Design outcomes

Primary

Measure	Time frame
Fluoroscopy imaging time between two groups ; images; short film and continuous film. Timepoint: Fluoroscopic time assessment during surgery, encompassing both the initial positioning phase and the operative procedure itself, is crucial. Pre-operative fluoroscopy helps confirm stone location and plan the nephrostomy tract. Intraoperative fluoroscopy guides access to and removal of the stone. Method of measurement: timer and The Siemens (Healthcare GmbH, 2016) imaging device fluoroscopy timer.	—
