Laser therapy for the restoration of vaginal function

Exploring the role of laser therapy for stress urinary incontinence: a literature review

Stress urinary incontinence (SUI) significantly impacts the quality of life, necessitating innovative treatment options beyond conventional approaches. This comprehensive review aimed to evaluate laser therapy as a promising intervention for SUI management. A systematic search was conducted using the keywords "laser" and "stress urinary incontinence" in the PubMed, Scopus, Web of Science, and Embase databases. The search covers studies from January 1, 2014, to November 30, 2024. A comparative analysis with traditional treatments, such as pelvic floor exercises and medications, underscores the potential advantages and limitations of laser therapy. Clinical studies and research findings are examined to evaluate the efficacy and safety profile of laser therapy, including its short-term success rates and potential complications. Patient experiences and perspectives provide a qualitative dimension, offering insights into the real-world impact and challenges associated with laser therapy for SUI. This review also explores the cost-effectiveness of laser therapy and compares its long-term and short-term effects, positioning it within the broader landscape of SUI management. Future trends and ongoing research are outlined, highlighting the potential integration of laser therapy with multimodal approaches. Recommendations for clinical practice emphasize patient selection criteria and address concerns and expectations, ensuring laser therapy is adopted as a valuable and evidence-based addition to SUI management.

Sexual function after treatment with non-invasive radiofrequency device for improvement of the genitourinary syndrome of menopause: A multi-arm randomized clinical trial

BACKGROUND

Several anatomical and functional changes occur during menopause and lead to female sexual dysfunction (FSD). The use of energy-based devices to improve women's sexual health brings an innovative scenario.

AIM

To evaluate the effect of non-invasive radiofrequency (RF) treatment compared to vaginal estrogen therapy (E) and vaginal moisturizer (M) in postmenopausal women with FSD.

MATERIALS & METHODS

Thirty-two sexually active postmenopausal women aged 45-75 years were enrolled in a single center randomized controlled trial with three intervention arms: non-invasive RF, vaginal estrogen (E), or vaginal moisturizer (M) treatment. Assessments at baseline, and 4 months were conducted using the Female Sexual Function Index (FSFI). The primary outcome of this RCT was an assessment of the effect of RF on FSD compared to that of E and M.

RESULTS

According to the total FSFI score, 100 % of participants in the RF and E arms and 90 % in the M arm had sexual problems at the baseline. The mean age of the participants was 58+/-5.3, 57.9+/-6.3, and 59.6+/-6.0 years in the RF, E, and M arms, respectively (p = 0.741). After 4 months of follow-up, FSD had ameliorated by 146.1 % in the RF arm (improvement of 17.32 points in the total FSFI score), with no significant improvement in the other arms (p = 0.009). We observed improvements in sexual desire (1.32 points in the partial FSFI score), arousal (2.37 points in the partial FSFI score), and orgasm (2.8 points in the partial FSFI score) only in the RF arm (p = 0.004, p < 0.001, and p < 0.001, respectively).

CLINICAL IMPLICATIONS

The use of an energy-based device independently of hormonal therapy to improve female SF is very promising. Our findings may contribute to treatment decisions when there is failure of vaginal estrogen therapy, a need for a combination of treatments, or a patient preference for the use of energy-based devices, in postmenopausal women with FSD.

CONCLUSION

Non-invasive RF treatment for FSD showed superior efficacy compared to vaginal estrogen therapy and vaginal moisturizer after 4 months of follow-up. Further studies with longer follow-up periods are needed to corroborate these findings and evaluate the long-term effects of non-invasive RF therapy on sexual function.

Hyaluronic acid and erbium laser for the treatment of genitourinary syndrome of menopause

OBJECTIVE

This study aimed to evaluate the effect of the vaginal erbium laser (VEL) in association with vaginal hyaluronic acid (HA) in postmenopausal women suffering from genitourinary syndrome of menopause (GSM).

METHODS

One hundred sexually active postmenopausal women were selected and divided into three groups using a block randomization method; 10 women declined to participate. The remaining women received three laser applications at 30-day intervals; 22 women dropped out for personal reasons or protocol violations. Group 1 (n = 25) received VEL treatment (XS Fotona Smooth®; Fotona, Slovenia) alone; Group 2 (n = 22) received daily vaginal HA tablets for 10 days after VEL treatment, followed by a twice a week administration during the follow-up period; and Group 3 (n = 21) received daily HA tablets for 10 days before the first VEL treatment and for 10 days after each laser application, followed by a twice a week administration for the follow-up period. Vaginal dryness and dyspareunia were assessed at the screening visit, before VEL treatment, after 1 and 3 months from the last laser treatment, using the visual analog scale. Data were analyzed using one-way analysis of variance and a linear mixed model for repeated measures. The post-hoc test for the interaction between time and treatment was performed using Bonferroni correction.

RESULTS

A significant (p < 0.001) improvement in both vaginal dryness and superficial dyspareunia was evident, with greater (p < 0.001) improvement in Group 2 and Group 3.

CONCLUSIONS

The results suggest that vaginal HA administration can improve the VEL effects on GSM in postmenopausal women.

Clinical and histomorphometric evaluation of the vagina following treatment with CO2 laser, radiofrequency, and promestriene for genitourinary syndrome of menopause in breast cancer survivors on adjuvant therapy

PURPOSE

To perform clinical and histomorphometric evaluations of the vagina before and after treatment for genitourinary syndrome of menopause with CO2 laser, fractional radiofrequency, and promestriene in breast cancer survivors using adjuvant endocrine therapy.

METHODS

The study included women experiencing moderate to severe genitourinary syndrome of menopause. Following pre- and post-treatment protocols, participants graded their symptoms on a visual analog scale and underwent a gynecological examination to evaluate the Vaginal Health Index and obtain a vaginal biopsy. Subsequently, they were randomized to laser, radiofrequency, and promestriene groups. The energy groups underwent three consecutive monthly outpatient vulvovaginal treatments, while the control group received promestriene treatment for four months, followed by a post-treatment evaluation.

RESULTS

Sixty-two women completed the study protocol (21 laser, 20 radiofrequency, and 21 promestriene). While histological differences (vaginal thickness [p = 0.002] and number of stromal papillae [p = 0.004]) were observed between the pretreatment samples of tamoxifen and anastrozole users, the symptoms did not differ between them. A decrease in symptom intensity (p < 0.05) and an improvement in the Vaginal Health Index (p < 0.001) were observed post-treatment, regardless of the type of adjuvant endocrine therapy used. Most pretreatment vaginal samples did not indicate histological atrophy, and no significant histological differences were observed after treatment. No clinical or histological damage was observed.

CONCLUSION

CO2 laser and radiofrequency therapies could be considered alternative treatments for genitourinary syndrome of menopause in breast cancer survivors receiving adjuvant therapy. These treatments promoted significant improvements comparable to those delivered by promestriene, without histological or clinical tissue damage.

Photobiomodulation in post menopause genitourinary syndrome-Study protocol for a randomized, double-blind, controlled clinical protocol

INTRODUCTION

Genitourinary Syndrome of Menopause (GSM) defines a set of symptoms associated with an estrogen deficit involving alterations in organs genitourinary and that results in several urinary, genital, and sexual alterations. Brazilian women live about a third of their life after menopause, where hormonal changes occur along with clinical manifestations, characterized by vaginal and vulvar dryness, burning sensation, discomfort, vulvovaginal irritation, lack of lubrication, dyspareunia and urinary incontinence. Fractionated photothermolysis and radiofrequency systems, alone or in combination were tested to improve GSM.

