- Abstract
Objective: To update a previously published systematic review and perform a meta-analysis on the risk factors for primary pelvic organ prolapse and prolapse recurrence., Data Sources: PubMed and Embase were systematically searched. We searched from July 1, 2014 until July 5, 2021. The previous search was from inception until August 4, 2014., Study Eligibility Criteria: Randomized controlled trials and cross-sectional and cohort studies conducted in the Western developed countries that reported on multivariable analysis of risk factors for primary prolapse or prolapse recurrence were included. The definition of prolapse was based on anatomic references, and prolapse recurrence was defined as anatomic recurrence after native tissue repair. Studies on prolapse recurrence with a median follow-up of ≥1 year after surgery were included., Methods: Quality assessment was performed with the Newcastle-Ottawa Scale. Data from the previous review and this review were combined into forest plots, and meta-analyses were performed where possible. If the data could not be pooled, "confirmed risk factors" were identified if ≥2 studies reported a significant association in multivariable analysis., Results: After screening, 14 additional studies were selected-8 on the risk factors for primary prolapse and 6 on prolapse recurrence. Combined with the results from the previous review, 27 studies met the inclusion criteria, representing the data of 47,429 women. Not all studies could be pooled because of heterogeneity. Meta-analyses showed that birthweight (n=3, odds ratio, 1.04; 95% confidence interval, 1.02-1.06), age (n=3, odds ratio, 1.34; 95% confidence interval, 1.23-1.47), body mass index (n=2, odds ratio, 1.75; 95% confidence interval, 1.17-2.62), and levator defect (n=2, odds ratio, 3.99; 95% confidence interval, 2.57-6.18) are statistically significant risk factors, and cesarean delivery (n=2, pooled odds ratio, 0.08; 95% confidence interval, 0.03-0.20) and smoking (n=3, odds ratio, 0.59; 95% confidence interval, 0.46-0.75) are protective factors for primary prolapse. Parity, vaginal delivery, and levator hiatal area are identified as "confirmed risk factors." For prolapse recurrence, preoperative prolapse stage (n=5, odds ratio, 2.68; 95% confidence interval, 1.93-3.73) and age (n=2, odds ratio, 3.48; 95% confidence interval, 1.99-6.08) are statistically significant risk factors., Conclusion: Vaginal delivery, parity, birthweight, age, body mass index, levator defect, and levator hiatal area are risk factors, and cesarean delivery and smoking are protective factors for primary prolapse. Preoperative prolapse stage and younger age are risk factors for prolapse recurrence after native tissue surgery., (Copyright © 2022 The Author(s). Published by Elsevier Inc. All rights reserved.)
