Summary
A new low-fidelity simulation model for vesicovaginal fistula (VVF) repair effectively trains fistula identification and closure. This tool addresses limited surgical training opportunities for VVF repair, enhancing surgeon skills.
Area of Science:
- Urology
- Surgical Education
- Gynecology
Background:
- Limited training opportunities exist for surgeons specializing in vesicovaginal fistula (VVF) repair.
- Skilled surgeons are crucial for successful VVF repair outcomes.
Purpose of the Study:
- To develop a low-fidelity simulation model for transvaginal VVF repair.
- To identify and validate the essential steps in VVF repair.
- To assess the simulation model's fidelity in replicating these steps.
Main Methods:
- A low-fidelity simulation model for transvaginal VVF repair was designed and constructed.
- Hierarchical task analysis and a modified Delphi process involving urogynecologic surgeons identified essential repair steps.
- The model's ability to replicate these steps was evaluated by a separate group of surgeons using a postsimulation questionnaire.
Main Results:
- The simulation model successfully replicated tasks related to fistula identification and closure.
- Surgeons validated the essential steps of transvaginal VVF repair through consensus.
- The model's fidelity in replicating cystoscopy or bladder filling steps was not confirmed.
Conclusions:
- A novel, low-fidelity simulation model for transvaginal VVF repair was successfully developed.
- The model demonstrates effectiveness in simulating critical steps of fistula identification and closure.
- This simulation offers a valuable tool to enhance surgical training for VVF repair.
