Comparison of the effect of noninvasive radiofrequency with vaginal estrogen and vaginal moisturizer in the treatment of vulvovaginal atrophy in postmenopausal women: a randomized clinical trial

OBJECTIVE

To compare the effect of noninvasive radiofrequency (RF) with vaginal estrogen (E), and vaginal moisturizer (M) on improving vulvovaginal atrophy (VVA) in women with genitourinary syndrome of menopause.

METHODS

A total of 32 postmenopausal women who met the inclusion criteria were randomized into three intervention arms to receive one of the following treatments: three sessions of noninvasive RF therapy (RF arm); intravaginal estriol cream 1 mg applied daily for 2 weeks, followed by 1 mg applied two times weekly or 1 mg of estradiol vaginal fast-dissolving film applied daily for 2 weeks, followed by 1 mg applied two times weekly (E arm); and intravaginal moisturizer two times a week (M arm). Assessments at baseline and after 4 months were conducted using Vaginal Health Index score, Vaginal Maturation, visual analog scale for VVA symptoms (dyspareunia, dryness, and burning), and Menopause Rating Scale (MRS) for urogenital symptoms. Vaginal wall biopsies were administered to participants who consented, pretreatment and posttreatment (at baseline and after 4 months of follow-up).

RESULTS

After 4 months, the Vaginal Health Index showed an increase of 6.6 points in mean total score in the RF arm, also in the E arm (+7.3 points), with no significant improvement in the M arm (+1.5 points) (interaction effect: RF, E ≠ M, P < 0.001). Regarding vaginal maturation, there was a significant increase in superficial cells in the E arm (+31.3), with no significant changes in the RF (+9.3) and M (-0.5) arms (interaction effect: E ≠ M, P < 0.001). Vaginal pH decreased significantly in the E arm (-1.25), with a similar response in the RF arm (-1.7), with no significant improvement in the M arm (-0.25) (interaction effect: RF, E ≠ M, P < 0.001).There was a significant improvement in the MRS score for VVA symptoms in the three intervention arms, with no predominance of any arm, whereas the improvement in the total MRS score for urogenital symptoms showed a predominance of the RF arm (ΔRF: -7.8; ΔE: -3.5; ΔM: -2.3; RF ≠ E, M). According to histopathologic analysis, there was no statistically significant increase in glycogenation ( P = 0.691) or epithelial cone height ( P = 0.935), despite an increase in the median delta (difference between pretreatment and posttreatment) in the three intervention arms (glycogenation: RF arm Δ = +118.4%; E arm Δ = +130.9%; M arm Δ = +24.9%; epithelial cone height: RF arm Δ = +33.5%; E arm Δ = +18.6%; M arm Δ = +22.3%).

CONCLUSION

The effect of noninvasive RF on the treatment of vulvovaginal symptoms of genitourinary syndrome of menopause was similar to vaginal estrogen, except for hormonal cytology, and superior to vaginal moisturizer, with improvement in some histomorphometric parameters. These findings are promising, especially for the population that cannot or prefers not to use vaginal estrogen therapy.

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.

Mini-review: Modern Concept of Pelvic Organ Prolapse

Symptomatic pelvic organ prolapse (POP) has been increasing in recent years for both developed and developing countries. By 2050, as the adult population grows, the number of women with symptomatic POP will increase by 46%. Due to the increasing number of complications after surgery among women with POP, the current understanding of treatment has become extremely important for researchers and practitioners. There are many novel conservative and surgical treatment approaches under investigation. However, some primary surgical treatments show an approximate 30–50% risk of repeated pelvic floor reconstruction. Therefore, the review aims to summarize several conservative treatment options and identify critical areas of need for future research.

Genitourinary Syndrome of Menopause: Epidemiology, Physiopathology, Clinical Manifestation and Diagnostic

Genitourinary syndrome of menopause (GSM) is a term used to define a compilation of signs and symptoms arising from decreased estrogenic stimulation of the vulvovaginal and lower urinary tract. Among 27–84% of women in postmenopausal are affected for symptoms of GSM, and these can unquestionably impair health, sexual function, consequently the quality of life of these women. The main signs and symptoms of GSM include, among others, burning, irritation, vulvovaginal dryness, dyspareunia, urinary symptoms of urgency, dysuria, or recurrent urinary tract infection. The diagnosis can be made through anamnesis, questionnaires, physical exams, and, sometimes, complementary exams. Objective vaginal assessment is essential and can be complemented by using the Vaginal Health Index (VHI), Vaginal Maturation Index (VMI), or vaginal pH measurement. The acknowledgment of this condition by health professionals is crucial for its identification and proper management and exclusion of other conditions that make a differential diagnosis with it.

