Visually navigated, ultrasound-guided, freehand percutaneous calyceal puncture – preclinical evaluation of a novel device to simplify a complex surgical task

Abstract

Purpose Freehand sonographic percutaneous puncture techniques for the renal calyceal system are on the rise. Much time and practice are required to master this technique. Navigation-supported puncture aids could help make percutaneous access easier and faster. The aim of this study was to determine whether navigated puncture is feasible, and whether it is easier and faster compared to the conventional sonographic procedure.
