Summary

Urological trainees show superior spatial awareness skills compared to consultants and controls using virtual reality testing. This suggests innate spatial ability may not be a key factor in selecting surgical trainees.

Area of Science:

  • Surgical Education
  • Medical Simulation
  • Spatial Cognition

Background:

  • Urological surgeons require spatial awareness for complex procedures.
  • Current selection methods for urological trainees prioritize academic achievement over surgical aptitude.
  • The role of innate spatial awareness in surgical skill acquisition is not fully understood.

Purpose of the Study:

  • To compare innate spatial awareness skills between consultant urologists, urological trainees, and non-surgeon controls.
  • To evaluate the utility of the Minimally Invasive Surgical Trainer-Virtual Reality (MIST-VR) system for aptitude testing in urological trainees.

Main Methods:

  • 122 volunteers (39 consultants, 46 trainees, 37 controls) were tested using the MIST-VR system.
  • Performance was assessed on time, errors, economy of movement, and diathermy accuracy in three tasks.

  • Demographic data including experience and visual/manual laterality were recorded.

    • Main Results:

    • Urological trainees demonstrated significantly better performance than controls in Task 1 (fewer errors, greater economy of movement).
    • Trainees outperformed both consultants and controls in Task 2 (faster, more economical movement).
    • In Task 3, trainees showed superior results in errors, economy of movement, and diathermy usage compared to consultants; controls performed similarly to consultants.

    Conclusions:

    • Urologists do not exhibit innate spatial ability distinct from the general population.
    • Urological trainees outperformed experienced consultants in virtual reality spatial awareness tasks.
    • The MIST-VR system is not suitable for aptitude testing but may aid in laparoscopic surgical training; other psychometric factors may be more critical for surgical skill acquisition.
