The MiniArc sling for female stress urinary incontinence: clinical results after 1-year follow-up

Comparison of Clinical Outcomes on Short Tape Single-Incision Sling Devices (Solyx) and Adjustable Length Device (I-Stop-Mini) for Urodynamic Stress Incontinence at 1 Year

INTRODUCTION AND HYPOTHESIS

The study is primarily aimed at comparing the outcome of voiding dysfunction related to over-tension and the resumption of normal voiding after tension-releasing suture (TRS) manipulation following Solyx and I-stop-mini procedures. Second, it is aimed at determining the cure rate, complications, and quality of life at 1 year postoperatively.

METHODS

This is a retrospective study conducted from March 2015 to June 2023. Patients with clinically confirmed pure stress urinary incontinence (SUI) and urodynamic stress incontinence were included; those with pelvic organ prolapse (POP) greater than stage II, neurogenic lower urinary tract dysfunction, or post-void residual of more than 100 ml were excluded. Standardized preoperative evaluations and TRS were used. Follow-ups were conducted at 1 week, 1 month, 3 months, 6 months, and annually. Statistical analyses were performed using SPSS version 17.

RESULTS

Out of 453 patients, 333 underwent Solyx and 120 underwent I-stop-mini procedures. The mean age was 56.6 years with an average BMI of 25.4. After Solyx, 18.9% had urinary retention whereas 10.8% had urinary retention after I-stop-mini. TRS manipulation was done in 12% post-Solyx and 4.2% post-I-stop-mini. Objective cure rates were 87.1% for Solyx and 91.7% for the I-stop-mini, with no statistical difference. Two patients in the Solyx group required repeat mid-urethral sling surgery. No cases of mesh erosion were noted in either of the groups.

CONCLUSIONS

Solyx and I-stop-mini are both effective at treating SUI. A short-tape single-incision sling device (Solyx) resulted in more voiding dysfunction than the adjustable-length device (I-stop-mini). TRS helps to resolve postoperative voiding dysfunction.

A systematic review and meta-analysis of single-incision mini-slings (MiniArc) versus transobturator mid-urethral slings in surgical management of female stress urinary incontinence

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.

Stress urinary incontinence surgery with sling MiniArc: a 4-year results

OBJETIVES

The aim of this publication is to describe retrospectively the results of the surgical technique of AMS MiniArc for the treatment of female urinary incontinence, evaluate its results at 4 years follow-up.

MATERIAL AND METHODS

We present a retrospective cohort study of 135 patients, 110 (81.5%) had urinary incontinence and 25 (18.5%) mixed urinary incontinence. All these procedures were performed with local anesthesia and in "out patient surgery". Patients were monitored in the outpatient clinic at 6 months (control 1), one year (control 2) and annually (control 3, 4, and 5). During the following up, clinical history was made in every woman with ICIQ-SF questionnaire, that included a fourth question to evaluate the degree of satisfaction after surgery, as well as physical examination. We considered objective cure when negative stress with full bladder. We use the SPSS program (V19.0) for statistical analysis of the results.

RESULTS

The mean follow-up was of 59 months (range from 33 to 72 months). When evaluating the success rate of anti-incontinence surgery, 86.7% of patients showed objective cured (80.8% with MUI and 89.2% with SUI). The ICIQ-SF decreased average of 12.7 points, 85.7% patients were very or fairly satisfied.

CONCLUSION

The AMS MiniArc is an optim anti-incontinence procedure a medium term. But the results should be interpreted with caution given the limitations of the study.

Ultrasonography and clinical outcomes following surgical anti-incontinence procedures (Monarc vs Miniarc)

OBJECTIVE

To evaluate the ultrasound morphology and its clinical outcome among women who had undergone Miniarc™ vs Monarc™ in the treatment of stress urinary incontinence (SUI).

STUDY DESIGN

This was a prospective study on 140 patients with USI and undergone either Miniarc or Monarc surgery. From March 2010 to December 2011, patients with clinically SUI and urodynamic stress incontinence (USI) were included in the study. Objective cure of SUI was defined as no urinary leakage on provocative filling cystometry and 1-h pad test of <2 g. Subjective cure of SUI was the negative response to UDI-6. Introital ultrasound at one-year explored the sling and bladder neck's position, mobility, sling tension, percentile of urethra where the sling was located and urethral kinking.

RESULTS

Postoperative data was available from 130 women. The ultrasound objective data for successful treatment post-operative follow-up was available from 119 women (46 Monarc, 73 Miniarc), the rest failed to follow-up. A bladder perforation was diagnosed in the Monarc group and 15 cases (7.1% of Monarc and 16.3% of Miniarc, p=0.082) of urinary retention was reported due to over-tensioning of the sling, majority of cases came from the Miniarc group. At rest and during Valsalva, analogous distances of the bladder neck and sling as well as the center of the urethral core were similar for both procedures. In both groups, shortest (Us) and longest diameters (Ul) of the urethral core were comparable at Valsalva which was significantly shorter and longer, respectively, compared to the values at rest. Sling position and percentage of urethral kinking were similar. Statistical analysis failed to detect any significant difference between the two groups with regards to the objective and subjective cure (p>0.05).

CONCLUSIONS

In conclusion, a Miniarc and Monarc exhibit similar mechanism of action with comparable subjective and objective clinical outcomes. Majority of urethral impingement was noted in the Miniarc group. A higher maximum urethral closure pressure (MUCP), longer resting Ul, and shorter resting Us suggested these observations. Postoperative ultrasonographic evaluation may give a promising future perspective for the evaluation of sling tension.

