Unveiling the depths of pelvic organ prolapse: From risk factors to therapeutic methods (Review).

Pelvic organ prolapse (POP) is a condition where one or more pelvic organs (such as the uterus, bladder and rectum) descend from their normal anatomical positions into the vagina, primarily due to the weakening of the pelvic floor support structures. While not life-threatening, POP can substantially diminish the patient's quality of life and lead to serious social and psychological complications. Researchers have explored novel directions regarding the etiology, mechanism and treatment of POP. However, existing literature on the subject often lacks comprehensive and systematic overviews. To address this gap and enhance researchers' understanding of POP, the present study reviewed the risk factors and molecular mechanisms of POP [including matrix metalloproteinases (MMPs) and tissue inhibitors of MMPs, transforming growth factor β, advanced glycation end products (AGEs)/receptor for AGE, phosphoinositide 3-kinase/protein kinase B, fibulin, lysyl oxidase-like 1, homeobox A11, collagen α-1 (XVIII) chain, Wnt signaling pathways and estrogen receptor α], as well as therapeutic approaches, such as lifestyle interventions, physical methods, pharmacotherapy, stem cell transplantation and surgical techniques. The present review aims to provide new insights for future research and contribute to the advancement of diagnosis and treatment strategies for POP.
