A Study to Compare ShockPulse-SE vs. Trilogy Lithotripters for Removal of Large Kidney Stones

Overview

About this study

The purpose of this study is to measure how well two different devices work to break up and remove kidney stones. We are comparing a newer device to an older one to see which one is faster at breaking up kidney stones. We hypothesize that the Trilogy device will increase the stone clearance rate by 25% compared to the Shockpulse-SE device.
