Laser versus sham for genitourinary syndrome of menopause: A randomised controlled trial

European Board and College of Obstetrics and Gynaecology (EBCOG) position statement on the use of laser vaginal devices for treatment of genitourinary syndrome of menopause, vaginal laxity, pelvic organ prolapse and stress urinary incontinence

One in three women will experience pelvic floor disorders in her lifetime and nearly 60 percent of postmenopausal women are affected by vaginal dryness. Conservative management is recommended as first line treatment for pelvic organ prolapse and stress urinary incontinence. Also, vaginal estrogens are often prescribed for symptomatic vaginal atrophy. Lasers have been used in cosmetic industry for connective tissue remodeling and repair of skin. Their use in the last decade for treating genitourinary symptoms of menopause, pelvic organ prolapse and stress urinary incontinence has gained popularity but there is lack of robust evidence to support its use in routine practice. The European Board and College of Obstetrics and Gynaecology calls for high quality evidence with patient related outcome measures before adopting to routine clinical practice.

Multifaceted Impact of CO2 Laser Therapy on Genitourinary Syndrome of Menopause, Vulvovaginal Atrophy and Sexual Function

Genitourinary syndrome of menopause (GSM) encompasses a range of distressing symptoms in the vulvovaginal and/or bladder-urethral regions related to menopause changes, negatively influencing woman's quality of life and sexual activity. Fractional micro-ablative CO2 laser therapy has shown the potential to reinstate the vaginal epithelium to a condition akin to the premenopausal state, thereby ameliorating the subjective symptoms associated with GSM. We conducted a prospective, pilot study in 73 sexually active postmenopausal women treated with CO2 laser for their GSM symptoms, while assessing Vaginal Health Index Score (VHIS) and sexual function through the Female Sexual Function Index (FSFI) Questionnaire. The laser treatment resulted in a decrease in VHIS and patient-reported vulvovaginal atrophy (VVA) symptoms, with a significantly lower prevalence of vaginal itching, dryness, and burning (p < 0.001), as well as dyspareunia (p = 0.002). The occurrence of urinary incontinence, urgency, and vaginal heaviness significantly reduced, with an improvement in the staging of cystocele, either to Stage 1 or complete resolution (p < 0.001). FSFI total and domain scores were significantly higher after the treatment, indicating better sexual function, with a post-treatment score median of 25 (p < 0.001). Therefore, using a three-cycle fractional CO2 laser was an effective choice for reducing urogenital discomfort related to GSM in postmenopausal women.

Should I stay for local hormone therapy or should I go for radiofrequency to treat vulvovaginal atrophy? A patient preference trial

OBJECTIVE

To compare patient satisfaction rate in postmenopausal women who chose dynamic quadripolar radiofrequency or topical estrogens as their preferred treatment for genitourinary syndrome of menopause.

METHODS

Patients were divided into two groups according to their preference: one was treated with estrogen therapy (ET) and the other with dynamic quadripolar radiofrequency treatment (RF). All patients included fulfilled a series of validated questionnaires, at baseline and at the 6-mo follow-up, in order to evaluate the discomfort degree associated with the presence of vulvovaginal atrophy and the impact of the reported symptoms on QoL and sexuality.

RESULTS

After propensity score matching, the proportion of women considering themselves satisfied with their genital health conditions was extremely small at study entry (5.2% of the RF group and 6.9% of the ET group), while at a 6-mo follow-up, it increased to 46.7% and 46.6%, respectively. No statistically significant between-group differences were found regarding mean numerical rating scale scores for dryness and dyspareunia at follow-up (5.6 ± 2.6 vs 5.3 ± 2.3, P = 0.5; and 2.9 ± 2.5 vs 3.0 ± 2.7, P = 0.46). At 6-mo follow-up, we observed no statistically significant differences between the two groups regarding the other items evaluated. RF treatment was overall well tolerated.

CONCLUSION

The use of quadripolar radiofrequency devices seems effective, but it is not associated with better clinical outcomes compared with topical hormone treatment, which is a substantially cheaper and more convenient treatment for genitourinary syndrome of menopause. Therefore, we suggest limiting the use of dynamic quadripolar radiofrequency selectively when topical estrogens are not effective, not tolerated, or contraindicated.

