Objectives: The aim of this study is to identify risk factors for vaginal mesh exposure after mesh-augmented repair of anterior prolapse. Methods: We performed a retrospective cohort study of all patients who had mesh-augmented anterior repair by 1 surgeon between January 2007 and February 2012. Data were extracted from medical records. The primary outcome was the rate of anterior or apical vaginal mesh exposure. Both univariate and multivariate analyses were performed. Results: A total of 201 subjects were included. Themean (SD) follow-up was 14.3 (12.4) months. All cases were done using a type 1 macroporous monofilament polypropylene mesh. The overall mesh exposure rate was 8.5% (17/201). Univariate analysis showed a statistically significant positive association between exposure rates and the following risk factors: lower body mass index (BMI) (P = 0.016), menopause in combination with the use of hormone replacement therapy (P = 0.023), midline sagittal vaginal incision (compared with distal transverse incision) (P = 0.026), concurrent total hysterectomy (P G 0.001), surgery time (P = 0.002), and worse apical prolapse at baseline (P = 0.007). After multivariate analysis using logistic regression, only BMI (P G 0.001) and concomitant total hysterectomy (odds ratio, 48; P G 0.001) remained relevant. The exposure rate was 23.5% (16/68) when concomitant hysterectomy was performed compared with 0.8% (1/133) when no hysterectomy was done. Exposure rates stratified by BMI class were 12.9% (8/62) for BMI less than 25 kg/m2, 9.5% (8/84) for BMI of 25 to 29.9 kg/m2, 3.1% (1/32) for BMI of 30 to 34.9 kg/m2, and 0% (0/23) for BMI greater than or equal to 35 kg/m2. Conclusions: Concomitant total hysterectomy is an independent risk factor for mesh exposure after mesh-augmented anterior repair, whereas BMI may negatively correlate with exposure rates.
