A 12-week treatment with fractional CO2 laser for vulvovaginal atrophy: a pilot study

The effects of a real-time temperature monitoring non-ablative monopolar radiofrequency technology on vulvovaginal atrophy symptoms in postmenopausal Chinese women

BACKGROUND

Vulvovaginal atrophy (VVA) includes a wide range of conditions affecting the reproductive and urinary systems, often requiring careful evaluation and management for optimal health.

AIMS

This study aims to evaluate the symptom management effects of a real time temperature-monitored non-ablative RF device for the treatment of postmenopausal Chinese women with VVA symptoms.

METHODS

This pilot study involved 24 postmenopausal Chinese women with one or more VVA symptoms, who wished to remain sexually active. VHIS, VAS, and FSFI were used to track and evaluate various aspects of the patient's condition. Analyses were conducted at the end of the study to verify the statistical significance of the treatment's results.

RESULTS

All patients reported substantial, statistically significant, improvements on every VVA symptom tracked. Approximately 80% of the patients reported total symptom reversal at 12-week post-treatment follow-up.

CONCLUSION

This pilot study demonstrated that non-ablative, monopolar RF technology equipped with real time temperature monitoring is feasible and safe in the treatment of postmenopausal women with VVA symptoms, and efficacious at up to 12 weeks post-treatment.

Comparison of promestriene with vaginal fractional CO2 laser and radiofrequency treatments of genitourinary syndrome of menopause

OBJECTIVE

To compare the effects of fractional CO2 laser and microablative fractional radiofrequency treatment with promestriene topical estrogen on sexual function and genitourinary syndrome of menopause symptoms.

METHODS

This was a prospective randomized open-label clinical trial conducted with 62 postmenopausal women assigned to three intervention groups: a) topical promestriene for 90 days (n = 17); b) fractional CO2 laser treatment (n = 24); and c) microablative fractional radiofrequency treatment (n = 21). Each of the latter two groups underwent three treatment sessions at 4-week intervals. At baseline and at the end of the study, all participants had a gynecological examination that included vaginal pH measurement, and the completion of the Vaginal Symptom Score, the Vaginal Health Index, and the Female Sexual Function Index. For the energy treatment groups, adverse effects were evaluated after each session. Group homogeneity was assessed at baseline, and results were evaluated over time (from baseline to the end of treatment) and between groups over time.

RESULTS

All baseline parameters were similar among studied groups. At the end of the study, all 3 treatments had produced similar effects: a reduction of vaginal pH, and an improvement of vulvovaginal symptoms (Vaginal Symptom Score and Vaginal Health Index scores) as well as sexual function (higher total Female Sexual Function Index scores, and in the desire, arousal, lubrication and pain domain scores), with no differences observed between groups. Side-effects were slight for both energy treatment groups, mainly represented by vaginal discharge.

CONCLUSION

The present study suggests that the two energy treatments were efficient along with promestriene at improving postmenopausal genitourinary and sexuality symptoms. Clinical trial identification numberNCT04717245.

The 100 top-cited articles in menopausal syndrome: a bibliometric analysis

BACKGROUND

Significant scientific research has been conducted concerning menopausal syndrome(MPS), yet few bibliometric analyses have been performed. Our aim was to recognise the 100 most highly cited published articles on MPS and to analytically evaluate their key features.

METHODS

To identify the 100 most frequently cited articles, a search was conducted on Web of Science using the term 'menopausal syndrome'. Articles that matched the predetermined criteria were scrutinised to obtain the following data: citation ranking, year of publication, publishing journal, journal impact factor, country of origin, academic institution, authors, study type, and keywords.

RESULTS

The publication period is from January 1, 2000, to August 31, 2022. The maximum number of citations was 406 and in 2012. The median citations per year was 39.70. Most of the articles focused on treatment and complications. These articles were published in 36 different journals, with the Journal of MENOPAUSE having published the greatest number (14%). Forty-eight articles (48%) were from the United States, with the University of Pittsburgh being the leading institute (9%). Joann E. Manson was the most frequent first author (n = 6). Observational studies were the most frequently conducted research type (n = 53), followed by experimental studies (n = 33). Keyword analysis identified classic research topics, including genitourinary syndrome of menopause, bone mineral density (BMD), and anti-mullerian hormone (AMH) loci.

CONCLUSION

Using bibliometrics, we conducted an analysis to identify the inadequacies, traditional focal points, and potential prospects in the study of MPS across current scientific areas. Treatment and complications are at the core of MPS research, whereas prediction and biomarkers have less literature of high quality. There is a necessity for innovative analytical metrics to measure the real effect of these papers with a high level of citation on clinical application.

Combined clinical and radiological remission of rectovaginal fistulas using fractional CO2 vaginal laser: a case series and medium-term follow-up

INTRODUCTION

Despite the advances in surgical and clinical approaches, there is no consensus regarding the best line of treatment from rectovaginal fistula (RVF). Faced with a challenging scenario in the approach of RVF, the fractional CO2 laser receives attention as a possible form of treatment.

OBJECTIVES

A single-center, prospective, open-label study evaluating the effectiveness and safety of laser therapy for RVF treatment.

SUBJECTS AND METHODS

The total of 15 patients was recruited at the Juiz de Fora University Hospital between August 2018 and July 2022. Inclusion criteria were presence of clinically suspects RVF of any etiology confirmed by pelvic magnetic resonance image (MRI) and gynecological examination. Five fractional CO2 laser sessions with monthly interval followed by complete evaluation through clinical examination and pelvic MRI were performed for all patients after the completion of treatment. Analysis of sexual function before and after the treatment was performed using Female Sexual Quotient (FSQ).

RESULTS

The evaluation through physical examination showed no persistent inflammatory signs in the vagina for all patients. Additionally, 10 of out 15 (67.7%) patients achieved clinical remission of RVF symptoms, while 33.3% patients reported significant improvement. Of note, five patients who did not have previous sexual activity returned to regular sexual activity while seven patients who have baseline sexual activity had improvement in their sexual function as assessed by the FSQ. Three out of four ostomized patients had their ostomy reversed and remained without complains. All six patients with RVF secondary to Crohn's disease reported a marked improvement in symptoms and sexual function. In seven (47%) patients radiological remission was confirmed by pelvic MRI.

CONCLUSION

CO2 fractional laser can be considered a promising and safe therapeutic alternative for the management of RVF.

Long-term clinical and histological safety and efficacy of the CO2 laser for treatment of genitourinary syndrome of menopause: an original study

OBJECTIVE

This study aimed to evaluate histological modifications of the vaginal mucosa after repeated microablative fractional CO2 laser treatments. As secondary objectives we evaluated the clinical effects associated with repeated microablative fractional CO2 laser treatments using validated questionnaires.

METHODS

A prospective intervention study was performed in the Division of Gynecology and Obstetrics, Urogynecology Unit, IRCCS San Raffaele Scientific Institute with 15 postmenopausal women complaining of genitourinary syndrome of menopause symptoms. The cohort of patients was submitted to at least two previous laser treatment cycles in the past years. The Vaginal Health Index (VHI), visual analog scale (VAS), Female Sexual Function Index (FSFI), Urinary Distress Inventory-6 (UDI-6), International Consultation on Incontinence Questionnaire - Urinary Incontinence (ICIQ-UI) and 5-point Likert scale were used. Moreover, histological examinations were carried out on all samples.

RESULTS

At 4 weeks after the last treatment, the VHI score and all FSFI items were significantly increased compared with baseline. We observed a statistically significant decrease in both frequency and severity for all urinary symptoms after the follow-up. We observed a statistically significant increase in the number of epithelial cell layers with a consequent increase in epithelial thickness, in the number of glycogen-filled cells and in the number of papillae after the laser treatment. No signs of fibrosis were observed as neovascularization was observed in each woman.

CONCLUSIONS

This is the first study demonstrating the histological persistency of efficacy in repeated annually laser treatment cycles, with tissue changes always leading to regenerative results without any sign of fibrosis.

Efficacy of Fractional Laser on Steroid Receptors in GSM Patients

BACKGROUND

To compare the efficacy of CO2 fractional laser with that of topical estriol for treating genitourinary syndrome of menopause and to investigate the relationship between epithelial thickness and vaginal atrophy.

METHODS

Twenty-five menopausal women were randomized to receive either laser or estrogen treatment. Vaginal biopsies before and after treatment were compared to assess the amount and distribution of estrogen and progesterone receptors.

RESULTS

Estrogen receptor levels were statistically similar between groups before and after treatment. Although there was no change over time in the estrogen group, an increase in receptor levels was confirmed in the laser group. Changes in estrogen receptor levels showed no association with treatment. Progesterone receptor levels were statistically similar between groups throughout treatment. There was no change over time in both groups. These changes displayed no association with the type of treatment. There was no significant correlation between epithelium thickness and estrogen or progesterone receptor levels.

CONCLUSIONS

Estrogen and progesterone receptor levels increased and were maintained, respectively, in the vaginal epithelium in both groups. There was no significant relationship between epithelium thickness and receptor density. Laser therapy had similar outcomes to the gold standard without involving the disadvantages of hormone therapy.

