Evaluation of pelvic floor muscle cross-sectional area using a 3D computer model based on MRI in women with and without prolapse.

摘要

Continence and pelvic organ support depend on the interaction between muscles and endopelvic fascia [1]. Alterations in pelvic floor muscle morphology and function have been associated with parity, age and the presence of pelvic organ prolapse (POP) [1-4]. Recent advances in imaging technology and computer models have improved the assessment of pelvic floor structures [5]. This study was designed to evaluate (not to predict) the pelvic floor muscle cross-sectional area (CSA) in women with and without prolapse using a new technique based on a 3D computer model, contributing to a better understanding of the mechanism of prolapse. The advantage of using the present 3D model is the fact that any CSA can be calculated.
