Long-term outcomes for transobturator tension-free vaginal tapes in women with urodynamic mixed urinary incontinence.Neurourol Urodyn. 2017 04; 36(4):902-908.NU
To assess the long-term patient reported outcomes following transobturator tension-free vaginal tapes (TO-TVT) in women with urodynamic mixed urinary incontinence (MUI).
A secondary analysis of the 9-year follow-up of the E-TOT study: 341 women with predominant stress urinary incontinence symptoms were randomized to undergo either inside-out or outside-in TO-TVT between April 2005 and April 2007. Forty-eight women had preoperative urodynamic MUI and were available for 9-year follow-up. Primary outcome was the patient-reported success rate defined as very/much improved on Patient's Global Impression of Improvement PGI-I. Secondary outcomes included impact on women's quality of life, sexual function, overactive bladder symptoms,and late adverse events. Statistical analysis was performed using SPSS v.23.
Forty-eight women completed the 9-year follow-up, with adjusted response rate of 63%. The success based on the PGI-I was 64.6% (n = 31), with a further 14.6% (n = 7) who reported "improved." There was no significant difference between groups (OR 1.11; 95%CI 0.33, 3.70; P > 0.999). Clinically significant improvement in quality of life was found in 85.3%. Cure of urgency and UUI was reported by 35% and 41%, whereas worsening was reported in 6.5% and 2.3%, respectively. One patient reported chronic groin/leg pain. The small sample size and the sizeable loss to follow-up are limitations in this study.
This is the first study to report the long-term outcomes of TO-TVT in women with urodynamic MUI; TO-TVT is associated with a good and sustained patient-reported success rate in women with MUI up to 9-years follow-up.
