PCA competency of each participant was assessed objectively by performing task 4 on the PERC Mentor™ simulator, where they had to correctly access and pop 7 balloons in 7 different renal calyces and subjectively by the validated Percutaneous Nephrolithotomy-Global Rating Scale (PCNL-GRS).


 The PCNL-GRS in combination with the PERC Mentor™ simulator was able to differentiate between competent and non-competent PGTs.
