Brief Summary:
A comparison on the outcomes of patients undergoing shockwave lithotripsy using the Storz machine versus the Dornier machine.

Condition or disease Intervention/treatment Phase
Kidney Stone Kidney Calculi Ureteral Calculi Ureterolithiasis Urolithiasis Procedure: Lithotripter Not Applicable

Detailed Description:
This is a single institution, prospective randomized controlled clinical trial comparing two lithotriper machines (the Storz Modulith LX-F2 and Dornier Delta III) in patients who are undergoing shockwave lithotripsy (SWL) as the primary management of their urinary stone. Patients record pain score on day of operation and post-operative day 1, and are followed for 1 month until they receive standard of care imaging at 1 month post-operatively.
