Comparison of Clinical Efficacy and Urodynamic Changes Using Single-incision Slings (MiniArc ® vs. Solyx™) for the Treatment of Female Stress Urinary Incontinence. Gynecol Minim Invasive Ther 2021; 10:235-242. [PMID: 34909381 PMCID: PMC8613486 DOI: 10.4103/gmit.gmit_102_20] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2020] [Revised: 03/15/2021] [Accepted: 04/22/2021] [Indexed: 11/30/2022] Open
Abstract
Objective: To compare the clinical efficacy and urodynamic parameter changes between the MiniArc and the Solyx sling for the treatment of female urodynamic stress incontinence (USI). Materials and Methods: One-hundred and thirty (MiniArc n = 79, BS-Solyx n = 51) patients were included in this study. Cough stress test (ST), pad test (PT), Incontinence Impact short form Questionnaire (IIQ-7), Urogenital Distress Inventory six-item questionnaire (UDI-6), Sexual Questionnaire-Short Form (PIS-Q), and urodynamic parametric changes were assessed to determine objective and subjective outcomes following the procedure. Objective cure was defined as negative ST and PT <2 g and subjective cure was defined as “No” to the answer of UDI-6 Question #3. Predictors of surgical failure were also determined. Results: All Solyx users, as opposed to 91.1% of MiniArc patients, obtained objective cure at postoperative 3 months (P = 0.042). No significant difference in subjective cure rates (93.7% vs. 90.2% at 3-months (P = 0.513); 89.9% vs. 80.4% at 1 year for Solyx and MiniArc patients, respectively (P = 0.126)) and improvement scores in UDI-6 and IIQ-7 were observed. The Solyx group incurred more de novo urgency (17.6% vs. 6.3% at 3 months (P = 0.042); 23.5% vs. 7.6% at 1 year (P = 0.01)). Both procedures yielded significant decrements in maximal urethral closure pressure (P < 0.001) and average flow rate (P = 0.015). The preoperative PT and sling type were strong predictors of surgical failure, where the Solyx tape reported lower odds (odds ratio = 0.174, P = 0.02) compared to the MiniArc sling. Conclusion: Single-incision mini-slings are safe and effective treatment for female USI. The Solyx SIS demonstrated superiority over the MiniArc in this study based on its higher objective cure rate and lower risk for surgical failure.

Preliminary report of post-Ophira mini sling implantation voiding pattern: What to learn from pressure-flow studies? Curr Urol 2021; 15:181-184. [PMID: 34552460 PMCID: PMC8451316 DOI: 10.1097/cu9.0000000000000026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2020] [Accepted: 04/15/2020] [Indexed: 12/01/2022] Open
Abstract
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.

Abstract
Background: Stress urinary incontinence is one of the most common types of incontinence in premenopausal women, accounting for almost 50% of such cases. Mid-urethral slings are currently the most widely used surgical method for stress urinary incontinence. This study aimed at comparing the efficacy, complications, urodynamic changes and the sexual function status between mini-sling surgery and transobturator tape to help us select the best method in such patients. Method: In this randomized controlled trial, 80 cases were studied and randomly assigned to either the mini-sling or transobturator tape group (n = 40). A full medical history was taken and the Q.tip and cough tests were performed for each patient to record their urinary incontinence and hypermobility. Abdominal and pelvic ultrasound study was requested by specifying PVR and urodynamic testing. The International Consultation on Incontinence Modular Questionnaire-6 was filled by the patients and the Female Sexual Functioning Index questionnaire by the physician. The patients were followed-up 8 weeks after discharge by urodynamic tests, ultrasound study, and the International Consultation on Incontinence Modular Questionnaire test. Results: The mean age, body mass index, and parity were not significantly different between the two groups. The mean surgical time, amount of bleeding, hospitalization period, and pain index were significantly less in the mini-sling group. The International Consultation on Incontinence Modular Questionnaire and Female Sexual Functioning Index indices before and after surgery showed no significant difference between the two groups. The difference in urodynamic test parameters was also insignificant. Conclusion: In the mini-sling method which is a less invasive method compared to transobturator tape, the intraoperative bleeding, surgical time, hospitalization period, pain, and surgical complications were far less while its efficacy was similar to transobturator tape; therefore, it is recommended in treating stress urinary incontinence among women.

