The goal of this study was to analyze the risk factors associated with vaginal erosion after synthetic sling procedure for stress urinary incontinence. Follow-up evaluations were at 1 week, 1 to 3 months, 6 months, and annually after the operation. The evaluations included detailed history taking, vaginal examinations, and perineal ultrasonographic urethrocystography. The vaginal erosion rate (6/239) after the synthetic sling procedure was 2.5%. We assessed the relationship between clinical features and vaginal erosion. Of these, only diabetes mellitus (DM) was a significant risk factor for vaginal erosion. Women with DM were 8.3 times more at risk than women without DM for developing vaginal erosion after synthetic sling procedure (p < 0.05). The vaginal erosion-free rate during the 24-month follow-up decreased significantly in women with DM. The rate of vaginal erosion associated with type III multifilamentous polypropylene sling (intravaginal slingplasty) is 10.7% more than that with type I monofilament polypropylene sling (such as tension-free vaginal tape and inside out transobturator vaginal tape) (p = 0.054). Women with DM should be informed that vaginal erosion is a possible complication after synthetic sling procedure.
