Patients who are being consented to undergo a ureteroscopy with the PI will be asked to participate in this study. There is currently no consensus on standard of care regarding intraoperative analgesia for ureteroscopy. There is wide variability in practice, some clinicians choose to administer intraoperative analgesia while others rely only on the sedation effects of general anesthesia. This study is being carried out to see if administration of Ketorolac during ureteroscopy provides a post-operative benefit in pain scores when compared to no treatment.
