patient self-reported maximum pain intensity score measured by the Visual Analogue Scale (VAS) rated from 0-10, where 0 was no pain and 10 was the worst pain imaginable.

    Measured: postoperative Day 3

Secondary outcomes (3)
  1. Postoperative Rescue Narcotic Use

    The number of subjects who required rescue narcotic use post ureteroscopy

    Measured: postoperative Day 3

  2. Total Urinary Symptoms Score

    Patient self-reported urinary symptoms measured by the Ureteric Stent Symptoms Questionnaire (USSQ) urinary symptoms section. Following insertion of the stents, subjects were asked to answer 11 questions regarding their urinary symptoms. 9 questions used a score of 1 to 5, where 1 was never and 5 was all of the time. 1 question used a score of 1 to 4, where 1 was do not see any blood and 4 was urine is heavily blood stained. 1 question used a score of 1 to 7, where 1 was delighted and 7 was terrible. Total sum of all 11 questions for a total score ranging from 11 - 56, lower scores reflected fewer symptoms and higher satisfaction where higher scores reflected more symptoms and less satisfaction.

    Measured: postoperative day 1 and postoperative day 3

  3. The Number of Subjects With Adverse Events

    The count of subjects who experienced adverse events

    Measured: 3 days post-ureteroscopy

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Cannabidiol in people with Urinary Stone, run by Mayo Clinic at 1 site in United States.

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 6 inclusion and 9 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 18 Jan 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 18 Jan 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Maximum Pain Intensity Score (time frame: postoperative Day 3). 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 18 Jan 2023.
