A prospective randomized trial comparing a modified needle suspension procedure with the vagina/obturator shelf procedure for genuine stress incontinence

Surgical treatments for women with stress urinary incontinence: the ESTER systematic review and economic evaluation

BACKGROUND

Urinary incontinence in women is a distressing condition that restricts quality of life and results in a large economic burden to both the NHS and women themselves.

OBJECTIVE

To evaluate the clinical effectiveness, safety and cost-effectiveness of surgical treatment for stress urinary incontinence (SUI) in women and explore women's preferences.

DESIGN

An evidence synthesis, a discrete choice experiment (DCE) and an economic decision model, with a value-of-information (VOI) analysis. Nine surgical interventions were compared. Previous Cochrane reviews for each were identified and updated to include additional studies. Systematic review methods were applied. The outcomes of interest were 'cure' and 'improvement'. Both a pairwise and a network meta-analysis (NMA) were conducted for all available surgical comparisons. A DCE was undertaken to assess the preferences of women for treatment outcomes. An economic model assessed the cost-effectiveness of alternative surgeries and a VOI analysis was undertaken.

RESULTS

Data from 175 studies were included in the effectiveness review. The majority of included studies were rated as being at high or unclear risk of bias across all risk-of-bias domains. The NMA, which included 120 studies that reported data on 'cure' or 'improvement', showed that retropubic mid-urethral sling (MUS), transobturator MUS, traditional sling and open colposuspension were more effective than other surgical procedures for both primary outcomes. The results for other interventions were variable. In general, rate of tape and mesh exposure was higher after transobturator MUS than after retropubic MUS or single-incision sling, whereas the rate of tape or mesh erosion/extrusion was similar between transobturator MUS and retropubic MUS. The results of the DCE, in which 789 women completed an anonymous online questionnaire, indicate that women tend to prefer surgical treatments associated with no pain or mild chronic pain and shorter length of hospital stay as well as those treatments that have a smaller risk for urinary symptoms to reoccur after surgery. The cost-effectiveness results suggest that, over a lifetime, retropubic MUS is, on average, the least costly and most effective surgery. However, the high level of uncertainty makes robust estimates difficult to ascertain. The VOI analysis highlighted that further research around the incidence rates of complications would be of most value.

LIMITATIONS

Overall, the quality of the clinical evidence was low, with limited data available for the assessment of complications. Furthermore, there is a lack of robust evidence and significant uncertainty around some parameters in the economic modelling.

CONCLUSIONS

To our knowledge, this is the most comprehensive assessment of published evidence for the treatment of SUI. There is some evidence that retropubic MUS, transobturator MUS and traditional sling are effective in the short to medium term and that retropubic MUS is cost-effective in the medium to long term. The VOI analysis highlights the value of further research to reduce the uncertainty around the incidence rates of complications. There is a need to obtain robust clinical data in future work, particularly around long-term complication rates.

Bladder neck needle suspension for urinary incontinence in women

BACKGROUND

Bladder neck needle suspension is an operation traditionally used for moderate or severe stress urinary incontinence in women. About a third of adult women experience some urinary incontinence, and about a third of these have moderate or severe symptoms. Stress urinary incontinence (SUI) imposes significant health and economic burdens on society and the women affected.

OBJECTIVES

To determine the effects of needle suspension on stress or mixed urinary incontinence in comparison with other management options.

SEARCH METHODS

We searched the Cochrane Incontinence Group Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE in process, ClinicalTrials.gov, WHO ICTRP and handsearching of journals and conference proceedings (searched 12 November 2014), and the reference lists of relevant articles.

SELECTION CRITERIA

Randomised or quasi-randomised trials that included needle suspension for the treatment of urinary incontinence.

DATA COLLECTION AND ANALYSIS

At least two authors assessed trials and extracted data independently. Two trial investigators provided additional information.

