Although transvaginal mesh (TVM) repair is no longer used in some countries, long-term outcomes after TVM surgery are of great importance globally. However, reports with follow-up >10 years are limited. Thus, this study aimed to report outcomes in a prospective cohort with at least 10 years of follow-up. Women with stage III-IV symptomatic prolapse were approached consecutively from 2008 to 2013 at one tertiary hospital. The main outcome measure was symptomatic failure. Secondary outcomes included anatomic failure, recurrence, patient satisfaction, complications, and reoperation. The Kaplan-Meier curve was used to estimate the cumulative failure rate. Of the 121 patients enrolled in the study, 103 (85.1%) completed a median follow-up of 11 years. The estimated probability rates of symptomatic and anatomic failure were 17.6% and 8.8% in 11 years, respectively. The estimated incidence of symptomatic failure increased by 8.2% between 5 and 11 years; however, the corresponding rate for anatomic failure was 3.7%. The most common complication was vaginal mesh exposure, and its estimated probability increased from 19.3% to 28.4% from 5 to 11 years, respectively. Office trimming resolved 80.0% of vaginal exposures. These patients did not report decreased overall satisfaction. Patients with vaginal mesh exposure requiring>3 office procedures or mesh removal in the operating room (5.8% by 11 years) had lower satisfaction rates (P<0.01) and were defined as having severe mesh exposure. The rates of postoperative pain, reoperation, and Patient Global Impression of Improvement ⩾2 were 2.5%, 3.3%, and 94.2%, respectively. The results of this study implied that TVM treatment gradually increased the symptomatic failure rate but provided durable anatomical support of the vaginal wall. Vaginal mesh exposure was common in women who were largely not sexually active; however, 80% of the cases could be managed in the outpatient clinic, which did not affect patient satisfaction.