Vaginal Rejuvenation: A Retrospective Review of Lasers and Radiofrequency Devices

BACKGROUND

Vaginal rejuvenation is a topic of interest to multiple specialties, including dermatologists, plastic and reconstructive surgeons, urologists, and gynecologists. Evidence suggests that minimally invasive, energy-based devices-radiofrequency and laser therapy-are effective at vaginal tightening and decreasing symptoms of genitourinary syndrome of menopause (GSM) and/or vulvovaginal atrophy (VVA).

MATERIALS AND METHODS

A systematic review was completed using PubMed in November 2018 with search terms "vaginal" or "vagina" and "rejuvenation" or "tightening" or "laxity" or "radiofrequency" or "laser," as well as "genitourinary syndrome of menopause," "pelvic prolapse," "atrophic vaginitis," "vulvovaginal atrophy," "sexual function," "urinary incontinence," and "radiofrequency" or "laser." Inclusion criteria were articles written in English and clinical trials or case reports/series dealing with human subjects.

RESULTS

We identified 59 studies (3,609 women) treated for vaginal rejuvenation using either radiofrequency or fractional ablative laser therapy. Studies report improvement in symptoms of GSM/VVA and sexual function, high patient satisfaction, and minor adverse events, including treatment-associated pain, swelling, or vaginal discharge.

CONCLUSION

This review demonstrates radiofrequency and laser are efficacious for the treatment of vaginal laxity and/or atrophy. Further research needs to be completed to determine which specific pathologies can be treated, if maintenance treatment is necessary, and long-term safety concerns.

Fractional Microablative CO2 Laser-Related Histological Changes on Vulvar Tissue in Patients With Genitourinary Syndrome of Menopause

BACKGROUND AND OBJECTIVES

Fractional CO₂ laser has been proposed as an effective treatment for the genitourinary syndrome of menopause (GSM). However, the effects of laser treatment on vulvar tissue have never been assessed. We aimed to assess histological changes related to fractional CO₂ laser in vulvar tissue from GSM patients.

STUDY DESIGN/MATERIALS AND METHODS

A single-center observational prospective cohort study was performed enrolling all GSM patients from July 2017 to October 2018. Patients underwent three outpatient vulvovaginal applications of fractional CO₂ laser and vulvar biopsy before and after treatment. Rates of histological changes in vulvar tissue, the difference in means of Vulva Health Index (VuHI), Vaginal Health Index (VHI), Visual Analogue Scale scores for GSM symptoms, and procedure-related pain, and rate of patient's overall satisfaction with treatment were assessed. Univariate comparisons between continuous variables were performed by using the paired t-test (α error = 0.05).

RESULTS

Of 20 enrolled patients, 18 underwent all laser applications, and 15 underwent both vulvar biopsies. 93.3% of patients showed remodeling of vulvar connective tissue; 80% showed improvement in vulvar epithelium trophism and 86.7% showed neovascularization. Differences in means between before and after treatment were significant for VuHI, VHI, and all GSM symptoms. Means ± standard deviation of the degree of pain at each laser application were 4.4 ± 0.9, 3.7 ± 1.6, and 2.9 ± 1.9. The rate of overall satisfaction with the treatment was 72.2%.

CONCLUSIONS

Fractional CO₂ laser leads to a restoration of the normal architecture of vulvar tissue, with significant improvement in GSM-related signs and symptoms, and overall satisfaction with the treatment in most GSM patients. Lasers Surg. Med. © 2020 Wiley Periodicals LLC.

Can pelvic organ prolapse in postmenopausal women be treated with laser therapy?

PURPOSE

This study aims to assess the effectiveness of the non-ablative photothermal erbium laser (Er:YAG laser) for managing anterior and/or posterior vaginal compartment prolapse.

