Comparison of outcomes of Burch colposuspension and transobturator tape and single incision needleless procedures (DynaMesh®-SIS minor) for the surgical treatment of female stress urinary incontinence patients who underwent combined pelvic reconstructive surgery or hysterectomy

PURPOSE

Women with stress urinary incontinence (SUI) often require combined pelvic reconstructive surgeries because of shared risk factors of pelvic organ prolapse. The purpose of this study was to evaluate efficacies of Burch colposuspension, transobturator tape (TOT), and single-incision needleless (DynaMesh^®-SIS minor) procedures in patients with SUI who also underwent combined pelvic reconstructive surgery or hysterectomy.

METHODS

We performed this retrospective cohort study that comprising 122 patients who either underwent Burch colposuspension (n:43), TOT (n:40), or SIS (n:39) procedures along with pelvic reconstructive surgery or hysterectomy between January 2010 and July 2018. During the clinical follow-up, we analyzed cure rates, and surgical success rates of SUI surgery, quality of life, and symptom severity by IIQ-7, UDI-6, SSI, SSQ-8, OAB-V8, and PGI-I scale scores. The primary outcome was surgical success, whereas secondary outcomes included complications and patient-reported outcomes in the quality of life.

RESULTS

We found that surgical success rates were higher in Burch group than SIS group and higher in TOT group than in SIS group (88.4% vs 61.5% and 87.5% vs 61.5%, p = 0.003). The quality of life was lower in SIS group than in Burch group.

CONCLUSIONS

Both Burch and TOT are effective procedures in patients with SUI who require additional pelvic surgeries. Although surgical outcomes of SIS procedure in patients with SUI who underwent concomitant pelvic surgeries in our study were not promising, further studies with SIS are needed to clarify these observations.

TVT Abbrevo and Miniarc suburethral sling in women with stress urinary incontinence - A randomised controlled trial

INTRODUCTION

Single incision slings (SIS) were introduced in an attempt to decrease the complications associated with retropubic and transobturator slings. The TVT Abbrevo is a modification of the TVT-O with a reduced length and less immediate postoperative pain. The Miniarc SIS has been shown to be equivalent to outside-in transobturator sling, Monarc at 12 month follow-up.

OBJECTIVE

To evaluate objective and subjective outcomes of MiniArc SIS and TVT Abbrevo midurethral sling (MUS) in women with stress urinary incontinence.

METHODS

Female subjects who were assessed and referred for stress urinary incontinence surgery were eligible to participate in this study. Exclusion criteria included women with intrinsic sphincter deficiency previous failed midurethral or fascial sling, untreated detrusor overactivity or significant voiding dysfunction. Patients' randomisation was performed with computer-generated blocks of 4-8, with concealed allocation. Assuming an objective cure rate of 90% for TVT AbbrevoTMwith a power of 80%, a sample size of 79 in each arm was required to detect a clinical difference of 15%, using a one sided alpha of 0.05. The target recruitment number was 220 allowing for an attrition rate of 15%. Institution ethics approval (11261B) was obtained and the trial was registered with the Australian New Zealand Clinical Trials Registry (ACTRN12611001151921). Routine preoperative assessment was conducted for objective data, whilst patient reported outcome tools (PRO) were utilised for subjective outcomes. These include ICIQ UI SF, ICIQ OAB, IIQ7, EQ5D, PISQ12, PGIs & PGII. TVT AbbrevoTM or MiniarcTMwere performed in a standardized fashion, together with any concomitant prolapse surgery. Review was conducted at 6 weeks and at 6 and 12 months. Objective cure was defined as a negative cough stress test with a comfortably full bladder. Subjective cure was defined as no report of leakage with physical exertion. All Data was collected and outcomes were analysed statistically.

RESULTS

Between February 2011 and January 2016,a total of 246 women were randomized to receive MiniArc (121) or TVT Abbrevo (125). Baseline characteristics were clinically balanced in both groups. At 6 months subjective (94.4% vs 95.7% p=0.74) and Objective (92.9% vs 95.9% p=0.49) cure rates were high and not statistically different. At 12 months there were also no differences in subjective (73.6% vs 76.9% p=0.73) or objective (90.5% vs 96.0% p=0.21) cure rates. No differences were found in functional outcomes or when adjusted for potential confounding factors such as age, parity, BMI or menopausal status.

CONCLUSION

We found no significant differences in subjective and objective cure rates at 6 and 12months between MiniArc and TVT Abbrevo.

