Tension-free vaginal tape-obturator in the treatment of stress urinary incontinence: a prospective study with five-year follow-up

Objectives

To evaluate the medium-term outcomes of using tension-free vaginal tape-obturator (TVT-O) in the treatment of patients with stress urinary incontinence (SUI).

Study design

Between December 2004 and November 2005, 103 patients with SUI were enroled and treated with TVT-O with inside-out modification. A minimum five-year follow-up (median, 65 months) was obtained from 100 patients (99.6%). Preoperative and postoperative evaluations were performed for all patients. The objective success rate of the TVT-O procedure was evaluated by a negative stress test. The secondary outcomes measured included one- and five-year subjective success rates, together with the pre- and post-operative urodynamic parameters, complications, quality of life (QOL) analysis, and patient satisfaction.

Results

Among the 103 patients, 18 (17.4%) had postoperative voiding difficulties and needed urethral bladder catheterization for various periods. After the TVT-O procedure, complete disappearance of SUI occurred in 87.4% of patients, while improvement was found in about 92%. In addition, there was no difference in the cure rate between year 1 and year 5 after the procedure (P > 0.05). In 90 patients, frequency and urge symptoms were significantly improved five years after the procedure (P < 0.005), and maximal flow rates were decreased (P < 0.05). However, the severity of obstructive symptoms and postvoid residual volumes at five years were not improved compared with one year after the procedure (P = 0.10 and P = 0.33 respectively). Finally, compared to pre-operation, incontinence severity degree and QOL scale scores were largely improved after the operation (P < 0.001), while no difference was found between years 1 and 5 (P = 0.11and P = 0.09 respectively).

Conclusions

Our result shows that the TVT-obturator, a novel mid-urethral sling, is a safe and effective procedure for the treatment of female SUI. Medium-term therapeutic results appear promising but further evaluation of long-term therapeutic outcomes is needed.     

Comparison between tension-free vaginal tape and transobturator tape in treating stress urinary incontinence after vaginal mesh surgery

Objective

A midurethral sling is the gold standard surgical treatment for stress urinary incontinence (SUI), however a lower success rate has been reported in the treatment of SUI after pelvic organ prolapse surgery. The aim of this study was to compare the success rates, quality of life, and complications with treatment using tension-free vaginal tape (TVT) and transobturator tape (TOT) in these patients.

Tension-free vaginal tape-obturator in the treatment of stress urinary incontinence: a prospective study with five-year follow-up

Objective

To investigate the prevalence of anal incontinence (AI) in woman with urinary incontinence (UI) and pelvic organ prolapse (POP). We also evaluated the impact on quality of life (QoL).

Study design

One hundred and ninety patients with UI or POP and 73 controls were recruited. AI was investigated by the Wexner index and the prevalence rates were obtained in all groups. Patients with AI completed the Fecal Incontinence Quality of Life questionnaire (FIQL). QoL was assessed using the Medical Outcome Study 36-item Short Form Health Survey (SF-36).

Results

AI prevalence was 40.54% in the UI group and 27.91% in the POP group (p < 0.0001). In the UI and POP groups correlations were found between the Wexner score and the domains of the FIQL and SF36.

Conclusion

The UI group had higher prevalence of AI than the other groups. The AI adversely affected the QoL of patients.     

Comparing effectiveness of combined transobturator tension-free vaginal mesh (Perigee) and transobturator tension-free vaginal tape (TVT-O) versus anterior colporrhaphy and TVT-O for associated cystocele and urodynamic stress incontinence

Objective

To evaluate the efficacy and safety of transobturator tension-free vaginal mesh (Perigee) and concomitant transobturator tension-free vaginal tape (TVT-O) for treating cystocele with urodynamic stress incontinence (UDSI).

Study design

A retrospective study of 115 patients with symptomatic stages 2-3 cystocele and UDSI who were treated with a Perigee system (Group I, n = 68) plus TVT-O procedure or traditional anterior colporrhaphy (Group II, n = 47) plus TVT-O procedure. All patients were followed up for more than one year. Objective and subjective symptoms were evaluated at one year postoperatively. Statistical analysis was performed using SPSS software.

