Abstract: Female pelvic floor dysfunction(PFD) is a common gynecological disease. Its clinical manifestations include stress urinary incontinence (SUI), pelvic organ prolapse (POP) and female sexual dysfunction (FSD), which seriously affect the health and quality of life of middle-aged and elderly women. In recent years, most countries in the world have begun to pay attention to this disease, and China has made the prevention of women′s PFD as a main task of the government. Its pathogenesis has not been unified, and the diagnosis is mostly based on the patient′s symptoms. Biomechanics, which was first used in orthopedics and plastic surgery, is gradually applied to the field of obstetrics and gynecology. The application of biomechanical methods provides a new reference standard for the pathogenesis, clinical diagnosis, treatment selection and efficacy evaluation of PFD. Especially, vaginal tactile imaging (VTI) can show vaginal wall pressure visually. It is a new and precise evaluation technique of pelvic floor biomechanics. This paper summarized the application and prospect of biomechanics in PFD.