Clinical and laboratory results in vaginal wall restoration using a fractional-pixel-CO2 laser: histological findings and changes in the Ki67 protein and telomere length

Thermal deposition of laser energy in the vaginal epithelium in genitourinary syndrome of menopause (GSM) results in clinical and biological effects, but many cellular and molecular changes indicating cell proliferation or senescence inhibition are unknown. The aim of this study is to evaluate the clinical efficacy of the fractional-pixel-CO2 laser in the possible improvement of GMS signs and symptoms that can be correlated with histological changes or with cellular or molecular indicators of restoration. A detailed prospective study was designed to assess 17 women diagnosed with GSM who were treated intravaginally with two laser sessions. Seven non-treated women diagnosed with GSM were used as controls. Three validated outcome questionnaires for assessment of quality of sexual life and urinary incontinence were performed. Vaginal biopsies were collected before the first laser treatment and 4 months following the second session. Histological status, elastin, collagen, and hyaluronic acid content of the biopsies were also evaluated. Cell proliferation was assessed by Ki67 staining. Telomere length (TL) was measured by qPCR. The results show an improvement of the clinical symptoms of GSM (p < 0.05), vaginal epithelium recovery and enhancement of collagen (p < 0.05), elastic fibers (p < 0.005), and hyaluronic acid (p < 0.0005) content in the lamina propria after fractional-pixel-CO2 laser treatment. The laser treatment induced a significant rise on the TL of vaginal epithelial cells (VECs), and a positive correlation was found between the improvements of the collagen and hyaluronic acid content and TL changes (r = 0.82, p < 0.05; r = 0.38, p < 0.05). The percentage of proliferative Ki67-positive VECs was increased in patients whose vaginal TL lengthened after laser treatment (p < 0.05). In conclusion, the results indicate that laser treatment may induce restoration of the vaginal epithelium which is associated to increased TL and proliferation in the VECs. Performing a TL assay could be a suitable tool to evaluate the efficacy of vaginal laser treatment.

Nonestrogen Therapies for Treatment of Genitourinary Syndrome of Menopause: A Systematic Review

OBJECTIVE

To systematically review the literature and provide clinical practice guidelines regarding various nonestrogen therapies for treatment of genitourinary syndrome of menopause (GSM).

DATA SOURCES

MEDLINE, EMBASE, ClinicalTrials.gov , and Cochrane databases were searched from inception to July 2021. We included comparative and noncomparative studies. Interventions and comparators were limited to seven products that are commercially available and currently in use (vaginal dehydroepiandrosterone [DHEA], ospemifene, laser or energy-based therapies, polycarbophil-based vaginal moisturizer, Tibolone, vaginal hyaluronic acid, testosterone). Topical estrogen, placebo, other nonestrogen products, as well as no treatment were considered as comparators.

METHODS OF STUDY SELECTION

We double-screened 9,131 abstracts and identified 136 studies that met our criteria. Studies were assessed for quality and strength of evidence by the systematic review group.

TABULATION, INTEGRATION, AND RESULTS

Information regarding the participants, details on the intervention and comparator and outcomes were extracted from the eligible studies. Alternative therapies were similar or superior to estrogen or placebo with minimal increase in adverse events. Dose response was noted with vaginal DHEA and testosterone. Vaginal DHEA, ospemifene, erbium and fractional carbon dioxide (CO 2 ) laser, polycarbophil-based vaginal moisturizer, tibolone, hyaluronic acid, and testosterone all improved subjective and objective signs of atrophy. Vaginal DHEA, ospemifene, tibolone, fractional CO 2 laser, polycarbophil-based vaginal moisturizer, and testosterone improved sexual function.

CONCLUSION

Most nonestrogen therapies are effective treatments for the various symptoms of GSM. There are insufficient data to compare nonestrogen options to each other.

Urologic view in the management of genitourinary syndrome of menopause

Genitourinary syndrome of menopause (GSM) has a variety of effects on the urinary system and is an important consideration in the care provided to perimenopausal and postmenopausal patients when addressing urinary pathology. Here we discuss the common pathologies of the urinary system related to GSM including lower urinary tract symptoms and recurrent urinary tract infections. Female sexual dysfunction is not to be excluded as a critical part of a urologist's management of GSM but will be discussed elsewhere in this issue.

Standardized Procedures for Patients with Dysplasia and Other Diseases of the Cervix, Vulva, and Vagina at a Certified Dysplasia Unit Prior to the Introduction of the Organized Cervical Cancer Screening Program

Introduction Gynecologic dysplasia units and dysplasia consultations are obliged to offer diagnosis and treatment in accordance with the guidelines. The organization of the consultation process, management of patient appointments, diagnosis, and treatment algorithms are heterogeneous. The legislation arising from the new Federal Joint Committee decision, dated 22 November 2018, concerning the organized cervical cancer screening program has been in force since 1 January 2020. In this article we provide an overview of the existing structures and interdisciplinary cooperation of specialized dysplasia units incorporated in certified gynecologic cancer center. Materials and Methods We carried out a retrospective database search of data collected prospectively from 1 July 2014 to 31 December 2019 at the dysplasia unit at the Department of Gynecology and Obstetrics, Erlangen University Hospital, which was the first dysplasia unit to be certified in 2014. Results A total of 5594 patients presented at the unit, and 16061 colposcopic, vulvoscopic, and anoscopic examinations were performed. Approximately 4100 examinations of the cervix, vagina, vulva, and anus are carried out each year, 1600 of these were exclusively cervix colposcopies. A total of 12197 cytology results were assessed, as well as 4850 histology results, and 8193 high-risk HPV tests. The quality indicators required by the dysplasia unit for annual recertification were met each year. Conclusion Certified dysplasia units and consultations form the central component in the algorithm for further investigating abnormal screening results; but they are also the first point of contact for a large number of patients with acute or chronic complaints in the genital region.

The 50 most cited articles and science mapping analysis of vaginal tightening

INTRODUCTION AND HYPOTHESIS

The study was aimed at exploring the 50 most cited articles related to vaginal tightening.

METHODS

The papers were searched through the Thomson Reuters Web of Science on 30 July 2022, and were ranked by the total number of citations. The included articles were analyzed for author, journal, country, number of citations, keywords, subject matter, and level of evidence. The search output was also imported into VOSviewer.

RESULTS

The 50 most cited articles were cited a combined total of 2,558 times. The papers were published between 1990 and 2020, of which 86% were published between 2010 and 2020. They included 38 original articles, 8 reviews, 3 editorial articles, and 1 letter. Most articles were published in gynecology-related journals (n=30, 60%). The articles covered a wide range of topics, the most common being laser/radiofrequency treatment, vaginal tightening procedures, and urinary incontinence. The majority presented findings supported by level IV or V evidence. Through co-occurrence analysis, high-frequency words and countries were displayed well.

CONCLUSIONS

The study shed light on frequently read articles and influential topics about vaginal tightening. The highly cited literature mainly focused on laser or radiofrequency treatments and gynecologists currently dominate the highly cited literature on vaginal tightening. The articles related to surgical treatments are low in number and evidence level so far. The co-occurrence analysis reveals the hot research content and active countries in the field. In general, the study provides useful evidence for future research and educational materials.

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.

Sexual function after energy-based treatments of women with urinary incontinence. A systematic review and meta-analysis

INTRODUCTION AND HYPOTHESIS

Urinary incontinence (UI) affects approximately 50% of adult women worldwide and is associated with declining sexual function (SF). Energy-based devices emerged as a minimally invasive alternative treatment. Nevertheless, their effect on sexuality is uncertain. We hypothesize that the UI energy treatment can lead to sexual function improvement.

METHODS

A search was performed in PubMed, Cochrane Library, Web of Science, Embase, and Scopus for randomized clinical trials (RCTs) and nonrandomized studies of intervention, which treated incontinent women using energy, with UI and sexual function (SF) as outcomes. Severe comorbidities, pelvic organ prolapse (POP)> grade 2, and use of medication to treat UI or that affects SF were excluded. Quality assessment and meta-analysis were performed.

RESULTS

From 322 articles, 11 RCTs were included for qualitative analysis. UI symptoms improved in all studies. Regarding SF, RCT with premenopausal women showed improvement in SF in the Er:Yag group (Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire-12 and Female Sexual Function Index). A prospective study showed improvement in SF independent of the grade of SUI. RF showed benefits for SF but was not superior to pelvic floor muscle training. One nonrandomized study of intervention with a High-Intensity Focused Electromagnetic Field showed significant improvement of SF in the Golombok Rust Inventory of Sexual Satisfaction total score, a decline in pain and dissatisfaction domains. Meta-analysis with 4 RCTs and 2 nonrandomized studies found no difference between groups (0.26 (95% CI -0.67 to 1.20, and -0.74 (95% CI -3.78 to 2.30) respectively).

CONCLUSIONS

This meta-analysis did not confirm that energy equipment improved the SF of women with UI.

