Study Summary
The purpose of the study is to compare the effects, good and/or bad, of a treatment for removing kidney stones called the SURE procedure for stone evacuation to the standard treatment using a basket for stone removal.
Primary Outcome
The primary efficacy endpoint is the SFR, where stone free status is defined as zero residual fragments at 30 days observed on non-contrast CT (NCCT) (1.25mm slice thickness) by blinded central reviewer(s). The SFR is calculated by determining the number of subjects in each treatment arm with a stone free status of zero fragments and dividing that by the total number of subjects treated in the respective treatment arm.
