Single incision mini sling for the treatment of urodynamic stress incontinence: Surgical outcomes and preoperative predictors of failure

OBJECTIVE

To evaluate the surgical outcomes and predictors of failure of Single Incision Mini Sling (Ophira) in women with urodynamic stress incontinence.

MATERIALS AND METHODS

Records of 115 women underwent anti-incontinence procedure using Ophira Mini Sling from June 2019 to September 2020 reviewed. Subjective evaluation was assessed using validated IIQ-7, UDI-6, POPDI-6 and PISQ-12 questionnaires. Multichannel urodynamics, 1-h pad test and 72-h voiding diary was performed as objective evaluation. Primary outcome was the objective cure rate of negative urine leak on provocative filling cystometry and 1-h pad test weight <2 g, and subjective cure rate was negative response to question 3 of UDI-6. Secondary outcome was to identify risk factors associated with failure for Ophira.

RESULTS

Total of 108 women were evaluated. The objective cure rate was 91.7% with subjective cure rate of 86.1%. Comparison of clinical outcome shows significant improvement of USI post-operatively (p < 0.001) and reflected in 1-h pad test (p < 0.001). Improvement in all subjective evaluation parameters is seen except for POPDI-6. Failure of Ophira correlate significantly in women age >66 years, presence of asthma, pre-operative Intrinsic Sphincter Deficiency (ISD), and Maximum Urethral Closure Pressure (MUCP) value < 40 cmH20.

CONCLUSION

Ophira Single Incision Mini Sling is safe and effective treatment option for USI, showing high objective and subjective cure rates with low incidence of complications. Non-modifiable risks of age ≥66 years, asthma status, pre-operative intrinsic sphincteric deficiency and low maximal urethral closure pressure were the factors of failure for Ophira.

Safety and Efficacy of Single Incision Sling Versus Midurethral Sling in the Treatment of Stress Urinary Incontinence: A Randomized Controlled Trial

IMPORTANCE

This study compares the long-term efficacy and safety of an innovative single-incision sling (SIS) with the inside-out transobturator tape (TOT) sling in the treatment of female stress urinary incontinence.

OBJECTIVES

Women with urodynamic stress urinary incontinence were randomized to either SIS or TOT groups and followed up for 4 years. The primary outcome was objective cure defined with a negative cough stress test result. Secondary outcomes involved subjective cure reported via patient's satisfaction scale, surgery complications, postoperative de novo urgency, and patient's life quality.

STUDY DESIGN

This is a randomized noninferiority controlled trial.

RESULTS

A total of 168 women were randomized (84 in both groups). After 4-year follow-up, 130 patients were analyzed (66 in the SIS group and 64 in the TOT group). The objective (86.4% vs 84.4%; risk difference [95% confidence interval], 0.020 [-0.101 to 0.141]; P = 0.807) and subjective cure rates (83.3% vs 81.3%; risk difference [95% confidence interval], 0.020 [-0.111 to 0.151]; P = 0.821) were similar with the SIS and TOT groups. Both procedures were associated with low complication rates. Repeated surgery rates were 7.6% in the SIS group and 6.3% in the TOT groups. The mesh exposure rate was 1.5% for the SIS group and 3.1% for the TOT group. Incidence of de novo urgency did not vary between TOT and SIS patients. Both groups registered significant life quality improvement.

CONCLUSION

After long-term follow-up, anti-incontinence SIS surgery proved noninferior to the inside-out TOT procedure in terms of objective and subjective cure rates.

Preliminary report of post-Ophira mini sling implantation voiding pattern: What to learn from pressure-flow studies?

BACKGROUND

The study is amined to correlate the voiding pattern after successful mini sling Ophira implantation with postoperative symptoms and satisfaction, in addition to identifying obstructions.