Regenerative Medicine in Urogynecology: Where We Are and Where We Want to Be

ABSTRACT

Pelvic floor disorders (PFDs) constitute a major public health issue given their negative effect on quality of life for millions of women worldwide and the associated economic burden. As the prevalence of PFDs continues to increase, novel therapeutic approaches for the effective treatment of these disorders are urgently needed. Regenerative medicine techniques, including cellular therapies, extracellular vesicles, secretomes, platelet-rich plasma, laser therapy, and bioinductive acellular biomaterial scaffolds, are emerging as viable clinical options to counteract urinary and fecal incontinence, as well as pelvic organ prolapse. This brief expert review explores the current state-of-science regarding application of these therapies for the treatment of PFDs. Although regenerative approaches have not been widely deployed in clinical care to date, these innovative techniques show a promising safety profile and potential to positively affect the quality of life of patients with PFDs. Furthermore, investigations focused on regeneration of the main constituents of the pelvic floor and lower urinary tract improve our understanding of the underlying pathophysiology of PFDs. Regenerative medicine techniques have a high potential not only to revolutionize treatment of PFDs but also to prevent these complex conditions.

Randomized trial: treatment of genitourinary syndrome of menopause using radiofrequency

OBJECTIVE

A randomized controlled study was conducted to evaluate the safety and efficacy of radiofrequency treatment in postmenopausal women not willing to use or presenting a contraindication for menopause hormone therapy (MHT) and suffering from genitourinary syndrome of menopause (GSM).

METHODS

A prospective randomized open study evaluated the effect of radiofrequency treatment versus a gel (control group) in postmenopausal women suffering from GSM. Patients were assessed at baseline and after 10-12 weeks of treatment for severity of vulvovaginal atrophy, dyspareunia, pH, vaginal smear maturation index, Vaginal Health Index and Female Sexual Function Index. The difference at baseline and after 10-12 weeks of treatment and the difference in improvement were tested between groups by a two-sample t-test and the Mann-Whitney test.

RESULTS

Due to the COVID-19 pandemic, we were only able to treat 48 patients (24 patients using radiofrequency and 24 patients using a gel). Globally, at the end of the study, there were no differences in changes of the measured outcomes between the group of women treated with radiofrequency and the control group.

CONCLUSION

Radiofrequency treatment was found to be safe, but was not superior to a gel, although the study lacked power. The study was registered at ClinicalTrials.gov (NCT03857893).

An empowerment model for managing menopause

Menopause eventually happens to all people with typically functioning ovaries, and almost one billion women worldwide are postmenopausal. Although the biology of typical menopause is ubiquitous, the experience varies substantially. Factors contributing to the experience include not only individual factors, such as the nature and severity of symptoms, but also psychological, social, and contextual considerations, many of which are modifiable. In this first paper in the Lancet Series on menopause, we argue for a new approach that goes beyond the treatment of specific symptoms, to encompass a broad model to support women transitioning this life stage, using the model of empowerment. WHO defines empowerment as an active process of gaining knowledge, confidence, and self-determination to self-manage health and make informed decisions about care. Rather than focusing on menopause as an endocrine deficiency, we propose an empowerment model that recognises factors modifying the experience, in which the patient is an expert in their own condition and the health-care worker supports the patient to become an equal and active partner in managing their own care.

Lower Urinary Tract Symptoms in Greek Women After Menopause: The LADY Study

INTRODUCTION AND HYPOTHESIS

The genitourinary syndrome of menopause (GSM), apart from symptoms related to vulvovaginal atrophy (VVA), also consists of lower urinary tract symptoms (LUTS). Based on the common embryological origin of the genital and lower urinary system, the presence of estrogen receptors, and the high prevalence of VVA and LUTS in the menopausal population, the two conditions can coexist. This study is aimed at investigating the prevalence and risk factors of LUTS in a sample of Greek peri- and postmenopausal women.

METHODS

Four hundred and fifty (450) women, aged 40-70 years, attending three outpatient gynecology clinics for routine examination, completed a structured interview and responded to a validated questionnaire (International Consultation on Incontinence Questionnaire Female Lower Urinary Tract Symptoms, ICIQ-FLUTS).

RESULTS

Urinary urgency or frequency affected 51.6% and dysuria 43.6% of the participants. Mild urgency or frequency was described by 25.6%, moderate by 14.4%, and severe by 11.6% of the women. Mild dysuria was reported by 26.26%, moderate by 5.8%, and severe by 11.6%. Age, weight, BMI, and number of pregnancies and abortions correlated with a higher ICIQ-FLUTS score. Women with moderate/severe symptoms of VVA, such as irritation, a burning sensation, and pruritus of the vulva or vagina, had a higher ICIQ-FLUTS score than women without such symptoms (beta coefficient 2.42, CI 1.204, 3.635, p < 0.001).

