TVT and Sparc suburethral slings: a case–control series

Two midurethral slings, TVT and Sparc, are the subject of this case–control series aimed at assessing sling placement, voiding function, bladder symptoms and patient satisfaction. Thirty-seven Sparc and 69 TVT patients were matched for age, body weight, pre-existing urge incontinence, preoperative voiding, concomitant surgery and length of follow-up (mean 0.6, range 0.1–1.5 years). There were no significant differences for subjective cure/improvement, satisfaction or symptoms of incontinence. The clinical stress test was positive in 8/37 Sparc vs 4/69 TVT patients (p=0.019). The TVT had a more negative effect (p=0.001) on postoperative voiding. The Sparc was situated more cranially at rest and further from the symphysis pubis, and was more mobile (p<0.001) on Valsalva. There are significant differences in medium-term outcomes after TVT and Sparc, affecting tape placement, mobility, effect on voiding function and objective stress continence. Patient satisfaction and subjective cure rates seem similar.Abbreviations TVT Tension-free vaginal tapeEditorial Comment: The authors are to be commended for performing such timely research as clinicians struggle to understand the differences, if any, among the various minimally invasive midurethral slings that have been developed since the original tension-free tape (TVT) procedure. Despite the authors proposed explanation of a pretensioning effect, without intraoperative ultrasound measurements of tape displacement before and immediately after sheath removal, several other equally plausible explanations exist. It is also interesting to note the differences in postoperative voiding parameters and objective cure rates that once again remind us of the difficulty in surgically achieving high objective cure rates for stress incontinence without compromising normal outflow during micturition.     

TVT vs Monarc: a comparative study

Following the success of the tension-free vaginal tape (TVT), there has been considerable interest in technique modifications such as the transobturator approach for implant placement. We attempted to elucidate possible anatomical and clinical differences between the two methods in a retrospective cohort study. One hundred and fourteen women who had undergone TVT or Monarc implantation were assessed by or under the supervision of the senior author, with identical tensioning technique. They were followed up by an interview, uroflowmetry, and translabial 3D ultrasound. There were significant differences for patient satisfaction (P=0.013), subjective overall cure/improvement (P=0.0018), and the symptom of poor stream (P=0.03), all favoring the Monarc group. On imaging Monarc tapes appeared more proximal at rest (P=0.006) and Valsalva (P=0.002) and remained further from the symphysis pubis on Valsalva (P=0.01). At 9 months follow-up, there was no significant difference as regards to cure rates for stress incontinence between the two suburethral slings. Monarc tapes are located more proximally and may be less obstructive, judging from a lower incidence of symptoms of voiding dysfunction. Patient satisfaction and overall subjective cure/improvement were higher after Monarc. In summary, the Monarc is an effective TVT alternative, achieving cure of stress incontinence by similar means. It may be less obstructive, resulting in improved patient satisfaction.     

A randomized controlled equivalence trial of short-term complications and efficacy of tension-free vaginal tape and suprapubic urethral support sling for treating stress incontinence

OBJECTIVE: To establish the equivalence between the tension-free vaginal tape (TVT) and the suprapubic urethral support sling (SPARC). Approximately 35% of women have stress urinary incontinence (SUI), and although TVT is now perceived as the standard treatment, the SPARC is a very similar procedure and is thought to have fewer peri-operative complications. PATIENTS AND METHODS: Patients with clinical SUI were recruited from public and private urology/urogynaecology clinics, and participated in the trial of TVT vs SPARC. The primary outcome was bladder perforation; secondary outcomes were blood loss, voiding difficulty, urgency, and cure of SUI symptoms. Sample size calculations, based on an estimated 2% perforation rate, showed that 290 patients would be needed to detect a clinically significant difference of 5%. Stratification was by previous incontinence surgery and the experience of the surgeon. RESULTS: There were 301 operations; the difference in bladder perforations was not statistically significant, at one/147 TVT (0.7%), and three/154 SPARC (1.9%), with the difference in rate of 0.013 (95% confidence interval (CI) - 0.01 to 0.04; odds ratio 2.89, 95% CI 0.30-28.21; P = 0.62), and nor were differences in estimated blood loss of >100 mL (TVT, 32/147, 21.8%; SPARC 28/154, 18.2%); de novo urgency (TVT 15/37, 40.5%; SPARC 14/33, 42.4%), objective cure (TVT 143/147, 97.3%; SPARC 148/152, 97.4%) or vaginal mesh erosion (TVT 7/147, 4.8%; SPARC 16/152, 10.5%). Acute urinary retention (TVT none of 147; SPARC 10/154, 6.5%; odds ratio infinity, 95% CI 2.2-infinity; P = 0.002) and subjective cure (TVT 128/147, 87.1%; SPARC 117/153, 76.5%; odds ratio 2.07, 95% CI 1.13-3.81; P = 0.03) were statistically significantly different. CONCLUSION: These results are consistent with clinical equivalence between TVT and SPARC for bladder perforation. There was no statistically significant difference between TVT and SPARC in blood loss, urgency or objective cure of SUI symptoms at 6 weeks. However, SPARC was more difficult to adjust correctly, and a statistically significant number of patients required loosening of the tape in theatre (P = 0.002). TVT had a lower rate of vaginal erosion and a statistically significantly higher cure rate of subjective SUI symptoms than SPARC. Overall, voiding difficulty (loosening of the tape), urgency and vaginal mesh erosion were the most important clinical problems. This trial showed the importance of testing new devices which appear to be similar, but which might have relevant differences. There was no financial assistance for this study, and a long-term follow up is planned.     