Abstract
Objective To evaluate the association between the length of the female urethra and urodynamic study (UDS) parameters in patients presenting with stress urinary incontinence (SUI). Patients and methods We retrospectively enrolled 391 women who underwent a transobturator adjustable tape sling implantation for the management of SUI between April 2009 and March 2016. All patients underwent a physical examination and UDS. Filling cystometry data that were evaluated included the Valsalva leak point pressure, and the cough leak point pressure. The maximal urethral closure pressure, the functional urethral length (FUL), and the length of the continence zone (LCZ) were measured using the urethral profile obtained from the UDS. The anatomical urethral length (AUL) was measured intraoperatively using a Foley catheter. We calculated the LCZ/FUL ratio to determine the anatomical continence length for this study. Results We noted that 299 patients completed the study. The mean AUL was 26.25±3.59 mm. The mean FUL and LCZ were 41.37±15.05 mm and 24.15±13.90 mm, respectively. The mean LCZ/FUL was 0.57±0.19. Using the Pearson correlation coefficient, we observed that the AUL showed a correlation with the FUL (0.168, P=0.034), the LCZ (0.212, P=0.007), the LCZ/FUL ratio (0.190, P=0.016), the Valsalva leak point pressure (0.223, P=0.005), the cough leak point pressure (0.215, P=0.006), and the maximal urethral closure pressure (0.178, P=0.043). Conclusion Our results show that the AUL in women is associated with UDS parameters relating to SUI.

Abstract
AIM To demonstrate the clinical and urodynamic outcomes of transobturator sling (TOT) with or without concomitant prolapse surgery for the treatment of urodynamic stress incontinence (USI). METHODS We recruited 143 consecutive patients diagnosed with USI, who received outside-in TOT in a university hospital. Preoperative and postoperative examinations were implemented using structured urogynecological questionnaires, pelvic organ prolapse quantification examination and urodynamic testing. Patient demographics, surgical and urodynamic results were compared between TOT with and without concomitant prolapse surgery. RESULTS The mean follow-up was 30.1 months (range 12-57). Postoperative stress urinary incontinence (SUI) occurred in 10 (7%) patients at 3 months and 10 (7%) patients at 12 months postoperatively. There was no significant difference in prevalence of postoperative SUI between groups of TOT only and TOT combined with pelvic surgery. Preoperative urodynamic results demonstrated that TOT only (n = 96) had a higher maximal flow rate and a lower residual urine amount when compared to TOT combined with pelvic surgery (n = 47). A significant decrease in maximal urethral closure pressure (MUCP) was found in 119 patients who received postoperative urodynamic examination. In comparison with preoperative urodynamic data, postoperative urodynamic results showed a significant decrease in MUCP in the TOT combined with prolapse surgery group, but no significant urodynamic changes in the group of TOT only. CONCLUSION Both TOT and TOT combined with prolapse surgery can be effective in correcting SUI in patients with USI 12 months postoperatively, with significant changes in MUCP.

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.

Abstract
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.

Abstract
BACKGROUND Midurethral sling procedures have become the prime surgical treatment for women with stress urinary incontinence (SUI). Single-incision mini-slings (SIMS) potentially offer similar efficacy with reduced morbidity. This international multicenter trial compared the efficacy and morbidity of a SIMS (MiniArc) and a transobturator standard midurethral sling (SMUS) (Monarc). OBJECTIVE To compare subjective and objective cure, morbidity, and surgery-related discomfort following SIMS and transobturator SMUS. DESIGN, SETTING, AND PARTICIPANTS Prospective randomized controlled trial with an initial follow-up period of 12 mo. Women with symptomatic SUI were eligible. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Primary outcome was subjective cure, defined as an improvement on the Patient Global Impression of Improvement (PGI-I). Coprimary outcome was the mean visual analog scale (VAS) pain score (0-100) during 3 d after surgery. Secondary outcomes were objective cure based on the cough stress test (CST), disease-specific quality of life determined by the Urogenital Distress Inventory (UDI-6) score, surgical parameters, and physical performance during recovery. Analysis was by intent to treat. Differences between the MiniArc and Monarc groups on dichotomous variables were chi-square tested and presented as relative risks (RR) with corresponding 95% confidence intervals. We hypothesized that MiniArc was noninferior to Monarc concerning subjective cure and superior concerning postoperative pain. RESULTS AND LIMITATIONS We randomized 97 women to MiniArc and 96 to Monarc. At 12-mo follow-up, subjective cure was 83% following MiniArc and 86% following Monarc (p=0.46). Objective cure was 89% following MiniArc and 91% following Monarc (p=0.65). The mean pain VAS score during the first three postoperative days was 9 following MiniArc and 22 following Monarc (Mann-Whitney U test, p<0.01). CONCLUSIONS At 1-yr follow-up, MiniArc was noninferior to Monarc with respect to subjective and objective cure and superior with respect to postoperative pain. PATIENT SUMMARY This 1-yr randomized clinical trial showed that MiniArc, a single-incision midurethral sling, is noninferior to Monarc, a transobturator sling, with respect to cure and superior with respect to pain and recovery.

