OBJECTIVE: To present an ex-vivo bovine model for retrograde intrarenal surgery (RIRS) training.
MATERIALS AND METHODS: The model was specifically developed for a pre-congress course organized as part of the National Pediatric Urology Congress. The course involved a 2-day online theoretical segment followed by hands-on training. Bovine kidneys were chosen for their anatomical resemblance to human kidneys. The kidneys were sourced from a local slaughterhouse, ensuring the intactness of the pelvis, ureters, and perirenal fat. A Modified Larssen solution was used for tissue preservation. The tissue was positioned within a cardboard box, with specific preparation techniques to ensure realism. During the hands-on training, participants utilized a flexible ureterorenoscope for practice. After the course, participants completed an 18-question survey assessing the model and training experience.
RESULTS: Twenty-four participants completed the training and survey. Four out of 8 procured kidneys were suitable. The model's cost was 18 euros. Around 87.5% of participants reported increased RIRS confidence. Those with prior course experience rated the model's anatomical resemblance higher (P = .016). No significant difference was observed in feedback on the model's durability or tactile feedback based on prior experience (P >.05).
CONCLUSION: The ex-vivo bovine model provides a promising alternative for RIRS training. While further studies are needed to validate its widespread application, initial feedback suggests it offers a balance between cost-effectiveness and realistic training experience.