MAIN RESULTS

We identified 10 trials, which included 375 women having six different types of needle suspension procedures and 489 who received comparison interventions. Needle suspensions were more likely to fail than open abdominal retropubic suspension. There was a higher subjective failure rate after the first year (91/313 (29%) failed versus 47/297 (16%) failed after open abdominal retropubic suspension). The risk ratio (RR) was 2.00 (95% confidence interval (CI) 1.47 to 2.72), although the difference in peri-operative complications was not significant (17/75 (23%) versus 12/77 (16%); RR 1.44, 95% CI 0.73 to 2.83). There were no significant differences for the other outcome measures. This effect was seen in both women with primary incontinence and women with recurrent incontinence after failed primary operations. Needle suspensions may be as effective as anterior vaginal repair (50/156 (32%) failed after needle suspension versus 64/181 (35%) after anterior repair; RR 0.86, 95% CI 0.64 to 1.16), but there was little information about morbidity. Data for comparison with suburethral slings were inconclusive because they came from a small and atypical population.No trials compared needle suspensions with conservative management, peri-urethral injections, or sham or laparoscopic surgery.

AUTHORS' CONCLUSIONS

Bladder neck needle suspension surgery is probably not as good as open abdominal retropubic suspension for the treatment of primary and secondary urodynamic stress incontinence because the cure rates were lower in the trials reviewed. However, the reliability of the evidence was limited by poor quality and small trials. There was not enough information to comment on comparisons with suburethral sling operations. Although cure rates were similar after needle suspension compared with after anterior vaginal repair, the data were insufficient to be reliable and inadequate to compare morbidity. A Brief Economic Commentary (BEC) identified no cost-effectiveness studies comparing bladder neck needle suspension with other surgeries.

Open retropubic colposuspension for urinary incontinence in women

BACKGROUND

Urinary incontinence is a common and potentially debilitating problem. Stress urinary, incontinence as the most common type of incontinence, imposes significant health and economic burdens on society and the women affected. Open retropubic colposuspension is a surgical treatment which involves lifting the tissues near the bladder neck and proximal urethra in the area behind the anterior pubic bones to correct deficient urethral closure to correct stress urinary incontinence.

OBJECTIVES

The review aimed to determine the effects of open retropubic colposuspension for the treatment of urinary incontinence in women. A secondary aim was to assess the safety of open retropubic colposuspension in terms of adverse events caused by the procedure.

SEARCH METHODS

We searched the Cochrane Incontinence Group Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE in process, ClinicalTrials.gov, WHO ICTRP and handsearching of journals and conference proceedings (searched 5 May 2015), and the reference lists of relevant articles. We contacted investigators to locate extra studies.

SELECTION CRITERIA

Randomised or quasi-randomised controlled trials in women with symptoms or urodynamic diagnoses of stress or mixed urinary incontinence that included open retropubic colposuspension surgery in at least one trial group.

DATA COLLECTION AND ANALYSIS

Studies were evaluated for methodological quality or susceptibility to bias and appropriateness for inclusion and data extracted by two of the review authors. Trial data were analysed by intervention. Where appropriate, a summary statistic was calculated.