Abstract
CONTEXT An updated systematic review and meta-analysis of randomised controlled trials (RCTs) comparing single-incision mini-slings (SIMS) versus standard midurethral slings (SMUS) in the surgical management of female stress urinary incontinence (SUI). OBJECTIVE To evaluate the clinical efficacy, safety, and cost effectiveness of SIMS compared with SMUS in the treatment of female SUI. EVIDENCE ACQUISITION A literature search was performed for all RCTs and quasi-RCTs comparing SIMS with either transobturator tension-free vaginal tape (TO-TVT) or retropubic tension-free vaginal tape (RP-TVT). The literature search had no language restrictions and was last updated on May 2, 2013. The primary outcomes were patient-reported and objective cure rates at 12 to 36 mo follow-up. Secondary outcomes included operative data; peri- and postoperative complications, and repeat continence surgery. Data were analysed using RevMan software. Meta-analyses of TVT-Secur versus SMUS are presented separately as the former was recently withdrawn from clinical practice. EVIDENCE SYNTHESIS A total of 26 RCTs (n=3308 women) were included. After excluding RCTs evaluating TVT-Secur, there was no evidence of significant differences between SIMS and SMUS in patient-reported cure rates (risk ratio [RR]: 0.94; 95% confidence interval [CI], 0.88-1.00) and objective cure rates (RR: 0.98; 95% CI, 0.94-1.01) at a mean follow-up of 18.6 mo. These results pertained on comparing SIMS versus TO-TVT and RP-TVT separately. SIMS had significantly lower postoperative pain scores (weighted means difference [WMD]: -2.94; 95% CI, -4.16 to -1.73) and earlier return to normal activities and to work (WMD: -5.08; 95% CI, -9.59 to -0.56 and WMD: -7.20; 95% CI, -12.43 to -1.98, respectively). SIMS had a nonsignificant trend towards higher rates of repeat continence surgery (RR: 2.00; 95% CI, 0.93-4.31). CONCLUSIONS This meta-analysis shows that, excluding TVT-Secur, there was no evidence of significant differences in patient-reported and objective cure between currently used SIMS and SMUS at midterm follow-up while associated with more favourable recovery time. Results should be interpreted with caution due to the heterogeneity of the trials included.

Abstract
INTRODUCTION AND HYPOTHESIS There are limited long-term efficacy data on single-incision slings. The primary aim of this study was to evaluate the success rate of a single-incision sling versus a retropubic mid-urethral sling for cure of SUI at 3 years' follow-up, in order to assess whether there is a deterioration in efficacy over time. The secondary aims were to assess re-operation rates for each procedure and to evaluate any differences in disease-specific quality of life. METHODS This study was a 3-year questionnaire-based follow-up of a randomised controlled trial of the Miniarc single-incision sling versus the Advantage retropubic mid-urethral sling. Patients were considered failures if they documented stress incontinence on the symptom domain of the King's Health questionnaire (KHQ) or had undergone repeat surgery for stress incontinence. RESULTS Follow-up was available from 35 out of 38 women in the single-incision sling group (92.1 %) and from 26 out of 33 in the retropubic mid-urethral sling group (79.0 %). The overall 3-year failure rate was 20 out of 38 (52.6 %) in the single-incision sling group and 3 out of 33 (9.0 %) in the retropubic mid-urethral sling group (odds ratio 10.0, 95 % confidence interval 2.6-38.4). In the single-incision sling group, the failure rate increased from 40.5 % at 6 months to 52.6 % at 3 years with corresponding figures of 3 to 9 % in the retropubic mid-urethral sling group. CONCLUSIONS In this study, there was a significantly higher 3-year failure rate for the single-incision sling versus the retropubic mid-urethral sling. Both procedures had reduced efficacy over time.
