Female postpartum pelvic floor dysfunction disease|(PFD) is a series of diseases caused by pelvic floor injury, defects, and dysfunction. The disease mainly includes pelvic organ prolapse (POP) and stress urinary incontinence (SUI). Although PFD is not fatal, it can seriously affect
the quality of life of patients. For this reason, women need to repair the pelvic floor muscles after childbirth. In this study, we used a new polypropylene mesh biomaterial implanted into the vagina and then repaired the pelvic floor and observed its repair effect. Pathological tests proved
that the new biological material caused certain acute inflammatory reactions after implantation in the vagina, which increased the number of collagen cells in the pelvic floor muscle and restored its function.
