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.

Arm Intervention/treatment
Active Comparator: Oxycodone group
Patients randomized to 20 pills of 5 mg oxycodone by mouth every 6 hours as needed for pain after ureteroscopy.
Drug: Oxycodone
5 mg of oxycodone taken by mouth every 6 hours for 5 days

Experimental: Ketorolac group
Patients randomized to 20 pills of 10 mg ketorolac by mouth every 6 hours as needed for pain after ureteroscopy.
Drug: Ketorolac
10 mg of ketorolac taken by mouth every 6 hours for 5 days

Primary Outcome Measures :
  1. Visual Analog Pain Score [ Time Frame: Daily for 5 days ]
    Averaged pain score over five days post-operatively (measured 0 to 10 mm)

Secondary Outcome Measures :
  1. Ureteric Stent Symptom Questionnaire [ Time Frame: Post-operative days 1 and 5 ]
    A validated assessment tool for stent-related symptoms and their impact on patient quality of life

  2. Medication Adverse Effects [ Time Frame: Daily for 5 days ]
    Patient-reported medication related side effects

Other Outcome Measures:
  1. Pain Medication utilization [ Time Frame: Daily for 5 days ]
    Blinded study drug daily usage or alternative over the counter pain medication utilization. Additionally the proportion of patients in each group who utilized the provided "rescue" oxycodone pills.

  2. Healthcare contact regarding refractory pain [ Time Frame: Up to Two months post-op ]
    Occurrence of contacting healthcare professionals through a phone call, office visit, physician message or emergency room visit regarding refractory pain.