CONCLUSIONS

Lower urinary tract symptoms are very common among peri- and postmenopausal women and are linked to symptoms of VVA. Our data support the need for prompt evaluation of women transitioning to menopause, as these symptoms compromise the quality of life.

Fractional CO2 laser for genitourinary syndrome of menopause: evaluating the evidence

The fractionated CO2 laser has been marketed to women for a variety of gynecologic symptoms and conditions, including the genitourinary syndrome of menopause (GSM). The evidence has been limited, precluding conclusions regarding the efficacy and safety of the therapy. However, data from randomized, controlled trials evaluating this technology for GSM are now available. This Practice Pearl addresses the latest data concerning the use of the fractionated CO2 laser for the treatment of GSM.

Carbon dioxide laser therapy for the management of genitourinary syndrome of menopause: A meta‑analysis of randomized controlled trials

Genitourinary symptoms of menopause (GSM) affect ~50% of women after menopause. Recently, CO2 laser therapy has been used for managing GSM but without high quality evidence. The present review assessed the effectiveness of CO2 laser therapy in the management of GSM. PubMed, Embase, Web of Science, CENTRAL and Scopus databases were searched for randomized controlled trials (RCTs), published up to June 30, 2023, comparing CO2 laser and sham laser treatments for GSM management. The outcomes of interest included Female Sexual Function Index (FSFI), Vaginal Health Index (VHI) and visual analog scale (VAS) for dyspareunia, dryness, burning, itching and dysuria. A total of seven RCTs were included in the review and meta-analysis, with 6/7 studies using three sessions of laser therapy, 4-8 weeks apart. Meta-analysis demonstrated no statistically significant difference in FSFI [mean difference (MD), -1.48; 95% CI, -5.85, 2.89; I2=45%] and VHI scores (MD, -0.18; 95% CI, -1.66, 1.31; I2 =72%) between laser and control groups. Meta-analysis also demonstrated no statistically significant difference in VAS scores for dyspareunia (MD, -1.63; 95% CI; -4.06, 0.80; I2=91%), dryness (MD, -1.30; 95% CI, -3.14, 0.53; I2=75%), burning (MD, -0.76; 95% CI, -2.03; 0.51 I2=56%), itching (MD, -0.28; 95% CI, -0.95, 0.38; I2=0%) and dysuria (MD, 0.15; 95% CI, -0.37, 0.67; I2=23%) between the groups. The included RCTs had low risk of bias. In conclusion, meta-analyses of high-quality sham-controlled RCTs indicated that CO2 may not have any beneficial effect on GSM. Limited data and high heterogeneity in meta-analyses in this area of research are important limitations that need to be addressed by future RCTs.

CO2 Laser versus Sham Control for the Management of Genitourinary Syndrome of Menopause: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

In the context of the menopausal transition, genitourinary syndrome of menopause (GSM) refers to a range of genitourinary symptoms, from vaginal dryness to dysuria and urinary urgency. While hormonal treatments are standard, their associated side effects have driven the exploration of alternatives like vaginal CO2 laser. We aimed to evaluate the randomized controlled trials (RCTs) comparing vaginal CO2 laser treatment for GSM to sham controls. This systematic review sourced four electronic databases until June 2023. The analysis incorporated seven RCTs with 407 women. The CO2 laser and sham control were comparable for most parameters, including the female sexual function index (FSFI) and visual analogue scale (VAS) for dyspareunia, vaginal health index, pH, and patient satisfaction. However, the CO2 laser group showed significant improvement in the vaginal assessment scale for GSM symptoms. Sensitivity analyses revealed that parameters like FSFI showed significant differences in favor of CO2 laser group upon the exclusion of specific studies. In conclusion, vaginal CO2 laser therapy emerges as a promising alternative for GSM management, especially for most bothersome GSM symptoms; however, the need for further well-designed RCTs remains to validate its broad safety and efficacy.