MAIN RESULTS

This review included 55 trials involving a total of 5417 women.Overall cure rates were 68.9% to 88.0% for open retropubic colposuspension. Two small studies suggested lower incontinence rates after open retropubic colposuspension compared with conservative treatment. Similarly, one trial suggested lower incontinence rates after open retropubic colposuspension compared to anticholinergic treatment. Evidence from six trials showed a lower incontinence rate after open retropubic colposuspension than after anterior colporrhaphy. Such benefit was maintained over time (risk ratio (RR) for incontinence 0.46; 95% CI 0.30 to 0.72 before the first year, RR 0.37; 95% CI 0.27 to 0.51 at one to five years, RR 0.49; 95% CI 0.32 to 0.75 in periods beyond five years).Evidence from 22 trials in comparison with suburethral slings (traditional slings or trans-vaginal tape or transobturator tape) found no overall significant difference in incontinence rates in all time periods evaluated (as assessed subjectively RR 0.90; 95% CI 0.69 to 1.18, within one year of treatment, RR 1.18; 95%CI 1.01 to 1.39 between one and five years, RR 1.11; 95% CI 0.97 to 1.27 at five years and more, and as assessed objectively RR 1.24; 95% CI 0.93 to 1.67 within one year of treatment, RR 1.12; 95% CI 0.82 to 1.54 for one to five years follow up, RR 0.70; 95% CI 0.30 to 1.64 at more than five years). However, subgroup analysis of studies comparing traditional slings and open colposuspension showed better effectiveness with traditional slings in the medium and long term (RR 1.35; 95% CI 1.11 to 1.64 from one to five years follow up, RR 1.19; 95% CI 1.03 to 1.37).In comparison with needle suspension, there was a lower incontinence rate after colposuspension in the first year after surgery (RR 0.66; 95% CI 0.42 to 1.03), after the first year (RR 0.56; 95% CI 0.39 to 0.81), and beyond five years (RR 0.32; 95% CI 15 to 0.71).Patient-reported incontinence rates at short, medium and long-term follow-up showed no significant differences between open and laparoscopic retropubic colposuspension, but with wide confidence intervals. In two trials incontinence was less common after the Burch (RR 0.38; 95% CI 0.18 to 0.76) than after the Marshall Marchetti Krantz procedure at one to five year follow-up. There were few data at any other follow-up times.In general, the evidence available does not show a higher morbidity or complication rate with open retropubic colposuspension compared to the other open surgical techniques, although pelvic organ prolapse is more common than after anterior colporrhaphy and sling procedures. Voiding problems are also more common after sling procedures compared to open colposuspension.

AUTHORS' CONCLUSIONS

Open retropubic colposuspension is an effective treatment modality for stress urinary incontinence especially in the long term. Within the first year of treatment, the overall continence rate is approximately 85% to 90%. After five years, approximately 70% of women can expect to be dry. Newer minimal access sling procedures look promising in comparison with open colposuspension but their long-term performance is limited and closer monitoring of their adverse event profile must be carried out. Open colposuspension is associated with a higher risk of pelvic organ prolapse compared to sling operations and anterior colporrhaphy, but with a lower risk of voiding dysfunction compared to traditional sling surgery. Laparoscopic colposuspension should allow speedier recovery but its relative safety and long-term effectiveness is not yet known. A Brief Economic Commentary (BEC) identified five studies suggesting that tension-free vaginal tape (TVT) and laparoscopic colposuspension may be more cost-effective compared with open retropubic colposuspension.

Advances in the SUI Surgeries

Stress urinary incontinence is a condition associated with advancing age and high parity. Millions of women all over the world have suffered, in silence, embarrassment and social isolation due to this condition. Over the years, several operative procedures have evolved for correction of urinary incontinence with many of them having poor success or high recurrence rates over long-term period. This mini review covers various surgical procedures evolved over the last couple of years and recent advances in the management of urinary incontinence.

The Long-Term Outcome of the Turner-Warwick Vaginal Obturator Shelf Urethral Repositioning Colposuspension Procedure for Urodynamically Proven Stress Urinary Incontinence

OBJECTIVE

To analyze long-term continence, voiding dysfunction and secondary prolapse rates following Turner-Warwick Vaginal Obturator Shelf Urethral Repositioning colposuspension (VOSURP) for urodynamically proven stress urinary incontinence (USUI).

PATIENTS AND METHODS

Telephone and/or outpatient review of the outcomes of 50 consecutive patients undergoing VOSURP between 1997 and 2008 was conducted. Outcomes assessed included urinary continence (pad free/leak free), need to self-catheterise (ISC), secondary posterior pelvic organ prolapse (POP) development and need for further continence and POP-related surgical interventions. All patients with continued/recurrent urinary incontinence had repeat videourodynamics.