Fractional CO2 Laser Treatment Is Safe and Effective for the Management of Genitourinary Syndrome of Menopause in Korean Women

This study evaluates the efficacy and safety of fractional CO₂ lasers for treating genitourinary syndrome of menopause (GSM) in Korean women. The patients received three laser applications at an interval of 4 weeks each. The severity of GSM symptoms was assessed using a visual analog scale (VAS) at baseline and at every visit. The objective scale was measured using the vaginal health index score (VHIS) and Vaginal Maturation Index (VMI) after completion of the laser procedure. During each procedure, the patients' pain in the VAS score was recorded. In the last visit, patients evaluated their satisfaction with the laser therapy using a 5-point Likert scale. Thirty women completed all the study protocols. After two sessions of laser therapy, some GSM symptoms (vaginal dryness and urgency) and VHIS improved significantly. After completion of the treatment, all GSM symptoms improved (p < 0.05), and the VHIS further increased significantly (VHIS at baseline, 8.86 ± 3.2 vs. V3, 16.83 ± 3.15, p < 0.001). The average satisfaction was 4.3. This study shows that fractional CO₂ laser treatment is effective and safe for Korean women with GSM. Further studies are needed to confirm these results and assess the long-term effects of laser therapy.

Randomized clinical trial with fractional CO2 laser and Clobetasol in the treatment of Vulvar Lichen Sclerosus: a clinic study of feasibility

OBJECTIVES

The main objective of the study was to describe and compare the feasibility of using fractional CO₂ laser to the usual treatment with Clobetasol. Randomized clinical trials brought together 20 women from a Brazilian university hospital, 9 of them were submitted to Clobetasol treatment and 11 to laser therapy. Sociodemographic data were obtained and quality of life parameters, vulvar anatomy, self-perception and histopathological analysis of vulvar biopsies were evaluated. Evaluations were made before the beginning of the treatment, during its implementation, right after its completion (3 months), and 12 months after. The SPSS 14.0 software was used, obtaining descriptive measurements. The level of significance adopted was 5%.

RESULTS

The clinical/anatomical characteristics of the vulva did not differ between the treatment groups, as much before as after its performance. There was no statistically significant difference between the treatments performed regarding the impact on the life quality of the patients. A higher satisfaction degree with the treatment was obtained with the patients in the Laser group in the third month of evaluation. Laser therapy also revealed higher occurrence of telangiectasia after treatment completion. Fractional CO2 laser has proven to be well accepted and is a promising therapeutic option. Registration number and name of trial registry The institutional review board status was approved by the Research Ethics Committee of HU/ UFJF under advisory number 2881073 and registered in the Brazilian Clinical Trials, with consent under registration RBR-4p9s5y.

Fractional carbon dioxide vaginal laser treatment of stress urinary incontinence: Remodeling of vaginal tissues and improving pelvic floor structures

OBJECTIVE

To demonstrate remodeling of vaginal biomechanical and physiological properties using vaginal fractional carbon dioxide (CO₂ ) laser treatment of stress urinary incontinence (SUI).

MATERIALS AND METHODS

The study cohort included 26 patients with SUI between October 2019 and November 2020. Patients were treated with two sessions of FemTouch vaginal fractional CO₂ laser with a one-month interval. Three subjective assessments were administered to all patients: female sexual function index (FSFI), vaginal health index score (VHIS), and international consultation on incontinence questionnaire-short form (ICIQ-SF). Vaginal tissue biopsies were taken from 6 patients before treatment and one-month after the final treatment. Vaginal tactile imaging (VTI) measurements, ultrasonography, and magnetic resonance imaging (MRI) scans were performed before treatment and 10-12-months after treatment in 10, 9, and 6 patients, respectively.

RESULTS

The average age of the cohort was 39.5 ± 12.0 years. The overall scores for FSFI, VHIS, and ICIQ-SF significantly improved in patients after each treatment sessions as compared with baseline scores. VTI showed significantly increased pressure resistance of both the anterior and posterior vaginal walls after treatment. Ultrasonography showed significant decreases in bladder neck mobility and urethrovesical angle during the Valsalva maneuver after treatment. MRI scans showed significant decreases in the length of the vaginal anterior wall after treatment. Histological examination confirmed that the laser treatment led to a thicker stratified squamous epithelium layer as compared to the baseline.

CONCLUSIONS

Our results demonstrated that vaginal fractional CO₂ laser treatment can restore vaginal biomechanical and physiological properties by increasing vaginal tightening and improving pelvic floor structures.

Safety and efficacy of fractional CO2 laser treatment to the vestibule: a randomized, double-blind, sham-controlled, prospective 3-site clinical study in women with vestibular pain

BACKGROUND

Data are limited regarding fractional CO2 laser as a nonhormonal treatment for vestibular pain.

AIM

We sought to perform what is, to our knowledge, the first multisite prospective randomized, double-blind, sham-controlled clinical trial to assess the safety and efficacy of fractional CO2 laser treatment to the vestibule in women with vestibular pain.

METHODS

Subjects (n = 70) meeting inclusion/exclusion criteria at each of 3 sites were randomized 2:1 to active or sham (zero energy) fractional CO2 laser treatment using the vestibular probe (SmartXide2 V2LR - MonaLisa Touch, DEKA, Florence, Italy). Subjects in each treatment arm received 3 treatments 4 weeks apart. At the initial follow-up (week 12), subjects were unblinded and those initially assigned to sham started active treatment.

OUTCOMES

Outcome measures included changes from baseline in sexual activity diaries and scores for the Vulvoscopic Genital Tissue Appearance Scale (VGTA), vestibular cotton-tipped swab testing, McGill Pain Questionnaire, Female Sexual Function Index (FSFI), Female Sexual Distress Scale-Revised (FSDS-R), and the O'Leary-Sant voiding and pain indices, the Interstitial Cystitis Symptom Index (ICSI) and Interstitial Cystitis Problem Index (ICPI).

RESULTS

After active treatment, VGTA scores significantly improved in 5 parameters. Pain associated with cotton-tipped swab testing was significantly reduced at weeks 4 through 16 (mean change from baseline -0.64 [95% CI, -0.79 to -0.50] and -1.31 [95% CI, -1.46 to -1.16], respectively). FSFI pain domain scores improved significantly at weeks 12 and 16 (mean change from baseline 0.925 [95% CI, 0.10-1.75] and 1.22 [95% CI, 0.40-2.05], respectively). FSFI total scores increased significantly at weeks 12 and 16 (mean change from baseline 6.24 [95% CI, 2.64-9.85] and 4.96 [95% CI, 1.36-8.57], respectively). FSDS-R scores decreased significantly at weeks 12 and 16 (mean change from baseline -5.84 [95% CI, -8.80 to -2.87] and -9.15 [95% CI, -12.11 to -6.18], respectively). ICSI scores decreased significantly at weeks 12 and 16 (mean change from baseline -0.91 [95% CI, -1.65 to -0.18] and -0.754 [95% CI, -1.49 to -0.02], respectively). ICPI scores decreased significantly at week 16 (mean change from baseline -0.99 [95% CI, -1.63 to -0.34]). In contrast, there were no significant changes in outcomes in the sham arm. No serious adverse events occurred.

CLINICAL IMPLICATIONS

Fractional CO2 laser treatment in women with vestibular pain resulted in improvement from baseline in multiple key outcome measures of vestibular health.

STRENGTHS AND LIMITATIONS

Strengths of the study were that it was a multisite prospective randomized double-blind, sham-controlled clinical trial that included multiple measures related to vestibular pain and sexual function. Limitations were the nonvalidated primary outcome measure and limited study cohort.

CONCLUSION

Fractional CO2 laser therapy is a safe and effective nonhormonal treatment for vestibular pain.

Management of vaginal laxity through bilateral wall tightening without mucosal excision

BACKGROUND

Vaginal tightening or vaginoplasty has been gaining popularity, while validated methods of evaluation and treatment are still lacking. Herein, we describe a bilateral wall tightening technique for vaginal laxity and evaluate the feasibility of this method.

METHODS

From April 2020 to September 2021, 25 women with vaginal laxity underwent vaginal tightening, and 22 women were included in this retrospective observational study. The inclusion criteria were as follows: participants with at least one delivery and reported vaginal laxity, but without a history of underlying diseases. Vaginal pressure tests and questionnaires were used to evaluate vaginal laxity and sexual quality before and 6 months after the surgery.

RESULTS

The study included 22 women (aged 29-46 years), and the follow-up period was 14.1 ± 3.3 months. The score based on the vaginal laxity questionnaire was improved as a result of surgery (preoperative median: 2.00, interquartile range [IQR]: 1.00-2.00; postoperative median: 5.00, IQR: 5.00-6.25, p < 0.001). The vaginal pressure increased from 2.3 ± 1.8 mm/Hg to 21.4 ± 3.7 mm/Hg. Sexual distress changed from 24.2 ± 8.9-16.1 ± 4.8 after surgery (p < 0.001), and sexual dysfunction with an average score of 20.1 ± 10.6 before surgery improved after the procedure (26.0 ± 10.8, p < 0.001). Women also reported improved scores in desire, arousal, orgasm, and satisfaction. In addition, there were no intraoperative complications or significant events during the follow-up period.

CONCLUSIONS

Bilateral vaginal tightening without mucosal excision is a feasible and effective surgical approach for the management of vaginal laxity.

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

OBJECTIVE

To assess whether CO2 laser treatment is more effective than sham application in relieving the most bothersome symptom (MBS) in women with genitourinary syndrome of menopause (GSM).

DESIGN

Single-centre, sham-controlled, double-blind, randomised trial.

SETTING

A tertiary centre in Belgium.

POPULATION

Sixty women with moderate to severe GSM symptoms.

