Study Summary
The primary objective of this study is to compare the time to acceptable stone fragmentation during clinical use of the holmium laser when using energy settings 0.2J vs 0.8J. The hypothesis is that holmium laser energy settings 0.8J will require less time than lower energy settings 0.2J for fragmenting urinary stones. The clinical practice is to treat urinary stones until the stone is reduced to fragments ≤ 2 mm in size. This is determined by using the laser fiber which is 273 microns to visually estimate the size of the resultant fragments as described by Patel et al, J Endo 2014. Investigators will standardize the effect of stone size by creating a ratio of stone size to treatment time. In this study, the frequency is set at 15Hz. Thus, the study contains two arms: 0.2J\&15Hz, and 0.8J\&15Hz. Patients will be randomized into the two groups by the ratio of 1:1.
