The review protocol was prospectively registered on the Open Science Framework (OSF; DOI: 10.17605/OSF.IO/W8CYR). Random-effects models were applied to estimate pooled incidence, with subgroup analyses by procedure and POUR definition. Associated factors were synthesized narratively.Results: Thirty-four studies including 20,466 patients were analyzed. The pooled incidence of POUR was 16.1% (95% CI 12.8– 20.1; I2 = 97.3%). Incidence was highest after pelvic organ prolapse surgery (30.9%) and sling/mid-urethral sling procedures (25.3%), and lowest after minimally invasive benign hysterectomy (3.7%). Increased risk was associated with baseline voiding dysfunction, diabetes mellitus, vaginal surgical approach, and opioid exposure, while minimally invasive techniques and selected perioperative strategies were protective.Conclusion: POUR is a common, procedure-dependent complication of gynecologic surgery. Procedure-specific risk stratification and standardized perioperative pathways are needed to reduce POUR and improve postoperative recovery.Keywords: postoperative urinary retention, gynecologic surgery, incidence, risk factors, meta-analysis
