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.

Exclusion Criteria: - Prior treatment for specified stone - Multiple stones on treatment side (even if only one is treated) - Anticoagulated or history of coagulopathy - Prior ureteral stent placement - Technical problems/impossibility of localizing the stone on the day of intervention Patients unable to give informed consent or unwilling to enroll or participate in the study will be excluded.
