Introduction and hypothesis: We evaluated changes in voiding function at 3 months after laparoscopic sacrocolpopexy (LSC) for advanced pelvic organ prolapse (POP) patients and identified risk predictors for postoperative voiding dysfunction.Methods: Seventy-six patients with advanced POP who underwent LSC were enrolled in this retrospective cohort study. Pre- and postoperative objective voiding function was assessed by uroflowmetry plus postvoid residual (PVR) volumes. Voiding dysfunction was defined as a maximum flow rate (Qmax) < 15 ml/s, average flow rate (Qave) < 10 ml/s, or PVR > 50 ml. Statistical analyses were performed using paired-sample<italic> t</italic> tests, McNemar’s tests, and multivariate regression analyses.Results: Thirty patients (39%) showed evidence of voiding dysfunction preoperatively, but two thirds of these patients were asymptomatic. Voiding dysfunction decreased significantly from baseline to 3 months after surgery (39% vs. 21%, <italic>p</italic> = 0.009), including a decrease among patients with Qave < 10 ml/s (32% vs. 17%, <italic>p</italic> = 0.043) and PVR > 50 ml (24% vs. 9%, <italic>p</italic> = 0.019). Voiding difficulty decreased significantly from baseline to 3 months after surgery (32% vs. 9%, <italic>p</italic> < 0.001); urgency and urinary incontinence symptoms did not exhibit significant improvement (<italic>p</italic> > 0.05). Multivariate analysis identified Qave < 10 ml/s as the independent predictor of postoperative voiding dysfunction [<italic>p</italic> = 0.014, odds ratio (OR) = 4.77, 95% confidence interval (CI) 1.37-16.54].Conclusions: Preoperative voiding dysfunction is common among patients with POP and significantly improves at 3 months following LSC. A preoperative Qave < 10 ml/s was an independent risk factor for postoperative voiding dysfunction.