OBJECTIVE

The goal of this study is to elaborate a protocol to evaluate the clinical response of patients with symptoms of GSM after the application of photobiomodulation in the vulvar region.

METHOD

In this randomized, double-blind, placebo-controlled study protocol, women over 50 years of age who are in the postmenopausal period (amenorrhea for at least 12 months, with no pathology involved) with one or more symptoms of GSM will be randomly divided into two groups. The treatment group (n = 30) will receive four consecutive applications, weekly, using DMC laser diode (λ = 808 nm), 4J per point, 100mW of power, 1,016W/cm2, 8 sites in the vulvar region, The Placebo Group (n = 30) will be handled as treated, but with the laser turned off. The quality of life will be assessed using female sexual functioning index (FSFI-6), urinary incontinence questionnaire (ICIQ-SF), Quality of life will be analyzed using the female sexual functioning index (FSFI-6). The intensity of menopausal symptoms will be evaluated using a visual analogue scale (VAS), the vulvo vaginal atrophy will be measured by the Vaginal Health Index (VHI). Also, the vaginal temperature will be measured using a thermal camera, the pressure of the pelvic floor force (vaginal dynamometer) and a 1-hour Pad Test will be performed to quantify the urinary loss. With this procedure, we intend to obtain an overall better life quality and diminished symptoms in women with GSM. All assessments will be performed prior to the first irradiation and after the last one.

TRIAL REGISTRATION

This protocol is registered at ClinicalTrials.gov under the number NCT05557799.

Double-blind randomized controlled trial of Er: YAG vaginal laser to treat female stress urinary incontinence

BACKGROUND

Stress urinary incontinence affects approximately 40% of adult females and is often treated surgically. Minimally invasive vaginal laser therapy to treat stress urinary incontinence has become widely available, but the efficacy of this novel therapy is unclear.

OBJECTIVE

This study aimed to determine the efficacy of erbium-doped yttrium aluminum garnet laser as a therapy for stress urinary incontinence.

STUDY DESIGN

This was a double-blind randomized sham-controlled trial with 6-week and 6-month follow-ups at a single tertiary hospital setting with 144 adult female patients with symptomatic stress urinary incontinence. Each participant received 2 vaginal laser therapies 6 weeks apart, with patients randomized to either laser or sham. The primary outcome was patients' subjective reporting of no urinary incontinence at 6 months after treatment on question 3 of the International Consultation on Incontinence Questionnaire-Short Form. The secondary outcomes included objective measures of urine loss with 24-hour pad tests, 3 incontinence symptom questionnaires (Urogenital Distress Inventory-6, Incontinence Impact Questionnaire-7, and International Consultation on Incontinence Questionnaire-Short Form), 1 quality-of-life questionnaire (King's Health Questionnaire), and 1 sexual function questionnaire (Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire).

RESULTS

Of 263 individuals approached, 76 of 144 individuals were randomized to the laser treatment group, and 68 of 144 individuals were randomized to the sham treatment group. There was no difference in the reported cure rate and the primary outcome at 6 months after treatment between the groups (laser treatment group: 0.0136; 95% confidence interval, 0.0006-0.0811; sham treatment group: 0.0000; 95% confidence interval, 0.0000-0.0666). Apart from a statistically significant difference noted at 6 weeks after treatment in 1 of 3 incontinence questionnaires and 3 of 9 domains of the quality-of-life questionnaire, there were no other significant differences in our subjective or objective measures between the 2 groups at 6 weeks and 6 months after treatment.

CONCLUSION

Er: YAG laser was no more effective than sham for curing or improving female stress urinary incontinence at 6 months.

Practical Guidance on the Use of Vaginal Laser Therapy: Focus on Genitourinary Syndrome and Other Symptoms

Genitourinary syndrome of the menopause (GSM) is a chronic, often progressive condition, characterised by symptoms relating to oestrogen deficiency including; vaginal dryness, burning, itching, dyspareunia, dysuria, urinary urgency and recurrent urinary tract infections. GSM affects up to 70% of breast cancer survivors with a tendency to particularly severe symptoms, owing to the effects of iatrogenic menopause and endocrine therapy. Patients and clinicians can be reluctant to replace oestrogen vaginally due to fear of cancer recurrence. Vaginal laser is a novel therapy, which may become a valuable nonhormonal alternative in GSM treatment. There are currently 6 published studies regarding Erbium:YAG laser treatment for GSM, 41 studies regarding CO2 laser treatment for GSM and 28 studies regarding vaginal laser treatment for GSM in breast cancer survivors. Number of participants ranges from 12 to 645. The majority of studies describe a course of 3 treatments, but some report outcomes after 5. Significant improvements were reported in vaginal dryness, burning, dyspareunia, itch, Vaginal Health Index Scores (VHIS), Quality of Life, and FSFI (Female Sexual Function Index). Most studies reported outcomes at short-term follow-up from 30 days to 12 months post-treatment. Few studies report longer-term outcomes with conflicting results. Whilst some studies suggest improvements are sustained up to 24 months, others report a drop-off in symptom improvement at 12-18 months. Patient satisfaction ranged from 52% to 90% and deteriorated with increasing time post-procedure in one study. The findings in this review must be validated in robust randomised sham-controlled trials of adequate power. There remain a number of unanswered questions in terms of which laser medium to use, optimal device settings, ideal interval between treatments, pre-treatment vaginal preparation, as well as safety and efficacy of repeated treatments long term. These issues could be addressed most efficiently with a mandatory registry of vaginal laser procedures.

High-intensity focused ultrasound (HIFU) for the treatment of female urinary incontinence: A retrospective analysis

This study aims to demonstrate the effectiveness of high-intensity focused ultrasound, a noninvasive treatment, for managing urinary incontinence (UI) in women. This is a single-center, retrospective study involving 28 women. Patients, aged between 32 and 65, were included. Patients with insulin-dependent diabetes, neurological disease, active urinary tract infection, undiagnosed vaginal bleeding, who had incontinence surgery, and receiving estrogen therapy were excluded from the study. Incontinence severity was evaluated with the International Incontinence Consultation Questionnaire Short Form (ICIQ-SF). Patients were evaluated before treatment and 6 months after treatment using the ICIQ-SF and the Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Assessment short form. In the analysis of numerical variables independent or paired t test or linear mixed effects models were used. Least square means were used in post hoc comparisons. Mean age of the patients was 45.50 ± 7.59 years. There were 18 (64%) stress urinary incontinence (SUI) and 10 (36%) mixed urinary incontinence (MUI). Six months after treatment, mean ICIQ-SF and Pelvic Organ Prolapse/Urinary Incontinence Short Form Questionnaire scores showed a significant positive change. After the procedure, UI completely disappeared in 43% of the patients. The rate of severe UI decreased from 39% to 8%, and very severe UI decreased from 8% to 0%. Incontinence severity was significantly different in the MUI and SUI groups before and after the procedure. After the procedure, UI completely disappeared in 67% of the patients in the SUI group, while it remained at a mild level in 33%. The decrease in ICIQ-SF score in the SUI group was significantly higher than that in the MUI group. There were no severe adverse events, in 4 patients there was mild vaginal discharge which resolved in 1 week. This study showed that high-intensity focused ultrasound treatment, can be effective and safe even in a single session. Selection and recall biases are potential biases in retrospective studies. Lacking a control group is another limitation. Although advances in technology are very important for medical treatments, their effectiveness and safety need to be proven. Future research in this area with a larger sample size and a prospective design will offer further evidence supporting effectiveness of this treatment model.

