METHODS: 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.
FINDINGS: 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.
INTERPRETATION: 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.
