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

Local anesthesia for Altis® single incision sling in women with stress urinary incontinence

OBJECTIVE

Local anesthesia for single incision slings has shown a good objective and subjective cure rate in women with stress urinary incontinence. The aim of the present study was to verify the efficacy and safety of local anesthesia during Altis® single incision placement.

MATERIAL AND METHODS

One hundred sixty-six consecutive patients (83 patients for each group: local resp. spinal anesthesia) were selected from our database for this retrospective study among women who underwent an Altis® implantation for SUI from September 2016 to June 2021, after unsuccessful previous conservative treatment. Primary endpoints were objective and subjective cure rates; secondary endpoint was the evaluation of complications linked to this procedure.

RESULTS

A total of 155 included patients completed our 12 months follow-up. Baseline characteristics were similar between the groups. Operative time (percentage difference of 50%; p < 0.05) and the Intraoperative Difficulty Scale resulted lower in spinal patients. No differences were found between populations in terms of objective (cough stress test and urodynamics) and subjective (PGI-I and FSDS questionnaires) cure rate and postoperative complications.

CONCLUSION

Local anesthesia for Altis® implantation could be considered a safe alternative to spinal anesthesia and an effective opportunity to avoid general anesthesia, increasing the possibility of outpatient implantation of this sling system.

Ambulatory MiniArc Precise Sling under Local Anesthesia for Stress Urinary Incontinence: Feasibility and Outcome

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 1^st 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.

Does the design of mini slings anchoring systems really matter? A biomechanical comparison between Mini Arc™ and Ophira™

INTRODUCTION AND HYPOTHESIS

Currently, a sling implant is the standard treatment for stress urinary incontinence in women. To be effective, they require an adequate anchoring system. The aim of this study is compare biomechanical features of fixation systems of two mini slings models available on the market (Ophira™ and Mini Arc™) through a tensile test.

MATERIALS AND METHODS

Anchoring devices of each sling were surgically implanted in abdominal wall of 15 rats divided into three groups of five animals which were arranged according to the date of post implant euthanasia on 7, 14 and 30 days. Abdominal walls of rats were extracted on bloc containing the anchoring system and were submitted to a tensile strength test to measure the maximum load and elongation until device avulsion from the tissue. The results were compared using Student test t and a 5% cut off was considered significant.

RESULTS

The Ophira™ mini sling fixation system demanded a greater maximum load and developed a longer stretch for avulsion from the implanted site at all moments evaluated (p value less than 0.05).

CONCLUSION

There were significant differences in fixation patterns of the anchoring systems, which were exclusively related to their designs. The Ophira™ mini sling fixation device provided better fixation to the abdominal wall of rats compared to the Mini Arc™ device, even in the late post implant period.

Medium-term results of Mini-arc for urinary stress incontinence in ambulatory patients under local anesthesia

OBJECTIVE

To evaluate the medium-term outcome and patient's satisfaction after Single-incision mini-sling (SIMS) procedure done under local anesthesia in ambulatory set up for patients with stress urinary incontinence (SUI).

MATERIALS AND METHODS

This is a retrospective cohort study, including all patients submitted to SIMS procedure for SUI with MiniArc (AMS, U.S.A) without concomitant surgery between January 2011 and March 2013. Patients were followed up during 12 months after surgery and once a year subsequently. Telephone interviews were conducted to evaluate patient satisfaction. Outcome masseurs included: SUI cure rate, urinary urge incontinence (UUI) cure rate in patients with mixed urinary incontinence (MUI), intra and post-operative complications and patient satisfaction.

RESULTS

Ninety-three patients were included with mean follow-up of 23 months. Fifty percent had MUI with predominant SUI. The cure rates of SUI (objective and subjective) were 89%. UUI was cured in 40% of patients. No major complications occur, neither voiding obstruction or groin pain. Telephone interviews conducted after 26 months on average revealed high satisfaction rate from the procedure (8.8 out of 10) and from the local anesthesia. Visual analog scale (VAS) rating was low during and after the procedure (2.38 and 2.69 respectively).

CONCLUSIONS

The SIMS procedure is safe and highly effective for SUI and it can be performed successfully under local anesthesia in an ambulatory setup.
