Abstract
OBJECTIVES: To identify risk factors for mesh erosion in women undergoing vaginal sling procedures for urinary incontinence with synthetic meshes, and to estimate the incidence of mesh erosion after these procedures. STUDY DESIGN: Retrospective study of women who underwent vaginal sling procedures between January 2007 and January 2013. In total, 1439 consecutive women with stress urinary incontinence were investigated. Five hundred and sixty-six (39.3%) women underwent a tension-free vaginal tape (TVT) procedure and 873 (60.7%) women underwent a transobturator tape (TOT) procedure. All procedures were performed using meshes of the same type and size. Women who experienced mesh erosion were defined as cases, and women who were not re-admitted or identified with mesh erosion during the study period were defined as controls. Demographics, operative techniques and outcomes were taken from medical records. Multivariate regression identified the odds of mesh erosion. RESULTS: Sixty-one of 1439 (4.2%) women were found to have mesh erosion in the postoperative period: 41 (67.2%) after TOT procedures and 20 (32.8%) after TVT procedures. The rate of mesh erosion was 4.7% in the TOT group and 3.5% in the TVT group, and this difference was significant (p<0.05). Mean age, body mass index, current smoking, menopausal status and diabetes mellitus were significantly higher among cases than controls. Univariate analysis showed that length of vaginal incision >2 cm, recurrent vaginal incision for postoperative complications, and previous pelvic organ prolapse or incontinence surgery were significant risk factors for erosion. Multivariate analysis demonstrated that older age, diabetes mellitus, current smoking, length of vaginal incision >2 cm, recurrent vaginal incision for postoperative complications, and previous pelvic organ prolapse or incontinence surgery were independent risk factors for mesh erosion. CONCLUSIONS: Mesh erosion following vaginal sling procedures is a frustrating complication with relatively low incidence. It was found to occur more often after TOT procedures than TVT procedures. Older age, diabetes mellitus, smoking, length of vaginal incision >2 cm, recurrent vaginal incision for postoperative complications, and previous vaginal surgery for pelvic organ prolapse or incontinence increased the risk of mesh erosion. Identification of risk factors may enable surgeons to prevent or minimize this complication.
