Results on function and safety of the Safyre-t, a hybrid transobturator vaginal sling for the treatment of stress urinary incontinence

Incontinence outcomes in women undergoing retropubic mid-urethral sling: a retrospective cohort study comparing Safyre™ and handmade sling

Purpose

This study examined and compared efficacy, safety, satisfaction, and complications of the retropubic Safyre™ sling and a retropubic hand-made synthetic sling (HMS) in a short-, mid- and long-term follow-up.

Methods

We retrospectively reviewed a prospectively maintained database of women who underwent Safyre™ or HMS between March 7^ths 2005 and December 27^ths, 2017. Patients had first assessment (7-10 days), second (40-45 days), and third (sixth month) postoperatively. Between September and December 2018, patients who completed at least one year of surgery, received a telephone call. Follow-up compared quartiles of follow-up time to determine complications (Clavien-Dindo), success rates (International Consultation on Incontinence Modular Questionnaire for Urinary Incontinence Short Form – ICIQ-UI SF), and patient satisfaction.

Results

Three hundred fifty-one patients underwent surgery and 221 (63%) were evaluated after a median of 78.47 (± 38.69) months, 125 (55%) in the HMS, and 96 (45%) in the Safyre™ group. Higher intraoperative bladder injury was observed with Safyre™ (0% vs. 4.2%, p=0.034), and a tendency for urinary retention, requiring indwelling urinary catheter over 24 hours (2.4% vs. 8.3%, p=0.061). Both HMS (p<0.001) and Safyre™ (p<0.001) presented improvements on ICIQ-UI SF. There were no differences in satisfaction, subjective cure rates, ICIQ-UI SF, or complications between groups.

Conclusions

Both HMS and Safyre™ have similar satisfaction and subjective cure rates, with marked ICIQ-UI SF score improvement. Higher rates of intraoperative bladder injury were seen in patients who received Safyre™ retropubic sling.

Outcomes of Transobturator Tape Surgery with Safyre T® Slings for Female Stress Urinary Incontinence after 96 Months of Follow-Up

BACKGROUND/AIMS

To report the outcomes of transobturator tape (TOT) surgery with Safyre T® (Promedon, Argentina) slings for female stress urinary incontinence (SUI) at a 96- month follow-up.

METHODS

We conducted a clinical follow-up study of 153 patients diagnosed with SUI between January 2005 and December 2014. Patients were provided with detailed a priori information pertaining to the TOT procedure and were invited to attend follow-up visits at 1, 3, 12, 24, 48, 72 and 96 months. Follow-up visits included physical examination involving sling palpation, checking of the vaginal mucosa for erosion, cough test, as well as validated Urinary Distress Inventory-6 (UDI-6) and Incontinence Impact Questionnaire-7 (IIQ-7) questionnaires.

RESULTS

The overall objective success rates, based on cough test results, were 91.3% at 12 months, 86.8% at 48 months and 77.6% at 96 months. Similarly, the overall subjective success rate, based on the validated UDI-6 and IIQ-7 scales, was 77.6% at 96 months.

CONCLUSION

The cure rates achieved, following TOT treatment of SUI at 1-year follow-up, showed a statistically significant decline over an 8-year period, especially at months 48 and 96. © 2015 S. Karger AG, Basel.

[Sub-urethral sling in the treatment of female urinary incontinence: which? how?]

Review of the literature that formed the basis for drafting the guideline on the sub-uretral sling in the first-line surgical treatment of female stress urinary incontinence. Medline database query since the introduction of TVT on the questions of various chapters and sub-chapters of the present article. The use of tapes made of polypropylene monofilament exclusively, knitted, is recommended to the exclusion of any other material. Regarding the choice of procedure, the objective cure rate of transobturator and retro-pubic routes cannot be evaluated clearly because of vague evaluation criteria from one study to another. Without adequate clinical trials proving their efficacy and safety, the mini-bands can so far be recommended to treat female stress urinary incontinence. Moderate overweight does not affect the results of laying tape. In patients with severe obesity, surgery to correct obesity is even better than surgery for incontinence. Age is not a contra-indication. If the patient is young and nulliparous, it is reasonable to advise her to postpone surgery after her last pregnancy. In case of multiparous patient, the risk of vaginal delivery does not seem sufficient to suggest a cesarean section. To conclude, sub-urethral slings are the first-line surgical treatment of female stress urinary incontinence.

