Changes in Voiding Function after Transvaginal Mesh Repair for Advanced Anterior Vaginal Prolapse

Abstract Objective This study evaluated changes in voiding function at 3 months and 1 year after transvaginal mesh (TVM) repair in women with advanced anterior vaginal prolapse (AVP) and identified predictive risk factors of postoperative voiding dysfunction (PVD). Study design Women with stage≥3 AVP who underwent TVM repair surgery were included in this retrospective cohort study. Voiding dysfunction was defined as an average flow rate (Qave)＜10 ml/s, a maximum flow rate (Qmax)＜15 ml/s, or a postvoid residual volume (PVR)＞50 ml. Pre- and postoperative voiding function was assessed by uroflowmetry, PVR examination, and the Urinary Distress Inventory-6 (UDI-6) and the Urinary Impact Questionnaire-7 (UIQ-7). Statistical analyses were performed using paired-sample t tests, χ2 tests, and multivariate logistic regression. Results Sixty-two women were included in this study, uroflowmetry data were available for 35 of them at 1-year follow-up. Forty-three percent of women showed evidence of voiding dysfunction preoperatively. The PVR decreased significantly from baseline to 1 year postoperatively (17.97 ± 38.48 vs. 0.00 ± 0.00, p  Conclusion Nearly half of the patients had advanced AVP accompanied by preoperative voiding dysfunction. Improvement in voiding function was observed at 3 months and could last for one year postoperatively.
