Utilizing the Ex-Vivo Bovine Model in Retrograde Intrarenal Surgery Training.

Area of Science:

• Urology
• Surgical Education
• Medical Simulation

Background:

• Retrograde intrarenal surgery (RIRS) requires specialized training.
• Existing training models may lack realism or be cost-prohibitive.
• There is a need for accessible, effective simulation tools for RIRS.

Purpose of the Study:

• To develop and evaluate an ex-vivo bovine kidney model for retrograde intrarenal surgery (RIRS) training.
• To assess the model's effectiveness and realism in a hands-on training course.

Main Methods:

• An ex-vivo bovine kidney model was created using kidneys sourced from a local slaughterhouse.
• Bovine kidneys were preserved and prepared to mimic human anatomy for RIRS practice.
• Participants used flexible ureterorenoscopes on the model during a training course.
• A survey assessed participant feedback on the model and training experience.

Main Results:

• The bovine kidney model was cost-effective at 18 euros per unit.
• Approximately 87.5% of participants reported increased confidence in RIRS after training.
• Participants with prior experience rated the anatomical resemblance higher (P = .016).

Conclusions:

• The ex-vivo bovine model offers a promising, realistic, and cost-effective option for RIRS training.
• Initial feedback indicates a positive impact on surgeon confidence and skill acquisition.
• Further validation is recommended for broader application in surgical education.