Results

The objective cure rates for cystocele at one year were significantly higher in Group I than in Group II (98.5% and 86.9%, P = 0.018), respectively. The cure rates for UDSI in the two groups were 91.0% vs. 91.3% (P = 1.000). Symptomatic improvement of frequency was better in Group I than Group II (87.7% vs. 70.0%, P = 0.030). There were no significant differences with regard to intraoperative and postoperative complications between the two groups.

Conclusions

The combination of the Perigee system and TVT-O offers a safe and effective treatment for cystocele with UDSI and may be performed as first-line treatment.

Surgical treatment of stress urinary incontinence in women

Stress urinary incontinence is a common problem with 13.6% of women requiring surgery for it in their lifetime. Surgical treatments either create suburethral support or augment urethral closure. Colposuspensions and autologous rectus fascial slings are effective first-line surgical options. The use of midurethral tapes is currently suspended due to concerns with chronic pelvic and vaginal pain.

Transobturator tape procedure versus tension-free vaginal tape for treatment of stress urinary incontinence

Objective

To compare the efficacy and safety of the tension-free vaginal tape (TVT) and inside-out transobturator tape (TVT-O) procedures for the treatment of stress urinary incontinence (SUI).

Methods

A total of 315 women with or without concomitant pelvic organ prolapse repairs were randomly allocated to undergo a TVT or TVT-O procedure. Demographic data, intra- and postoperative complications, and surgical outcomes were analyzed.

Results

Fifteen patients were lost to follow-up. There were no significant differences in cure rates between the 2 groups at 6, 12, 24, and 36 months' follow-up. Hematomas occurred in 4 patients and there were 6 vaginal tape erosions. Urinary retention and de novo urinary urgency were similar in both groups. The operative time was significantly shorter for TVT-O than for TVT without other procedures (P < 0.001) and postoperative groin/thigh pain was higher (P < 0.05) in the TVT-O group.

Conclusion

Both techniques appear equally effective for the treatment of SUI. However, TVT-O had a shorter operative time and a higher rate of groin/thigh pain.     

Tension-free vaginal tape obturator versus Ajust adjustable single incision sling procedure in women with urodynamic stress urinary incontinence

Objective

To assess the efficacy and complications of inside-out transobturator tension-free vaginal tape (TVT-O) in comparison with a single incision sling procedure (Ajust) for the treatment of urodynamic stress urinary incontinence.

Study design

Prospective closely matched controlled study. In total, 171 patients were included in the study: 86 women underwent the TVT-O procedure, while in other 85 cases the Ajust procedure was performed. Subjective and objective cure, improvement and failure rates, mean operative time, hospital stay and incidence of complications were assessed.

Results

There was no statistically significant difference between the two groups for age, body mass index, parity, menopausal status and severity of prolapse. No major intraoperative complications occurred. There was no significant difference in the mean operative time and the duration of hospital stay between the two groups. The mean follow-up time of the study was 22.3 months (range 12–36 months). For the TVT-O group the objective cure rate was 86%, the improvement rate was 5.9% and the failure rate was 8.1%, while the subjective cure rate was 82.6%. For the Ajust group the objective cure rate was 84.7%, the improvement rate was 4.7%, 10.6% of patients showed no change in their symptoms and the subjective cure rate was 81.2%.

Conclusions

The Ajust sling procedure presents success rates, at 22 months’ mean follow up, comparable to the TVT-O method. Both techniques seem to be safe and effective for the treatment of urodynamic stress urinary incontinence.     

Comparison of retropubic and transobturator tension-free vaginal implants for the treatment of stress urinary incontinence

Objective

To compare the perioperative complications, failure rate, operating time, and length of hospital stay associated with 2 minimally invasive suburethral slings in the management of stress urinary incontinence in women.

Methods

Women diagnosed with stress urinary incontinence were treated with tension-free vaginal tape (TVT) or transobturator tape (TOT). The participants were followed for the next 2 years, with scheduled evaluations 6 weeks, then 3, 6, 12, and 24 months after surgery.

