Abstract
BACKGROUND Stress urinary incontinence imposes a significant health and economic burden on individuals and society. Single-incision slings are a minimally-invasive treatment option for stress urinary incontinence. They involve passing a short synthetic device through the anterior vaginal wall to support the mid-urethra. The use of polypropylene mesh in urogynaecology, including mid-urethral slings, is restricted in many countries. This is a review update (previous search date 2012). OBJECTIVES To assess the effects of single-incision sling operations for treating urinary incontinence in women, and to summarise the principal findings of relevant economic evaluations. SEARCH METHODS We searched the Cochrane Incontinence Specialised Register, which contains trials identified from: CENTRAL, MEDLINE, MEDLINE In-Process, MEDLINE Epub Ahead of Print, and two trials registers. We handsearched journals, conference proceedings, and reference lists of relevant articles to 20 September 2022. SELECTION CRITERIA We included randomised or quasi-randomised controlled trials in women with stress (or stress-predominant mixed) urinary incontinence in which at least one, but not all, trial arms included a single-incision sling. DATA COLLECTION AND ANALYSIS We used standard Cochrane methodological procedures. The primary outcome was subjective cure or improvement of urinary incontinence. MAIN RESULTS We included 62 studies with a total of 8051 women in this review. We did not identify any studies comparing single-incision slings to no treatment, conservative treatment, colposuspension, or laparoscopic procedures. We assessed most studies as being at low or unclear risk of bias, with five studies at high risk of bias for outcome assessment. Sixteen trials used TVT-Secur, a single-incision sling withdrawn from the market in 2013. The primary analysis in this review excludes trials using TVT-Secur. We report separate analyses for these trials, which did not substantially alter the effect estimates. We identified two cost-effectiveness analyses and one cost-minimisation analysis. Single-incision sling versus autologous fascial sling One study (70 women) compared single-incision slings to autologous fascial slings. It is uncertain if single-incision slings have any effect on risk of dyspareunia (painful sex) or mesh exposure, extrusion or erosion compared with autologous fascial slings. Subjective cure or improvement of urinary incontinence at 12 months, patient-reported pain at 24 months or longer, number of women with urinary retention, quality of life at 12 months and the number of women requiring repeat continence surgery or sling revision were not reported for this comparison. Single-incision sling versus retropubic sling Ten studies compared single-incision slings to retropubic slings. There may be little to no difference between single-incision slings and retropubic slings in subjective cure or improvement of incontinence at 12 months (risk ratio (RR) 0.99, 95% confidence interval (CI) 0.91 to 1.07; 2 trials, 297 women; low-certainty evidence). It is uncertain whether single-incision slings increase the risk of mesh exposure, extrusion or erosion compared with retropubic minimally-invasive slings; the wide confidence interval is consistent with both benefit and harm (RR 1.55, 95% CI 0.24 to 9.82; 3 trials, 267 women; low-certainty evidence). It is uncertain whether single-incision slings lead to fewer women having postoperative urinary retention compared with retropubic slings; the wide confidence interval is consistent with possible benefit and harm (RR 0.47, 95% CI 0.12 to 1.84; 2 trials, 209 women; low-certainty evidence). The effect of single-incision slings on the risk of repeat continence surgery or mesh revision compared with retropubic slings is uncertain (RR 4.19, 95% CI 0.31 to 57.28; 2 trials, 182 women; very low-certainty evidence). One study reported quality of life, but not in a suitable format for analysis. Patient-reported pain at more than 24 months and the number of women with dyspareunia were not reported for this comparison. We downgraded the evidence due to concerns about risks of bias, imprecision and inconsistency. Single-incision sling versus transobturator sling Fifty-one studies compared single-incision slings to transobturator slings. The evidence ranged from high to low certainty. There is no evidence of a difference in subjective cure or improvement of incontinence at 12 months when comparing single-incision slings with transobturator slings (RR 1.00, 95% CI 0.97 to 1.03; 17 trials, 2359 women; high-certainty evidence). Single-incision slings probably have a reduced risk of patient-reported pain at 24 months post-surgery compared with transobturator slings (RR 0.12, 95% CI 0.02 to 0.68; 2 trials, 250 women; moderate-certainty evidence). The effect of single-incision slings on the risk of dyspareunia is uncertain compared with transobturator slings, as the wide confidence