Brief Summary
A double blind randomized controlled trial designed to compare pain control and safety with ketorolac and oxycodone in the post-operative setting for patients undergoing ureteroscopy for treatment of urinary stones. Patients are followed for five days after their surgery as they record their pain scores, medication utilization, and stent related symptoms.

Limitations and Caveats
This study has limitations: medication adherence and symptom scores relied on self-reporting; some patients had early stent removal or were lost to follow-up; the population excluded sicker patients; and most were Caucasian at a tertiary center, limiting generalizability.
