摘要

Aim

To create an accessible, low-cost, high-fidelity and reusable laparoscopic pyeloplasty model that provides realistic simulation, allowing trainees and surgeons to practice transferable skills in laparoscopic pyeloplasty.

Methods

Development process involved an extensive literature review, research on suitable materials, consultation with expert urologists, and iterative prototyping. Soft tissue-mimicking material (PlatSil Gel – Silicone Rubber) and 3D printing technology were used to replicate the features of dismembered pyeloplasty. A modular design approach was adopted to allow reusability. The model was tested at the BAPES Advanced 3 mm Minimal Invasive Surgery (MIS) course in March 2024. Face validity, content validity, and acceptability were assessed through a 5-point Likert scale questionnaire.

Results

The model successfully replicated the essential anatomical features and key surgical steps encountered during laparoscopic pyeloplasty. It received a mean score of 4 SD ± 0.63 for realism and a mean content validity of 4.75 SD ± 0.20. Additionally, 100% of the trainees accepted the model as good or excellent for practising the procedure (mean score 4.72 SD ± 0.30). The cost of the materials for the complete model is £16.72, while the pelvis-ureter replacement is £1.63.

Conclusions

The model demonstrated to be a low-cost, high-fidelity and sustainable training tool, providing a platform for trainees/surgeons to practice the key surgical steps of laparoscopic dismembered pyeloplasty, leading to improved confidence. Further validation studies and integration of feedback from trainees and experienced surgeons are essential for optimizing the model for widespread adoption in urology training programs.