RESULTS

At a median follow-up of 108.5 months (17-153), complete urinary continence was reported in 41 (82%) of patients, post procedure new onset ISC in 2 (4%) and new onset posterior POP in 2 (4%). The cause of continued urinary incontinence was persistent USUI in 3 (6%), new onset idiopathic detrusor overactivity (IDO) in 4 (8%) and failure of resolution of pre-existing IDO in 2 (4%).

CONCLUSIONS

Long-term complete urinary continence and cure of USUI following VOSURP are excellent at 82 and 94%, respectively. Voiding dysfunction and secondary POP procedure rates are low. The VOSURP is an excellent alternative to classical Burch colposuspension for the treatment of primary and recurrent USUI.

Surgical treatment of recurrent stress urinary incontinence in women: a systematic review and meta-analysis of randomised controlled trials

CONTEXT

Recurrent stress urinary incontinence (R-SUI) represents a management dilemma; however, only a limited number of randomised controlled trials (RCTs) have assessed the various surgical procedures used for its treatment.

OBJECTIVE

To assess the effectiveness and complications of various surgical procedures for the treatment of female R-SUI.

EVIDENCE ACQUISITION

A prospective peer-reviewed protocol was prepared a priori. A systematic literature review of all published RCTs comparing surgical procedures for treatment of R-SUI was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analysis statement. Data were analysed using RevMan 5.

EVIDENCE SYNTHESIS

We conducted a literature search from 1945 to February 2013. Data were available for a total of 350 women in 10 RCTs with a mean follow-up of 18.1 mo. Meta-analysis was possible for the comparison of retropubic tension-free vaginal tape (RP-TVT) versus transobturator tension-free vaginal tape (TO-TVT) in five RCTs (n = 135). There was no statistically significant difference between RP-TVT and TO-TVT in the patient-reported improvement (odds ratio [OR]: 0.84, 95% confidence interval [CI], 0.41-1.69) or objective cure/improvement (OR: 1.75; 95% CI, 0.86-3.54). One RCT showed a trend towards a higher rate of patient-reported and objective cure/improvement with the inside-out TO-TVT compared with the outside-in; however, it was not statistically significant (OR: 3.00; 95% CI, 0.85-10.57, and OR: 3.32; 95% CI, 0.96-11.41, respectively). There was no significant difference between Burch colposuspension and RP-TVT (one RCT) in patient-reported improvement (OR: 0.33; 95% CI, 0.01-8.57) or objective cure/improvement (OR: 0.52; 95% CI, 0.13-2.05).

CONCLUSIONS

This meta-analysis shows no evidence of a significant difference in patient-reported and objective cure/improvement rates between RP-TVT and TO-TVT in the surgical treatment of women with R-SUI. However, due to the relatively low number of patients, the analysis might be underpowered. This review highlights the poor level of evidence in this field and the need for well-designed clinical trials to address this important clinical dilemma.

SEARCH STRATEGY

We searched the Cochrane Incontinence Group Specialised Register (searched 30 June 2008) and reference lists of relevant articles. We contacted investigators to locate extra studies.

SELECTION CRITERIA

Randomised or quasi-randomised controlled trials in women with symptoms or urodynamic diagnoses of stress or mixed urinary incontinence that included open retropubic colposuspension surgery in at least one trial group.

DATA COLLECTION AND ANALYSIS

Studies were evaluated for methodological quality/susceptibility to bias and appropriateness for inclusion and data extracted by two of the reviewers. Trial data were analysed by intervention. Where appropriate, a summary statistic was calculated.

