Towards a better understanding of pelvic system disorders using numerical simulation.

Area of Science:

• Biomedical Engineering
• Pelvic Floor Disorders
• Computational Anatomy

Background:

• Pelvic organ prolapse (POP) is a common condition characterized by hyper-mobility of pelvic organs.
• The exact pathophysiology and origins of POP remain poorly understood.
• Existing knowledge gaps hinder the development of effective prevention and treatment strategies.

Purpose of the Study:

• To virtually recreate the biomechanical pathology of POP using numerical simulation.
• To enhance the understanding of the multifactorial origins of pelvic organ prolapse.
• To validate a computational model against in-vivo dynamic MRI observations.

Main Methods:

• Development of a finite element model based on MRI data from a healthy female subject.
• Incorporation of mechanical interactions between pelvic organs, including contacts, ligaments, and adhesions.
• Validation of the model by comparing simulated functional mobilities with dynamic MRI data.
• Step-by-step modification of the model to simulate pathologic conditions.

Main Results:

• The computational model successfully replicated functional pelvic system dynamics observed in dynamic MRI.
• Numerical experiments provided insights into the biomechanical processes contributing to POP.
• The simulation results reinforce existing clinical hypotheses regarding the multifactorial etiology of POP.

Conclusions:

• Virtual biomechanical simulation is a valuable tool for investigating the pathophysiology of pelvic organ prolapse.
• The study supports the hypothesis that POP arises from multiple contributing factors.
• Further refinement of computational models can deepen our understanding and potentially guide clinical interventions for POP.
