Shockwave lithotripsy (SWL) is a safe, non-invasive treatment for renal calculi. During SWL energy is focused on in order to break kidney stones and this energy can be varied in size from a narrow (or small) focal zone to a wide (or large) focal zone. This is a multi-centered, randomized study comparing the single treatment success rates of narrow and wide focal zones during SWL.