TVT versus SPARC: comparison of outcomes for two midurethral tape procedures

To compare the subjective and objective cure rates in women who underwent either the SPARC or the TVT midurethral sling for the treatment of stress urinary incontinence. This retrospective study included all 122 consecutive women undergoing a TVT or SPARC midurethral sling procedure for objective stress urinary incontinence between January 2000 and March 2003 at the Evanston Continence Center. Primary outcomes were subjective and objective stress incontinence cure rates. Subjects underwent multichannel urodynamics preoperatively and 14 weeks postoperatively, and stress testing at last follow-up. The two groups were compared using univariate and multivariate analyses. Seventy-three subjects underwent a TVT and 49 subjects had a SPARC procedure. There were no statistical differences in demographic factors between the two groups. Subjects undergoing SPARC were more likely to void by Valsalva effort. One hundred and seven women returned for objective postoperative evaluation after surgery. The TVT procedure was associated with higher subjective (86 vs. 60%, P=0.001) and objective (95 vs. 70%, P<0.001) stress incontinence cure rates. There was no difference between the TVT and SPARC groups in the resolution of subjective and objective urge urinary incontinence. TVT was associated with a higher stress urinary incontinence cure rate than SPARC in this retrospective study. As new midurethral sling products are introduced, prospective randomized controlled trials should be conducted to evaluate their relative efficacy and safety.     

Tension-free vaginal tape versus transobturator tape as surgery for stress urinary incontinence: results of a multicentre randomised trial

OBJECTIVES: This prospective, multicentre, randomised study compared the safety and success rate of tension-free vaginal tape (TVT) and transobturator tape (TOT) in treatment of female stress urinary incontinence. METHODS: Of 148 women, 73 were randomised to TVT and 75 to TOT. Preoperative workups included case history, clinical examination, Urogenital Distress Inventory and Impact Incontinence Quality of life questionnaires, 1-h pad test, pelvic ultrasound, and urodynamics. Intra- and postoperative complications were the primary end point; subjective and objective changes in SUI, and postoperative voiding dysfunctions were secondary end points. Patients were classified into two main categories: dry (no leakage during clinical and/or stress test and/or reported by patients) versus wet. Patients who referred being wet were separated into "improved" or "failure" on subjective analysis. Other outcome variables were quality of life questionnaires and VAS scale. Clinical checkups were conducted at 3, 6, 12 mo, and then annually. RESULTS: Both techniques are safe and no significant differences emerged in intra- and postoperative complications. At a mean follow-up of 31 mo, the overall objective cure (dry) was 71.4% for TVT and 77.3% for TOT (p=ns). When one considered "dry" plus "wet but improved," these values increased to 90% and 90.6%, respectively (p=ns). Median satisfaction rate was 9 (range: 1-10) for both procedures. Postoperative storage symptoms are a controversial issue; they persisted in 44% of patients in TVT group versus 24% in TOT group (p<0.053). CONCLUSIONS: TOT appears as safe and effective as TVT in surgery for female SUI, with minimal complications at mean follow-up of 31 mo.     