METHODS

All participants eventually received three consecutive laser and three consecutive sham applications, either first laser followed by sham, or conversely.

MAIN OUTCOME MEASURES

The primary outcome was the participant-reported change in severity of the MBS at 12 weeks. Secondary outcomes included subjective (patient satisfaction, sexual function, urinary function) and objective (pH, Vaginal Health Index Score, in vivo microscopy) measurements assessing the short-term effect and the longevity of treatment effects at 18 months after start of the therapy. Adverse events were reported at every visit.

RESULTS

The MBS severity score decreased from 2.86 ± 0.35 to 2.17 ± 0.93 (-23.60%; 95% CI -36.10% to -11.10%) in women treated with laser compared with 2.90 ± 0.31 to 2.52 ± 0.78 (-13.20%; 95% CI -22.70% to -3.73%) in those receiving sham applications (p = 0.13). There were no serious adverse events reported up to 18 months.

CONCLUSIONS

In women with GSM, the treatment response 12 weeks after laser application was comparable to that of sham applications. There were no obvious differences for secondary outcomes and no serious adverse events were reported.

A Randomized, Placebo-Controlled Trial Evaluating the Single and Combined Efficacy of Radiofrequency and Hybrid Fractional Laser for Nonsurgical Aesthetic Genital Procedures in Post-Menopausal Women

BACKGROUND

The efficacy of interventions that provide long-term relief of genitourinary symptoms of menopause has not been determined.

OBJECTIVES

The authors sought to evaluate radiofrequency and hybrid fractional laser (HFL) treatments for menopausal vulvovaginal symptoms.

METHODS

Thirty-one postmenopausal women completed all treatments and at least 1 follow-up. Outcomes included the Vulvovaginal Symptom Questionnaire (VSQ), Vaginal Laxity Questionnaire (VLQ), Urogenital Distress Short Form, Incontinence Impact Questionnaire (IIQ), Female Sexual Function Index (FSFI), laxity measurements via a vaginal biometric analyzer probe, and gene expression studies.

RESULTS

Mean VSQ score decreased 2.93 (P = 0.0162), 4.07 (P = 0.0035), and 4.78 (P = 0.0089) among placebo, dual, and HFL groups 3 months posttreatment and decreased to 3.3 (P = 0.0215) for dual patients at 6 months. FSFI scores increased in the desire domain for placebo and dual groups and in arousal, lubrication, orgasm, satisfaction, and pain domains for the HFL group 3 and 6 months posttreatment. An increase of 1.14 in VLQ score (P = 0.0294) was noted 3 months and 2.2 (P = 0.002) 6 months following dual treatment. There was also a mean decrease of 15.3 (P = 0.0069) in IIQ score for HFL patients at 3 months. Dual, HFL, and RF treatments resulted in statistically significant decreases in collagen I, elastin, and lysyl oxidase expression.

CONCLUSIONS

Several self-reported improvements were noted, particularly among HFL, dual, and placebo groups 3 and 6 months posttreatment. Objective biopsy analysis illustrated decreased gene expression, suggesting that treatments did not stimulate new extracellular matrix production.

Optical coherence tomography evaluation of vaginal epithelial thickness during CO2 laser treatment: A pilot study

Genitourinary syndrome of menopause (GSM) negatively affects more than half of postmenopausal women. Energy-based therapy has been explored as a minimally invasive treatment for GSM; however, its mechanism of action and efficacy is controversial. Here, we report on a pilot imaging study conducted on a small group of menopause patients undergoing laser treatment. Intravaginal optical coherence tomography (OCT) endoscope was used to quantitatively monitor the changes in the vaginal epithelial thickness (VET) during fractional-pixel CO2 laser treatment. Eleven patients with natural menopause and one surgically induced menopause patient were recruited in this clinical study. Following the laser treatment, 6 out of 11 natural menopause patient showed increase in both proximal and distal VET, while two natural menopause patient showed increase in VET in only one side of vaginal tract. Furthermore, the patient group that showed increased VET had thinner baseline VET compared to the patients that showed decrease in VET after laser treatment. These results demonstrate the potential utility of intravaginal OCT endoscope in evaluating the vaginal tissue integrity and tailoring vaginal laser treatment on a per-person basis, with the potential to monitor other treatment procedures.

Clinical Consensus Statement: Vaginal Energy-Based Devices

ABSTRACT

This clinical consensus statement on vaginal energy-based devices (EBDs) reflects an update by content experts from the American Urogynecologic Society's EBD writing group. In 2019, the American Urogynecologic Society's EBD writing group used a modified Delphi process to assess statements that were evaluated for consensus after a structured literature search. A total of 40 statements were assessed and divided into 5 categories: (1) patient criteria, (2) health care provider criteria, (3) efficacy, (4) safety, and (5) treatment considerations. Of the 40 statements that were assessed, 28 reached consensus and the remaining 12 did not. Lack of evidence was among the main reasons that vulvovaginal EBD treatment statements did not reach consensus. In March 2022, these statements were reassessed using the interim literature.

Fractional Carbon Dioxide Laser Improves Vaginal Laxity via Remodeling of Vaginal Tissues in Asian Women

Background: Vaginal laxity (VL) is characterized by the relaxing of the vaginal wall that affects the quality of life and sexual function of patients. The current management of VL such as Kegel exercises and topical or systemic hormonal replacement results in unsatisfactory outcomes; thus, novel modalities are needed to improve the efficacy. Vaginal fractional carbon dioxide (CO2) laser treatment has shown growing applications for the treatment of VL, but results show nonconformities due to the lack of objective evaluations. In this study, we aimed to validate the clinical efficacy and biophysical benefits of fractional CO2 laser treatment for VL patients with the incorporation of objective approaches. Methods: This is a descriptive study without controls. A total of 29 patients were enrolled and treated with two sessions of FemTouch vaginal fractional CO2 laser, with a one-month interval between sessions. Both subjective and objective measurements, including female sexual function index (FSFI), vaginal health index score (VHIS), vaginal tactile imaging (VTI), and histology were used to validate the clinical efficacy and biophysical benefits after treatment. Results: The overall FSFI scores and VHIS scores after the first and second treatment sessions were significantly higher than the baseline scores (p < 0.01, n = 29). VTI measurements showed a significant increase in maximal pressure resistance (kPa) of both the anterior and posterior vaginal walls at a 10−12-month post-treatment visit compared with pre-treatment controls (p < 0.001; n = 16). Histological examination showed that laser treatment led to increases in the thickness of the stratified squamous epithelium layer and density of connective tissues in the lamina propria. Conclusions: Fractional CO2 vaginal laser treatment can improve both vaginal health and sexual function and restore vaginal biomechanical properties by increasing vaginal tissue tightening and improving vaginal tissue integrity in Asian women. Our data support that fractional CO2 vaginal laser is a valid treatment modality for VL.

CO2 surgical laser for treatment of stress urinary incontinence in women: a randomized controlled trial

BACKGROUND

Stress urinary incontinence is a common condition that can be treated conservatively and/or surgically. Given the risks of surgery, developing effective nonsurgical treatment options would be beneficial. Some studies have suggested that laser therapy may improve or cure stress urinary incontinence. However, there is a lack of sham-controlled randomized controlled trials to judge treatment efficacy.

OBJECTIVE

This study aimed to compare the effects of CO₂ vaginal laser vs sham therapy for treating stress urinary incontinence.

STUDY DESIGN

This was a multicenter, participant-blinded, sham-controlled, parallel group (1:1) superiority randomized controlled trial performed in outpatient clinics in 2 hospitals. We included women aged 18 to 80 years with objective and subjective stress urinary incontinence. Participants had undertaken or declined supervised pelvic floor muscle training. Intervention was performed using a CO₂ fractionated vaginal laser. Participants underwent 3 treatments, 4 weeks apart, with increasing energy and density settings. Sham treatment was performed using an identical technique with a deactivated pedal. The primary outcome was the subjective stress urinary incontinence rate (proportion with leak with cough, sneeze, or laughter) at 3 months after completion of treatment. Secondary outcomes included objective stress urinary incontinence, change in the disease-specific patient-reported outcomes, health-related quality of life, and adverse effects. Categorical outcomes were compared using the chi square test and continuous outcomes using analysis of covariance, adjusting for the baseline score.

RESULTS

There were 52 participants who received laser and 49 who received sham treatment. One participant in each group withdrew from the study before the endpoint, and 2 participants in the laser group did not participate in the follow-up visits. Participant mean age was 53 (34-79) years. Mean body mass index was 26.1 (18.1-49.6); 90% were vaginally parous. At 3 months, there was no difference between the sham and active treatment arm in subjective stress urinary incontinence (46 [96%] vs 48 [98%]; relative risk, 0.98 [95% confidence interval, 0.91-1.05]; P=.55) or in objective stress urinary incontinence (37 [80%] vs 33 [80%]; relative risk, 0.99 [95% confidence interval, 0.81-1.23]; P=.995). Patient-reported outcomes and health-related quality of life were also comparable between the groups. Vaginal bleeding occurred in 3 participants after laser and 1 participant after sham treatment. Pain during treatment did not differ between laser and sham treatment.

CONCLUSION

We were unable to show an improvement in stress urinary incontinence after CO₂ vaginal laser therapy compared with sham treatment.

