Systematic review and meta-analysis of the pelvic organ prolapse and vaginal prolapse among the global population

Pelvic organ prolapse (POP) occurs when one or more pelvic organs (uterus, bowel, bladder or top of the vagina) descend from their normal position and bulge into the vagina. Symptoms include pelvic discomfort, fullness, and changes in bladder or bowel function. Treatment ranges from conservative approaches to surgery, depending on symptom severity. Surgical methods include vaginal wall repair, with or without hysterectomy, or via laparoscopic, robotic or open techniques. Common complications include bleeding, infection, and urinary or bowel dysfunction. A systematic review was conducted, and a protocol was registered with PROSPERO (CRD42022346051). Publications from 30 April 1980 to 30 April 2023 were retrieved from multiple databases. Data were analysed using random-effects and common-effects models with subgroup and sensitivity analyses. Forty-four studies met the inclusion criteria, with 29 studies used for meta-analysis of vaginal prolapse surgery outcomes. Sixteen studies focused on patients who had undergone hysterectomy alongside prolapse repair. Patients who underwent vaginal prolapse surgery with hysterectomy experienced higher operative and postoperative complication rates than those without hysterectomy. Increased risks included hospital readmission, POP recurrence and re-operation. The review highlighted a lack of diversity in terms of ethnicity, age and comorbidity status, which are essential to fully understanding the impact of POP. Future research should focus on these underrepresented factors. [Abstract copyright: © 2024 The Author(s). BJUI Compass published by John Wiley & Sons Ltd on behalf of BJU International Company.]