Vaginal Laser Treatment for the Genitourinary Syndrome of Menopause in Breast Cancer Survivors: A Narrative Review

Vulvovaginal atrophy (VVA) is a chronic condition resulting from reduced estrogen levels during menopause. The North American Menopause Society and the International Society for the Study of Women's Sexual Health suggested the term "genitourinary syndrome of menopause" (GSM) to indicate the broader aspects of VVA. Breast cancer treatments, such as chemotherapy and endocrine therapy, can induce early and abrupt menopausal symptoms, including GSM, which negatively affects sexual function and the quality of life of the survivors. Vaginal laser therapy has emerged as a safe and effective option for the management of GSM in breast cancer survivors (BCSs). Two main types of lasers, the non-ablative erbium:YAG laser and fractional microablative CO2 vaginal laser, have been evaluated for GSM treatment. While there are few randomized controlled trials (RCTs) on the subject of BCSs, a wealth of prospective and retrospective studies have highlighted the beneficial effects of vaginal laser therapy on the symptoms of VVA, vaginal health, sexual function, and overall quality of life. More comprehensive research is essential to confirm its enduring effectiveness and safety, with a focus on conducting standardized and meticulously controlled investigations. This study is a narrative review that summarizes clinical trials ranging from the earliest to the most recent ones on laser treatment for GSM in BCSs.

Efficacy and safety of carbon dioxide laser therapy compared with sham for genitourinary syndrome of menopause management: a meta-analysis of randomized clinical trials

IMPORTANCE

Data on whether the carbon dioxide (CO 2 ) laser is useful for treatment of genitourinary syndrome of menopause (GSM) are inconsistent.

OBJECTIVE

This meta-analysis evaluated the benefits and safety of CO 2 laser compared with sham treatment of GSM.

EVIDENCE REVIEW

A relevant literature search of Europe PMC, MEDLINE, Scopus, and ClinicalTrials.gov databases using specific keywords was conducted. The results of continuous variables were pooled into the standardized mean difference (SMD), whereas dichotomous variables were pooled into odds ratio with 95% confidence intervals (95% CI) using random-effects models. A funnel plot was used to assess for the presence of publication bias.

FINDINGS

A total of six randomized clinical trials were included. Pooled analysis revealed that CO 2 laser therapy was associated with a higher reduction in the Vaginal Assessment Scale (SMD, -0.81 [95% CI, -1.59 to -0.04]; P = 0.04; I2 = 88%) and Urinary Distress Inventory short form (SMD, -0.45 [95% CI, -0.84 to -0.06]; P = 0.02; I2 = 0%), and greater patient satisfaction rate (odds ratio, 5.46 [95% CI, 2.23 to 13.37]; P = 0.0002; I2 = 0%) when compared with sham-only treatment. Meanwhile, the Female Sexual Function Index, Vaginal Health Index, and Patient Global Impression Improvement did not differ significantly between groups. Adverse events were only mild with no serious adverse events reported.

CONCLUSIONS AND RELEVANCE

CO 2 laser therapy may improve the overall treatment of GSM with a relatively good safety profile. However, further randomized clinical trials with larger sample sizes are still needed to confirm the results of this study.

Genitourinary Syndrome of Menopause in Breast Cancer Survivors: Current Perspectives on the Role of Laser Therapy

Genitourinary syndrome of menopause (GSM) is a frequent consequence of iatrogenic menopause or anti-estrogenic adjuvant therapies in breast cancer survivors (BCSs). GSM may profoundly affect sexual health and quality of life, and a multidimensional unique model of care is needed to address the burden of this chronic heterogeneous condition. Severe symptoms may be insufficiently managed with non-hormonal traditional treatments, such as moisturizers and lubricants, recommended as the first-line approach by current guidelines, because concerns exist around the use of vaginal estrogens, particularly in women on aromatase inhibitors (AIs). Vaginal laser therapy has emerged as a promising alternative in women with GSM who are not suitable or do not respond to hormonal management, or are not willing to use pharmacological strategies. We aim to systematically review current evidence about vaginal laser efficacy and safety in BCSs and to highlight gaps in the literature. We analyzed results from 20 studies, including over 700 BCSs treated with either CO2 or erbium laser, with quite heterogeneous primary outcomes and duration of follow up (4 weeks-24 months). Although evidence for laser efficacy in BCSs comes mostly from single-arm prospective studies, with only one randomized double-blind sham-controlled trial for CO2 laser and one randomized comparative trial of erbium laser and hyaluronic acid, available data are reassuring in the short term and indicate effectiveness of both CO2 and erbium lasers on the most common GSM symptoms. However, further studies are mandatory to establish long-term efficacy and safety in menopausal women, including BCSs.