Does the tension‐free vaginal tape procedure (TVT) affect the voiding function over time? Pressure‐flow studies 1 year and 3½ years after TVT

AIM: The aim was to evaluate the voiding function over time after the TVT procedure for stress incontinence. MATERIALS AND METHODS: Thirty-eight women with urodynamic stress urinary incontinence were included in the study. For voiding function assessment the patients were asked if voiding had changed postoperatively, and objectively uroflowmetry, residual urine measurement and pressure-flow were performed preoperatively, 1 year and 3(1/2) years postoperatively. RESULTS: At 1/3(1/2) years follow-up 87%/69% were subjectively cured and 13%/26% improved, respectively. The objective cure rate was 89%/74%. Subjectively 77%/63% of the patients felt an altered voiding function towards more difficult voiding one and 3(1/2) years after surgery, respectively. Objectively all the uroflowmetry variables deteriorated and residual urine volume increased over time although the changes were not statistically significant between the 1 and 3(1/2) years follow-up. Pressure-flow variables were essentially unchanged. CONCLUSION: The changes in voiding function after a TVT do not reverse over time. This may imply a potential risk of development of clinically important impaired emptying function.     

The correlation between preoperative voiding mechanism and surgical outcome of the tension-free vaginal tape procedure,with reference to quality of life

OBJECTIVES: To determine whether the surgical outcome of the tension-free vaginal tape (TVT) procedure differs in patients with dysfunctional voiding (DV) or normal voiding. PATIENTS AND METHODS: The voiding mechanism and surgical efficacy of the TVT procedure were analysed retrospectively by reviewing the charts of 79 consecutive women treated over 2 years. Based on their initial voiding mechanism, the patients were divided into two groups, with or without DV. The King's Health Questionnaire was used to evaluate the women's quality of life both before and 1 year after surgery. RESULTS: The change in free maximum urinary flow rate (Qmax) after surgery differed significantly between the groups (P = 0.001). Moreover, both before and after surgery, the free Qmax was significantly lower (P = 0.019 and 0.001, respectively), and the detrusor pressure at Qmax (both P < 0.001) and urethral resistance (P = 0.036 and 0.027, respectively) significantly higher in the group with DV. The subjective outcome measure showed that the cure rates were not significantly different in the two groups (P = 0.173), but the objective outcome measure showed a significant difference (P = 0.025). Analysis of the total scores for all domains showed that significantly more women improved by> 25% in the group without than in those with DV (P = 0.016). CONCLUSIONS: The objective cure rate of the group without DV undergoing the TVT procedure was significantly higher than in those with DV. In addition, subjective measures assessed by the disease-specific quality-of-life questionnaire indicated that the group without DV had a better quality of life than those with DV.     

Prospective randomized comparison of transobturator suburethral sling (Monarc) vs suprapubic arc (Sparc) sling procedures for female urodynamic stress incontinence

The aims of this trial were to compare the attendant complications and postoperative voiding function of the Monarc and suprapubic arc (Sparc) suburethral sling procedures. This is the first article in English literature to compare different suburethral sling procedures using prosthesis of the same material and the same weave. Sixty women with urodynamic stress incontinence alone or combined with pelvic prolapse less than International Continence Society stage II were randomly allocated to either the Monarc or Sparc group. A comparison of the peri- and postoperative results comprising complications and symptoms of voiding function revealed no significant differences between the two groups in a follow‐up ranged from 6 to 14 months (median, 9 months). However, the nonsignificant increase in tendency of inadvertent vaginal perforation and disability/pain of thigh (Monarc 12.9 vs Sparc 0.0%, p=0.112 and Monarc 12.9 vs Sparc 0.0%, p=0.112, respectively) has clinical significance. Based on the analyses of the comparison of Blaivas obstruction nomograms, postoperative voiding function was not significantly different between the two surgical groups. We concluded that Monarc and Sparc suburethral taping proved to be equally safe and posed no remarkable impact on voiding function in a short term postoperative follow up. However, intraoperative urethrocystoscopy is recommended for safety in both the Monarc and Sparc procedures.This study had no conflicts of interest as regards any commercial association.     