MATERIALS AND METHODS

From 2012 to 2015 in a single institution, all consecutive patients who had stress urinary incontinence treated by using the mini sling Ophira had a pre- and 12 months postoperative urodynamic test. The International Consultation on Incontinence Questionnaire - Urinary Incontinence - Short Form (ICIQ-UI-SF) and the International Consultation on Incontinence Questionnaire - Overactive Bladder (ICIQ-OAB) translated into Portuguese, were given. Patients were objectively considered cured when presenting no urinary incontinence at the Valsalva test and subjectively cured when the ICIQ-UI-SF was zero.

RESULTS

Questionnaire scores were obtained from 29 patients and urodynamic data from 20 patients. Mini sling Ophira implantation resulted in a significant improvement of urinary symptoms evidenced by a significant mean reduction in ICIQ-UI-SF from 16 to 5 (p < 0.0001) and ICIQ-OAB from 8 to 4 (p = 0.0001). The subjective and objective cure rates were 55% and 45%, respectively. The urodynamic changes were not related to success even when adjusted for age, hormonal status, or anterior pelvic organ prolapse. The mean maximum flow decreased to 4.9 mL/s (95% CI: 0.62-10.8; p = 0.035), and the mean detrusor pressure at maximum flow increased to 11.4 cmH2O (95% CI: 4-18; p = 0.0078).

CONCLUSIONS

Mini sling Ophira implantation decreased maximum urinary flow and increased the detrusor pressure at the maximum urinary flow and these urodynamic changes were not related to success.

Randomized controlled trial comparing mini-sling with transobturator sling for the treatment of stress urinary incontinence

INTRODUCTION AND HYPOTHESIS

Stress urinary incontinence (SUI) is the involuntary loss of urine on effort and is a condition that negatively interferes with various aspects of a woman's life. This study aimed to demonstrate the non-inferiority of the less invasive single-incision mini-sling (SIMS) method in objective and subjective cures in relation to tension-free transobturator tape (TOT) in two analyses, per protocol and intention to treat, and secondarily to evaluate complications and quality of life.

METHODS

This study was a randomized controlled trial (RCT). Participants in this study included 105 women with a clinical diagnosis of stress predominant urinary incontinence and urodynamic results demonstrating SUI and absence of detrusor overactivity. Patients were evaluated pre- and postoperatively through anamnesis, physical examination, urinalysis, urine culture and susceptibility testing, simplified pad test, the Urinary Incontinence-Specific Quality of Life Instrument (I-QOL) and Urogenital Distress Inventory Short Form (UDI-6).

RESULTS

Regarding the objective cure, SIMS was non-inferior to TOT (p < 0.05). However, the same was not found for the subjective cure (p > 0.05). There were no differences in the complication rates (p > 0.05). However, in the TOT group, bladder perforation (2.4%), tape exposure (2.4%) and urinary retention occurred, lasting > 7 days (2.4%). In both groups, there was improvement in quality of life after surgery, without significant differences (p > 0.05).

CONCLUSIONS

The non-inferiority of SIMS in relation to TOT was only demonstrated in the objective cure. There were no significant differences between groups regarding complications and quality of life.

Long-term outcomes and quality of life effects of single incision mini sling procedure in stress urinary incontinence patients

OBJECTIVE

We aimed to evaluate the long-term outcomes and quality of life of patients who underwent single incision minisling (SIMS) procedure.

STUDY DESIGN

62 patients who were diagnosed with stress urinary incontinence (SUI) and received treatment with SIMS procedure (Ophira, Promedon, Argentina) were included in the study. Mean age was 50.73 ± 9.28 years and mean follow-up duration after surgery was 30.68 ± 7.52 months. Preoperative urological and gynecological features of the patients were recorded. Gynecological examination, pelvic ultrasonography, stress test, Q-tip test, cystometry were performed and incontinence and quality of life questionnaires (ICIQ-SF, IIQ-7, UDI-6, VAS-QOL, FSFI) were completed by all patients before and after the operation.