Vaginal laser therapy for GSM/VVA: where we stand now - a review by the EUGA Working Group on Laser

Vulvovaginal atrophy (VVA) is a chronic progressive condition that involves the genital and lower urinary tracts, related to the decrease of serum estrogenic levels when menopause occurs. The definition of genitourinary syndrome of menopause (GSM) is a medically more accurate, all-encompassing and publicly acceptable term than VVA. Due to the chronic progressive trend of GSM, symptoms tend to reappear after the cessation of therapy, and frequently long-term treatment is required. First-line therapies include vulvar and vaginal lubricant or moisturizers, and, in the case of failure, low-dose vaginal estrogens are the preferred pharmacological therapy. Populations of patients, such as breast cancer (BC) survivors, are affected by iatrogenic GSM symptoms with concerns about the use of hormonal therapies. The non-ablative erbium:YAG laser and the fractional microablative CO2 vaginal laser are the two main lasers evaluated for GSM treatment. The aim of this comprehensive review is to report the efficacy and safety of Er:YAG and CO2 vaginal lasers for GSM treatment. Vaginal laser therapy has been demonstrated to be effective in restoring vaginal health, improving VVA symptoms and sexual function. The data suggest that both Er:YAG and CO2 vaginal lasers are safe energy-based therapeutic options for management of VVA and/or GSM symptoms in postmenopausal women and BC survivors.

The efficacy of CO2 laser in the treatment of genitourinary syndrome of menopause: a systematic review and meta-analysis of randomized controlled trials

CO₂ laser has been proposed as a treatment strategy for genitourinary syndrome of menopause (GSM). In order to assess its efficacy for treating GSM, we conducted a systematic review and meta-analysis. To identify the current state of randomized controlled trials on CO₂ laser therapy for GSM, a literature review was conducted. We systematically searched the following databases: PUBMED, EMBASE and the Cochrane Controlled Trials Register. In addition, a review of the references in the retrieved studies was carried out. Of 562 identified studies, 9 were eligible and were included in our analysis, involving 523 patients in total. Based on our analysis, CO₂ laser has no statistical difference compared with estrogen in VHI (p = 0.87), FSFI total score (p = 0.19), FSFI-Arousal (p = 0.11), FSFI-Desire (p = 0.72), FSFI-Orgasm (p = 0.45) and FSFI-Satisfaction (p = 0.08). The meta-analysis also showed that CO₂ laser significantly improved FSFI-Lubrication scores compared with estrogen therapy (p = 0.0004). Furthermore, compared with the sham group, CO₂ laser group had statistically improved VHI scores (p = 0.003) and FSFI scores (p < 0.00001). CO₂ laser therapy may be an effective alternative to estrogen therapy for GSM both in cases where estrogen is not applicable because of comorbidities and in cases in which women do not desire to take estrogen.

The effect of CO2 laser therapy on vaginal microcirculatory parameters in an animal model for genitourinary syndrome of menopause

BACKGROUND

Vaginal laser therapy for the treatment of genitourinary syndrome of menopause (GSM) has been introduced to the market with limited (pre)clinical and experimental evidence supporting its efficacy. It is suggested that vaginal laser therapy increases epithelial thickness and improves vascularization, but the underlying biological working mechanism has not been substantiated yet.

OBJECTIVE

To evaluate the effects of CO₂ laser therapy on vaginal atrophy using noninvasive incident dark field (IDF) imaging in a large animal model for GSM.

DESIGN, SETTING, AND PARTICIPANTS

An animal study was conducted between 2018 and 2019 and included 25 Dohne Merino ewes, of which 20 underwent bilateral ovariectomy (OVX) to induce iatrogenic menopause, and 5 did not. The total study duration was 10 months.

INTERVENTIONS

Five months after OVX, ovariectomized ewes received monthly applications of CO₂ laser (n = 7), vaginal estrogen (n = 7), or no treatment (n = 6) for 3 months. IDF imaging was performed monthly in all animals.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

The primary outcome was the proportion of image sequences containing capillary loops (angioarchitecture). Secondary outcomes included focal depth (epithelial thickness), and quantitative measures of vessel density and perfusion. Treatment effects were evaluated using ANCOVA and binary logistic regression.

RESULTS AND LIMITATIONS

Compared to OVX-only, ewes treated with estrogen demonstrated a higher capillary loops proportion (4% vs. 75%, p < 0.01), and higher focal depth (60 (IQR 60-80) vs. 80 (IQR 80-80) p < 0.05). CO₂ laser therapy did not change microcirculatory parameters. As the ewes' vaginal epithelium is thinner than that of humans, it may demand different laser settings.

CONCLUSIONS

In a large animal model for GSM, CO₂ laser therapy does not affect microcirculatory outcomes related to GSM, whereas vaginal estrogen treatment does. Until more homogeneous and objective evidence about its efficacy is available, CO₂ laser therapy should not be adopted into widespread practice for treating GSM.
