Summary:Precise renal puncture is an essential but challenging step for successful percutaneous nephrolithotomy. We evaluated the efficiency of a novel real-time navigation system using Mixed Reality(MR) technology for human phantom kidney puncture. One human kidney phantom underwent MR-assisted percutaneous collecting system puncture. Two punctures were performed by each of 6 surgeons in the randomize selected upper, middle or lower calyces. Outcome measurements were the number of attempts for renal puncture, the time needed to evaluate the trajectory and to perform percutaneous puncture. A total of 12 punctures were performed successfully using MR-Assisted Guidance. Median evaluation time and renal puncture time for the selected calyces was 13 (range 11 to 19) and 19 seconds (range 15 to 44), respectively. One or Two attempts were needed to achieve a successful renal puncture for all of the surgeons. The proposed MR-assisted guidance solution for renal collecting system puncture proved to be accurate, simple and qu
