We included longitudinal observational studies (prospective or retrospective) and randomized controlled trials (RCTs). Data were extracted with risk-of-bias assessment with the Cochrane Risk of Bias tool and the Risk of Bias in Nonrandomized Studies of Interventions tool. Extractions were reviewed by a second researcher. We conducted restricted maximum-likelihood meta-analyses of effect sizes as feasible.\nTABULATION, INTEGRATION, AND RESULTS:\nOne RCT and six cohort studies met the inclusion criteria. The overall quality of the studies was fair to good. The incidence of persistent pelvic pain after hysterectomy ranged widely, from 12% to 68%. Younger age was associated with increased likelihood of persistent pain after hysterectomy (summary odds ratio [OR] 1.39, 95% CI, 1.11–1.75; five studies, N=11,165). Ovarian conservation was not significantly associated with persistent pain (OR 2.04, 95% CI, 0.67–6.18; three studies). Endometriosis was variably associated with persistent pain, with two studies finding an association (summary OR 1.18, 95% CI, 1.06–1.31), whereas two other studies found that stage III or greater endometriosis was not associated with persistent pain (summary OR 0.99, 95% CI, 0.45–2.21). Multiple predictors of interest were evaluated by single studies, limiting the ability to draw aggregate conclusions.\nCONCLUSION:\nHigh proportions of patients undergoing hysterectomy for chronic pelvic pain experience persistent postoperative pain. Although there is heterogeneity among study design and clinical factors examined and some associations should be interpreted with caution, persistent pelvic pain was associated with younger age at the time of hysterectomy.\nSYSTEMATIC REVIEW REGISTRATION:\nPROSPERO, CRD42024530836.","source_license":"public-domain-us","license_restricted":false}
