Abstract:

Studies on the occurrence and development of pelvic organ prolapse (POP) was mostly based on gross anatomy and physical examination, but studies on patients are not thorough enough. In the process of disease diagnosis and treatment, surgeons′ experience and subjective judgment results played an important role on the development and implementation of surgical program, which lacked objective data as support. Magnetic resonance imaging (MRI) has the unique advantage of high-resolution pelvic floor structure, which can distinguish various support structures of pelvic floor organs and quantitatively analyze. Different levels of vaginal support structures of POP patients are studied according to the results. The weak parts of pelvic floor are judged. And then, an individualized surgical plan for the weak parts is made. It is of great significance to improve the orientation of pelvic floor reconstruction surgery and reduce the recurrence rate. We can realize the desire of minimally invasive surgery, anatomical reduction and functional recovery and minimize the occurrence of surgical complications. In addition, MRI can evaluate the quality of surgery and predict the recurrence of surgery.