interval is consistent with possible benefit and possible harm (RR 0.78, 95% CI 0.41 to 1.48; 8 trials, 810 women; moderate-certainty evidence). There are a similar number of mesh exposures, extrusions or erosions with single-incision slings compared with transobturator slings (RR 0.61, 95% CI 0.39 to 0.96; 16 trials, 2378 women; high-certainty evidence). Single-incision slings probably result in similar or reduced cases of postoperative urinary retention compared with transobturator slings (RR 0.68, 95% CI 0.47 to 0.97; 23 trials, 2891 women; moderate-certainty evidence). Women with single-incision slings may have lower quality of life at 12 months compared to transobturator slings (standardised mean difference (SMD) 0.24, 95% CI 0.09 to 0.39; 8 trials, 698 women; low-certainty evidence). It is unclear whether single-incision slings lead to slightly more women requiring repeat continence surgery or mesh revision compared with transobturator slings (95% CI consistent with possible benefit and harm; RR 1.42, 95% CI 0.94 to 2.16; 13 trials, 1460 women; low-certainty evidence). We downgraded the evidence due to indirectness, imprecision and risks of bias. AUTHORS' CONCLUSIONS Single-incision sling operations have been extensively researched in randomised controlled trials. They may be as effective as retropubic slings and are as effective as transobturator slings for subjective cure or improvement of stress urinary incontinence at 12 months. It is uncertain if single-incision slings lead to better or worse rates of subjective cure or improvement compared with autologous fascial slings. There are still uncertainties regarding adverse events and longer-term outcomes. Therefore, longer-term data are needed to clarify the safety and long-term effectiveness of single-incision slings compared to other mid-urethral slings.

Abstract
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. STUDY REGISTRATION This study is registered as PROSPERO CRD42016049339.

Is There Outcome Reporting Heterogeneity in Trials That Aim to Assess the Effectiveness of Surgical Treatments for Stress Urinary Incontinence in Women? Eur Urol Focus 2020; 7:857-868. [PMID: 32331796 DOI: 10.1016/j.euf.2020.03.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2020] [Revised: 03/12/2020] [Accepted: 03/24/2020] [Indexed: 10/24/2022]
Abstract
CONTEXT Inconsistent reporting of effectiveness outcomes in surgical trials of stress urinary incontinence (SUI) has hindered direct comparisons of various surgical treatments for SUI. OBJECTIVE To systematically review the verbatim outcome names, outcome definitions, and tools used to measure the outcomes in surgical trials of SUI in women. EVIDENCE ACQUISITION Trials of women with SUI who have undergone surgical interventions were included. We conducted a systematic review (SR) on outcomes reported in randomized controlled trials of surgical management published in 2014-2019, covering the following databases: MEDLINE, EMBASE, CENTRAL, and CDSR. Verbatim outcome names extracted from the included studies were categorized and then grouped into domains using the Williamson-Clarke (W/C) outcome taxonomy. A matrix was also created to visualize and quantify the dimensions of outcome reporting heterogeneity in SUI trials. EVIDENCE SYNTHESIS A total of 844 verbatim outcome names were extracted, of which, 514 varied terms were reduced to 71 standardized outcome names. They were further categorized into 11 domains from the W/C taxonomy. There were 7.24 different terms on average to describe each outcome, and the four outcomes with the most heterogeneity evident in terms used to describe them were "urinary retention", "reoperation", "subjective cure rate" and "quality of life". Each of them had ≥20 different terms. Only 28% of the outcome definitions were reported and a variety of measuring tools was noted, particularly in subjective outcomes. High heterogeneity was found in the outcome names, outcome definitions, choice and number of measuring instruments of the outcomes, and choice and number of outcomes reported across studies. CONCLUSIONS This SR provides objective evidence of heterogeneity in outcome reporting in SUI surgical trials. Our categorization of outcomes highlights the difficulties in summarizing the current evidence base. A core outcome set, developed using the methods advocated by the Core Outcome Measures in Effectiveness Trials (COMET) and COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) initiatives, is required. PATIENT SUMMARY In this research, we have highlighted the diversity in outcomes reporting in stress urinary incontinence (SUI) surgical trials and have categorized the outcomes. We support the development of a core outcome set for SUI, which will promote future clinical researchers to measure the same outcome in the same way in all trials. This will, in turn, help researchers summarize the evidence more effectively and aid decision making for patients and doctors.