RESULTS

Stress urinary incontinence was observed in all patients during pre-op evaluations. 62 patients aged between 35-85 (mean age 50.73 ± 9.28) years were included and follow up duration ranged between 12-44 (average 30.68 ± 7.52) months. In regard to patient evaluations, 27 patients (43.5%) felt that the surgery was very effective, 25 (40.3%) felt surgery was effective and 10 (16.1%) did not report any difference after surgery. In the long-term postoperative follow up; 2 (3.2%) patients had dyspareunia and 7 (11.3%) patients had vaginal tape erosions which were diagnosed 2-40 months postoperatively. According to Q-tip test results, proximal urethral mobility was significantly decreased after surgery. All questionnaire scores were also significantly improved at post-operative evaluations. (P < 0.001) CONCLUSIONS: Our study confirmed that the Ophira mini sling technique provided high subjective cure rate and improved symptoms and quality of life in patients with SUI. These results suggest that the single incision mini sling procedure is an advisable alternative to other surgical procedures due to its low complication rates and ease of learning and applying the procedure. This procedure also demonstrated excellent tolerability, minimal pain, low morbidity and increased quality of life scores, in ICIQ-SF, IIQ-7, UDI-6, VAS-QOL, FSFI.

Single incision slings: Are they ready for real life?

AIM: To review of the efficacy and safety outcomes of different single incision slings (SIS) systems, also in comparison with traditional slings.

METHODS: A literature search was conducted in PubMed/MEDLINE database. The research was restricted to randomized and/or prospective trials and retrospective studies, published after 2006, with at least 20 patients with non-neurogenic stress urinary incontinence (SUI). The studies had to assess efficacy and/or safety of the SIS with a minimum follow-up of 12 mo. All the paper assessing the performance of tension free vaginal tape secur were excluded from this review. The final selection included 19 papers fulfilling the aforementioned criteria. Two authors independently reviewed the selected papers.

RESULTS: Four different SIS systems were analysed: Ajust^®, Ophira^®, Altis^® and MiniArc^®. The average objective cure rate was 88%. Overall no statistically significant differences were found between SIS and traditional mid-urethral slings (MUS) in terms of objective cure (all P > 0.005). Only one paper showed a statistically lower success rate in MiniArc^®vs Advantage^® slings (40% vs 90%) and higher rates of failure in the SIS group. Since there was a great variability in terms of tests performed, it was not possible to compare subjective cure between studies. The vast part of the studies showed no major complications after SIS surgery. We also observed very low reported pain rates in SIS patients. The RCTs on Ajust^® and MiniArc^®, showed better outcomes in terms of post-operative pain compared to MUS. None of the patients reported long- term pain complains.

CONCLUSION: SIS showed similar efficacy to that of traditional slings but lower short-term pain, complication and failure rates.

Heterogeneity in post-intervention prolapse and urinary outcome reporting: a one-year review of the International Urogynecology Journal

INTRODUCTION

This review aimed to examine post-intervention prolapse, incontinence, and overactive bladder outcome measures published in the International Urogynecology Journal over the previous year and to report on the heterogeneity in outcome reporting.

METHODS

All original article abstracts published in the print version of the International Urogynecology Journal in 2014 were reviewed for possible inclusion. Those reporting on prolapse and/or incontinence and/or overactive bladder outcomes following a urogynecological intervention were analyzed. Articles were reviewed for all reported outcomes. Outcomes were categorized as primary or secondary and objective or subjective.

RESULTS

Of 117 original articles published, 45 were reviewed. Among primary outcomes, 9 different outcomes were reported for prolapse and 11 for incontinence and overactive bladder. For prolapse, 6 different objective and 13 subjective outcomes were reported. For incontinence, 21 objective and 36 subjective outcomes were reported. Three different definitions were used for the outcome of "prolapse cure," 3 for "prolapse recurrence," and 4 for "stress incontinence cure." Several validated and non-validated questionnaires in addition to single unvalidated questions were used to measure subjective outcomes.

CONCLUSIONS

This research highlights the diversity in outcome reporting for prolapse, incontinence, and overactive bladder after an intervention in the last year of publications alone. This can lead to serious challenges in the generation of higher order evidence, such as systematic reviews and meta-analyses. As a subspecialty, we need to aim for more cohesive reporting so as to allow for robust comparison and evidence dissemination.