The effects of various therapies on vulvovaginal atrophy and quality of life in gynecological cancer patients: a systematic review

PURPOSE

Tumors affecting the female genital tract and their treatments have the potential to induce adverse modifications in vaginal health and impact personal aspects of patient's lives. Vulvovaginal atrophy is one of the morphological changes observed in individuals with a history of gynecological cancer, influenced both by the biological environment of tumors and the main therapeutic modalities employed. Therefore, the purpose of this study was to identify approaches to treat vulvovaginal atrophy while assessing the impact on the emotional and sexual health of women diagnosed with gynecological cancers.

METHODS

To achieve this goal, a systematic review was conducted following the methodological guidelines outlined by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The databases used for literature research were PubMed and Web of Science.

RESULTS

Initially, 886 articles were obtained. After eliminating duplicates and applying inclusion/exclusion criteria, seven articles were selected for analysis. The period of highest publication activity spanned from 2017 to 2020, with the majority conducted in Italy. Five treatment modalities were identified and categorized as vaginal suppository, oral medication, surgical procedure, CO2 laser therapy, and vaginal dilator. Twenty-four outcomes related to vaginal health and 30 outcomes related to overall, sexual, and emotional quality of life were analyzed.

CONCLUSION

In general, all interventions demonstrated the ability to improve vaginal health or, at the very least, the sexual health of patients. Thus, despite limitations, all treatments have the potential to address vulvovaginal atrophy in patients with a history of gynecological cancer.

The Efficacy of CO2 Vaginal Laser in the Treatment of Recurrent, Post-Coital and Interstitial Cystitis: A Multicentric Prospective Study

Background: This multicentric prospective study was carried out at Fondazione Policlinico Universitario Campus Bio Medico and Ospedale di Stato of St. Marino Republic. Between 1 January 2019, and 31 December 2022, all pre- and post-menopausal women diagnosed with recurrent, post-coital, and interstitial cystitis at both centers were included in the study. The main aim of the study was to assess the effectiveness of vaginal CO2 laser treatment, alone or combined with intravesical hyaluronic acid instillations, in managing cystitis symptoms, such as dysuria, pollakiuria, and urgency, across the entire patient cohort. The secondary objective was to investigate the reduction in number of annual cystitis episodes post-treatment. Methods: Each woman underwent three to four sessions of micro-ablative CO2 vaginal laser treatment. A follow-up examination was conducted 12 months after the final laser session (up to December 2023), during which a post-treatment VAS assessment evaluated dysuria, daily pollakiuria, and urgency. The enrolled patients recorded the number of cystitis episodes experienced during the 12-month pre- and post-treatment period. Results: Results indicated the laser's efficacy in reducing the total number of cystitis episodes per year and an improvement in symptoms up to one year post-treatment. Greater efficacy of the CO2 laser treatment, particularly when combined with intravesical hyaluronic acid instillation, was observed in both pre- and post- menopausal women. Conclusions: Fractional CO2 laser therapy represents a safe and efficacious, non-hormonal approach for pre- and post-menopausal women diagnosed with recurrent, post-coital, and interstitial cystitis.

Safety and Efficacy of Erbium: Yttrium-Aluminum-Garnet Laser Treatment in Chinese Women with Mild-to-Moderate Stress Urinary Incontinence

Background: This study aims to evaluate the safety and efficacy of erbium:yttrium-aluminum-garnet (Er:YAG) laser treatment in female patients with mild-to-moderate stress urinary incontinence (SUI). Methods: From July 2018 to June 2020, 72 female patients with mild-to-moderate SUI were enrolled in this study. A baseline assessment was conducted, which included a 1-hour pad test, the validated International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI-SF), postvoid residual (PVR) testing, pelvic organ prolapse quantification (POP-Q) testing, and a cough stress test. All patients underwent four sessions of Er:YAG laser treatment using a smooth mode. A reassessment was performed 6 months after treatment to evaluate the safety and efficacy of the Er:YAG laser. Results: All patients completed four clinic visits, with a 1-month interval, and were followed up for a minimum of 6 months. No severe adverse reactions were observed during the treatment process. The 1-hour pad test revealed a significant reduction in urinary leakage from baseline (6.30 ± 1.06 g) to the 6-month follow-up (2.70 ± 0.96 g, p < 0.001), with 34 of 72 (47.22%) patients achieving negative results. The ICIQ-UI-SF score significantly decreased from baseline to 6 months (10.82 ± 1.38 to 2.96 ± 0.52, p < 0.001). PVR experimental results showed a significant decrease in residual urine volume after treatment (103.72 ± 8.61 mL to 43.86 ± 4.92 mL, p < 0.001). At the 6-month follow-up, hematoxylin and eosin staining results demonstrated that Er:YAG laser treatment significantly facilitated an increase in the thickness of squamous epithelial cells. The efficacy of Er:YAG laser treatment for SUI was 77.78% (56/72). Conclusions: Several objective and subjective assessments confirmed the safety and efficacy of vaginal smooth mode Er:YAG laser treatment for mild-to-moderate SUI during the 6-month follow-up period. Nonablative Er:YAG laser in the smooth mode is a viable treatment option for SUI patients.

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.

Fractional CO2 Laser for Vulvar Tissue Rejuvenation: A Prospective Study

Objective: Aging and changes in hormone levels influence the appearance of the vulva, including the texture, pigmentation, and other manifestations, all of which may largely affect the physical and mental health of women. This study aimed to evaluate the efficacy and safety of fractional carbon dioxide (CO2) laser treatment for vulvar rejuvenation in Chinese women. Background: The limited options currently available for vulvar rejuvenation raise concerns. There is insufficient evidence to determine whether the fractional CO2 laser can safely and effectively rejuvenate the vulvar area for women of various ages and races. Methods: The study included 17 patients (mean age = 36.4 years) treated three times by continuous fractional CO2 laser with an interval of 1 month between each session. The primary outcomes were changes in vulva texture and pigmentation. Treatment was evaluated using images of the patients. Baseline and posttreatment images were collected and evaluated using a scoring system from 0 to 3 to grade the vulvar texture and pigmentation changes. In addition, patients rated their degree of vaginal rejuvenation after the treatment using a scoring system from 0 to 3. Results: Fractional CO2 laser treatment effectively and significantly increased vulvar texture and decreased vulvar pigmentation after three sessions (p < 0.05). Patients also self-reported noticeable improvement. There were no adverse reactions during the treatment and follow-up. Conclusions: Fractional CO2 laser treatment is a safe and effective method for vulvar rejuvenation in women.

The Utility of CO2 Laser Treatment of Pelvic Symptoms in Women with Previous Perineal Trauma during Delivery

This study aimed to examine the impact of fractional CO2 laser treatment of pelvic symptoms in women who have undergone perineal trauma from vaginal delivery. It was a retrospective, monocentric analysis that encompassed all women assessed for pelvic discomfort or signs of vulvovaginal atrophy following vaginal delivery between 2013 and 2018. The severity of symptoms was assessed using the Visual Analogue Scale (VAS). Twenty-seven patients met the inclusion criteria and were sorted into two groups: (1) women who had undergone episiotomies during labor (n = 11); and (2) women who had experienced spontaneous tears during vaginal delivery (n = 16). For women with episiotomies, each treatment and subsequent evaluation consistently showed a significant reduction in dyspareunia intensity. A similar positive trend was observed regarding pain at the introitus (7.5 vs. 6.5 after the first treatment, p = 0.03; 6.5 vs. 3 after the second treatment, p = 0.01; 3 vs. 1 after the third treatment, p = 0.01). Among women experiencing spontaneous perineal tears during delivery, there was a notable decrease in dyspareunia following all treatments (8 vs. 7 after the first treatment, p = 0.01; 8 vs. 4 after the second treatment, p = 0.02; 3 vs. 1 after the third treatment, p = 0.03). The impact of laser treatment did not exhibit significant differences between women who underwent episiotomies and those who experienced spontaneous perineal tears. In conclusion, fractional CO2 laser can be regarded as a non-pharmacological option for managing pelvic floor symptoms in women who encountered perineal trauma during delivery, independently from the nature, spontaneity, or iatrogenesis of the perineal laceration.

