Pelvic organ prolapse is the protrusion of the pelvic organs and their adjacent vaginal walls into or out of the vagina. Common pelvic organ prolapse includes uterine prolapse, rectal bulge, bladder bulge and pelvic floor prolapse. Common risk factors for POP are as follows: 1. Age: Many domestic and international studies have shown that the prevalence of POP increases with age; 2. Pregnancy and childbirth injuries: Especially vaginal delivery with forceps or difficult fetal suction may cause the pelvic fascia, main uterus, sacral ligaments and pelvic floor muscles to be stretched excessively and weaken their supporting force, making POP prone to occur; 3. Chronic increase in abdominal pressure: For example, chronic cough, fluid accumulation in the abdomen, frequent heavy lifting or constipation, etc. resulting in increased intra-abdominal pressure can lead to the occurrence of POP; 4, obesity: may cause or aggravate POP, while body size is also considered to be a contributing factor to prolapse; 5, history of pelvic surgery: pelvic surgery can disrupt the normal anatomy of the urinary bladder and cause peripheral nerve damage, leading to the occurrence of pelvic floor dysfunction; 6, menopause and low estrogen levels. Postmenopausal hormonal changes also play an important role in the occurrence of prolapse, but there is still no evidence that estrogen supplementation therapy can prevent the occurrence of POP; 7. Environment and individual lifestyle: can have an impact on the prolapse of pelvic organs.
