Surgical treatment of stress urinary incontinence using the tension-free vaginal tape-obturator system (TVT-O) technique

OBJECTIVE: The purpose of the research was to provide a review of the efficacy of the TVT-O technique for the surgical treatment of stress urinary incontinence (SUI) and to assess surgical and postsurgical complications related to this technique. STUDY DESIGN: An initial assessment was carried out on 44 women who underwent TVT-O surgery between 16 September 2004 and 1 February 2005. The follow-ups after 3 and 12 months were attended by 37 and 35 patients, respectively. All 44 patients were included for the statistical estimation of intra- and postoperative complications, whereas improvement in the quality of life was assessed only in those patients who came for a follow-up visit. To assess the efficacy of the treatment, the participants were surveyed using the King questionnaire on the day preceding surgery and during a follow-up visit 3 and 12 months after surgery. The participants whose scores from the two questionnaires changed > or =90% were deemed to be cured. A considerable improvement in quality of life was recorded when the score was 89-75%. With scores of 74-50%, there was a reduction in SI symptoms. However, when the score was 50-0%, no improvement in quality of life was reported, and in participants with scores <0% the quality of life deteriorated. Statistical analysis was carried out using the Statistical Package for Social Sciences (SPSS) V. 10.0, with the Spearman correlation and Chi-squared tests. The results were considered statistically significant when P<0.05. RESULTS: After 12 months, total cure was achieved in 15 participants (42.8%), significant improvement was noted in 6 (17.1%), SUI symptoms abated in 4 (11.4%), no improvement was noted in 7 (20%), and quality of life deteriorated in 3 (8.7%). CONCLUSION: TVT-O surgery is an efficient and reasonably safe method of SUI treatment in women. The ease of use, short duration of surgery and hospitalisation, minor postsurgical discomfort and a small proportion of complications make this method acceptable to patients. With regard to the results of treatment, additional patients should be analysed for a longer period of time.     

Monarc vs TVT-O for the treatment of primary stress incontinence: a randomized study

The aim of the study was to compare the efficacy and complications of the Transobturator tape (Monarc) vs the tension-free vaginal tape obturator (TVT-O) in women with urodynamic stress incontinence. A prospective, randomized study was conducted. One-hundred and twenty patients were included in the study, and 114 of them were available at 12 months follow-up. Sixty-one patients were subjected to the TVT-O procedure and 53 to the Monarc procedure. Subjective and objective cure and improvement rate and complications incidence were assessed. The objective cure rate was 87% for the TVT-O procedure and 90% for the Monarc group. The subjective cure rate was 80% for the TVT-O group and 77% for the Monarc group. The improvement was 13 and 11.5% for the TVT-O and Monarc groups, respectively. There was one accidental injury to the urethra with the Monarc technique. The Monarc technique presents success rates and complications comparable to the TVT-O method at 1 year follow-up.

Surgical treatment for female stress urinary incontinence: what is the gold-standard procedure?

In the last few years, the Burch colposuspension and the fascial slings were often defined from the pages of the most relevant journals of general medicine, as gold-standard procedures for the surgical treatment of stress urinary incontinence (SUI), whereas mid-urethral slings (tension-free vaginal tape (TVT) and tension-free vaginal tape obturator) were attributed a marginal and almost experimental role in this field. This poorly reflect the current scenario of the surgical management of SUI: Recently, a number of meta-analysis have demonstrated that TVT is significantly more effective if compared to colposuspension and that it is followed by significantly lower perioperative morbidity if compared to pubovaginal slings. It is not realistic to suggest to general practitioners that the surgical gold standard for SUI includes the performance of a wide laparotomy, long hospital stays and a high risk of long-lasting intermittent self-catheterisation. This would inevitably discourage women from embarking on surgical treatment, which instead could actually improve their quality of life.     

Different sling procedures for stress urinary incontinence: A lesson from 453 patients

Several midurethral sling (MUS) procedures, such as tension-free vaginal tape (TVT), TVT obturator (TVT-O), tension-free vaginal tape SECUR (TVT-S), and pubovaginal sling (PVS), have been used for the treatment of female stress urinary incontinence (SUI); however, which method is best for a particular patient group is not known. This study aimed to identify the best rationale for choosing the optimal MUS procedure for each patient. In total, 453 consecutive female patients with SUI who were treated with MUSs in West China Hospital of Sichuan University from September 2003 to September 2011 were enrolled in this study. All the patients underwent comprehensive pre-, intra-, and postoperative evaluations, including collection of demographic information, pelvic examination, and urodynamic testing, and operation-related complications were recorded. The Incontinence Quality of Life questionnaire was also completed. Under local or general anesthesia, 105 cases were treated with TVT, 243 with TVT-O, 90 with TVT-S, and 15 with PVS. Patients with different profiles in terms of age, symptom duration, concomitant procedures, urodynamic parameters, and pelvic organ prolapse (POP) quantification score were treated successfully; the body mass index did not differ significantly among the various treatment options. The cure and improvement rates were similar among the treatment groups: 97.14% (102/105) in TVT, 100% (243/243) in TVT-O, 98.89% (89/90) in TVT-S, and 100% (15/15) in PVS. Only minor complications were experienced by the patients. In conclusion, each MUS procedure was observed to be safe and effective in different subpopulations of patients, and the results suggest that appropriate patient selection is crucial for the success of each MUS procedure.