Not all lasers are the same: a scoping review evaluating laser therapy for vulvodynia

INTRODUCTION

Lasers are commonly used for treating various vaginal/vulvar conditions. To date, there is to our knowledge no available literature review on the effects of different types of lasers for the treatment of women with vulvodynia, a condition that causes chronic pain in the vulvar area.

OBJECTIVES

We sought to review the literature and summarize the existing published evidence regarding the effects of lasers for the treatment of women with vulvodynia.

METHODS

A scoping review with a systematic search was conducted that included studies investigating the use of laser treatment in women with vulvodynia. The National Heart, Lung, and Blood Institute Study Quality Assessment Tools were used for the quality assessment. The type of laser, effects on pain and function, and participants' perceived improvement as well as adverse events were analyzed.

RESULTS

Eight studies investigating laser therapy were included in the analysis: 1 randomized controlled trial, 5 before-after studies, 1 nonrandomized intervention study, and 1 case report. Several types of laser therapies were identified, ranging from mild noninvasive photobiomodulation to more invasive ablative procedures. Of the 6 studies that included pain outcomes, 3 studies showed statistically significant improvements from baseline to follow-up, and 3 demonstrated a reduction in pain from subjectively interpreted data. Similarly, each of the 2 studies investigating sexual function also reported an improvement (based only on subjective interpretation). Of the 2 studies with a comparison group, neither study was adequately powered to detect between-group differences. Furthermore, 57%-78% of participants reported improvement, with 1 study showing a greater statistically significant improvement in the low-level laser therapy patient group compared to the sham laser group. Outcomes and adverse events varied depending on the type of laser used.

CONCLUSIONS

Although these studies demonstrated some benefits of laser therapy for the treatment of vulvodynia, these findings should be interpreted with caution given the scarcity of the included studies that were robust and sufficiently powered. Future research should focus on conducting well-designed randomized controlled trials to evaluate the efficacy of different types of lasers in the treatment of vulvodynia.

Depth-Resolved Attenuation Mapping of the Vaginal Wall under Prolapse and after Laser Treatment Using Cross-Polarization Optical Coherence Tomography: A Pilot Study

Vaginal wall prolapse is the most common type of pelvic organ prolapse and is mainly associated with collagen bundle changes in the lamina propria. Neodymium (Nd:YAG) laser treatment was used as an innovative, minimally invasive and non-ablative procedure for the treatment of early-stage vaginal wall prolapse. The purpose of this pilot study was to assess connective tissue changes in the vaginal wall under prolapse without treatment and after Nd:YAG laser treatment using cross-polarization optical coherence tomography (CP OCT) with depth-resolved attenuation mapping. A total of 26 freshly excised samples of vaginal wall from 26 patients with age norm (n = 8), stage I-II prolapses without treatment (n = 8) and stage I-II prolapse 1-2 months after Nd:YAG laser treatment (n = 10) were assessed. As a result, for the first time, depth-resolved attenuation maps of the vaginal wall in the B-scan projection in the co- and cross-polarization channels were constructed. Two parameters within the lamina propria were target calculated: the median value and the percentages of high (≥4 mm-1) and low (<4 mm-1) attenuation coefficient values. A significant (p < 0.0001) decrease in the parameters in the case of vaginal wall prolapse compared to the age norm was identified. After laser treatment, a significant (p < 0.0001) increase in the parameters compared to the normal level was also observed. Notably, in the cross-channel, both parameters showed a greater difference between the groups than in the co-channel. Therefore, using the cross-channel achieved more reliable differentiation between the groups. To conclude, attenuation coefficient maps allow visualization and quantification of changes in the condition of the connective tissue of the vaginal wall. In the future, CP OCT could be used for in vivo detection of early-stage vaginal wall prolapse and for monitoring the effectiveness of treatment.

Fractional CO2 laser treatment for women with stress predominant urinary incontinence: a randomized controlled trial

INTRODUCTION AND HYPOTHESIS

To evaluate the efficacy of vaginal CO2 laser in women with stress predominant urinary incontinence (SUI) compared with the sham treatment.

METHODS

A randomized controlled trial with sham treatment was conducted between January 2019 and April 2021. Women with predominant SUI were recruited and randomized into two groups: the CO2 laser group (n = 29) and the sham group (n = 30). The International Consultation on Continence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) was used to evaluate the efficacy at 3 months postoperatively. All participants in both groups were advised to perform pelvic floor muscle training (PFMT) after the intervention.

RESULTS

A total of 59 women were studied. A total of 29 women were included in the CO2 laser group and 30 women were included in the sham group. The baseline scores of the ICIQ-UI SF were similar in both groups. A significant improvement in urinary incontinence scores was found in both groups 3 months after treatment (p < 0.001). However, there were no statistically significant differences between the two groups at 3 months (p = 0.8281). There were no changes in bladder neck descent or levator hiatal area immediately after intervention or 3 months after completion of treatment in either group. Most participants who received the active intervention reported mild vaginal pain during the procedure that resolved spontaneously at the end of treatment.

CONCLUSIONS

Fractional CO2 laser treatment does not provide any benefit over the sham technique in alleviating SUI symptoms. The improvement in SUI symptoms in both groups might be related to PFMT. This study was registered with the Thai Clinical Trial Register (TCTR20190131004).

The Pros and Cons of Hystero-preservation on Pelvic Reconstructive Surgery

In the "boat at the dock" theory, pelvic organ prolapse (POP) may happen when the ropes (uterine supportive ligaments) break and/or the water level drops (pelvic floor muscles). Thus, it causes the boat (uterus and other pelvic organs) to slip from normal position and protrude out of the vagina. Surgical intervention with or without hysterectomy (hystero-preservation) is the most effective treatment for POP. Both hysterectomy and hystero-preservation for POP had a high anatomic and clinical cure rate. There is an increasing trend of hystero-preservation for POP during the past decades. The choices of either hysterectomy or hystero-preservation depend on the surgical factors, psychosocial factors, self-esteem and sexuality factors, and surgeon factors. Pelvic reconstructive surgery, either hysterectomy or hystero-preservation, can be performed via different approaches, including abdominal, laparoscopic, and vaginal routes, with native tissue or with mesh. This review will elucidate their related pros and cons, with further discussion and comparison of hystero-preservation via different routes.

Number of vaginal lactobacilli in postmenopausal women with vaginal atrophy before and after treatment with erbium-YAG laser: a randomized sham-controlled trial

PRIMARY OBJECTIVE

To evaluate the effect of erbium-YAG laser on the number of vaginal lactobacilli in postmenopausal women.

SECONDARY OBJECTIVES

To evaluate the effect of erbium-YAG laser on vaginal atrophy symptoms and vaginal pH in postmenopausal women.

