This study aims to develop a novel low-cost synthetic gelatin model in laparoscopic ureterolithotomy training. The research focused on evaluating the model's practicality, cost-effectiveness, ease of use, anatomical realism, and its significant impact on improving trainees' surgical skills and confidence.

A laparoscopic trainer box model was developed to replicate the ureteral anatomy using a latex Penrose drain and gelatin medium to simulate the feeling of surrounding tissues. 24 participants (n=24) underwent training for laparoscopic ureterolithotomy using the model and evaluated the model’s cost-effectiveness, anatomical realism, ease of setup, compatibility with laparoscopic equipment, tissue property realism, feedback mechanism, educational value, and overall satisfaction. Data was collected through a post-training evaluation form utilizing a 1–5 Likert scale. The collected data was analyzed using descriptive statistics and thematic analysis.

Participants reported high overall satisfaction with the model. Cost-effectiveness (mean: 4.5) and ease of setup (mean: 4.42) were rated highly, while realism of anatomy representation (mean: 4.17) and tissue properties (mean: 4.0) received mixed feedback. The model's educational value and compatibility with laparoscopic instruments were well-regarded.

The gelatin-based model provides a cost-effective, accessible, and practical alternative for laparoscopic ureterolithotomy training. While overall satisfaction was high, further refinements in anatomical realism are needed to enhance its utility.
