What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
KetorolacDrug
Also called Toradol, Acular
90 mg ketorolac in 1 L of normal saline infused at 40-120 mL/hr for 18.5-23 hours beginning 0.5 hours after the end of surgery.
PlaceboDrug
1 L of normal saline infused at 40-120 mL/hr for 18.5-23 hours beginning 0.5 hours after the end of surgery.
| Study group | Role | What they receive |
|---|---|---|
| Ketorolac | Experimental | 90 mg ketorolac in 1 L of normal saline infused at 40-120 mL/hr for 18.5-23 hours beginning 0.5 hours after the end of surgery. Receives: Drug: Ketorolac |
| Placebo | Placebo comparator | 1 L of normal saline infused at 40-120 mL/hr for 18.5-23 hours beginning 0.5 hours after the end of surgery. Receives: Drug: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Pain 'Right Now'
Visual analog scale score for pain on a scale from 0 = None to 10 = Worst.
Measured: 24 hours after the end of surgery
Morphine Equivalents of Concomitant Pain Medication
The morphine equivalent is a unit of measure to compare the efficacy of different types of opioids (narcotics). The patients were allowed to take additional pain medication in addition to either study drug or placebo. This outcome measure reports the amount of morphine (in mg) equivalent to the amount of concomitant pain medication used by the patient.
Measured: 24 hours after the end of surgery

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Ketorolac in people with Renal Calculus and Kidney Stones, 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 1 inclusion and 10 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 27 Jan 2012. 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 phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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 27 Jan 2012). 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?
Pain 'Right Now' (time frame: 24 hours after the end of surgery). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00765128, which also lists 2 linked publications.
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 27 Jan 2012; AzTrials last refreshed its copy on 7 Nov 2026.