Determinants of patient dissatisfaction after a tension-free vaginal tape procedure for urinary incontinence

PURPOSE: We identified the determinants of patient satisfaction after a tension-free vaginal tape procedure. MATERIALS AND METHODS: We retrospectively analyzed the records of 187 consecutive women with genuine stress (133) and mixed (54) incontinence. The objective cure rate was determined by clinical and urodynamic examination, and the subjective cure rate was assessed by a visual analog scale and the Contilife questionnaire. RESULTS: Mean followup was 27 months (range 6 to 34). The overall complication rate was 35.3%. The major perioperative and postoperative complications were bladder injury in 9.6% of cases, urinary retention in 6.4%, difficult voiding in 10.7% and new onset urge symptoms in 21.3%. The overall objective and subjective cure rates were 90.4% and 70.6%, respectively. The mean preoperative and postoperative visual analog scale score plus or minus standard deviation was 6.2 +/- 2.4 and 0.9 +/- 2.2, respectively (p = 0.0001). The subjective cure rate was significantly lower in women who underwent the procedure under general or spinal anesthesia than in those who received local anesthesia (p = 0.01). This difference was related to the rate of new onset urge symptoms. The mean postoperative visual analog scale score in women with and without new onset urge symptoms was 2.2 +/- 3.2 and 0.2 +/- 0.7, respectively (p = 0.0001). No difference in the subjective cure rate was detected according to patient age, menopausal status, previous incontinence surgery, the body mass index, additional procedures associated with tension-free vaginal tape surgery or the Ingelman-Sundberg classification. CONCLUSION: These results confirm that the tension-free vaginal tape procedure is associated with a high objective but lower subjective cure rate. The procedure performed using local anesthesia was associated with a lower incidence of difficult voiding and new onset urge symptoms.     

Effect of tension-free vaginal tape and TVT-obturator on lower urinary tract symptoms other than stress urinary incontinence

Variable effects on lower urinary tract symptoms (LUTS) other than stress urinary incontinence (SUI) have been reported after tension-free vaginal tape (TVT). We measured the effect of TVT on LUTS using the American Urological Association Symptom Index (AUASI). Patients undergoing TVT completed the AUASI pre- and post-operatively. Total scores (TS), storage scores (SS), and voiding scores (VS) were compared overall and among patients with SUI vs mixed urinary incontinence (MUI) and those who underwent TVT vs TVT-obturator (TVT-O). The mean change in TS and SS was −3.6 and −3.0. Mean reductions in TS and SS were significant in all patient subsets with no change in VS. There was no significant difference in the mean changes in TS between patients with SUI vs MUI or those undergoing TVT vs TVT-O. LUTS are improved after TVT in most patients. In general, voiding symptoms were not adversely affected.     

Tension-free vaginal tape and associated procedures: a case control study

OBJECTIVES: We compare objective and subjective cure rates after tension-free vaginal tape procedures performed alone or in conjunction with vaginal procedures. METHODS: One hundred eighty-six women underwent a tension-free vaginal tape procedure for stress or mixed urinary incontinence. One hundred women treated with tension-free vaginal tape alone (group 1) were compared with 40 women treated with tension-free vaginal tape and concomitant vaginal hysterectomy (group 2), and 46 patients treated with tension-free vaginal tape and pelvic floor reconstruction (group 3). Patient outcomes, surgical difficulties and complications are reported. Postoperative voiding diaries, standing stress-test results, and patient satisfaction were compared. RESULTS: There were no significant differences among the three groups in terms of age, menopausal status, BMI, previous incontinence surgery, or the type and degree of incontinence. Parity was significantly higher in the group treated with tension-free vaginal tape and pelvic floor reconstruction ( p=0.04 ). The overall perioperative complication rate was 15.6%. Women treated with tension-free vaginal tape and hysterectomy (group 2), and those treated with tension-free vaginal tape and pelvic floor reconstruction (group 3) had a significantly higher incidence of bladder injury (17.9% and 13%, respectively, versus 5% in group 1; p=0.05 ). Estimated blood loss and the frequencies of postoperative urgency and voiding disorders did differ significantly between women treated with tension-free vaginal tape alone and those who underwent associated procedures. The mean follow-up time was 24.5+/-2.6 months. No difference in the objective cure rate was found between the tension-free vaginal tape group and the other two groups (93% versus 97.5% and 91.1%; p=0.3 ). No difference in the subjective cure rate was found between the tension-free vaginal tape group and the groups undergoing associated procedures (72% versus 72.5% and 68.8%; p=0.4). CONCLUSION: Pelvic floor defects, benign uterine disorders and stress urinary incontinence can be safely treated with tension-free vaginal tape and vaginal procedures during the same surgical procedure.     