MAIN RESULTS

This review included 46 trials involving a total of 4738 women.Overall cure rates were 68.9% to 88.0% for open retropubic colposuspension. Two small studies suggest lower failure rates after open retropubic colposuspension compared with conservative treatment. Similarly, one trial suggests lower failure rates after open retropubic colposuspension compared to anticholinergic treatment. Evidence from six trials showed a lower failure rate for subjective cure after open retropubic colposuspension than after anterior colporrhaphy. Such benefit was maintained over time (RR of failure 0.51; 95% CI 0.34 to 0.76 before the first year, RR 0.43; 95% CI 0.32 to 0.57 at one to five years, RR 0.49; 95% CI 0.32 to 0.75 in periods beyond 5 years). In comparison with needle suspensions there was a lower failure rate after colposuspension in the first year after surgery (RR 0.66; 95% CI 0.42 to 1.03), after the first year (RR 0.48; 95% CI 0.33 to 0.71), and beyond five years (RR 0.32; 95% CI 15 to 0.71). Evidence from twelve trials in comparison with suburethral slings found no significant difference in failure rates in all time periods assessed. Patient-reported failure rates in short, medium and long-term follow-up showed no significant difference between open and laparoscopic retropubic colposuspension, but with wide confidence intervals. In two trials failure was less common after Burch (RR 0.38 95% CI 0.18 to 0.76) than after the Marshall Marchetti Krantz procedure at one to five year follow-up. There were few data at any other follow-up time.In general, the evidence available does not show a higher morbidity or complication rate with open retropubic colposuspension, compared to the other open surgical techniques, although pelvic organ prolapse is more common than after anterior colporrhaphy and sling procedures.

AUTHORS' CONCLUSIONS

The evidence available indicates that open retropubic colposuspension is an effective treatment modality for stress urinary incontinence especially in the long term. Within the first year of treatment, the overall continence rate is approximately 85 to 90%. After five years, approximately 70% of patients can expect to be dry. Newer minimal access procedures like tension free vaginal tape look promising in comparison with open colposuspension but their long-term performance is not known and closer monitoring of its adverse event profile must be done. Laparoscopic colposuspension should allow speedier recovery but its relative safety and effectiveness is not known yet.

The modified rectus fascial sling for the treatment of genuine stress incontinence

We aimed to assess the results of the modified rectus fascial sling for the treatment of genuine stress incontinence (GSI), using an observational study of patients at a South Wales Teaching Hospital. Seventy-three patients with proven GSI underwent a modified rectus fascial sling. Thirty-seven also had a significant urge component to their symptoms though only two had demonstrable detrusor instability. Fifty-one had undergone previous incontinence surgery. All had pre-operative videourodynamics and 50 agreed to follow up urodynamics. Of these who had undergone previous surgery 48 (94%) were subjectively dry, though four (8%) still demonstrated GSI on videourodynamics. There were no failures in the previously unoperated group. Three require long-term intermittent self-catheterisation and three others catheterise occasionally. Overall, 29 patients (78%) were improved or cured of their urge component but three were worse, with urge incontinence. From our data, it seems that the modified rectus fascial sling is superior to standard techniques for GSI especially in patients who have undergone previous surgery. However loosely the sling is placed, a small but significant group are obstructed by the procedure, and may require self-catheterisation.

OBJECTIVES

To assess the effects of open retropubic colposuspension for the treatment of urinary incontinence.

SEARCH STRATEGY

We searched the Cochrane Incontinence Group Specialised Register (searched 30 June 2008) and reference lists of relevant articles. We contacted investigators to locate extra studies.

SELECTION CRITERIA

Randomised or quasi-randomised controlled trials in women with symptoms or urodynamic diagnoses of stress or mixed urinary incontinence that included open retropubic colposuspension surgery in at least one trial group.

DATA COLLECTION AND ANALYSIS

Studies were evaluated for methodological quality/susceptibility to bias and appropriateness for inclusion and data extracted by two of the reviewers. Trial data were analysed by intervention. Where appropriate, a summary statistic was calculated.

