Rates of subjective and objective cure, satisfaction, and pain 10–20 years after tension‐free vaginal tape (TVT) surgery: A retrospective cohort study

Abstract

AbstractObjectiveTo evaluate rates of subjective and objective cure, treatment satisfaction, pain, and the correlation between cure and body mass index (BMI), at 10 and 20 years after tension‐free vaginal tape (TVT) surgery.DesignRetrospective cohort study.SettingMulticentre study including 19 units in Norway.PopulationWomen undergoing TVT surgery for stress urinary incontinence (SUI) during 2001–2006 (20‐year cohort) and 2011–2012 (10‐year cohort).MethodsThe Norwegian Female Incontinence Registry was used to identify women eligible for the study, who answered validated questionnaires about urinary incontinence, pain and satisfaction.Main outcome measuresSubjective cure of SUI (with stress index of <3, range 0–12), objective cure (<3 g on stress test) and persisting pain and satisfaction after TVT (scored on a five‐point Likert scale).ResultsIn total, 1210 of 1903 (64%) patients responded. The subjective cure rate was 68% after 10 years, versus 59% after 20 years, and did not significantly differ after adjusting for age, BMI, parity and preoperative stress index (adjusted OR 1.27, 95% CI 0.82–1.94). The objective cure rate was 100% versus 93% (P < 0.001), with 89% versus 76% reporting subjective satisfaction (P < 0.001), and with 4.7% versus 2.7% reporting persisting pain (P < 0.001), after 10 versus 20 years, respectively. Women in obesity classes I and II, compared with women of normal weight, had an increased risk of not being subjectively cured (crude OR 2.02, 95% CI 1.42–2.90; OR 2.95, 95% CI 1.60–5.46, respectively).ConclusionsTension‐free vaginal tape (TVT) provided high rates of subjective and objective cure at 10 and 20 years after surgery, with no significant difference between the two cohorts. Although 3%–5% of women experienced persisting pain, most women were satisfied with TVT surgery. Obesity was associated with a lower cure rate.