Long-term results of tension-free vaginal tape for female urinary incontinence: Follow up over 6 years

OBJECTIVE: To describe the long-term outcome of using tension-free vaginal tape (TVT) with and without associated procedures. METHODS: A questionnaire was mailed to a population of 61 women who had undergone TVT surgery more than 6 years ago. Of this population, 41 (80%) had suffered from stress urinary incontinence (SUI). The questionnaire included questions about urinary symptoms, satisfaction and quality of life. The questionnaire was answered by 51 of the 61 women. RESULTS: Mean follow up was 83 months. The women with SUI had a persistent cure rate of 80% with a satisfaction rate of 97%. The cure rate after 6 years was 37% in women with mixed incontinence. Concomitant hysterectomy (relative risks = 0.87) and body mass index (BMI) do not alter the long-term results of TVT procedure. Peroperative bladder injury is not associated with an increased risk of long-term lower urinary tract symptoms (LUTS) or with a decreased satisfaction rate (relative risks = 0.85). CONCLUSIONS: Concomitant hysterectomy, increased BMI and bladder injury do not alter good long-term results of TVT.     

Clinical and urodynamic outcomes of tension-free vaginal tape procedure

The tension--free vaginal tape procedure (TVT) has been regarded as a safe, minimally invasive method for the treatment of female stress urinary incontinence. In a prospective multicenter study we evaluated safety and efficacy of TVT procedure for the treatment of female stress incontinence. From 1998. to 2003, a total of 42 patients, mean age 60 years (range 34-76) with urodynamically verified stress urinary incontinence underwent the TVT procedure. The mean follow-up period was 28 months (range 14 to 32). Intra- and postoperative complications were few, including bladder perforations (4.7%), vaginal hematoma (2.4%), complete urinary retention (2.4%), transient urinary retention (19%) and urinary tract infection (7.1%). Postoperatively, voiding time and functional urethral length significant increased. The subjective and objective cure rates were 85.7% and 90.5%, respectively. We conclude that the TVT procedure is associated with high cure rate and low morbidity.     

The long term (5-years) objective TVT success rate does not depend on predictive factors at multivariate analysis: a multicentre retrospective study

OBJECTIVES: We evaluated the predictive risk factors that could affect the long-term efficacy of the tension-free vaginal tape (TVT) procedure for the treatment of female stress urinary incontinence (SUI). METHODS: One hundred thirty-eight (mean age, 52.4+/-9.3 yr) women who underwent the TVT procedure for SUI were selected and followed up for at least 5 yr (mean, 67.2 mo; range, 60-76) after the surgery. We analyzed the preoperative and intraoperative parameters using univariate and multivariate regression for cure rates and patients' satisfaction. RESULTS: The overall 5-yr cure rate was 76.8%, with a satisfaction rate of 86.9%. The cure rates were lower in patients with high body mass index (BMI>or=25 kg/m2/BMI<25 kg/m2=68.3%:83.3%, p=0.044), low abdominal leak point pressure (ALPP<60 cm H2O/ALPP>or=60 cm H2O=51.6%:82.8%, p=0.003), and high grade of SUI (40.0% in grade III; 69.7% in grade II; 86.6% in grade I, p=0.012). On multivariate analysis, there were no independent risk factors related to cure rate, and urgency was the only factor independently associated with patients' satisfaction (p=0.017; odds ratio=4.114). CONCLUSIONS: This study demonstrates that the TVT procedure is effective for female SUI without any independent predictive factors affecting long-term cure rate. Urgency was the only predictive factor affecting patient satisfaction. However, high BMI, low ALPP, and high grade of incontinence may impair the cure rate of the TVT.     

Does Body Mass Index Impact Passing Voiding Trial After Midurethral Sling Procedures for Stress Urinary Incontinence?

