Abstract
Objective. To evaluate the efficacy of the tension-free vaginal tape operation (TVT) in patients with and without previous anti-incontinence surgery. Design. Prospective follow-up study. Setting. University hospital in Finland. Population. A total of 130 women who had a TVT procedure from August 1998 to December 2002. Main outcome measures. Subjective cure, complications and voiding symptoms. Methods. Sixty women with recurrent (group A) and 70 women with primary stress urinary incontinence (SUI) (group B) were compared. One follow-up visit took place two months postoperatively and a questionnaire-based evaluation was carried out three years after operation. Further information was collected a mean of eight years after the operation. Results. There was no difference in the transient postoperative retention rate (17 vs. 19%, p = 0.78) and number of complications (20 vs. 13%, p = 0.29) between group A and group B. At two months after operation, 85% of patients in group A and 94% in group B were cured of SUI and were satisfied with the operative result (p = 0.096). The satisfaction rates at three years were 86 and 91% in groups A and B, respectively, and cure rate of SUI was 93% in both groups. At follow-up, 20% of the patients in group A and 5.7% in group B (p = 0.013) had de novo urge symptoms and the rate of voiding difficulties increased especially in group B women over time. Conclusions. TVT results in the same cure and complication rates when performed for primary SUI and recurrent SUI. The procedure is effective and associated with a low and acceptable level of complications. It is well suited to treat also recurrent SUI.
