Introduction
Stress urinary incontinence (SUI) continues to impact the lives of millions of women globally, even after surgical treatment. A recent longitudinal study reveals crucial insights into what causes recurrence years after the seemingly successful application of tension free vaginal tape obturator (TVT-O).

Key Findings at a Glance
In this 4-year follow-up study conducted at Valladolid University Clinical Hospital in Spain, researchers found that:
- 11.3% of women experienced a recurrence of SUI.
- Advanced age, macrosomic delivery history, and mixed urinary incontinence (MUI) were identified as significant independent risk factors.
- Patients with ≥2 macrosomic deliveries had a 50% recurrence rate.
- Women with MUI showed a 19.5% recurrence rate, while those with pure SUI did not relapse.

What is Stress Urinary Incontinence SUI
SUI is defined as the involuntary leakage of urine during physical exertion, coughing, or sneezing. Common treatments range from pelvic floor muscle training to surgical interventions like the TVT-O, a gold-standard solution supported by European guidelines.
How Does Recurrence Happen
Despite the success of TVT-O, recurrence is not uncommon. This study shows:
- Older women may face recurrence due to weakened pelvic musculature.
- Macrosomic deliveries (>4kg babies) are associated with long term pelvic floor damage.
- Mixed incontinence reflects complex dysfunction, making these patients prone to relapse.
Clinical Implications & Counseling
Understanding the risk profile is critical for preoperative counseling. While TVT-O remains effective:
- Women with MUI or history of large births should be informed of potential mid-term relapse.
- Surgeons may consider adjunct therapies like pelvic floor rehab or lifestyle interventions for these at-risk groups.