MAIN RESULTS

This review included 46 trials involving a total of 4738 women.Overall cure rates were 68.9% to 88.0% for open retropubic colposuspension. Two small studies suggest lower failure rates after open retropubic colposuspension compared with conservative treatment. Similarly, one trial suggests lower failure rates after open retropubic colposuspension compared to anticholinergic treatment. Evidence from six trials showed a lower failure rate for subjective cure after open retropubic colposuspension than after anterior colporrhaphy. Such benefit was maintained over time (RR of failure 0.51; 95% CI 0.34 to 0.76 before the first year, RR 0.43; 95% CI 0.32 to 0.57 at one to five years, RR 0.49; 95% CI 0.32 to 0.75 in periods beyond 5 years). In comparison with needle suspensions there was a lower failure rate after colposuspension in the first year after surgery (RR 0.66; 95% CI 0.42 to 1.03), after the first year (RR 0.48; 95% CI 0.33 to 0.71), and beyond five years (RR 0.32; 95% CI 15 to 0.71). Evidence from twelve trials in comparison with suburethral slings found no significant difference in failure rates in all time periods assessed. Patient-reported failure rates in short, medium and long-term follow-up showed no significant difference between open and laparoscopic retropubic colposuspension, but with wide confidence intervals. In two trials failure was less common after Burch (RR 0.38 95% CI 0.18 to 0.76) than after the Marshall Marchetti Krantz procedure at one to five year follow-up. There were few data at any other follow-up time.In general, the evidence available does not show a higher morbidity or complication rate with open retropubic colposuspension, compared to the other open surgical techniques, although pelvic organ prolapse is more common than after anterior colporrhaphy and sling procedures.

AUTHORS' CONCLUSIONS

The evidence available indicates that open retropubic colposuspension is an effective treatment modality for stress urinary incontinence especially in the long term. Within the first year of treatment, the overall continence rate is approximately 85 to 90%. After five years, approximately 70% of patients can expect to be dry. Newer minimal access procedures like tension free vaginal tape look promising in comparison with open colposuspension but their long-term performance is not known and closer monitoring of its adverse event profile must be done. Laparoscopic colposuspension should allow speedier recovery but its relative safety and effectiveness is not known yet.

Choice of surgery for stress incontinence

OBJECTIVE

To outline the evidence for the efficacy of surgical procedures used for the primary treatment of urinary incontinence.

OPTIONS

The range of surgical options available for the primary treatment of urinary incontinence in women.

OUTCOMES

The best possible outcomes for women undergoing primary surgery for urinary incontinence. To provide a current understanding of the evidence available as the basis of an informed discussion of the anticipated outcome of surgery.

EVIDENCE

A systematic review of clinical trials of the outcomes of primary surgical treatment of urinary incontinence.

VALUES

The quality of the evidence is rated using the criteria described by the Canadian Task Force on periodic health examination (Table).

BENEFITS, HARMS, AND COSTS

Careful consideration of the surgical options available will result in informed choice, which is essential to the process of determining the most appropriate surgery for a woman. Use of a range of surgeries that have the highest proven efficacy is most likely to result in long-term patient satisfaction.

Évolution des différentes voies d’abord chirurgicales dans l’incontinence urinaire d’effort féminine

OBJECTIVE

To review the surgical routes currently used in the treatment of female stress urinary incontinence (SUI).

PATIENTS AND METHODS

We have carried out a review of the international literature on Medline between 1968 and 2004, on surgical techniques for the treatment of female stress urinary incontinence (SUI). We have analysed articles that permitted to understand the evolution of surgical routes for 35 years. We have also sent a postal questionnaire to all Gynecology and Urology departments from the 25 University Hospitals of the Assistance Publique - Hopitaux de Paris (AP-HP) in France. All these departments were interviewed on the number of procedures performed between 1(st) September 2002 and 31(st) August 2003, the techniques used, the types and surgical routes of sub-urethral slings.

