Abstract
BACKGROUND: Tension free vaginal tape (TVT) has proven to be successful. Nevertheless, complications of the TVT have been reported. The aim of this study was to describe factors that might influence the efficacy and safety of the TVT procedure in our clinic. METHODS: Medical records of all patients who underwent TVT surgery between 1 January 2001 and 1 May 2004 were reviewed. To achieve subjective follow-up, in 2004 and 2005, we sent all patients standardised validated questionnaires. Data were analysed with SPSS. RESULTS: A total of 198 TVT procedures were performed. In 75 cases (37.9%), the procedure was combined with vaginal prolapse surgery. Complications were found in 19.7% of all TVT procedures. Most patients (71%) returned the questionnaire. Median follow-up was 27 months (range: 9-49). Subjective success rate was 73%. Logistic regression analysis showed that success rate of the TVT procedure was not influenced by any of the factors we studied. Complications were not more common in patients who had undergone prior incontinence or prolapse surgery. Concomitant prolapse surgery with the TVT, however, was found to be the only risk factor for complications, mainly prolonged catheterisation. CONCLUSIONS: In this study, we found no factor that influenced the success rate of the TVT. In the literature, the experience of the surgeon is marked as a factor influencing the success rate. We, therefore, gradually reduced the number of gynecologists who perform TVT. Concomitant prolapse surgery, however, was shown to be an independent risk factor for complications. Therefore, we prefer to 'separate' prolapse and incontinence surgery.
