Area of Science:

  • Urology
  • Surgical Skills Assessment
  • Medical Simulation

Background:

  • Microsurgical varicocelectomy requires specialized technical skills.
  • Objective assessment tools are needed to evaluate proficiency in this procedure.

Purpose of the Study:

  • To develop and validate a task-specific checklist (TSC) for microsurgical varicocelectomy.
  • To assess the reliability and validity of the TSC in differentiating skill levels.

Main Methods:

  • A 4-item TSC was developed and validated by 14 urology judges.
  • 12 participants (experts and novices) performed the procedure on a simulation model.
  • Performance was filmed and evaluated by blinded raters using the TSC.

Main Results:

  • The TSC achieved content validity after reformulation based on judge feedback.
  • The TSC demonstrated construct validity, differentiating between expert and novice performance.
  • High inter-rater reliability was observed.
  • Experts completed the simulation significantly faster than novices (201 vs. 496 seconds, p=0.01).

Conclusions:

  • The developed task-specific checklist is a reliable and valid instrument for assessing microsurgical varicocelectomy skills.
  • The TSC can differentiate skill levels and aid in surgical training and evaluation.