RESULTS

We report principles, results and morbidity of the surgical routes currently used in the treatment of female SUI: Burch colposuspension, Goebell-Stoeckell operation, sub-urethral prosthetic slings (retro-pubic and trans-obturator), urethral injections and artificial urinary sphincter. As regards the postal questionnaires, we have obtained answers from 22 departments out of 25 (88%). The total number of procedures for surgical treatment of SUI was 1224, 586 by the gynecologist (47.9%) and 638 by the urologist (52.1%). The techniques used were: 1028 sub-urethral prosthetic slings (83.9%), 106 Burch colposuspensions (8.7%), 70 artificial urinary sphincters (5.7%), 13 Goebell-Stoeckell operations (1.1%) and 7 urethral injections (0.6%). The tapes used were: 614 TVT (59.7%), 217 TOT (21.1%) - Uratape or Obtape -, 111 SPARC (10.8%), 40 PROLENE (3.9%), 27 URETEX (2.6%), 7 PELVICOL (0.7%), 6 SIS (0.6%) and 6 IVS (0.6%). The surgical routes were: retro-pubic down-up in 60.2%, trans-obturator in 26.9%, retro-pubic up-down in 10,8% and pre-pubic in 2.1%.

DISCUSSION AND CONCLUSION

The TVT procedure is widely used for surgical treatment of female SUI. The trans-obturator approach, which allows a morbidity reduction, was the route of choice in more than 25% at the AP-HP in 2002-2003.

Bladder neck needle suspension for urinary incontinence in women

BACKGROUND

Bladder neck needle suspension is an operation traditionally used for moderate or severe stress urinary incontinence in women. About a third of adult women experience some urinary incontinence, and about a third of them have moderate or severe symptoms.

OBJECTIVES

To determine the effects of needle suspension on stress or mixed urinary incontinence in comparison with other management options.

SEARCH STRATEGY

We searched the Cochrane Incontinence Group trials register (searched 18 September 2003). The reference lists of relevant articles were also searched.

SELECTION CRITERIA

Randomised or quasi-randomised trials that included needle suspension for the treatment of urinary incontinence.

DATA COLLECTION AND ANALYSIS

Trials were assessed and data extracted independently by at least two reviewers. Two trial investigators provided additional information.

MAIN RESULTS

Nine trials were identified which included 347 women having six different types of needle suspension procedures and 437 who received comparison interventions. Needle suspensions were more likely to fail than open abdominal retropubic suspension (higher subjective failure rate after the first year (91/313, 29% failed versus 47/297, 16% failed after open abdominal retropubic suspension: the relative risk (RR) was 2.00 (95% confidence interval (CI) 1.47 to 2.72) although the difference in peri-operative complications was not significant (17/75, 23% versus 12/77, 16%; RR 1.44, 95% CI 0.73 to 2.83): there were no significant differences for other outcome measures. This effect was seen in both women with primary incontinence and women with recurrent incontinence after failed primary operations. Needle suspensions may be as effective as anterior vaginal repair (46/128, 36% failed after needles versus 50/129, 39% after anterior repair; RR 0.93, 95% CI 0.68 to 1.26) but there was little information about morbidity. Data for comparison with suburethral slings were inconclusive because they came from a small and atypical population. No trials compared needle suspensions with conservative management, peri-urethral injections, sham or laparoscopic surgery.

REVIEWERS' CONCLUSIONS

Bladder neck needle suspension surgery is probably not as good as open abdominal retropubic suspension for the treatment of primary and secondary urodynamic stress incontinence because the cure rates were lower in the trials reviewed. However, the reliability of the evidence was limited by poor quality and small trials. There was not enough information to comment on comparisons with suburethral sling operations. Although cure rates were similar after needle suspension compared with after anterior vaginal repair, the data were insufficient to be reliable and inadequate to compare morbidity.

DATA COLLECTION AND ANALYSIS

Trials were assessed and data extracted independently by at least two reviewers. One trial investigator was contacted for additional information.