Results

Of the 104 participants, 55 were treated with TVT and 49 were treated with TOT. The condition was classified as “cured” in 81.8% of cases in the TVT group and 83.7% in the TOT group, and improvement occurred in 10.9% and 10.2% of cases, respectively. The mean operating time was shorter for patients treated with TOT than for those treated with TVT. There were no significant differences between the groups in terms of perioperative complications (abnormal voiding dysfunction, urinary infections, and de novo overactive bladder). The temporary and permanent urinary obstruction rates in the TVT group were approximately twice those in the TOT group.

Conclusion

Comparable complications and outcomes were observed with TVT and TOT. Tension-free vaginal implants are effective for the treatment of female stress urinary incontinence.     

De novo urgency after tension-free vaginal tape versus transobturator tape procedure for stress urinary incontinence

Objective

To determine the frequency of de novo urgency after tension-free vaginal tape (TVT) compared with the transobturator tape (TOT) procedure in women with stress urinary incontinence (SUI).

Study design

Prospective study of all consecutive women with urodynamically confirmed SUI undergoing anti-incontinence surgery between January 2000 and January 2008. All procedures were performed by experienced urogynaecologists well trained in TVT and TOT surgery. Assessments were carried out at 1, 6, 12 and, 36 months after surgery.

Results

The study population included 366 women (mean age 59.5 years), 243 in the TVT group and 123 in the TOT group. The groups were similar in terms of demographics, preoperative data, and cure rates. De novo urgency occurred in 13.4% of patients at 6 months after surgery, in 19.3% at 12 months, and in 22.1% at 36 months. De novo urgency was significantly more frequent in the TVT group than in the TOT group at 12 (22.2% vs 11.2%, P = 0.025), 24 (24.8% vs 12.3%, P = 0.033), and 36 (0% vs 24.7%, P = 0.034) months. Cure rates were similar in both groups. The final adjusted cure rate was 87.3% (319/366).

Conclusion

Treatment of SUI using the TOT procedure was associated with a lower rate of de novo urgency.     

Comparison of TVT and TVT-O in patients with stress urinary incontinence: Short-term cure rates and factors influencing the outcome. A prospective randomised study

Background: Recently, mid-urethral slings have been commonly used in treatment of patients with stress urinary incontinence (SUI).
Aims: To investigate tension-free vaginal tape (TVT) and tension-free obturator tape (TVT-O) for surgical treatment of SUI for cure rates (primary endpoint), complications and factors influencing cure rate (secondary endpoints).
Methods: One-hundred and sixty-four patients were included in the study ( n  = 81 for TVT, n  = 83 for TVT-O). The cure rates, complications, preoperative and postoperative urodynamic evaluation, Q-tip test, the Turkish version of Incontinence Impact Questionnaire (IIQ-7) and Urogenital Distress Inventory (UDI-6) scores were recorded. At three and 12 months, the patients were evaluated regarding outcome measures.
Results: The cure rates were similar in TVT and TVT-O groups, 88.9% versus 86.7% respectively. Mean operative time was significantly shorter in TVT-O group ( P  = 0.001). The cure rate was significantly higher in both groups in patients with urethral hypermobility when compared with those with no hypermobility ( P  = 0.001).
Conclusions: The TVT and TVT-O procedures appear to be equally effective for the treatment of SUI. Also, urethral hypermobility seems to be a factor influencing cure rate of mid-urethral slings.     

Investigation and treatment of urinary incontinence

Female urinary incontinence is a common but underreported condition. Initial investigation and treatment can in most cases be undertaken without urodynamic or other detailed tests. History by the use of validated symptom and quality of life questionnaires is key to the initial investigation. Initial treatment includes pelvic floor muscle training (PFMT) regardless of the type of incontinence; lifestyle interventions and bladder retraining, anticholinergics and serotonin/noradrenaline reuptake inhibitors (e.g. duloxetine) are also included depending on the type of symptoms. In mixed incontinence the predominant symptom should be treated first. When this initial treatment is ineffective, further investigation should be offered prior to specialised treatment. Urodynamics should be considered for all patients prior to surgery. Imaging and cystoscopy to exclude pathology, for example in elderly patients with an overactive bladder, are also necessary. Newer surgical interventions should be offered after careful consideration of the risk:benefit ratio for each individual woman and the amount of evidence that is currently available to support their use.     

