Background
Tension‐free vaginal tape obturator (TVT‐O) and tension‐free vaginal tape secur (TVT‐S) are common surgeries for the treatment of stress urinary incontinence (SUI), several randomised controlled trials (RCTs) have compared the effects of TVT‐O and TVT‐S, yet the results remained inconsistent. Therefore, we attempted to conduct this systematic review and meta‐analysis to analyse the role of TVT‐O and TVT‐S in patients with SUI.
Methods
We searched PubMed databases from inception date to Jan 15, 2020 for RCTs that compared TVT‐O and TVT‐S in SUI patients. Two authors independently screened and extracted data from the published articles. Summary odd ratios (OR) or mean differences (MD) with 95% confidence intervals (95% CI) were calculated for each outcome by fixed‐ or random‐effects model.
Results
Seven RCTs with a total of 755 patients were identified, with 373 patients for TVT‐O and 382 patients for TVT‐S. TVT‐O preceded TVT‐S in the objective cure at 12 months (OR = 1.72, 95% CI 1.21‐2.45), subjective cure (OR = 1.98, 95% CI 1.08‐3.62); but TVT‐S have more advantage in the incidence of postoperative thigh pain (OR = 18.94, 95% CI 7.01‐51.15); no significant differences on the duration of operative procedure (OR = −1.09, 95% CI −2.37‐0.18), urinary retention (OR = 0.77, 95% CI 0.36‐1.62) and urinary infection (OR = 1.80, 95% CI 0.63‐5.13) were found.
Conclusions
TVT‐O should be preferred for patients with SUI even though with higher risks of postoperative thigh pain when compared with TVT‐S, more related studies are needed to identify the role of TVT‐O and TVT‐S for the treatment of SUI.