Fractional Co2 laser for vulvo-vaginal atrophy in gynecologic cancer patients: A valid therapeutic choice? A systematic review

INTRODUCTION

One of the most common adverse events reported by gynecological cancer survivors with spontaneous or iatrogenic menopause is vulvo-vaginal atrophy (VVA). An increasing number of women have this kind of discomfort related to the menopause induced by different cancer therapies. In this regard, fractional CO2 laser may be a valid therapeutic choice for these patients.

METHODS

We performed a literature search of PubMed, EMBASE, SCOPUS and Web of Science databases with search terms of laser CO2 treatment of vulvovaginal atrophy and gynecologic cancer survivors and reviewed major US Society Guidelines to create this narrative review of this topic. Breast, ovarian endometrial and cervical cancers were included.

RESULTS

Nine studies were included. Fractional CO2 laser improves clinical symptoms and sexual function, in terms of VHI (vaginal health index) and FSFI (female sexual function index). Non severe adverse event occurred.

CONCLUSION

According to the best evidence available, fractional CO2 laser treatment for VVA is an effective and safe therapeutic option for gynecological cancer survivors, improving sexual life and quality of life (QoL).

The Clinical Effects of Pixel CO2 Laser on Bladder Neck and Stress Urinary Incontinence

Background: Our study aims to assess Pixel CO2 laser efficacy for female stress urinary incontinence (SUI). Methods: In the study, 25 women with SUI were included and scheduled for vaginal Pixel CO2 Laser (FemiLift™, Alma Lasers, Israel) treatment. All subjects had a baseline and 6-month post-treatment assessment that included three-dimensional perineal ultrasound and validated questionnaires. Results: Data showed that monthly three-session vaginal Pixel CO2 Laser treatment significantly improved SUI symptoms, as evidenced by validated questionnaires, including UDI-6, IIQ-7, ICIQ, and vaginal laxity questionnaire (p < 0.05). The Pixel CO2 Laser efficacy in vaginal treatment was 20/25 (80%), and the perineal sonography showed that laser treatment significantly decreased bladder neck mobility and middle urethral area (during resting and straining). Permanent adverse events were not found. Conclusions: The results of our study suggested that for the treatment of mild to moderate SUI symptoms, Pixel CO2 Laser is effective and safe; however, more studies and a longer follow-up should be conducted to confirm its efficacy and durability.

Laser treatment for genitourinary syndrome of menopause: Scientific Impact Paper No. 72 (July 2022): Scientific Impact Paper No. 72 (July 2022)

Genitourinary syndrome of menopause (GSM) is the term used to describe the group of symptoms including vaginal pain, vaginal dryness, itching, pain during sexual intercourse and fragile vaginal tissues as well as urinary symptoms including urinary frequency, urgency, incontinence, blood in the urine (haematuria) and recurrent urinary tract infections that occur due to a lack of the hormone estrogen. These symptoms can have a significant negative impact on psychosexual issues, sexual function and quality of life in postmenopausal women. Traditionally women have been treated with vaginal lubricants, vaginal moisturisers or low-dose vaginal estrogens. Lasers have been used in the cosmetic industry for collagen remodelling and repair of the skin. Therefore, it has been suggested that laser therapy may be used on the vagina as an alternative treatment for GSM. A review of all the published studies assessing the safety and efficacy of laser therapy for GSM have shown promising beneficial results. The majority of studies to date have been small, short-term, observational studies. However, there are randomised controlled trials underway. Laser treatment may be beneficial for the symptoms of GSM but until more robust evidence is available it should not be adopted into widespread practice, and should be used as part of a research study only.

The evidence behind the use of LASER for genitourinary syndrome of menopause, vulvovaginal atrophy, urinary incontinence and lichen sclerosus: A state-of-the-art review

In recent years, LASER has been introduced as a minimally invasive treatment for a broad range of vaginal and vulvar symptoms and diseases. However, the efficacy and safety of vaginal and vulvar LASER has continuously been questioned. The aim of this study is to create an overview of the current literature and discuss the controversies within the use of LASER for genitourinary syndrome of menopause, vulvovaginal atrophy, urinary incontinence and lichen sclerosus. A search string was built in PubMed. The search was commenced on August 25, 2021 and closed on October 27, 2021. Two authors screened the studies in Covidence for inclusion according to the eligibility criteria in the protocol. The data were extracted from the studies and are reported in both text and tables. This review included 114 papers, of which 15 were randomized controlled trials (RCTs). The effect of LASER as a vaginal treatment was investigated for genitourinary syndrome of menopause in 36 studies (six RCTs), vulvovaginal atrophy in 34 studies (four RCTs) and urinary incontinence in 30 studies (two RCTs). Ten studies (three RCTs) investigated the effect of vulvar treatment for lichen sclerosus. Half of the included RCTs, irrespective of indication, did not find a significant difference in improvement in women treated with vaginal CO₂ or Er:YAG LASER compared with their respective controls. However, most non-comparative studies reported significant improvement after exposure to vaginal or vulvar LASER across all indications. Included studies generally had a short follow-up period and only a single RCT followed their participants for more than 6 months post treatment. Adverse events were reported as mild and transient and 99 studies including 51 094 patients provided information of no serious adverse events. In conclusion, this review found that the effect of vaginal and vulvar LASER decreases with higher study quality where potential biases have been eliminated. We therefore stress that all patients who are treated with vaginal or vulvar LASER should be carefully monitored and that LASER for those indications as a treatment should be kept on a research level until further high-quality evidence is available.

Short-Term Efficacy and Safety of Non-Ablative Laser Treatment Alone or with Estriol or Moisturizers in Postmenopausal Women with Vulvovaginal Atrophy

BACKGROUND

Among treatments for vulvo-vaginal atrophy (VVA), there is a new kind of energy-based device, the non-ablative CO2 laser.

AIM

This study aimed to assess the efficacy and safety of the non-ablative CO2 laser in menopausal women with VVA as a monotherapy or in association with vaginal estriol or moisturizer.

METHODS

Seventy-five women with VVA received laser treatment (Laser group), laser plus estriol gel (Laser+E) or laser plus moisturizers (Laser+M). The study protocol consisted of 3 monthly laser sessions (t0, t1, t2) and a gynecological examination at baseline and 1 month after last laser treatment (t3). Objective measures included VHI (Vaginal Health Index) and VuHI (Vulvar Health Index); subjective symptoms of VVA (Dryness, Burning, Itching, Dysuria) evaluated via visual analog scales, sexual function evaluated by FSFI (Female Sexual Function Index), FSDS (Female Sexual Distress Score) and MENQOL (Mopause-specific Quality Of Life). Adverse events and discomfort encountered during the procedure were also assessed.

OUTCOMES

Primary outcomes were the evaluation of VHI and VuHI and secondary outcomes were changes in VVA symptoms (VAS), sexual function (MENQOL, FSFI, FSDS) and discomfort during the procedure.

RESULTS

Seventy-five women (25 in Laser, 25 in Laser+E and 25 in Laser+M group) completed the study. At t3, mean VHI, VuHI, dryness, burning and itching VAS scores improved significantly with no differences between the groups. The lubrication domain of FSFI improved significantly only in the Laser+M group, while the pain domain improved significantly in all women with no differences between the groups. FSFI and FSDS overall scores and MENQOL sexual domain improved in all women with no significant difference between the groups. The mean score of the pain during the procedure was low at t0 and did not change throughout the study.

CLINICAL IMPLICATIONS

This study extends knowledge concerning the effectiveness of a new non-ablative CO2 laser in post-menopausal women with VVA.

STRENGTHS & LIMITATIONS

This is one of the first studies on this kind of laser and is the first to compare the effectiveness of laser treatment alone or in combination with vaginal estriol or moisturizers. Parameters of VVA and sexual function were evaluated using validated tools. Study limitations include short follow-up time, the limited number of participants and the absence of a sham-controlled group.

CONCLUSION

Non-ablative CO2 laser seems to be an effective treatment for VVA in menopausal women. Our preliminary data shows that it can be effective as monotherapy or with adjuvant treatments.

CO2-Laser therapy and Genitourinary Syndrome of Menopause: A Systematic Review and Meta-Analysis

BACKGROUND

Genitourinary syndrome of menopause (GSM) is a widespread condition with a great impact on quality of life and self-image.

AIM

We aimed to systematically review the current literature on CO2-Laser therapy efficacy for the treatment of GSM.

METHODS

MEDLINE and Embase databases were systematically queried in December 2020 Studies included women with a diagnosis of Vulvo-Vaginal Atrophy (VVA) or GSM without an history of gynaecological and/or breast cancer, pelvic organ prolapse staged higher than 2, pelvic radiotherapy or Sjogren's Syndrome. The quality of the evidence was assessed with the Cochrane risk of bias tool. This study is registered on PROSPERO, number CRD42021238121.

OUTCOMES

Effects of CO2-Laser therapy on GSM symptoms assessed through subjective or objective efficacy measurement methods.

