This study introduces a mathematical model for the lower urinary tract, aiding understanding of its complex function. The model accurately simulates healthy and neurologically impaired patients, offering a basis for artificial control systems.
Area of Science:
- Biomedical Engineering
- Urology
- Computational Biology
Background:
- The lower urinary tract is a complex biological system involving fluid dynamics and muscular control.
- Voluntary and involuntary neural systems manage its intricate functions.
Purpose of the Study:
- To propose a mathematical model of the lower urinary tract for better functional understanding.
- To establish a foundation for developing artificial control systems for the lower urinary tract.
Main Methods:
- Development of a mathematical model representing the lower urinary tract's mechanical and neural components.
- Simulation of the model to analyze the voiding process.
Main Results:
- The mathematical model accurately reproduced experimental data.
- Simulations showed urodynamic curves similar to clinical data for both healthy and neurologically impaired patients.
Conclusions:
- The proposed mathematical model effectively captures lower urinary tract function.
- The model shows potential for simulating various patient conditions and aiding in artificial control system development.