Comparison of the efficacy of Burch colposuspension, pubovaginal sling, and tension-free vaginal tape for stress urinary incontinence.

OBJECTIVE: To compare the cure rate and confirm the clinical efficacy of the 3 most frequently performed surgical procedures for stress urinary incontinence (SUI). METHODS: Between January 2001 and May 2003, 92 women with SUI were randomly assigned to undergo the Burch colposuspension (n=33), pubovaginal sling (n=28), or tension-free vaginal tape (n=31) at the Department of Obstetrics and Gynecology, Yonsei Medical Center, Seoul, Korea. Patient characteristics, urodynamic study results, cure rates at 3, 6, and 12 months, and complication rates were compared using the chi2 test. RESULTS: There were no statistically significant differences in the cure rates initially, but after 12 months the cure rate of the pubovaginal sling procedure was found to be significantly higher than those of the tension-free vaginal tape or Burch colposuspension procedures. CONCLUSION: The cure rate of the pubovaginal sling procedure was significantly higher after 1 year, but no difference in efficacy was observed between the 2 other procedures. A randomized prospective study of a larger population should be conducted.     

Long-term results of tension-free vaginal tape (TVT) for the treatment of female urinary stress incontinence

OBJECTIVES: Prospective evaluation of outcome and complications over a 5-year period post-treatment of urinary stress incontinence by TVT, and comparison of our results with the reference studies. MATERIALS AND METHODS: About 94 patients were treated for urinary stress incontinence only by one TVT procedure (single surgical procedure), between April 1997 and December 1998; 68% of patients presented pure urinary stress incontinence and 32% mixed incontinence. We found also a 25.5% rate of sphincter deficiency (UCP < 20 cm H(2)O) in this cohort. Patients were evaluated after 5 years: 52 complete evaluations (clinical, flow measurement with measurement of post-mictional residue, 24h PAD-test, quality of life questionnaire), 30 complete telephone interviews, 12 lost to follow-up (2 patients deceased). RESULTS: About 87% of the patients had a 5-year follow-up. The success rate was 79.2% overall (84.5% for the pure urinary stress incontinence and 67% for the mixed incontinence cases), and 72.2% for the cases of associated sphincter deficiency. We had only a 13% rate of patients lost to follow-up. More than half of the urinary urgency cases were treated successfully, however with a less satisfactory outcome in cases of bladder instability. The urodynamic exploration appeared to reveal that TVT caused dysuria: 52% of patients had a maximum flowrate below 15 ml/s, but the quality of life was improved, with a 95% rate of satisfaction without functional problems. We observed no late complications such as vaginal erosion or rejection of the prolene; the de novo syndrome was rare, with 8.5% of urinary frequency, 6% of urinary urgency and only 5.7% of invalidating dysuria. We saw no cases of pelvic floor disease after TVT treatment. DISCUSSION: Our casuistry results are comparable with the reference studies by Scandinavian authors, Rezapour and Ulmsten, confirming the long-term success of the TVT procedure. Concerning the apparently elevated rates of post-TVT dysuria found by urodynamic exploration, a distinction has to be drawn between post-TVT urinary problems (frequent but oligosymptomatic), and true, severe dysuria (rare). However, "dysuria" in the broad sense did not affect the patients' quality of life, and is a reminder of the absolute necessity of meticulous compliance with the correct surgical techniques. CONCLUSION: Treatment of urinary incontinence by TVT is a reliable, mini-invasive, reproducible technique, almost suitable for outpatients, with no serious complications; it is inexpensive and very successful, including in complicated cases such as sphincter deficiency. All the recent data confirms, with this 5-year follow-up, that the TVT procedure is comparable to the previously gold standard, the Burch colposuspension.