RESULTS

A total of 803 articles were identified. Of these, 25 studies were included in this review for a total of 1,152 patients. All studies showed a significant reduction in VVA and/or GSM symptoms (dryness, dyspareunia, itching, burning, dysuria). The pooled mean differences for the symptoms were: dryness -5.15 (95% CI:-5.72,-4.58; P < .001; I2:62%; n = 296), dyspareunia -5.27 (95% CI:-5.93,-4.62; P < .001; I2:68%; n = 296), itching -2.75 (95% CI:-4.0,-1.51; P < .001; I2:93%; n = 281), burning -2.66 (95% CI:-3.75, -1.57; P < .001; I2:86%; n = 296) and dysuria -2.14 (95% CI:-3.41,-0.87; P < .001; I2:95%; n = 281). FSFI, WHIS and VMV scores also improved significantly. The pooled mean differences for these scores were: FSFI 10.8 (95% CI:8.41,13.37; P < .001; I2:84%; n = 273), WHIS 8.29 (95% CI:6.16,10.42; P < .001; I2:95%; n = 262) and VMV 30.4 (95% CI:22.38,38.55; P < .001; I2:24%; n = 68). CO2-Laser application showed a beneficial safety profile and no major adverse events were reported.

CLINICAL IMPLICATIONS

Vaginal laser treatment resulted in both a statistically and clinically significant improvement in GSM symptoms. FSFI improved significantly in all 8 included studies but it reached a clinically relevant level only in 2 of them.

STRENGTHS & LIMITATIONS

The strength of the current meta-analysis is the comprehensive literature search. We reported data from a high number of patients (1,152) and high number of laser applications (more than 3,800). The main limitations are related to the high heterogeneity of the included studies investigating laser effects. Moreover, most of them are single center and nonrandomized studies.

CONCLUSION

The data suggest that CO2-Laser is a safe energy-based therapeutic option for the management of VVA and/or GSM symptoms in postmenopausal women; however, the quality of the body of evidence is "very low" or "low".

Long-Term Follow-Up of Fractional CO2 Laser Therapy for Genitourinary Syndrome of Menopause in Breast Cancer Survivors

(1) Background: The objective of this study was to determine the long-term efficacy of fractional CO₂ laser therapy in breast cancer survivors. (2) Methods: This was a single-arm study of breast cancer survivors. Participants received three treatments of fractional CO₂ laser therapy and returned for a 4 week follow-up. Participants were contacted for follow-up at annual intervals. The Vaginal Assessment Scale (VAS), the Female Sexual Function Index (FSFI), the Female Sexual Distress Scare Revised (FSDS-R), the Urinary Distress Inventory (UDI), and adverse events were collected and reported for the two-year follow-up. The changes in scores were compared between the four-week and two-year and the one-year and two-year follow-ups using paired t-tests. (3) Results: In total, 67 BC survivors were enrolled, 59 completed treatments and the four week follow-up, 39 participated in the one-year follow-up, and 33 participated in the two-year follow-up. After initial improvement in the VAS from baseline to the four week follow-up, there was no statistically significant difference in the VAS score (mean Δ 0.23; 95% CI [−0.05, 0.51], p = 0.150) between the four week follow-up and the two-year follow-up. At the two-year follow-up, the FSFI and FSDS-R scores remained improved from baseline and there was no statistically significant change in the FSFI score (mean Δ −0.83; 95% CI [−3.07, 2.38] p = 0.794) or the FSDS-R score (mean Δ −2.85; 95% CI [−1.88, 7.59] p = 0.227) from the one to two-year follow-up. The UDI scores approached baseline at the two-year follow-up; however, the change between the one- and two-year follow-ups was not statistically significant (mean Δ 4.76; 95% CI [−1.89, 11.41], p = 0.15). (4) Conclusions: Breast cancer survivors treated with fractional CO₂ laser therapy have sustained improvement in sexual function two years after treatment completion, suggesting potential long-term benefit.

Effects of oxytocin versus promestriene on genitourinary syndrome: a pilot, prospective, randomized, double-blind study

OBJECTIVES

In this pilot, prospective, randomized, double-blind study, the authors compared the efficacy of oxytocin with promestriene in improving vaginal atrophy of Genitourinary Syndrome of Menopause (GSM).

METHODS

A total of 51 postmenopausal women with symptoms of GSM were evaluated. They were randomized into two groups: oxytocin (25 patients) and promestriene (26 patients) and were evaluated before and after 90 days of treatment; the evaluation was based on the domains of the Female Sexual Function Index (FSFI) (lubrication, satisfaction, and pain during sexual intercourse), clinical visual examination, and vaginal wall thickness.

RESULTS

After the use of the medications, both groups showed significant improvement in the three evaluated FSFI domains (p < 0.05) and there was no significant difference between the groups (p > 0.05). On clinical examination, the medications improved all the evaluated parameters but without statistical significance (p > 0.05). The evaluation of the thickness of the vaginal epithelium showed that both treatments led to increase in the vaginal epithelium (p < 0.05); however, the efficacy of promestriene was higher than that of oxytocin (p < 0.05).

CONCLUSIONS

Both medications were effective, however, studies with larger samples and longer follow-ups are needed to confirm the clinical applicability.

Female Genitourinary Treatments in Aesthetics

Female genitourinary treatments in aesthetics utilize energy-based treatments and other non-invasive modalities. These include CO2 and Er:YAG lasers, radiofrequency (RF), high-intensity focused electromagnetic energy (HIFEM), hyaluronic acid (HA) injection, platelet-rich plasma (PRP), and silicone thread treatments with an objective to treat sexual dysfunction and symptoms of genitourinary syndrome associated with menopause (GSM), which include atrophic vaginitis, urinary incontinence, and vulvovaginal laxity that is characterized by vaginal dryness, thinning of the epithelium, laxity, prolapse, incontinence, dyspareunia, and increased bacterial infections. The body of evidence is growing for the use of these modalities to improve signs and symptoms of GSM and sexual function, as well as rejuvenate the appearance of external female genitalia. We reviewed the currently available modalities in this rapidly advancing area of expertise.

Alternative and non-hormonal treatments to symptoms of menopause

Ovarian function can start to decline a few years before the eventual cessation of the menstrual cycle. The average age of menopause in the UK is 51 years, and it is a retrospective diagnosis after 12 months of amenorrhoea. Women can experience many symptoms such as vasomotor and vulvovaginal symptoms that impact them physically, psychologically, sexually and thus their overall wellbeing. Women may have medical contraindications to hormonal therapy or may prefer non-hormonal or alternative treatments. This review looks at the evidence, efficacy, and safety of a range of complementary or alternative treatments and non-hormonal pharmacological treatments for the treatment of vasomotor symptoms and vulvovaginal atrophy of menopause.

Treatment of Vulvovaginal Atrophy with Fractional CO2 Laser: Evaluating Real-World Data

Objective: We aimed to evaluate real-world data for the use of fractional CO₂ laser therapy for treating symptoms of vulvovaginal atrophy (VVA). Background: VVA is widespread and can reduce the patients' quality of life. There is a lack of data regarding its therapy with laser, especially for daily practice (i.e., real-world data). Methods: Thirty-six patients were treated in a single medical center. They consisted of pre- and postmenopausal women and received three fractional CO₂ laser therapy treatments with 3-6 weeks between each treatment. Each patient financed the treatment privately. The symptoms pain, pruritus, dyspareunia, burning, dryness, and dysuria were recorded with a visual analog scale (1-10) before the first, second, and third laser treatment. The data were examined retrospectively. Results: Pain was reduced from a mean of 2.5 points (minimum 0, maximum 9 points) to 1.1 (minimum 0, maximum 8 points) before the third laser treatment. Pruritus showed a mean score of 3.8 (minimum 0, maximum 10 points). This decreased to 1.4 (minimum 0, maximum 8 points). Dyspareunia scored a mean of 6.8 (minimum 0, maximum 10 points). After two laser therapies, the score was 3.3 (minimum 0, maximum 8 points). Burning showed 4.2 points (minimum 0, maximum 10 points). Having experienced two laser therapy sessions, the patients scored 1.5 (minimum 0, maximum 9 points) points. The severity of dryness dropped from 6.5 (minimum 0, maximum 10 points) to 3.3 (minimum 0, maximum 9 points). Dysuria was stated with 1.8 points (minimum 0, maximum 10 points) before the first and 0.5 points (minimum 0, maximum 6 points) before the third laser therapy. All changes showed statistical significance (p < 0.002). Conclusions: This real-world data propose fractional CO₂ laser to reduce VVA-associated genital discomfort, thus being a valuable therapy option for pre- and postmenopausal women.