The introduction of mid-urethral slings: an evaluation of literature

INTRODUCTION AND HYPOTHESIS

The objective of this study was to evaluate the degree and reliability of evidence used by manufacturers before the introduction of mid-urethral slings (MUS) onto the commercial market. Furthermore, minimum standards for marketed slings are recommended by evaluating recent suggestions for the introduction of gynecological meshes.

METHODS

A systematic literature search was conducted using PubMed and commercial internet search engines in order to identify slings introduced by the industry over the last decade. Moreover, manufacturers were contacted by email, mail, and phone to provide data from before the introduction of the slings onto the commercial market. Once contact had been initiated, a 6-month deadline was set for data collection.

RESULTS

Forty-one slings introduced between 1996 and 2012 were identified. Ten slings were described in a total of 20 studies with sample sizes varying from 10 to 368. The 41 MUS were produced by a total of 19 different companies. Seven companies never responded to recurrent emails, phone calls or other means of attempted contact. Thirty-one slings (76%) remained without any comparative pre-launch data.

CONCLUSIONS

Mid-urethral slings were often introduced without any scientifically proven basis or pre-launch research. The US Food and Drug Administration and the European authorities should undertake immediate action by imposing strict rules before the launch of new MUS comparable with those recently suggested for meshes used in vaginal prolapse surgery.

Incontinence and Chronic Illness

Objetivo: explorar la producción y contenido de la información disponible a nivel mundial sobre el abordaje de la incontinencia urinaria (IU) e incontinencia fecal (IF) y su relación con la enfermedad crónica (EC). Materiales y métodos: a partir de una revisión de literatura en las bases de datos Cinahl, Ovid, Scielo, Medline y Psychoinfo, entre los años 2009 y 2012, bajo los descriptores de incontinencia urinaria e incontinencia fecal, en combinación con enfermedad crónica, con su traducción al inglés, se identificaron, analizaron y clasificaron los planteamientos sobre el tema de la incontinencia según relevancia para la comprensión de la misma en la situación de EC. Resultados: se presentan los estudios encontrados clasificados en cinco grandes grupos sobre IU e IF que incluyen los que ilustran la magnitud del problema por su frecuencia y tipología, los que establecen relación directa entre la incontinencia y la EC, los que describen otros factores asociados con la incontinencia y con la EC, los que abordan la forma de valorar la incontinencia y los que dan aportes respecto al manejo de la IU o IF en la EC. Conclusiones: la literatura tiene abundante producción científica en sus dos últimos años y a nivel mundial sobre la IU pero no en igual proporción sobre la IF. Existen modelos para la valoración, medición y comprensión del fenómeno así como para la intervención y atención puntual sobre la misma. No se reportan abordajes integrales al problema de la IU e IF en personas con EC.

What is the best indication for single-incision Ophira Mini Sling? Insights from a 2-year follow-up international multicentric study

INTRODUCTION AND HYPOTHESIS

The Ophira Mini Sling System involves anchoring a midurethral, low-tension tape to the obturator internus muscles bilaterally at the level of the tendinous arc. Success rates in different subsets of patients are still to be defined. This work aims to identify which factors influence the 2-year outcomes of this treatment.

METHODS

Analysis was based on data from a multicenter study. Endpoints for analysis included objective measurements: 1-h pad-weight (PWT), and cough stress test (CST), and questionnaires: International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) and Urinary Distress Inventory (UDI)-6. A logistic regression analysis evaluated possible risk factors for failure.

RESULTS

In all, 124 female patients with stress urinary incontinence (SUI) underwent treatment with the Ophira procedure. All patients completed 1 year of follow-up, and 95 complied with the 2-year evaluation. Longitudinal analysis showed no significant differences between results at 1 and 2 years. The 2-year overall objective results were 81 (85.3%) patients dry, six (6.3%) improved, and eight (8.4%) incontinent. A multivariate analysis revealed that previous anti-incontinence surgery was the only factor that significantly influenced surgical outcomes. Two years after treatment, women with previous failed surgeries had an odds ratio (OR) for treatment failure (based on PWT) of 4.0 [95% confidence interval (CI) 1.02-15.57).

CONCLUSIONS

The Ophira procedure is an effective option for SUI treatment, with durable good results. Previous surgeries were identified as the only significant risk factor, though previously operated patients showed an acceptable success rate.

Treatment of female stress urinary incontinence using suburethral slings: comparative, retrospective, observational study of two surgical techniques

OBJECTIVE

The treatment of female stress urinary incontinence has undergone a revolution in recent years due the emergence on the market of suburethral slings. The aim of this study is to compare two surgical techniques for treating stress urinary incontinence: Monarc™ (transobturator suburethral sling) and MiniArc(®) (single-incision suburethral mini-sling).

MATERIAL AND METHODS

Comparative, retrospective, observational study from January 2005 to December 2011 on 317 women diagnosed with stress urinary incontinence. Of these, 214 were treated with the Monarc™ transobturator suburethral sling, and 103 were treated with the MiniArc(®) mini-sling. The results were treated with SPSS v.15 software, and the statistical significance was P≤.005.

RESULTS

The two patients groups were homogeneous in terms of age, number of births, presence of urgency urinary incontinence and prior hysterectomy. There were significant differences in hospital stay, surgical time and early complications in favour of the MiniArc(®), technique, but overall there were no significant differences in the late complications. Some 84% of the patients treated with the Monarc™ transobturator sling were cured compared with the 72% of patients in whom we implanted a MiniArc(®), a difference that was statistically significant.

CONCLUSION

We need to perform more high-quality, prospective and randomised studies with larger numbers of patients and longer follow-up times to confirm or disprove the difference that we found in the success rate for the Monarc™ transobturator suburethral sling.
