The POP-Q (pelvic organ prolapse quantitative examination), also known as the Bump POP-Q scale, is named after Professor Bump, the chair of the International Conti2nence Society (ICS) Section on Pelvic Organ Prolapse and Pelvic Floor Dysfunction. Because of its objectivity, meticulousness, proven reliability and reproducibility, it was accepted by ICS in 1995, and accepted and recommended for clinical and scientific use by the American Gynecologic Urological Society and the Society of Gynecologists in 1996, and has become the most widely used prolapse evaluation system abroad. The POP-Q method has good reliability and repeatability, and is more objective and detailed. For patients with POP-Q stage III-IV, pelvic floor reconstruction is performed. The indications for surgery are clear. For cases with minor prolapse but serious symptoms, the importance of symptoms was emphasized. The symptoms such as the lack of obvious prolapse of the mass, but the sensation of falling and pressure when walking or standing, sexual discomfort, difficulty in urination and defecation, urinary incontinence, lumbar and abdominal discomfort, chronic pelvic pain, etc., were understood according to the overall pelvic theory and the “butterfly effect” in the chaos theory. ” understanding of pelvic floor changes, for patients with POP-Q stage II, comprehensive analysis of the condition, choose surgery.