Efficacy and Safety of Laser Therapy for the Treatment of Genitourinary Syndrome of Menopause: A Protocol for Systematic Review and Meta-Analysis of Clinical Trials

Laser therapy has been proposed to improve the symptoms of genitourinary syndrome of menopause (GSM), especially in women who do not accept hormonal therapy or are at a high risk of complications if they undergo hormonal therapy. However, studies evaluating the effectiveness and safety of laser treatment for GSM have shown controversial results. Thus, we aimed to determine the efficacy and safety of laser therapy in post-menopausal women with GSM. We have developed a protocol according to the Preferred Reporting Items for Systematic Review and Meta-analysis Protocol using the population, intervention, comparison, outcome, and study design (PICOS) framework for post-menopausal women who have received no treatment, laser therapy, placebo, or vaginal estrogen for GSM. As per our protocol, randomized controlled trials and quasi-randomized trials, regardless of language of publication, will be searched in PubMed, Embase, Scopus, Web of Science, Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature, and clinicaltrials.gov. Gray literature will be searched in Open Gray and Google Scholar. The reference lists will be scanned for additional trials, and the authors will be contacted if necessary. Outcome data reported in a trial registry, even when no published results were available, will be analyzed. The search will be performed using key terms, such as “post-menopausal women,” “menopausal genitourinary syndrome,” “vulvovaginal atrophy,” and “laser therapy.” Two review authors will independently screen the titles and abstracts, while three others will independently evaluate the full text of each study to determine its eligibility for this systematic review (SR). Any disagreement will be resolved through discussion and consensus. Data extraction will be performed independently using a standardized data collection form. Clinical outcomes, including vaginal atrophy, vaginal pH, dryness, dyspareunia, itching, burning, dysuria, urinary frequency, urinary urgency, and urinary incontinence, will be systematically evaluated. We will not perform a separate search for adverse effects; instead, we will consider the adverse effects described in the included studies. Furthermore, we will summarize the effects of dichotomous outcomes as risk ratios with 95% confidence intervals. On the other hand, continuous outcomes will be summarized by expressing treatment effects as a mean difference with standard deviation or as a standardized mean difference when different scales were used to measure the same outcome. We will use the Cochrane Risk of Bias 2 tool for bias assessment and the Grading of Recommendations Assessment, Development and Evaluation approach to rate the overall certainty of evidence. Review Manager 5.3.5 will be used for quantitative data synthesis, subgroup analysis, sensitivity analysis, meta-regression, and risk of bias assessment. The SR findings will provide highly relevant evidence through the synthesis of well-designed and robust clinical trials on the effectiveness and safety of laser therapy in GSM. The Prospective Register of Systematic Reviews (PROSPERO) registration number (2021) of the SR is CRD42021253605.

Use of a vaginal CO2 laser for the management of genitourinary syndrome of menopause in gynecological cancer survivors: a systematic review

Genitourinary syndrome of menopause (GSM) may arise from the hypoestrogenism caused by ovarian function destruction following gynecological cancer treatments. GSM may also be present in menopausal women and its symptoms might be exacerbated by cancer treatments. Historically, patients with hormone-dependent gynecological cancer and physicians have been less comfortable using vaginal estrogen due to fear of recurrence. CO₂ vaginal laser therapies have demonstrated efficacy as a non-hormonal alternative for GSM treatment in healthy menopausal patients. The objective of this study was to evaluate the data on the effect of a CO₂ vaginal laser for the management of GSM in gynecological cancer patients. Databases searched included MEDLINE, Embase, PubMed, Cochrane and Google Scholar. Selected studies assessed use of a CO₂ vaginal laser in gynecological cancer patients with GSM. A total of 269 studies were retrieved. Four studies met the inclusion criteria. Each study followed a different type of CO₂ vaginal laser protocol for the management of GSM in gynecological cancer patients. There are no randomized controlled trials that assess the use of a CO₂ vaginal laser in gynecologic cancer patients. The number of published gynecological cancer patients treated with a CO₂ laser for the management of GSM is extremely limited (N < 100). There is a lack of literature on the impact and safety of vaginal CO₂ laser use to manage GSM in gynecologic cancer patients.

Effect of Fractional Carbon Dioxide Laser vs Sham Treatment on Symptom Severity in Women With Postmenopausal Vaginal Symptoms: A Randomized Clinical Trial

IMPORTANCE

Postmenopausal vaginal symptoms are common and frequently detrimental to a woman's quality of life. Fractional carbon dioxide vaginal laser is increasingly offered as a treatment, but the efficacy remains unproven.

OBJECTIVE

To determine the efficacy of fractional carbon dioxide laser for treatment of vaginal symptoms associated with menopause.

DESIGN, SETTING, AND PARTICIPANTS

A double-blind, randomized, sham-controlled trial with 12-month follow-up was undertaken at a single tertiary referral hospital in Sydney, Australia. Enrollment commenced on September 19, 2016, with final follow-up on June 30, 2020. Participants were postmenopausal women with vaginal symptoms substantive enough to seek medical treatment. Of 232 participants approached, 85 were randomized.

INTERVENTIONS

Three treatments using a fractional microablative carbon dioxide laser system performed 4 to 8 weeks apart, with 43 women randomized to the laser group and 42 to the sham group.

MAIN OUTCOMES AND MEASURES

The co-primary outcomes were symptom severity assessed using a visual analog scale (VAS; range, 0-100; 0 indicates no symptoms and 100 indicates the most severe symptoms) and the Vulvovaginal Symptom Questionnaire (VSQ; range, 0-20; 0 indicates no symptoms and 20 indicates the most severe symptoms) at 12 months. The minimal clinically important difference was specified as a 50% decrease in both VAS and VSQ severity scores. There were 5 prespecified secondary outcomes, including quality of life (range, 0-100; higher scores indicate better quality of life), the Vaginal Health Index Score (range, 5-25; higher scores indicate better health), and vaginal histology (premenopausal or postmenopausal status).

RESULTS

Of 85 randomized participants (mean [SD] age, 57 [8] years), 78 (91.7%) completed the 12-month follow-up. From baseline to 12 months, there was no significant difference between the carbon dioxide laser group and the sham group in change in symptom severity (VAS score for overall vaginal symptoms: -17.2 vs -26.6; difference, 9.4 [95% CI, -28.6 to 47.5]; VAS score for the most severe symptom: -24.5 vs -20.4; difference -4.1 [95% CI, -32.5 to 24.3]; VSQ score: -3.1 vs -1.6; difference, -1.5 [95% CI, -5.9 to 3.0]). There were no significant differences between the laser and sham group in the mean quality of life score (6.3 vs 1.4; difference, 4.8 [95% CI, -3.9 to 13.5]) and Vaginal Health Index Score (0.9 vs 1.3; difference, -0.4 [95% CI, -4.3 to 3.6]) or in histological comparisons between laser and sham treatment groups. There were 16 adverse events in the laser group and 17 in the sham group, including vaginal pain/discomfort (44% vs 68%), spotting, discharge, and lower urinary tract symptoms. No severe adverse events were reported in either group.

CONCLUSIONS AND RELEVANCE

Among women with postmenopausal vaginal symptoms, treatment with fractional carbon dioxide laser vs sham treatment did not significantly improve vaginal symptoms after 12 months.

Efficacy of CO2 laser treatment in postmenopausal women with vulvovaginal atrophy: A meta-analysis

OBJECTIVE

To explore the efficacy of CO₂  laser treatment in postmenopausal women with vulvovaginal atrophy.

METHOD

PubMed, Embase, Cochrane Library and Web of Science were searched to June 9, 2020. Prospective studies on the efficacy of CO₂  laser treatment were included. Two researchers independently reviewed articles and extracted data. Heterogeneity test was conducted for each outcome indicator. Sensitivity analysis was performed in all models.

RESULTS

Twelve articles including 459 participants were enrolled. Compared with baseline, vaginal health indeices (VHIs) were significantly higher at the 1-, 3-, 6-, and 12-month follow ups (P < 0.001). For VVA severity, the visual analog scale scores for vaginal dryness at 1-, 3-, 6-, and 12-month follow-ups (P < 0.050), vaginal burning, itching, and dysuria at 1-month follow up (P < 0.001), and dyspareunia at 1-, 3-, 6-, and 12-month follow-ups (P < 0.001) were all significantly lower. For FSFI, total scores at 1-, 3-, 6-, and 12-month follow ups (P < 0.001), and the scores in desire, arousal, lubrication, orgasm, satisfaction, and pain at 1-month follow up (P < 0.050) were all significantly higher. For quality of life, the PCS12 and MCS12 scores were all significantly higher (P < 0.050) at the 1-month follow up.

CONCLUSION

CO₂  laser treatment may be effective for postmenopausal women with VVA symptoms in improving quality of life and sexual function.

Pharmaceutical and Energy-Based Management of Sexual Problems in Women

This article summarizes and critiques the evidence for use of available pharmacotherapies (vasoactive, psychoactive, and hormonal medications) and energy-based therapies (laser, radiofrequency, shockwave, and neurostimulation) for treatment of female sexual dysfunction. The enthusiasm with which energy-based treatments for sexual dysfunction have been adopted is disproportionate to the amount of data currently available to support their clinical use. Pharmacotherapy for female sexual dysfunction has considerably more research evidence to justify its use. Patients must be empowered to make an informed, autonomous determination as to whether the risk/reward ratio favors the use of pharmacotherapy, energy-based therapy, or some other treatment intervention.

