Summary
This study introduces an inexpensive ex vivo porcine kidney model for training percutaneous endourological procedures. This realistic model enhances surgical skill acquisition for various interventions, surpassing traditional non-biological simulators.
Area of Science:
- Urology
- Surgical Simulation
- Medical Education
Background:
- Percutaneous endourological procedures demand advanced surgical skills.
- Current non-biological simulators offer limited realism for training.
- Previous work developed a porcine model for ureteroscopy.
Purpose of the Study:
- To develop an advanced ex vivo model for training percutaneous endourological procedures.
- To provide a realistic and versatile training tool superior to existing methods.
Main Methods:
- A porcine kidney and ureter were dissected from the retroperitoneal package.
- The specimen was embedded in silicone for stability.
- The renal pelvis was filled with saline to simulate hydronephrosis, and stones were implanted for percutaneous nephrolithotomy training.
Main Results:
- The ex vivo model enables training of diverse percutaneous endourological procedures, including nephrostomy, lithotomy, and endopyelotomy.
- It offers superior "tissue feeling" and anatomical fidelity compared to non-biological models.
- The model is readily available and cost-effective.
Conclusions:
- This ex vivo porcine model is an effective, inexpensive, and versatile tool for training percutaneous endourological procedures.
- It significantly improves upon non-biological simulators by providing a more realistic training experience.
- Facilitates comprehensive skill development for urological interventions.
