Virtual reality (VR) simulation training significantly improved novice endoscopists' basic skills in genitourinary procedures. The trained group showed enhanced performance compared to the control group, suggesting VR’s value in surgical education.

Area of Science:

  • Medical Education
  • Surgical Simulation
  • Urology

Background:

  • Novice endoscopists require effective training methods for basic endoscopic skills.
  • Virtual reality (VR) simulators offer a promising tool for surgical training.

Purpose of the Study:

  • To assess the impact of supervised training with a VR genitourinary endoscopy simulator on novice endoscopists' skills.
  • To compare the effectiveness of VR simulation training against standard practice.

Main Methods:

  • 21 medical students underwent pre- and post-testing on a VR simulator for procedures like cystoscopy and ureteroscopy.
  • Participants were randomized into a control group (no training) or a training group (five supervised VR sessions).
  • Objective VR parameters and global rating scales by experienced evaluators were used for assessment.

Main Results:

  • The trained group showed statistically significant improvements in total procedure time, guidewire insertion time, self-evaluation, and evaluator assessment.
  • Post-test scores revealed significantly better task performance, overall performance, and total evaluator scores in the trained group compared to the control group.
  • No significant improvements were observed in the control group.

Conclusions:

  • Supervised VR simulation training leads to significant skill improvement in novice endoscopists.
  • VR simulation effectively enhances the performance of basic endourologic tasks.
  • VR training may translate to improved real-world surgical performance.
