4-year recurrence risk factors after tension-free vaginal tape-obturator as a treatment of stress urinary incontinence

Objetive: The objective is to identify factors associated with the risk of recurrence of stress urinary incontinence at 4years, after surgical treatment with transobturator suburethral tape. Methods: A prospective four-year follow-up observational study (2015-2019, n=341) was performed in women who underwent SUI using the tension-free vaginal tape-obturator. The sample was 71 patients with recurrence of SUI. Statistics: T-Test or U-Mann and ROC for quantitative variables, Chi-Square and OR for qualitative variables. Results: The frecuency of SUI recidive was 11.27% (8 patients). Of all the variables analyzed, they only showed a significant association with the SUI recurrence: age, fetal macrosomia and mixed urinary incontinence. The frequency of recurrence in case mixed incontinence amounted to 19.5%, if the patient had 1 delivery >4 kg to 22% and if the antecedent was ≥2 macrosomal deliveries it increased up to 50%. Conclusion: Advanced age, macrosomic delivery and mixed urinary incontinence have shown a significant association with the risk of relapse of SUI after tension-free vaginal tape-obturator at 4 years. Therefore, it would be necessary to inform them of a greater risk of failure in the medium term in the preoperative interview.