Demonstration of pelvic anatomy by modified midline transection that maintains intact internal pelvic organs

Gross dissection for demonstrating anatomy of the human pelvis has traditionally involved one of two approaches, each with advantages and disadvantages. Classic hemisection in the median plane through the pelvic ring transects the visceral organs but maintains two symmetric pelvic halves. An alternative paramedial transection compromises one side of the bony pelvis but leaves the internal organs intact. The authors propose a modified technique that combines advantages of both classical dissections. This novel approach involves dividing the pubic symphysis and sacrum in the median plane after shifting all internal organs to one side. The hemipelvis without internal organs is immediately available for further dissection of the lower limb. The hemipelvis with intact internal organs is ideal for showing the complex spatial relationships of the pelvic organs and vessels relative to the intact pelvic floor.

Foreign body reaction in vaginally eroded and noneroded polypropylene suburethral slings in the female: a case series

INTRODUCTION AND HYPOTHESIS

Aim of this study was to investigate the pattern of the foreign body reaction of macroporous polypropylene mesh (MPPM) used in females for the treatment of stress urinary incontinence and to compare this pattern between eroded and noneroded tapes.

METHODS

Ten explanted suburethral slings, five eroded and five noneroded, were examined immunohistochemically under light microscopy; the tissue reaction was compared between eroded and noneroded materials.

RESULTS

Eroded material showed a significantly higher accumulation of macrophages around the filaments of the mesh.

CONCLUSIONS

This is the first study comparing reaction around eroded and noneroded MPPMs and indicates a more intense tissue reaction around eroded mesh, when compared to noneroded material. More studies are needed to prove whether the detected foreign body reaction was the actual trigger for the erosion.

Sexual function after suburethral sling removal for dyspareunia

INTRODUCTION

Impact on sexual function has received little attention in the medical literature for a long time. Because of the site of insertion of permanent tension free vaginal tape (TVT) the G spot might be affected or the tape might interfere with arousal and sensory stimulation. Recent studies have reported varying degrees of sexual impairment after TVT insertion ranging from 0% to 15% including dyspareunia.

AIM

The aim of this study was to evaluate sexual function before and after suburethral sling removal due to postoperative female de novo dyspareunia. As a secondary outcome, general patients' satisfaction with their overall continence situation was assessed.

PATIENTS AND METHODS

Between December 2005 and December 2007, we included 18 female patients who complained of de novo dyspareunia after suburethral sling insertion for urinary stress incontinence. All patients filled in an FSFI questionnaire prior to sling removal and at 3 months postoperatively. Additionally, all women were asked to estimate their general satisfaction regarding their continence situation using a Visual Analogue Scale (VAS) from 0 to 10, with 0 being the least satisfying situation and 10 being the most satisfying situation. All patients underwent gynaecological examination including ICS-pelvic organ prolapse staging (ICS-POP score).

RESULTS

Of the 18 slings, ten were transobturator tapes (6 x TVT-O, 2 x Monarch, 2 x unknown) and eight were retropubic tapes (7 x TVT, 1 x SPARC). Desire, arousal, lubrication, satisfaction, and pain improved statistically significant. Orgasm scores were low with median scoring of 1.5 scores before and 1.0 scores after sling removal, and they did not change significantly after sling removal. The satisfaction rate deteriorated from a median of 7 (95% confidence interval [CI] 6.3-7.7) to a median of 4 (95% CI 3.7-5.1; p=0.99) but not statistically significant.

CONCLUSIONS

Sexual function in patients with de novo dyspareunia is likely to improve after sling removal but not in all domains. Bladder function may deteriorate.
