Brief Summary
This is a pilot study to (1) evaluate the effect of Ketorolac on inflammatory response and its impact on stent related symptoms in patients undergoing stent placement procedure and (2) assess feasibility of recruitment, randomization, assessment procedures and implementation of the study intervention.

Outcome Measures
Primary Outcomes (3)
Analog Pain Scale, 0 - 10 rating of pain - Stent insertion Day 1
The Analog Pain Scale is a patient reported scale from 0-10 that will be administered after standard surgical procedure of ureteroscopy with or without laser lithotripsy and/or stone extraction). The Analog Pain Scale uses 0 (zero) to describe no pain and 10 will reference worst pain.
Stent insertion Day 1
Analog Pain Scale, 0 - 10 rating of pain - Stent removal
The Analog Pain Scale is a patient reported scale from 0-10 that will be administered during the stent removal visit. The Analog Pain Scale uses 0 (zero) to describe no pain and 10 will reference worst pain.
Stent removal visit (Approximately 7 to 14 days)
Analog Pain Scale, 0 - 10 rating of pain - Follow-up Visit
The Analog Pain Scale is a patient reported scale from 0-10 that will be administered during follow up visit. The Analog Pain Scale uses 0 (zero) to describe no pain and 10 will reference worst pain.
1 to 2 months post stent removal
Study Arms (2)
Intervention Group - Ketorlac (NSAID)
ACTIVE COMPARATORSubjects will receive a one-time intravenous injection of 1 ml of Ketorlac 30 mg/ml prior to the start of the ureteroscopic procedure. After consent and during screening visit demographic information, medical/surgical history, and height and weight will be collected. On Day 0 subject will be randomized to NSAID or Saline using inclusion/exclusion criteria and the procedure data will be collected. On Day 1 subject will receive a follow up phone call and complete AUA Symptom Score, USS Questionnaire 1 and USS Questionnaire 2 and any adverse events will be assessed. These questionnaires will again be administered on the day of stent removal and again 1 to 2 months post stent removal.
Placebo Group - Normal Saline
PLACEBO COMPARATORSubjects in the control group will receive a one-time 1 ml of 0.9% injectable normal saline prior to the start of the ureteroscopic procedure. After consent and during screening visit demographic information, medical/surgical history, and height and weight will be collected. On Day 0 subject will be randomized to NSAID or Saline using inclusion/exclusion criteria and the procedure data will be collected. On Day 1 subject will receive a follow up phone call and complete AUA Symptom Score, USS Questionnaire 1 and USS Questionnaire 2 and any adverse events will be assessed. These questionnaires will again be administered on the day of stent removal and again 1 to 2 months post stent removal.
Interventions
Subjects in the control group will receive 1 ml of 0.9% injectable normal saline prior to the start of the ureteroscopic procedure.
Subjects in the intervention group will receive intravenous injection of 1 ml of Ketorlac 30 mg/ml prior to the start of the ureteroscopic procedure.
Eligibility Criteria
You may qualify if:
- Over 18 years of age and willing and able to provide informed consent
- Patients with renal urolithiasis planning to undergo ureteral stent placement following ureteroscopic manipulation
You may not qualify if:
- Patients requiring a bilateral stone procedure.
- Patients on a chronic non-steroidal anti-inflammatory drugs (NSAIDs) including Aspirin defined as any NSAIDs use for more than fifteen days within thirty days prior to the procedure. Exception: use of daily Aspirin 81 mg is allowed.
- Patients on any steroid therapy.
- Patients with prescription anti-inflammatory drugs.
- Patients with gastrointestinal ulcers.
- Patients with ureteral obstruction or stricture unrelated to stone disease.
- Patients with active urinary tract infection as evidence of untreated positive urine culture obtained prior to the procedure (as part of pre-operative testing).
- Patients with preexisting indwelling ureteral stent
- Patients who are pregnant or lactating.
- Patients with renal or liver impairment.
- Patients with concurrent disease, infection, or co-morbidity that, in the judgment of the investigator, would render the patient inappropriate for enrollment.

- Masking Details
- Prior to initiation of study enrollment, envelopes containing study randomization assignments will be created, sequentially numbered, sealed and given to the study pharmacist. Once a patient provides consent and meets study inclusion and exclusion criteria, study pharmacist will be notified of enrollment and will randomize the patient by opening the next subsequent randomization envelope.
