Insights into Biomechanics of Pelvic Organs: A 3D Finite Element Analysis Investigating Vaginal Vault Prolapse Mechanisms and Surgical Intervention

Abstract

Pelvic Floor Disorders (PFDs), including Vaginal Vault Prolapse (VVP), pose significant health concerns for women, affecting urinary, rectal, and sexual functions. This study addresses the lack of understanding in prolapse mechanisms and pelvic organ dynamics through a precise 3D Finite Element Analysis (FEA) model. Developed with data from the visible human project, this model integrates diverse material properties, ensuring accurate representation of pelvic organ behavior. Investigating nine simulated cases, the study unveils subtle variations in pelvic dynamics, emphasizing the link between changes in pelvic organ stiffness and prolapse. A simulated surgical Y-mesh demonstrates efficacy in rectifying VVP and pelvic floor issues. This research contributes substantially to VVP biomechanics, emphasizing the integral nature of pelvic organ interactions and urging further exploration of long-term surgical effects. The model not only enriches discussions on women's health but also lays the groundwork for advanced models to understand and manage Vaginal Vault Prolapse
