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

Objective: To 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.

Design: Retrospective cohort study.

Setting: Multicentre study including 19 units in Norway.

Population: Women undergoing TVT surgery for stress urinary incontinence (SUI) during 2001-2006 (20-year cohort) and 2011-2012 (10-year cohort).

Methods: The 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 Measures: Subjective 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).

Results: In 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).

Conclusions: Tension-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.
