3D printed model for flexible ureteroscopy training, a low-cost option for surgical training

Area of Science:

• Urology
• Medical Education
• 3D Printing Technology

Background:

• Surgical training models enhance outcomes and reduce learning curves.
• Flexible ureteroscopy (FURS) requires specialized training for proficiency.
• Developing accessible training tools is crucial for surgical education.

Purpose of the Study:

• To develop and evaluate a 3D printed model for flexible ureteroscopy (FURS) training.
• To assess the cost-effectiveness and suitability of the 3D model for surgical practice.
• To provide a realistic simulation for learning FURS techniques.

Main Methods:

• A patient-specific 3D model of the upper urinary tract was created using CT scan data.
• 3D printing was performed using an FDM-Ultimaker, with renal calyces numbered for identification.
• The model facilitated the use of flexible ureteroscopes and nitinol baskets for simulated stone removal.

Main Results:

• The 3D model was produced in 19 hours at a cost of €8.77.
• Urologists in training successfully utilized the model for ureteroscope insertion and calyceal exploration.
• The model effectively supported basket use for stone mobilization and removal.

Conclusions:

• A cost-effective, valid 3D printed model for flexible ureteroscopy training has been developed.
• This model enables trainees to acquire essential skills and confidence for real-world procedures.
• The 3D model serves as a valuable tool for advancing FURS education and practice.