MATERIALS AND METHODS

A total of 44 postmenopausal women who met the inclusion criteria were randomized in the laser group (n = 22) and sham group (n = 22). Vaginal lactobacilli grading, vaginal pH, vaginal atrophy score, and vaginal atrophy symptoms were assessed before and after treatment with erbium-YAG laser for two consecutive times, with a four-week interval; the results were compared with the effects of the sham procedure. Any adverse events after the treatment were recorded.

RESULTS

A total of 44 women were included, and five were lost to follow-up. Compared with sham procedure, vaginal lactobacilli grading improved in the laser group (5/20 in the laser group and 1/19 in the sham group). However, the improvement did not reach statistical significance (adjusted odds ratio = 5.32, 95% CI = 0.5-56.21). Vaginal atrophy symptoms measured by the visual analog scale (VAS) and vaginal pH were improved in both groups without a statistically significant difference between the two groups. Vaginal "dryness" VAS and vaginal atrophy score after treatment were significantly lowered in the laser group compared with the sham group.

CONCLUSIONS

This study showed an improvement in vaginal lactobacilli grading after vaginal laser treatment. However, the difference in vaginal lactobacilli grading after treatment in both groups was not statistically significant.

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.

A study of the objective benefits and safety of Er-YAG laser in the treatment of genitourinary syndrome of menopause

The aim of this study is to evaluate changes in vaginal pH and epithelium maturation after erbium-doped yttrium aluminum garnet (Er-YAG) laser treatment, and to assess its safety and efficacy on the symptoms of genitourinary syndrome of menopause (GSM). This was a retrospective study conducted between November 2019 and April 2022 and included 32 women diagnosed with GSM who had not benefitted from lubrication treatment and could not or would not use estrogen. Patients received three sessions of Er- YAG laser. All patient data before and after treatment were obtained from computer records. Vaginal maturation index (VMI), maturation value (MV) and vaginal pH values of the patients before and after laser treatment were compared. We also evaluated post-procedural complications and symptoms. Mean age was 59.72 ± 5.66 years. After laser therapy, there was a significant decrease in vaginal pH (p < 0.001) and the proportion of parabasal cells in VMI (p < 0.001), while there was a significant increase in MV (p < 0.001) and the proportion of superficial cells in VMI (p < 0.001). In 84.4% of the patients, GSM-related symptoms regressed completely or decreased to a tolerable level. Patients in which symptoms disappeared completely had significantly lower mean age (p = 0.002) and duration of menopause (p = 0.009). The laser procedure resulted in complications including mucosal injury in 5 (15.6%) patients (all recovered spontaneously) and vaginal burning sensation in 2 (6.3%) patients. Vaginal Er-YAG laser treatment may be a safe and effective alternative treatment method in a population of women with GSM who do not want to or cannot use estrogen therapy.

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.

Sequential treatment in vulvovaginal atrophy

Vulvovaginal atrophy (VVA) is a chronic and progressive disease that affects sexuality and quality of life. VVA is preventable and treatable, but requires long-term and often sequential treatment. Sequential treatment consists of designing a strategy that uses one or more medications for a long enough time to achieve the desired benefits with minimal risk and maximum adherence. Currently available therapeutic options consist of topical over-the-counter products (including non-hormonal lubricants and moisturizers applied to the vagina), systemic hormone therapy and estrogens, and prescribed vaginal dehydroepiandrosterone (DHEA). In addition, we have a selective estrogen receptor modulator, ospemifene, and new energy-based treatments (laser and radiofrequency). There are clear differences between the treatments both in the mechanism of action and in the efficacy. Compliance is very low, and patients complain about the use of the vaginal route, often due to its low efficacy, or express fear of the long-term use of estrogens or the price of the treatments. We believe that, as a first option, and for physiological, preventive and efficacy reasons, we should consider the prescription of treatments that work on estrogen receptors. As a second option, there are vaginal moisturizers, which are effective on symptoms but do not prevent or improve conditions. Finally, techniques using heat, which although each time represent a clearer alternative, but on the other hand are the cost and the long-term safety data, give us a third option. Of course, we consider that vulvar moisturizers and lubricants can be used at any time.

Superficial dyspareunia treatment with hyperstacking of erbium:yttrium-aluminum-garnet SMOOTH laser: a short-term, pilot study in breast cancer survivors

OBJECTIVE

This prospective pilot study aimed to evaluate the effects of a modified vaginal erbium laser (VEL) protocol, using the hyperstack mode on the vaginal vestibulum and introitus to treat superficial dyspareunia in postmenopausal breast cancer survivors suffering from the genitourinary syndrome of menopause.

METHODS

In this pilot, prospective, randomized study, two groups of postmenopausal women suffering from superficial dyspareunia were included: 34 women (VEL group) were treated with erbium laser crystal yttrium-aluminum-garnet (XS Fotona SMOOTH; Fotona, Ljubljana, Slovenia) with a wavelength of 2,940 nm; for the other 34 (hyperstack group), a modified second step of the VEL protocol for the treatment of vestibulum and introitus was used, with hyperstacked (repeating a number of) subablative, long pulses with very low fluences. For each group, three laser applications at 30-day intervals were performed. Symptoms were assessed before, after each application, and after 1 and 3 months from the last laser application, using the visual analog scale score for superficial dyspareunia.

RESULTS

Superficial dyspareunia improved in both groups over time (P < 0.001), regardless of age and years since menopause status. The reduction in visual analog scale score after the third laser application was 58% in VEL versus 73.5% in hyperstack. The hyperstack group, since the first laser application, showed a greater (P < 0.001) and persistent improvement of superficial dyspareunia.

CONCLUSIONS

The hyperstack treatment of the introitus and vestibulum in breast cancer survivors leads to a more significant improvement in superficial dyspareunia than the VEL alone.

Micro-Focused Ultrasound Therapy in Patients with Urogenital Atrophy and Vaginal Laxity

Vaginal laxity (VL) and genitourinary syndromes of menopause (GSM) create physical, psychological, and functional problem for women and their partners. We aimed to evaluate the efficacy and safety of micro-focused ultrasound (MFU) therapy performed twice in the vaginal canal in a patients with VL and GSM. A total of 20 women with GSM and VL were treated with MFU Ultravera by Hironic. The treatment course consisted of two vaginal applications of MFU at an interval of 6 weeks. The clinical effects of the protocol were evaluated using the Vaginal Laxity Questionnaire (VLQ), the Vaginal Health Index (VHI), and the Female Sexual Function Index (FSFI). The overall values of the vaginal laxity evaluation for the total subject population showed a statistically significant improvement between the baseline and the findings at 3 and 6 months after treatment. The effect of therapy was consistent across all domains of FSFI. It peaked at the 6 week follow-up visit (from 26.5 to 32) and plateaued at 12 weeks and 6 months. There was a significant VHI improvement over time, with the greatest and most significant change between the study entry and 21 days after treatment; the VHI score leveled off up to 3 months after the procedures. MFU therapy, performed twice in the vaginal canal, showed promising efficacy and safety profiles, meriting further investigation.

Vaginal laser therapy for gynecologic conditions: re-examining the controversy and where do we go from here

Despite significant controversy, vaginal laser therapy continues to be used for treatment of many gynecologic and pelvic conditions including vaginal atrophy, vaginal dryness, dyspareunia, urinary incontinence and pelvic pain. This commentary reviews the controversy surrounding vaginal laser therapy and summarizes the important distinction between ablative and non-ablative vaginal lasers. While much research is still needed, the article describes what is important for healthcare professionals to know before making the decision to integrate this technology into their clinical practice.

