Construction and application of urinary system model with functional bladder module.

Area of Science:

• Biomedical Engineering
• Urology
• Medical Simulation

Background:

• The urinary system, particularly the bladder, presents complex physiological functions crucial for diagnosis and treatment.
• Developing accurate and functional models is essential for advancing medical education and research.

Purpose of the Study:

• To design, construct, and evaluate a functional bladder module for the urinary system model.
• To assess the model's performance in simulating bladder pressure, capacity, and detrusor activity.
• To explore the model's utility in enhancing medical staff's understanding and basic operating skills.

Main Methods:

• Design and fabrication of a bladder model using selected materials.
• Performance analysis including pressure, safety capacity, and detrusor characteristics.
• Comparative analysis with urodynamic test data and between normal and obstruction model groups.

Main Results:

• The bladder model exhibited significant differences compared to urodynamic tests in pressure performance and safety capacity (P < 0.01).
• Detrusor workmanship in the model showed significant differences between normal and obstruction groups (P < 0.01).
• Significant differences in detrusor contraction rate were observed between normal and obstruction groups at a specific time point (t3).

Conclusions:

• The constructed bladder model effectively enhances the understanding of urinary system functions.
• The model serves as a valuable tool for improving the basic operating skills of medical staff.
• Despite identified limitations, the bladder model provides a useful experimental reference for future clinical bladder research.
