Study Summary
The purpose of this study is to assess the accuracy of ultrasound and traditional fluoroscopy to find the residual fragments before retrograde intrarenal surgery is complete. This would ultimately limit the need for radiation exposure and improve the quality of clinical care given to patients and healthcare teams.
Primary Outcome
The diagnostic accuracy of ultrasound and fluoroscopy will be measured in conjunction with endoscopic examination for detecting residual fragments during retrograde intrarenal surgery for renal stones treatment by the same endourologist to determine the size of the largest residual fragment, categorizing them as stone free, ≤ 2 mm, or \>2 mm, and compared with routine low-dose non-contrast computed tomography by a radiologist blinded to surgery and intraoperative imaging, categorizing them as st