Single incision slings: Past, present, and future

Pubovaginal slings have become the gold standard to treat stress urinary incontinence. Traditionally, the sling referred to a suspensory that was placed under the urethra and brought through the retropubic space and anchored on either side of the midline. Since this original concept, there have been many materials used for the sling, and there have been many different anchoring approaches. Most agree that one of the best materials is polypropylene mesh. However, the means of anchoring the device and where best to have this anchorage placed is debatable. The options for anchoring simply include using darts vs not to hold the sling in place. The location of this anchorage, on the other hand, is much more controversial. The main locations are retropubic, transobturator, and via a single incision. The obturator and retropubic slings have become the standard of care over time. The single incision sling, on the other hand, is starting to be more acceptable which has resulted in it being used more frequently. The single incision relies on mainly anchoring the sling through the obturator internus muscle with possible inclusion of the obturator membrane. The purpose of this review article is to present the data that exists for the use of the single incision sling.

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.

Single incision sling (Ajust™) for the treatment of female stress urinary incontinence: 2-year follow-up

OBJECTIVE

The primary outcome of this study was to evaluate the subjective and objective outcomes of an adjustable Single Incision Sling (Ajust™ C.R. Bard Inc., New Providence, NJ, USA) for the treatment of SUI, with a 2-year follow-up. The secondary outcome was to evaluate the safety of this procedure and the impact of this mini-sling on the filling and voiding phases of the bladder.

STUDY DESIGN

In our prospective multicenter study we included 95 females with a clinical symptomatic and urodynamic diagnosis of primary SUI, and unsuccessful previous conservative treatment. Cure rate was evaluated objectively, using a standardized cough stress test and subjectively using the patient global impression of improvement. The King's Health questionnaire was used to evaluate quality of life (QoL). Urgency was evaluated using the patient perception of intensity of urgency scale. Complications were assessed intra-, peri- and post-operatively. All patients underwent urodynamic studies pre-operatively and at 6 months. The McNemar chi-square test was used to compare categorical variables, the paired t-test for continuous parametric variables, and the Fisher exact test for continuous non-parametric variables. A logistic regression model and odds ratios (with 95 percent confidence intervals) were used to assess the independent prognostic value of four variables for the outcome (age, parity, body mass index and menopausal status).

RESULTS

92 Patients completed the 2-year follow-up. The objective cure rate was 83.7% and the subjective cure rate was 81.5%. De novo urgency was present in 9 patients (9.8%) and was associated with de novo urge incontinence in 6 patients (6.5%). Only 1 patient with de novo urge incontinence showed de novo detrusor overactivity. Regarding QoL, the King's Health Questionnaire indicated a statistically significant improvement in all domains except sleep. We observed no intraoperative complications. Post-operatively 1 patient referred pain in the right leg, 3 patients had mesh extrusions, 1 patient had recurrent urinary tract infections. Post-operative urodynamics showed a statistically significant increase of detrusor pressure at maximum flow and a reduction of maximum flow rate. No patients were obstructed according to the Blaivas and Groutz nomogram.

Single incision mid-urethral slings: impact of obesity on outcomes

OBJECTIVES

To assess the potential impact of obesity on the success rate of single incision slings (SIS).

STUDY DESIGN

This was a retrospective cohort study of women who underwent the SIS procedure for primary stress urinary incontinence. Women were divided into three different groups by body mass index (BMI) according to the WHO classification. The International Consultation on Incontinence-short form (ICIQ-SF), Women Irritative Prostate Symptoms Score (W-IPSS), Patient Global Impression of Severity (PGI-S) and Patient Global Impression of Improvement (PGI-I) questionnaires were used. Objective and subjective outcomes were the primary outcome measures of the study. SPSS software was used for data analysis.

RESULTS

206 patients who underwent the SIS procedure were reviewed. At 1 year follow-up there were 196 women available for the analysis: 69 were normal weight subjects, 91 overweight and 36 obese. Patients in all BMI groups reported a significant improvement in their condition. Nevertheless there was a trend towards lesser objective efficacy of SIS with increasing body weight, with a significant difference between obese women and normal subjects: 75% vs 91.3%, p=0.049; OR 3.74 (95% CI 1.19-11.76). Analysis of the ICIQ-SF and PGI-I showed significant lower mean ± SD improvement in obese women when compared with their normal or overweight counterparts, together with a significantly lower number of obese patients reporting themselves as very much improved or much improved.

CONCLUSIONS

Single incision slings seem to be an effective treatment regardless of BMI, but obese women had nearly 4 times the odds of objective failure as compared to normal weight women.