Efficacy of intradermal hyaluronic acid plus polynucleotides in vulvovaginal atrophy: a pilot study

OBJECTIVE

This study aimed to evaluate the safety and efficacy of vulvovaginal intradermal injections of polynucleotides (PN) combined with hyaluronic acid (HA) in postmenopausal women affected by vulvovaginal atrophy (VVA).

MATERIALS AND METHODS

Postmenopausal women affected by VVA were treated with vulvar and vaginal intradermal injections of one prefilled syringe of 2 ml PN/HA every 2 weeks for four sessions. Patients were evaluated at T0 (baseline), T1 (after session 4) and T2 (1 month after session 4). Evaluation of the treatment was assessed by three international validated questionnaires: Vaginal Health Index (VHI), Vulvar Health Index (VuHI) and Female Sexual Function Index (FSFI). The Wilcoxon matched-paired signed-rank test was used to compare the differences in VHI, VuHI, FSFI and FSFI domains within the groups. Statistical significance was set at p < 0.05.

RESULTS

Fifty patients were included in the study (mean age 59.9 ± 7.6 years). Overall, the VHI, VuHI and FSFI reported statistically significant differences between baseline and T1 (p < 0.001) and between baseline and T2 (p < 0.001). All FSFI domains registered a statistically significant increase between baseline and T2 (p < 0.001). No complications or side effects were observed.

CONCLUSIONS

Vulvovaginal intradermal injection of PN/HA is a safe, effective treatment, is not expensive and is a reproducible procedure in postmenopausal women with VVA.

Short-term effects of an erbium/neodymium laser combination in superficial dyspareunia: a pilot study

OBJECTIVE

This prospective pilot study aimed to evaluate the effects of associating a neodymium:yttrium-aluminum-garnet (Nd:YAG) laser with a vaginal erbium laser (VEL), as a non-ablative photothermal therapy for superficial dyspareunia in postmenopausal women (PMW) suffering from genitourinary syndrome of menopause (GSM).

METHODS

Two groups of sexually active PMW reporting superficial dyspareunia were selected: one (15 patients, VEL) was treated using an erbium:yttrium-aluminum-garnet laser crystal (XS Fotona SMOOTH; Fotona, Ljubljana, Slovenia) with a wavelength of 2940 nm; in the other group (15 patients, VEL + Nd:YAG) this treatment was followed by Nd:YAG laser (Fotona SP Dynamis, PIANO mode) treatment. Treatment consisted of three laser applications at 30-day intervals. Symptoms were assessed before, after each laser application and after 1 and 3 months from the end of the treatment, using the subjective visual analog scale (VAS) for superficial dyspareunia.

RESULTS

Both groups showed a rapid and significant improvement of superficial dyspareunia over time (p < 0.001) independently from age and years since menopause. The VEL + Nd:YAG group showed a greater improvement of superficial dyspareunia (p < 0.001); this difference was evident since the first treatment and remained stable over time.

CONCLUSIONS

The addition of Nd:YAG to VEL may induce greater improvement in superficial dyspareunia in PMW with GSM.

Changes in sexual function and vaginal topography using transperineal ultrasound after vaginal laser treatment for women with stress urinary incontinence

We aim to assess the changes in sexual function and vaginal topography using 3-D transperineal ultrasound in stress-incontinent women treated with Er:YAG vaginal laser. Two hundred and twenty women with stress urinary incontinence (SUI) treated with Er:YAG laser were recruited. Assessment before and 6 months after the treatment included vaginal topography using 3-D transperineal ultrasound and sexual function using female sexual function index questionnaire (FSFI). A total of 50 women with complete data showed that the symptomatic improvement was noted in 37 (74%) women. After Er:YAG vaginal laser treatment, significantly decreased width and cross-sectional area in proximal, middle, and distal vagina were found in women with SUI. Nearly all of the domains of FSFI improved significantly after the vaginal laser treatment, except sexual desire. In conclusion, 3-D transperineal ultrasound can be used to conduct vaginal topography. After Er:YAG vaginal laser treatment, the anatomical changes of vaginal shrinkage and the improvement of female sexual function were both noted. The favorable outcome of sexual function partly related to the tightening of vagina, as evidenced by the measurements of the 3-D transperineal ultrasound.

"Modified Schirmer Test" as an Objective Measurement for Vaginal Dryness: A Prospective Cohort Study

None of the currently available parameters allow for a direct and objective measurement of vaginal moisture. We used a calibrated filter paper strip as a measurement tool for the quantification of vaginal fluid, in a similar manner as the ophthalmic “Schirmer test” (used for eye moisture measurement). The study aimed to evaluate the validity of this new, objective tool, to measure vaginal moisture. We compared vaginal moisture measurements using the “modified Schirmer test” in symptomatic women with genitourinary syndrome of menopause to those of women without vaginal dryness. The mean “modified Schirmer test” measurement in the control group was 21.7 mm compared to 3.3 mm in the study group, yielding a statistically significant difference (p < 0.001). Strong correlations were found between “modified Schirmer test” measurements and pH (correlation coefficient −0.714), Vaginal Health Index [VHI (0.775)], and Visual Analogue Score (VAS) of dryness during intercourse (−0.821). Our findings suggest that the “modified Schirmer test” can be used as an objective measurement for the assessment of vaginal fluid level. This test may also prove useful for evaluation of non-hormonal treatments aimed to treat vaginal dryness.

Comparison of urethral sling surgery and non-ablative vaginal Erbium:YAG laser treatment in 327 patients with stress urinary incontinence: a case-matching analysis

Stress urinary incontinence (SUI) occurs when abdominal pressure, such as from coughing or sneezing, causes urine leakage. We retrospectively compared tension-free vaginal tape (TVT) and non-ablative vaginal Erbium:YAG laser treatment (VEL) by propensity score (PS) analysis in women with SUI. No PS analysis studies have investigated urethral sling surgery using polypropylene TVT and VEL for SUI. Data from patients aged 35-50 years who were treated for SUI and registered at several institutions were selected. Patients with medical records covering 1 year for the 1-h pad test, who completed the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) and the Overactive Bladder Symptom Score (OABSS), were included. We analyzed 102, 113, and 112 patients in the TVT, VEL, and control groups, respectively. Compared with the control group, the TVT and VEL groups exhibited significant improvement in the 1-h pad test and ICIQ-SF. In the PS analysis, the TVT and VEL groups similarly improved in the 1-h pad test and ICIQ-SF. As for the OABSS, the VEL group showed significantly greater improvement than the TVT group. In the odds ratio analysis for the 1-h pad test, no differences in any of the parameters were observed between TVT and VEL. VEL may be considered an alternative to TVT for SUI treatment.

Efficacy evaluation of Lattice Carbon Dioxide Laser Therapy in the treatment of postmenopausal patients with mild to moderate stress urinary incontinence

Objectives

To investigate the efficacy and postoperative complications of lattice carbon dioxide laser in the treatment of postmenopausal patients with mild to moderate stress urinary incontinence.

Methods

A total of 30 postmenopausal female patients with mild to moderate stress urinary incontinence, recruited from the Affiliated Hospital of Hebei University from September to November 2019, were selected as the study subjects and treated with lattice carbon dioxide laser therapy. Treatment was given at intervals of one month. The degree of urinary incontinence, the urinary incontinence questionnaire (ICI-Q-SF) score, and the urinary incontinence quality of life scale (I-QOL)) Score, surgical satisfaction, one hour pad test and postoperative complications before treatment and after each treatment of all patients were respectively recorded and compared.

