The Potential of Non-ablative Erbium (YAG) Laser Treatment for Complications After Midurethral Sling Surgery: A Narrative Review

Midurethral sling (MUS) surgery, using tension-free vaginal tape and transobturator tape, has been widely adopted for the treatment of stress urinary incontinence (SUI). However, postoperative complications, including persistent urinary incontinence, mesh exposure, and pain, have become problematic, and surgical treatments for these complications face challenges, such as invasiveness, treatment-resistant cases, and recurrence. This review provides an overview of the current evidence regarding these complications and the potential of vaginal non-ablative erbium (YAG) laser (VEL) treatment as a minimally invasive option with low risk of complications. Studies have suggested the effectiveness of VEL treatment, performed using devices such as IncontiLase (SP Dynamis; Fotona d.o.o., Ljubljana, Slovenia), for persistent urinary incontinence after MUS surgery, pain following mesh removal, and asymptomatic mesh exposure. VEL treatment is expected to be a new treatment option for complications following MUS surgery; however, further large-scale comparative trials are required to verify its efficacy and safety and to establish criteria for its indications. Appropriate assessment of the indications and provision of sufficient information to patients is important when presenting VEL as a treatment option.

The Risk of Stress Urinary Incontinence After Hysterectomy for Uterine Fibroids

PURPOSE

We evaluated the relationship between previous hysterectomy for uterine fibroids and subsequent stress urinary incontinence (SUI).

METHODS

This study analyzed national health insurance data. The hysterectomy group (aged 40 to 59) comprised patients who underwent hysterectomy for uterine fibroids between January 1, 2011 and December 31, 2014, and the control group (aged 40 to 59) comprised patients who visited a medical facility for a checkup during the same time span. One-to-one propensity score matching was performed to balance confounders. SUI was defined as the need for SUI surgery accompanied by a diagnosis code for SUI.

RESULTS

After matching, 81,373 cases (hysterectomy group) and 81,373 controls (nonhysterectomy group) were enrolled. The mean follow-up period was 7.9 years for the cases and 7.8 years for the controls. The incidence of anti-incontinence surgery was slightly but significantly higher in the cases than in the controls (2.0% vs. 1.7%, P<0.001). Compared to the control group, abdominal hysterectomy significantly increased the likelihood of anti-incontinence surgery both before (hazard ratio [HR], 1.235; 95% confidence interval [CI], 1.116-1.365) and after adjusting for confounders (HR, 1.215; 95% CI, 1.097-1.347). In contrast, laparoscopic hysterectomy, laparoscopic hysterectomy with adnexal surgery, and abdominal hysterectomy with adnexal surgery were not associated with an increased rate of anti-incontinence surgery. The significant association between abdominal hysterectomy and an elevated rate of anti-incontinence surgery persisted even after stratifying patients by age group.

CONCLUSION

Prior abdominal hysterectomy without adnexal surgery was associated with an increased incidence of subsequent anti-urinary incontinence surgery.