Abstract
Aims: The aim of the study is to assess the feasibility of ambulatory stress urinary incontinence (SUI) surgery using the MiniArc Precise single-incision urethral sling without increasing the number of complications. Settings and Design: This was a retrospective observational study of prospectively collected data carried out in a Tertiary Referral Hospital in Barcelona, Spain. Materials and Methods: Forty patients diagnosed with SUI or stress predominant mixed urinary incontinence (MUI) treated surgically between November 2011 and November 2013. The MiniArc Precise® sling was inserted under local anesthesia in the ambulatory setting. Statistical Analysis Used: Descriptive statistics included frequencies and percentages for categorical variables and mean and range for quantitative variables. The statistical package used was SPSS version 17.0. Results: Urodynamic studies showed SUI in 78% of cases and stress predominant MUI in 17%. Clinical findings included SUI in 56% of cases and MUI in 44%, with positive stress tests in all participants. The mean intraoperative pain (1–10 Visual Analog Scale) was 2. All patients were satisfied with the use of local anesthesia in the outpatient setting. Perioperative complications did not occur. One case of urinary retention and two cases of urinary tract infection (UTI) developed within this 1st month after operation and were successfully managed conservatively. Midterm complications included eight cases of UTI and four de novo urge incontinence. Conclusions: Placement of the MiniArc Precise sling under local anesthesia is a feasible and safe technique, which when carried out by an experienced surgeon allows to be done as an outpatient basis without increasing the rate of postprocedural complications.

Abstract
BACKGROUND To assess the current evidence of effectiveness and safety of single-incision mini-slings (MiniArc) versus transobturator midurethral slings in the management of female stress urinary incontinence (SUI). METHODS A systematic search was performed from the electronic databases including PubMed, EMBASE, and Cochrane Library by November 2017. Using RevMan5.3 statistical software, the primary outcomes including subject and objective cure rates at 6 to 24 months follow-up were evaluated. Meanwhile, analysis was also performed for comparing the secondary outcomes such as peri- and postoperative complications, operative data, and quality of life. RESULTS Six randomized controlled trials (RCTs) and 6 retrospective cohort studies involving 1794 patients with SUI were analyzed based on the inclusion criteria. On the basis of our analysis, MiniArc was proven to have a noninferior clinical efficacy compared with transobturator midurethral slings with respect to the objective cure rate (risk ratio [RR] = 0.98, 95% confidence interval [CI] 0.94-1.03, P = .43) and subjective cure rate (RR = 0.97, 95% CI 0.91-1. 04, P = .38). In addition, pooled analysis showed that MiniArc had significantly lower postoperative pain scores (mean difference [MD] = -1.70, 95% CI -3.17 to -0.23, P = .02) and less postoperative groin pain (RR = 0.42, 95% CI 0.18-0.98, P = .04). Moreover, the MiniArc group also had a significantly shorter operation time (MD = -6.12, 95% CI -8.61 to -3.64, P < .001), less blood loss (MD = -16.67, 95% CI -26.29 to -7.05, P < .001), shorter in-patient stay (MD = 1.30, 95% CI -1.74 to -0.86, P < .001), and less urinary retention risk (RR = 1.15, 95% CI 0.46-2.87, P = .77). However, overall evidence was insufficient to suggest a statistically significant difference in the adverse event profile for MiniArc compared with transobturator slings. CONCLUSIONS This meta-analysis indicates that MiniArc is an effective method treating SUI. When compared with transobturator slings, it not only has a similar high cure rates, but also is associated with shorter operation time, less blood loss, more favorable recovery time, lower postoperative pain scores, less postoperative groin pain, less urinary retention, and absence of a visible wound. However, the findings of this study should be further confirmed by well-designed prospective RCTs with a larger patient series.