Results

Compared with those before treatment, the grade of urinary incontinence and ICI-Q-SF scores of these 30 patients after each treatment were lower, and their I-QOL scores were higher. The difference of one hour urine pad test was statistically significant (P<0.05), but the follow-up data of three months after the third treatment was close to that of one month after the first treatment. The satisfaction rate of these 30 patients was 76.67% (23/30). After treatment, only one patient presented vaginal itching discomfort on the first day after surgery and the symptoms disappeared three days later. No obvious complications occurred in the other 29 patients.

Conclusion

The treatment of mild and moderate postmenopausal patients with stress urinary incontinence with lattice carbon dioxide laser can effectively reduce the incidence of incontinence and improve the quality of life.

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.

Low-Level Laser Therapy: Potential and Complications

Introduction: Laser therapy has attracted experts' attention in medical sciences. Many benefits of laser therapy are presented besides some complications. In the present study, it is tried to present a new perspective of laser therapy in the various fields of medicine. Methods: Laser therapy-related articles which are combined with regenerative medicine, cosmetic, dentistry, neurodegenerative diseases, kidney, bone fracture, and vaginal function in the English language were searched through the google scholar search engine in the range of 2000-2021. After title screening, the abstracts were evaluated to access the full texts. Results: Basic concepts and various kinds of lasers which are applied in medicine were explained. Applications of laser therapy in various fields of medicine such as pain reduction, wound healing, regenerative medicine, dentistry, and several other body organs were highlighted and some complications were pointed. Conclusion: High potential of laser therapy for application in medicine implies a reconsideration of the laser properties and also styles of laser applications to improve the treatment and prevention of its side effects.

Microablative Erbium: YAG Laser Therapy for Vulvodynia - A Report on Efficacy, Safety, and Treatment Satisfaction

Introduction

Treatment for vulvodynia is challenging and a multidisciplinary approach is recommended.

Aim

To examine the effectiveness, safety and treatment satisfaction of vulvovaginal microablative laser treatment for vulvodynia.

Methods

Case study of women who received laser treatment as part of a multidisciplinary treatment program for vulvodynia. Subjective improvement was compared to a retrospective cohort of women treated for vulvodynia without LASER therapy. LASER treatment was offered to women with vulvodynia presenting to a gynecologic pain clinic of a tertiary university hospital. LASER treatments were performed with a microablative 2,940 nm Er:YAG LASER and potentially repeated after 1 month.

Main outcome measures

Change in local vulvar pain was assessed with cotton-swab tests and rated on a numeric rating scale (NRS). Treatment discomfort and short-term adverse events were recorded. The Freiburg Index of Patient Satisfaction was used to assess treatment satisfaction. Subjective symptom improvement was assessed with the Patient Global Impression of Improvement questionnaire.

Results

35 women received at least 1 laser treatment, with overall mild treatment adverse effects (mean pain NRS 2.4 ± 1.9) and good treatment satisfaction (mean total score of 27.6 ±5.1; potential range 8–32). One month after last LASER treatment the pain NRS on vulvar cotton swab test improved from 6.1 ± 2.6 at baseline to 3.1 ± 2.6 (P < .001), and 74% of women (n = 26) reported symptom improvement. At 9–12 months follow-up 66% reported ongoing symptom improvement, with no significant difference to the control group of 32 women.

Conclusion

Microablative Er:YAG vulvovaginal LASER therapy appears safe and well accepted among vulvodynia patients, but there was no significant difference in symptom improvement compared to a control group.

Stress urinary incontinence in females. Diagnosis and treatment modalities – past, present and the future

Introduction:

Stress urinary incontinence (SUI) can be defined as involuntary and unintentional loss of urine through the urethra when vesical pressure exceeds the urethral sphincter pressure during instances of coughing, sneezing or physical exercise. Stress urinary incontinence is the most common form of incontinence in females with an estimated prevalence of 4.5–53% in adult women with urinary incontinence. Yet despite its distressing nature and a negative impact on quality of life, very few women present with their symptoms to a urologist.

Materials and methods:

A literature search of the MEDLINE, Cochrane Library, Embase, NLH, ClinicalTrials.gov and Google Scholar databases was done up to November 2020, using terms related to SUI, medical therapy, surgical therapy and treatment options. The search terms included female stress urinary incontinence, mid-urethral sling, tension-free vaginal tape and trans obturator tape. The search included original articles, reviews and meta-analyses.

Conclusion:

Current guidelines for the management of stress urinary incontinence propose a step-ladder pattern, based on treatment invasiveness starting from conservative therapies, then drugs followed by minimally invasive procedures and culminating in invasive surgeries. The surgical approach is to be considered only after conservative therapies fail. The recent advances in the treatment of stress urinary incontinence have brought to light newer modalities and newer technologies that can be utilized which include laser therapy, stem cell therapy, intravesical balloon and others that show a lot of promise. This paper provides an in-depth analysis and reviews the literature on the current modalities and the future prospects of female stress urinary incontinence.

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.

Non-invasive treatment of vulvovaginal atrophy in menopause with CO2 laser

Genitourinary syndrome of menopause (GSM) may affect up to 90% of menopausal women, including vulvovaginal atrophy (VVA), burning, pain, bleeding, irritation, dyspareunia, anorgasmia, and urinary symptoms. Vaginal symptoms from lack of estrogens can have a significant impact on the sexual health and quality of life (QoL) in as many as 50% of postmenopausal women. Several therapeutic alternatives, both hormonal and non- hormonal, have been proposed. Microablative CO<inf>2</inf> laser is one of the three non-surgical energy-based therapies, with Erbium:YAG laser and temperature-controlled radiofrequency (RF). Microablative CO<inf>2</inf> laser induces morphological changes in vaginal tissues and results of several clinical trials suggest that this type of laser improves symptoms of GSM. Moreover, this treatment seems to be safe. Given the increasingly widespread use of laser CO<inf>2</inf> as a non-hormonal alternative treatment for GSM, the authors reviewed the current published literature evaluating this therapy, to compare efficacy and safety of different protocols.

The efficacy of erbium-doped yttrium aluminum garnet (Er:YAG) laser in the treatment of decreased sexual sensation: a randomized, placebo-controlled trial

Vaginal laxity, a common cause of decreased sexual sensation, is a common problem affecting the quality of life of women worldwide. Recently, lasers and energy-based devices (EBDs) have been applied in the treatment of this condition. The aim of this study was to compare the efficacy and safety of Er:YAG laser and placebo in treating decreased sexual sensation in Asians. Forty-two patients with decreased sexual sensation were randomized into 2 groups: intervention (laser treatment) and control (placebo treatment). Both groups received two treatments, at 1-month interval. Subjective and objective evaluations were done at baseline, 1-, 3-, and 6-month follow-ups. Pain score and adverse effects were also recorded. In the laser group, there was significant improvement in the patients' vaginal tightness satisfaction at 1- and 3-month follow-ups (P = 0.002 and 0.004) and also in the patients' overall satisfaction at 1- and 3-month follow-ups (P = 0.003 and 0.001). Pelvic floor muscle contraction was significantly better in the laser group after the first treatment (P = 0.043). No serious adverse effects were noted. Er:YAG laser provides improvement of sexual sensation for an average of 3 months following treatment. Mild and transient adverse effects such as leukorrhea, dryness, dysuria, vaginal itching, and spot bleeding were noted in the laser group, and these were not significantly different from the control group.

