Abstract
Introduction and hypothesis
This is a randomized multicenter study comparing two mid-urethra tape procedures, the tension-free vaginal tape (TVT) with the tension-free vaginal tape-obturator (TVT-O) in terms of cure rate and complication rate.
Methods
Seven Finnish hospitals participated. Power calculations required 130 women in each group to detect a 10% difference in cure rate. A total of 267 underwent the allocated operation. Follow-up was scheduled at 2, 12, 36 and 60 months. A cough stress test was used as an objective outcome measure. Subjective outcome was assessed by five different condition-specific quality of life questionnaires.
Results
At 36 months of follow-up, 96% of the patients were evaluated. Objective cure rate was 94.6% in the TVT group and 89.5% in the TVT-O group (p = 0.131). Subjective cure rates were significant with no difference between the groups.
Conclusion
The TVT and the TVT-O are equally effective in the treatment of stress urinary incontinence after 36-month follow-up with no difference in complication rates.