Treatment of Rectovaginal Fistula Using Fractionate CO2 Vaginal Laser: A Case Series

Background: Rectovaginal fistulas (RVFs) are abnormal tracts that connect the lower gastrointestinal tract with the vagina. They can result from obstetric trauma, infection, local surgeries, cancer, radiation damage, and Crohn's disease. Despite the advances in surgical and clinical treatment, there is no consensus regarding the best line of treatment. Objective: To report five cases of patients with RVF submitted to intravaginal CO₂ fractional laser treatment, as a complementary and additional therapeutic option in this scenery. Materials and methods: Five laser sessions with monthly intervals followed by complete evaluation through clinical examination and magnetic resonance imaging of the pelvis were performed for all patients. Results: Three patients had complete resolution of symptoms after the end of planned vaginal laser sessions, whereas two patients reported significant improvement in symptoms. Four patients who had stopped having sex due to their condition admitted to resuming regular sexual activity. In addition, all five patients had closure of the fistulous track confirmed by pelvic MRI. No adverse events from vaginal laser therapy were reported by any of the patients. Conclusions: We believe this method to be a complementary, promising, and safe therapeutic alternative for the management of RVF. It may potentially enable return to regular sexual activity. Future studies using this therapeutic strategy are needed to confirm the efficacy and safety of this method in this clinical setting. Clinical trial registration no.: CAAE 93673618.4.0000.5133.

Clobetasol Compared With Fractionated Carbon Dioxide Laser for Lichen Sclerosus: A Randomized Controlled Trial

OBJECTIVE

To compare 6-month safety and efficacy outcomes of fractionated CO2 laser (laser) with topical clobetasol propionate (steroid) for treatment of symptomatic vulvar lichen sclerosus.

METHODS

We conducted a single-center randomized controlled trial that compared fractionated CO2 laser with steroid treatment for patients with biopsy-proven lichen sclerosus. Randomization was stratified by prior clobetasol propionate use. The primary outcome was mean change in Skindex-29 score at 6 months. A total sample size of 52 participants were recruited to detect a mean difference of 16 points on the Skindex-29 (SD±22) with 80% power, based on a one-sided two-sample t test with α=0.05, accounting for 10% attrition. Secondary outcomes included validated subjective and objective measures. Intention-to-treat, per protocol, and regression analysis based on prior steroid exposure were performed.

RESULTS

From October 2015 to July 2018, 202 women were screened, 52 were randomized, and 51 completed a 6-month follow-up. No significant difference was found in baseline demographics, symptoms, and physician assessment scores. There was greater improvement in the Skindex-29 score in the laser arm at 6-months (10.9 point effect size, 95% CI 3.42-18.41; P=.007). Overall, 89% (23/27) of patients in the laser group rated symptoms as being "better or much better" compared with 62% (13/24) of patients in the steroid group, P=.07. More patients (81%, 21/27) were "satisfied or very satisfied" with laser treatment compared with steroid treatment (41%, 9/24); P=.01. After stratification for previous steroid use, the significant change of Skindex-29 score was only seen in the previously exposed group. There was one adverse event in each group: minor burning and blistering at the laser site and reactivation of genital herpes 1 week after starting steroid.

CONCLUSION

Fractionated CO2 laser treatment showed significant improvement in subjective symptoms and objective measures compared with clobetasol propionate, without serious safety or adverse events at 6 months.

Microablative fractional radiofrequency for the genitourinary syndrome of menopause: protocol of randomised controlled trial

INTRODUCTION

Menopause is a physiological and progressive phenomenon secondary to decreased ovarian follicular reserve. These changes have consequences: vaginal dryness, dyspareunia, discomfort, burning and irritation, vulvovaginal pruritus, dysuria and increased frequency of genitourinary infections. The therapy more suitable for vaginal symptoms in postmenopause yet is the use of a topical hormone. However, the prescription of topical oestrogens should also be avoided in women with a history of breast cancer, oestrogen-sensitive tumours and thromboembolism, emphasising the necessity of alternative treatments. Recently, physical methods, such as laser and radiofrequency (RF), in their non-ablative, ablative and microablative forms have been used in the vaginal mucosa to promote neocolagenesis and neoelastogenesis. This randomised study aims to compare the efficiency of microablative fractional RF (MAFRF) treatment with vaginal oestrogens and no treatment.

METHODS AND ANALYSES

This randomised, controlled clinical intervention trial with an open label design comparing the treatment of MAFRF with vaginal oestrogens and no treatment. Four important moments were considered to evaluate treatment results (T0, T1, T2 and T3). The primary outcome includes vulvovaginal atrophy (vaginal pain, burning, itching, dryness, dyspareunia and dysuria), and the secondary outcomes will be sexual function, vaginal health (epithelial integrity, vaginal elasticity, moisture, fluid volume and vaginal pH) and quality of life.

ETHICS AND DISSEMINATION

Due to the nature of the study, we obtained approval from the ethics committee. All participants must sign an informed consent form before randomisation. The results of this study will be published in peer-reviewed journals. The data collected will also be available in a public repository of data.

Carbon Dioxide Laser Vulvovaginal Rejuvenation: A Systematic Review

Genitourinary syndrome of menopause (GSM) causes significant symptomatic aggravation that affects the quality of life (QoL). Vulvovaginal atrophy (VVA), the hallmark of GSM, is managed with topical non-hormonal therapy, including moisturizers and lubricants, and topical estrogen application. Patients not responding/being unsatisfied with previous local estrogen therapies are candidates for a noninvasive modality. Carbon dioxide (CO2) laser therapy, especially the fractionated type (FrCO2), has drawn considerable attention over the past two decades as a non-invasive treatment for GSM. This systematic review describes the accumulated evidence from 40 FrCO2 laser studies (3466 participants) in GSM/VVA. MEDLINE, Scopus and Cochrane databases were searched through April 2021. We analyze the effects of FrCO2 laser therapy on symptoms, sexual function, and QoL of patients with GSM/VVA. As shown in this review, FrCO2 laser therapy for GSM shows good efficacy and safety. This modality has the potential to advance female sexual wellness. Patient satisfaction was high in the studies included in this systematic review. However, there is a lack of level I evidence, and more randomized sham-controlled trials are required. Furthermore, several clinical questions, such as the number of sessions required that determine cost-effectiveness, should be addressed. Also, whether FrCO2 laser therapy may exert a synergistic effect with systemic and/or local hormonal/non-hormonal treatments, energy-based devices, and other modalities to treat GMS requires further investigation. Lastly, studies are required to compare FrCO2 laser therapy with other energy-based devices such as erbium:YAG laser and radiofrequency.

Vaginal laser therapy for genitourinary syndrome of menopause - systematic review

BACKGROUND

Genitourinary syndrome of menopause (GSM) can have a great impact on the quality of life (QOL), and affects between 53.8% and 90% of postmenopausal women. The literature suggests that vaginal laser therapy could be an effective treatment for GSM symptoms, but its efficacy and safety have not been established and international societies do not endorse its use. Despite that, there has been an increase in the use of vaginal laser therapy globally over the last decade.

OBJECTIVE

The objective of this review is to evaluate the literature which assesses the efficacy and safety of the vaginal laser therapy in the treatment of GSM.

METHODS

A comprehensive literature search was conducted electronically using Embase and PubMed to retrieve studies assessing evidence for the efficacy and safety of vaginal laser therapy for GSM or vulvovaginal atrophy up to June 2021.

RESULTS

A total of 64 studies were finally included in the review. There were 10 controlled intervention studies, 7 observational cohort and cross-sectional studies and 47 before-after studies without a control group.

CONCLUSION

Vaginal laser seems to improve scores on the Visual Analogue Scale (VAS), Female Sexual Function Index (FSFI) and Vaginal Health Index (VHI) in GSM over the short term. Safety outcomes are underreported and short-term. Further well-designed clinical trials with sham-laser control groups and evaluating objective variables are needed to provide the best evidence on efficacy.

Fractional CO2 laser treatment effect on cervicovaginal lavage zinc and copper levels: a prospective cohort study

BACKGROUND

The basic principle of vaginal laser therapy is the rejuvenation of the affected tissue. Zinc and copper are essential nutritional trace elements and have a key role in connective tissue homeostasis. We aimed to investigate the effect of vaginal, fractional CO₂ laser treatment on cervicovaginal lavage (CVL) zinc and copper levels.

METHODS

Twenty-nine postmenopausal women with symptoms of vaginal dryness were enrolled in our prospective cohort study. Three treatments with MonaLisa Touch CO₂ laser system were performed four weeks apart. At each treatment CVL was collected, Vaginal Health Index (VHI) was obtained, and Visual Analog Scale (VAS) for vaginal dryness was assigned by patients. Zinc and copper concentrations were measured with optical emission spectrometry before each treatment and six weeks after the 3rd treatment.

RESULTS

The VHI scores significantly improved after each laser treatment (mean ± SD VHI score, 13.03 ± 4.49 before vs. 15.55 ± 4.35 after the 1st, 17.79 ± 4.57 after the 2nd and 19.38 ± 4.39 after the 3rd treatment, P < 0.01). Similarly, VAS scores reflected improvement (mean ± SD VAS score 6.59 ± 2.86 before vs. 4.17 ± 2.86 after the 1st, 2.45 ± 2.43 after the 2nd and 1.41 ± 1.94 after the 3rd treatment, P < 0.01). CVL zinc levels were significantly higher compared to copper levels (0.06 ± 0.04 vs. 0.006 ± 0.006 mg/L, P < 0.01) at baseline. While copper levels remained the same through treatments, the CVL zinc level was significantly higher after the second laser treatment compared to the baseline.

CONCLUSIONS

Fractional CO₂ laser treatment of the vagina impacts CVL zinc and copper levels differently. While CVL copper levels were not different after each laser treatment, zinc levels were significantly higher after the second treatment before returning to baseline values.