Modern management of genitourinary syndrome of menopause

The genitourinary syndrome of menopause (GSM) is the accepted term used to describe the broad spectrum of genitourinary tract symptoms and signs caused by the loss of endogenous sex steroids that occurs at the time of and after the menopause. Global improvements in healthcare have resulted in an ageing population. Today, women are spending 40% of their lives in the postmenopausal state, and with 50–70% of postmenopausal women reporting symptomatic GSM, safe and efficacious treatments are needed for this troublesome condition. This article reviews current evidence for non-pharmacological and pharmacological treatments with a focus on novel and minimally invasive procedures such as energy-based devices (CO₂ laser, YAG laser), hyaluronic acid, dehydroepiandrosterone, and selective oestrogen receptor modulators.

A randomized controlled study of vaginal fractional CO2 laser therapy for female sexual dysfunction

The purpose of this study is to evaluate the efficacy and safety of vaginal fractional CO₂ laser therapy for female sexual dysfunction (FSD). A total of 84 women at high risk of sexual dysfunction were randomly divided into two groups. Women in the laser group received vaginal fractional CO₂ laser therapy. Others in the Kegel group were advised to participate in Kegel exercise training. Sexual distress and sexual function were evaluated by using the Female Sexual Distress Scale-Revised (FSDS-R) and the Chinese version Female Sexual Function Index (CVFSFI), respectively. Adverse events were recorded during the 12-month follow-up. At the end of the 6th and 12th months, the lubrication scores of the CVFSFI in the laser group (4.55±0.05, 4.58±0.09) were significantly higher than those in the Kegel group (4.19±0.15, 4.20±0.14) (P<0.05). The satisfaction scores in the laser group (4.43±0.08) were higher than those in the Kegel group (4.20±0.16) at the end of the 6th month (P<0.05). The self-contrast test in the laser group showed significant improvement in lubrication, pain, satisfaction and total scores after CO₂ laser therapy (p<0.05). These improvements were maintained for 1 year. The improvement of FSDS-R in the laser group (10.0±0.2) was more evident than in the Kegel group (11.1±0.4) at the end of the 12th month. There were no major adverse events reported during laser therapy. Vaginal fractional CO₂ laser therapy can effectively improve sexual function without any serious adverse events. It might be an effective and relatively safe treatment option for improving vaginal mucosa status in sexually active women with sexual dysfunction.

Energy-Based Devices for Functional Vaginal Problems: Issues and Answers

Abstract

Vaginal rejuvenation is a marketing term that encompasses surgical and medical treatments for functional vaginal/vulvar problems including but not limited to genitourinary syndrome of menopause (GSM), sexual dysfunction, vaginal laxity, and stress urinary incontinence (SUI) and for esthetic concerns including dissatisfaction with vulvovaginal appearance. Multiple treatment options have become available for indications of functional vaginal problems. Noninvasive management options including the use of more novel treatments such as energy-based devices have gained interest. Previously, studies regarding the efficacy and safety of the energy-based devices for functional vaginal problems were mostly limited to cohort studies without sham treatment, control groups, randomization, or double blinding. As a result of this insufficient data in 2018, the FDA released a statement of warning against the use of energy-based devices in the treatment of functional vaginal problems or vaginal cosmetic procedures (Https://Www.Fda.Gov/Medical-Devices/Safety-Communications/Fda-Warns-Against-Use-Energy-Based-Devices-Perform-Vaginal-Rejuvenation-or-Vaginal-Cosmetic. 1–4, 2018).

Purpose of Review

This article reviews the most current treatment modalities in the realm of vaginal rejuvenation therapy with an emphasis on the efficacy and safety of the energy-based devices.

Recent Findings

In the most recent literature, there have been studies with improvements in study design that support the efficacy and the short-term safety of the energy-based devices.

Summary

More recent studies with improved study design evidence that the use of energy-based devices results in improvements in functional vaginal problems and that serious adverse events appear to be rare. The availability of these devices as treatment options for functional vaginal problems has the potential to impact patient by improving their symptoms and quality of life. Caution still remains however regarding their safety following a longer period of time after their use.

[Vaginal LASER therapy for genito-urinary disorders: A systematic review and statement from the Committee for Female Urology and Pelviperineology of the French Association of Urology]

INTRODUCTION

Vaginal LASER therapy is increasingly used in the field of urogynecology, but several points remain unclear. Our goal was to produce a systematic review of available evidence and provide a critical appraisal of available data.

METHODS

A systematic review until march 2020 was conducted using PubMed/MEDLINE, Cochrane and Embase databases. All studies about vaginal LASER use in the field of urogynecology were included.

RESULTS

Forty studies have been included (8 for genitourinary syndrome of menopause, 19 for stress urinary incontinence, 3 for overactive bladder, 7 for urogenital prolapse, 3 for other indications). Data were heterogeneous, and level of evidence was weak or very weak. Few studies were comparative, and only 3 were randomized). Mild improvement of symptoms and quality of life and limited satisfaction were seen for genitourinary syndrome, stress urinary incontinence, overactive bladder and prolapse. Few adverse events were reported. However, major methodological biases were noted regarding efficacy and safety evaluation. No long-term results were available.

CONCLUSIONS

While Vaginal LASER therapy seem to provide encouraging results, the level of evidence supporting its use was weak, especially regarding long-term outcomes. Studies of better quality are warranted before any recommendation can be made. Current use should be limited to clinical research.

Repopulation of decellularised articular cartilage by laser-based matrix engraving

BACKGROUND

In spite of advances in the treatment of cartilage defects using cell and scaffold-based therapeutic strategies, the long-term outcome is still not satisfying since clinical scores decline years after treatment. Scaffold materials currently used in clinical settings have shown limitations in providing suitable biomechanical properties and an authentic and protective environment for regenerative cells. To tackle this problem, we developed a scaffold material based on decellularised human articular cartilage.

METHODS

Human articular cartilage matrix was engraved using a CO₂ laser and treated for decellularisation and glycosaminoglycan removal. Characterisation of the resulting scaffold was performed via mechanical testing, DNA and GAG quantification and in vitro cultivation with adipose-derived stromal cells (ASC). Cell vitality, adhesion and chondrogenic differentiation were assessed. An ectopic, unloaded mouse model was used for the assessment of the in vivo performance of the scaffold in combination with ASC and human as well as bovine chondrocytes. The novel scaffold was compared to a commercial collagen type I/III scaffold.

FINDINGS

Crossed line engravings of the matrix allowed for a most regular and ubiquitous distribution of cells and chemical as well as enzymatic matrix treatment was performed to increase cell adhesion. The biomechanical characteristics of this novel scaffold that we term CartiScaff were found to be superior to those of commercially available materials. Neo-tissue was integrated excellently into the scaffold matrix and new collagen fibres were guided by the laser incisions towards a vertical alignment, a typical feature of native cartilage important for nutrition and biomechanics. In an ectopic, unloaded in vivo model, chondrocytes and mesenchymal stromal cells differentiated within the incisions despite the lack of growth factors and load, indicating a strong chondrogenic microenvironment within the scaffold incisions. Cells, most noticeably bone marrow-derived cells, were able to repopulate the empty chondrocyte lacunae inside the scaffold matrix.

INTERPRETATION

Due to the better load-bearing, its chondrogenic effect and the ability to guide matrix-deposition, CartiScaff is a promising biomaterial to accelerate rehabilitation and to improve long term clinical success of cartilage defect treatment.
