Escalating, Constant and Reduction Energy Output in SWL for Renal Stones

Escalating SW amplitude treatment protocols have been shown to be safe on long-term with less harm to kidney tissue. This clinical trial will be conducted at a tertiary care university hospital. All patients referred to the SWL unit will be evaluated for eligibility to be randomized. Randomization process "complete" or "unrestricted" randomization was used to allocate patients to the three arms of the clinical trial where one patient was randomly assigned to one of the three arms blindly.
