Impact of Single-Incision Sling Placement on Female Sexual Function in Women with Stress Urinary Incontinence

INTRODUCTION AND HYPOTHESIS

Stress urinary incontinence (SUI) is a common condition among women of childbearing age, often requiring surgical intervention. The midurethral sling (MUS), including first-generation tension-free vaginal tapes (TVT) and second-generation transobturator tapes (TOT, TVT-O), has long been the standard treatment. However, both approaches have associated risks, prompting the development of single-incision slings (SIS) as a third option. SIS have proven their efficacy in SUI treatment, but the impact of these slings on female sexual function specifically remains underexplored.

METHODS

A literature search was conducted using PubMed using the keywords "stress urinary incontinence," "midurethral slings," "single-incision slings," "female sexual function," and "dyspareunia."

RESULTS

The reviewed studies demonstrated that SIS generally maintain or improve sexual function postoperatively, but with varying impact on specific aspects of sexual function. While coital urinary incontinence often improved or resolved, new or worsened dyspareunia was reported in a significant number of patients.

CONCLUSION

SIS placement for SUI generally preserves or enhances sexual function, though individual aspects, such as dyspareunia, may worsen for some patients. Given that an important goal of SUI treatment is to improve quality of life, it is crucial to identify preoperative factors that will identify patients at risk of developing dyspareunia after surgery or are more likely to experience an improvement in sexual function. Further research is needed to better understand these predictors and optimize surgical outcomes for women undergoing SUI treatment with SIS.

Comparing combined paravaginal repair with pubocervical fascia plication versus standard anterior colporrhaphy for the treatment of stress urinary incontinence in women with anterior vaginal wall prolapse: a randomised controlled trial

BACKGROUND

Stress urinary incontinence (SUI) is prevalent among women, often occurring alongside anterior vaginal wall prolapse. This study compares the efficacy and safety of an improved vaginal wall repair technique with pubocervical fascia fixation versus standard anterior colporrhaphy for treating SUI in women with anterior vaginal wall prolapse.

METHODS

A single-centre, parallel-group, randomised controlled trial was conducted between September 2021 and June 2024. Women aged 40-70 years with symptomatic SUI and stage 2-3 anterior vaginal wall prolapse were randomised to either the improved repair group or the standard repair group. The primary outcome was patient-reported success at 12 months post-surgery, defined as 'very much improved' or 'much improved' on the Patient Global Impression of Improvement scale. Secondary outcomes included objective cure rates, quality of life scores, urodynamic parameters, anatomical outcomes, perioperative outcomes and adverse events.

RESULTS

A total of 102 women were randomised (51 in each group). At 12 months, the patient-reported success rate was significantly higher in the improved repair group (94.1% vs 78.4%, p = 0.019). The objective cure rate was also higher in the improved repair group (90.2% vs 74.5%, p = 0.038). Quality of life scores and urodynamic parameters showed greater improvements in the improved repair group. Anatomical success was achieved in 92.2% of the improved repair group compared with 80.4% in the standard repair group (p = 0.048). The improved repair technique was associated with longer operative time but lower estimated blood loss, shorter hospital stay and quicker return to normal activities. The overall complication rate was lower in the improved repair group (11.8% vs 23.5%, p = 0.043).

CONCLUSIONS

The improved vaginal wall repair with pubocervical fascia fixation demonstrates superior outcomes compared with standard anterior colporrhaphy, with higher patient-reported success rates, improved quality of life and fewer complications.

Long-Term Outcomes of the Altis® Single-Incision Sling: Up to 10 Years' Follow-up

INTRODUCTION AND HYPOTHESIS

Single-incision slings (SIS) have emerged as a less invasive alternative to conventional slings for stress urinary incontinence (SUI) treatment. However, long-term efficacy and safety results remain uncertain owing to a lack of studies.

MATERIAL AND METHODS

A retrospective review of 155 patients treated with Altis® for SUI between February 2012 and June 2017, held in 2022, as a continuation of a prospective study in which all patients (197) were reviewed for 2 years after surgery (1, 6, 12, and 24 months). Preoperative demographic data, comorbidities, and pressure-flow studies were also recorded. Continence status and satisfaction rates were assessed using the International Consultation on Incontinence Questionnaire-short form (ICIQ-SF) and the Patient Global Impression of Improvement (PGI-I) respectively. The assessment in the 2022 retrospective review was performed via a telephone survey.

RESULTS

Mean follow-up time after surgery was 85.3 months (82.5-88.1). In 2022, complete continence was present in 75.4% of the patients. The presence of urinary urgency conditioned the ICIQ-SF score (10.9 vs 1.7 points, p < 0.01), with the ICIQ-SF = 0 in 84.5% of the patients with no associated urgency. Satisfaction assessed by the PGI-I was high, with 84.6% of the patients showing improvement. De novo urgency was present in 37,9% of the patients by 2022. Urinary tract infections were the most frequent complication (9.7%), with only 5 documented cases of mesh erosion.

CONCLUSIONS

Altis® SIS is a safe and effective device for SUI treatment, with satisfaction rates comparable with those of the conventional slings. Persistence or development of urinary urgency influences the results.
