Subjects 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.