OBJECTIVE:: To test the hypothesis that body mass index (BMI) is a factor associated with passing a voiding trial after midurethral sling procedures for stress urinary incontinence (SUI). STUDY DESIGN:: The medical records of 136 consecutive patients who underwent placement of either tension-free vaginal tape (TVT) or transobturator tape (TOT) for SUI during a 1-year period (September 1, 2007 to August 31, 2008) were retrospectively reviewed. Variables assessed were BMI, age, and passing or failing a postoperative urinary voiding trial. Patients with concomitant pelvic organ prolapse surgeries were not included in this analysis. RESULTS:: Sixty-seven patients underwent TVT, whereas 69 had TOT procedures. In the TVT group, 30 patients (42%) were unable to void immediately postoperatively compared with 11 patients (16%) in the TOT group (P = 0.0003). The mean (SD) age and BMI of patients who failed or passed voiding trials was 58.6 (12.0) years and 28.0 (4.9) kg/m or 53.5 (12.3) years and 29.8 (5.7) kg/m, respectively. Of 38 patients who did not pass a voiding trial on the day of the procedure, 31 (82%) passed on postoperative day 1, and all patients had passed a voiding trial by postoperative day 11. The mean (SD) BMI for 7 patients who did not pass voiding trial by postoperative day 1 was 28.3 (5.2) kg/m. CONCLUSIONS:: Women with higher BMIs were more likely to pass voiding trials after midurethral sling procedures. Patients who had TOT placement had greater success passing a postprocedure voiding trial than did patients who had TVT placement.     

Pelvicol pubovaginal sling versus tension-free vaginal tape for treatment of urodynamic stress incontinence: a prospective randomized three-year follow-up study

OBJECTIVES: The aim of this study was to compare the long-term success rates, complication rates and patient satisfaction rates for Pelvicol pubovaginal sling (Bard) versus TVT (Gynecare) in surgical treatment of urodynamic stress incontinence (USI) in women. DESIGN: Prospective randomized cohort trial. SETTING: District General Hospital, South West of England. METHODS: One hundred and forty-two women with urodynamic stress incontinence were randomized to either surgical procedure (Pelvicol = 74, TVT = 68) with median follow-up of 36 month. A postal questionnaire was sent to all women and the response rate was excellent at approximately 90% in both groups. RESULTS: Cure of incontinence, as identified by a quality of life improvement >90%, and/or patient-determined continent status as dry, were comparable in both groups. When the cure rates were adjusted assuming the non-respondents as failures the figures were almost identical (p > 0.05). Preoperative continence pad usage was similar for both groups. Overall, a postoperative significant decrease in pad score was noted in both groups (p = 0.01) but there was no significant difference between the groups (p > 0.05). Statistical analysis failed to detect significant differences between both groups as regards complication rates such as frequency, nocturia, de-novo urgency or dyspareunia. CONCLUSION: Pelvicol sling is a safe procedure in the surgical management of USI with similar success rate and patient satisfaction rate to TVT up to three years of follow-up.     

Body mass index and outcome of tension-free vaginal tape

OBJECTIVES: To assess the effectiveness of tension-free vaginal tape (TVT) in women with high body mass indices (BMIs). METHODS: Thirty-eight consecutive patients with BMIs exceeding 30 who underwent tension-free vaginal tape were compared with 149 consecutive patients with BMIs of 30 or less who underwent the same procedure. Body mass index was calculated pre-operatively and at follow-up. Women were classified as being of normal weight (BMI 20-25), overweight (BMI 26-30), or obese (BMI >30). Patient characteristics, operative and post-operative complications, reported continence rates were analyzed according to BMI. RESULTS: There were no significant differences between groups in terms of age, parity, menopausal status, previous surgery, type and degree of incontinence. Estimated blood loss, operative times, bladder injuries, post-operative urgency and voiding disorders did not differ significantly between women with high BMIs and those with low BMIs. Women with BMIs exceeding 30 had a significantly higher incidence of post-operative urge urinary incontinence (17.9 versus 3.4 and 6.4% p = 0.02) without any effects on the objective and subjective cure rates (82 versus 88.7 and 93% p = 0.1, 71.7 versus 72.1 and 74% p = 0.9). CONCLUSION: We did not find pre-operative obesity to be a risk factor for failure of tension-free vaginal tape.     

Comparative analysis of urinary incontinence severity after autologous fascia pubovaginal sling, pubovaginal sling and tension-free vaginal tape