MAIN RESULTS

Eight trials were identified which included 327 women having six different types of needle suspension procedures and 407 who received comparison interventions. Needle suspensions were more likely to fail than open abdominal retropubic suspension (higher subjective failure rate after the first year (70/267, 26% failed vs 33/243, 14% failed after open abdominal retropubic suspension: RR 2.10, 95% CI 1.45 to 3.04) and there were more peri-operative complications (36/75, 48% vs 23/77, 30%; RR 1.51, 95% CI 1.06 to 2.15), but there were no significant differences for other outcome measures. This effect was confined to women with primary incontinence: too few women with recurrent incontinence were studied to draw conclusions about the effects of secondary operations. Needle suspensions may be as effective as anterior vaginal repair (46/128, 36% failed after needles vs 50/129, 39% after anterior repair; RR 0.93, 95% CI 0.68 to 1.26) but there was little information about morbidity.

REVIEWER'S CONCLUSIONS

Bladder neck needle suspension surgery is probably not as good as open abdominal retropubic suspension for the treatment of primary genuine stress urinary incontinence in terms of lower cure rates and higher morbidity. However, the reliability of the evidence was limited by poor quality and small trials. There was not enough information to comment on secondary procedures or on comparisons with suburethral sling operations. Although cure rates were similar after needle suspension compared with after anterior vaginal repair, the data were insufficient to be reliable and inadequate to compare morbidity.

A prospective randomized study comparing modified Burch retropubic urethropexy and suburethral sling for treatment of genuine stress incontinence with low-pressure urethra

OBJECTIVE

The aim of this study was to compare a modified Burch procedure with a suburethral sling for the treatment of stress incontinence complicated by a low-pressure urethra.

STUDY DESIGN

Thirty-six women with stress incontinence, low-pressure urethra, and urethral hypermobility (straining cotton swab angle >/=30 degrees ) were randomly assigned to undergo either a modified Burch procedure (n = 19) or a suburethral sling (n = 17). Objective and subjective cure rates at 3 months after the operation were the primary outcome measures. Comparisons of group means were performed with the Student t test for independent groups, and proportions were compared with the Fisher exact test.

RESULTS

After the operation the 2 groups had statistically similar cure rates and voiding function. Urethral closure pressure, pressure transmission ratios, and maximum detrusor pressure during voiding were significantly higher in the sling group.

CONCLUSION

At 3 months there were no clinically significant differences between the groups treated with suburethral sling and modified Burch procedures.

An assessment of the surgical outcome and urodynamic effects of the pubovaginal sling for stress incontinence and the associated urge syndrome

PURPOSE

We assessed the urodynamic changes after pubovaginal sling procedure for stress incontinence, particularly in regard to the associated symptoms of urgency, frequency, nocturia and urge incontinence, known as the urge syndrome.

MATERIALS AND METHODS

A total of 85 women with proved stress incontinence underwent a pubovaginal sling procedure using rectus fascia between 1992 and August 1996. Of the women 41 (48%) had undergone previous anti-incontinence surgery and 59 (69%) had the associated urge syndrome. There was at least some degree of hypermobility in 51 cases and type III stress incontinence was diagnosed in 34. Patients were assessed with a questionnaire and video urodynamics preoperatively and 3 months postoperatively. Preoperative and postoperative ambulatory studies were performed in 25 cases.

RESULTS

Of the 85 patients 83 (97%) were symptomatically cured of stress incontinence. The urge syndrome resolved in 32 patients (69%), almost all of whom had a closed bladder neck at rest. Overall bladder neck incompetence at rest decreased from 57 to 18% (p<0.001). Of 27 patients with the persistent urge syndrome postoperatively 9 (41%) had an open bladder neck at rest compared to 4 of 50 (8%) without urge incontinence (p<0.01). Despite symptomatic control of stress incontinence in 83 patients (97%), only 66 were satisfied with the surgical result, mainly because of the persistent urge syndrome in 27. Despite care to avoid obstruction overall, there were statistically significant obstructive changes in detrusor pressure at maximum flow rate, maximum flow rate and residual urine volumes.

CONCLUSIONS

The pubovaginal sling is effective in curing genuine stress incontinence and, when correctly placed at the right tension, the associated urge syndrome also can be managed, usually by achieving bladder neck closure at rest. However, despite careful maneuvers, obstruction occasionally persists.