METHODS

A randomized, single-blind, 1:1 trial was performed comparing Er:YAG laser treatment to watchful waiting in postmenopausal women with symptomatic cystocele and/or rectocele stage 2 or 3 who opted to undergo surgery due to bothersome prolapse symptoms. Three Er:YAG laser treatments at monthly intervals were applied for the Er:YAG laser group, while there was no treatment for the watchful-waiting group. The primary outcome was the proportion of patients with stage 0 or 1 following laser treatment, while secondary outcomes included the Pelvic Organ Prolapse Quantification System (POP-Q points), Pelvic Floor Distress Inventory Questionnaire short-form, Pelvic Floor Impact Questionnaire short-form, and Patients Global Impression of Improvement (PGI-I). All outcomes were evaluated at baseline and 4 months post baseline.

RESULTS

Thirty women (15 vs. 15) were eligible to be included. No participants (0%) in either group had POP-Q stage 0 or 1 at 4 months. Moreover, no change was present in the secondary outcomes. In the PGI-I, 2/15 (14%) and 0/15 (0%) participants declared much better/very much better in the laser and watchful-waiting group, respectively.

CONCLUSIONS

The findings of this study do not support use of the intravaginal Er:YAG laser for treatment of the anterior/posterior vaginal wall. Clinical trial identification number: NCT03714607.

Fractional Co2 Laser Treatment of the Vulva and Vagina and the Effect of Postmenopausal Duration on Efficacy

BACKGROUND AND OBJECTIVES

More studies are needed to assess the long-term safety profile and clinical outcomes of lasers and energy-based devices to treat the symptoms associated with vulvovaginal atrophy. This study evaluated a series of three fractional CO₂ laser treatments to the vulva and vagina with a 1-year follow-up in a postmenopausal population.

STUDY DESIGN/MATERIALS AND METHODS

In this prospective, self-controlled, open-label clinical study, 18 postmenopausal females with atrophic vaginitis received 3 monthly treatments to the vulva and vagina with a fractional CO₂ laser system and 1-, 3-, 6-, and 12-month follow-up. Investigators used the Vaginal Health Index (VHI) to assess changes in vaginal elasticity, fluid volume, vaginal pH, epithelial integrity, and moisture. Sexual function at each timepoint was subject-reported, using the validated Female Sexual Function Index (FSFI).

RESULTS

Treatment of the vulva and vagina in postmenopausal women with fractional CO₂ laser resurfacing resulted in statistically significant improvements as compared with baseline at all post-treatment and follow-up intervals to 12 months in VHI and FSFI (P ≤ 0.003 and P ≤ 0.03, respectively). Mean total VHI score increased from a baseline of 11.8-22.8 (93.2% improved) at 6-month follow-up (P = 0.0002) slightly decreasing to 21.4 (81.4% improved) at 12-month follow-up post-treatment (P = 0.0003). Mean FSFI Scores increased from a baseline of 17.9-26.3 (46.9% improvement) at 12-month follow-up post-treatment (P ≤ 0.0048). Cohort analysis revealed restoration of normal or near-normal (23-25) VHI following laser treatment in the recently menopausal (1-3 years) greatly exceeded that of the >3 years postmenopausal population and the difference was statistically significant (P ≤ 0.05). Normal/near-normal VHI at 3-, 6-, and 12-month post-treatment was 88%, 88%, and 63% in the recently postmenopausal cohort, as compared with 30%, 40%, and 10% of the >3 years postmenopausal group (P ≤ 0.05). Patient satisfaction following treatment was rated as high at 94% at 12-month follow-up. Safety findings demonstrated no-to-slight discomfort in the majority of subjects and transient erythema and edema, with no adverse events associated with treatment.

CONCLUSION

Fractional CO₂ laser treatment of the vulva and vagina resulted in statistically significant improvements in VHI and FSFI compared with baseline in postmenopausal population that were sustained to 12-month follow-up. Restoration of normal VHI was observed in a statistically significant greater percentage in the recently postmenopausal cohort (1-3 years) as compared with postmenopausal cohort of >3 years, suggesting that early intervention is correlated with improved outcomes.