PURPOSE: Autologous fascia, Pelvicol implant and polypropylene are common materials used in suburethral anti-incontinence procedures. We explored the relative effectiveness of the autologous fascia pubovaginal sling, Pelvicol pubovaginal sling and Gynecare TVT on self-reported postoperative urinary incontinence. MATERIALS AND METHODS: The study was a mailed cross-sectional survey of health related quality of life 1 to 3 years after suburethral anti-incontinence surgery performed at our institution. The Incontinence Symptom Index was used to assess the presence and severity of urinary incontinence symptoms and the Incontinence Impact Questionnaire-7 was used to assess impairment. Regression models were developed to identify factors with an independent effect on the presence, severity and impairment of urinary incontinence symptoms. RESULTS: The questionnaire was returned by 69% of eligible respondents (173 of 250). Those with previous incontinence surgery (OR 11.0, 95% CI 2.3-51.4) and medical comorbidities (OR 1.6, 95% CI 1.1-2.2) were more likely to report urinary incontinence symptoms, ie incontinence symptom index greater than 0. Symptom severity, which was analyzed only in respondents with urinary incontinence symptoms, was greater in the Pelvicol than in the autologous fascia pubovaginal sling and TVT groups (each p <0.01). No significant difference was observed between the TVT and autologous fascia pubovaginal sling groups (p = 0.15). Also associated with higher urinary incontinence symptom severity scores were body mass index (p = 0.03), a history of incontinence surgery (p = 0.01) and lower education (p <0.01). Impairment from urinary incontinence, as assessed by the Incontinence Impact Questionnaire-7, was associated with body mass index, severe depression and current smoking (each p = 0.01) but not with surgical treatment group. CONCLUSIONS: Women who received an autologous fascia pubovaginal sling or TVT reported lower symptom severity scores than those who had a Pelvicol pubovaginal sling. Impairment was not associated with procedure type. These findings suggest better outcomes with autologous fascia pubovaginal sling and TVT. Randomized, controlled trials are needed to confirm these findings.     

Five-year outcomes of the tension-free vaginal tape procedure for treatment of female stress urinary incontinence

OBJECTIVES: We evaluated the long-term efficacy and safety of a tension-free vaginal tape (TVT) procedure for the treatment of female stress urinary incontinence (SUI) in a Korean population. METHODS: We included 134 patients (mean age, 52.3+/-9.3 yr) who underwent the TVT procedure for SUI in three institutions and followed for 5 yr (mean, 67.0 mo; range, 60-76 mo) postoperatively. We analysed voiding diaries and complete multichannel urodynamic studies preoperatively as well as cough stress tests, uroflowmetry, and questionnaires postoperatively. RESULTS: The overall 5-yr success rates (cure/improved) were 94.9% (76.9% and 18.0%, respectively), with an 86.6% patient satisfaction rate. Although the success rates between 1 and 5 yr were similar (97.7% vs. 94.9%), the cure rate decreased from 90.1% to 76.9% (p<0.001) at 5 yr. The 5-yr cure rate for mixed urinary incontinence (MUI) was 72.0%, which was not significantly different from pure SUI (78.0%, p>0.05). Maximal flow rate dropped from 25.9+/-10.3ml/s to 20.4+/-8.6ml/s at 1 mo postoperatively and recovered to 24.8+/-8.5ml/s at 5 yr. Complications included bladder perforation in 5 patients (3.7%), tape cutting or release in 11 (8.2%), and persistent suprapubic pain in 3 (2.2%). Urgency and urge incontinence improved in 46.7% and 48.0% of patients, respectively. CONCLUSIONS: TVT was an effective and safe procedure for SUI and MUI with high success rates in the long-term follow-up. It also improved concomitant overactive bladder symptoms and initially reduced postoperative urine flow, which recovered over time.     

Tension-free vaginal tape: a prospective subjective and objective outcome analysis

The purpose of this prospective study was to describe the effects of the tension-free vaginal tape (TVT) procedure on subjective and objective outcomes. Eighty-seven women (aged 31–95 years) underwent a TVT procedure and were followed for up to 24 months using the Incontinence Impact Questionnaire (IIQ-7), Urogenital Distress Inventory (UDI-6), and a Patient Satisfaction Questionnaire. IIQ-7 scores improved from a mean 51.1 before surgery to 12.7 at 1 month (p<0.001) indicating reduced impact of incontinence on quality of life. UDI-6 scores declined from a mean 61.8 to 21.9 (p<0.001) indicating improvement in urinary symptoms. At 1 month, 91.2% of patients were satisfied. Improvements on all measures were maintained throughout follow-up. Urodynamic evaluation of 57 patients (mean: 15.0 months) showed that 91.2% had a negative stress test. Results indicate significant immediate and sustained improvement in incontinence impact and urinary symptoms, and a high rate of patient satisfaction and objective cure.Presented at American Urogynecologic Society Meeting, Hollywood, FL, September 2003
