Area of Science:

  • Urology
  • Medical Simulation
  • Endourology

Background:

  • Percutaneous nephrolithotomy (PCNL) is a key procedure for large kidney stones.
  • Effective training methods, including simulation, are crucial for PCNL proficiency.
  • Evaluating new simulation platforms is essential for advancing endourologic education.

Purpose of the Study:

  • To compare the efficacy of three percutaneous nephrolithotomy (PCNL) simulation platforms.
  • To assess their suitability for teaching and evaluating percutaneous renal access skills.
  • To determine the validity of the novel Marion K181 3D immersive VR simulator.

Main Methods:

  • Urology trainees and faculty performed standardized renal access tasks on three simulators: PercMentor (VR), Cook Medical (porcine), and Marion K181 (3D VR).
  • Participants rated simulators on realism, tactile feedback, and teaching utility.
  • Performance data, including fluoroscopy time, were recorded and analyzed.

Main Results:

  • The Marion K181 simulator received higher participant ratings than the PercMentor across all domains.
  • The Marion K181's performance and utility were comparable to the porcine model, without radiation exposure.
  • Fluoroscopy time consistently correlated with participant experience across all tested platforms.

Conclusions:

  • The Marion K181 PCNL simulator offers a valid, radiation-free training alternative for percutaneous renal access.
  • It demonstrates comparable utility to porcine models as a teaching tool.
  • Further research is needed to establish its validity as an assessment tool.
