This is a prospective, multi-centre, double blinded, randomized controlled trial, which will be conducted under a common protocol.
The aim of this study is to evaluate the efficacy of vaginal laser for treatment of GSM (Genitourinary Syndrome of Menopause) compared to the sham procedure in postmenopausal women.
The study population is female subjects > 18 years old with symptoms of genitourinary syndrome of menopause (GSM) who have not menstruated for at least 5 years.
The clinical data will be analysed by comparing post-treatment data with the baseline data (clinical history, compliance with selection, inclusion and exclusion requirements, assessment of the muscle and pH, and questionnaires). The follow-up is for 6 weeks after the procedure, a physical examination will be passed again to assess whether the effects on the tissue are maintained once the treatment is finished (coloration, hydration, and mobility of the tissue). Two biopsies will be taken, once at the beginning of treatment and another at the end.
The symptoms of SGM worsen as the age of the subject advances, which is why a treatment is required that improves the symptoms in the long term and maintains them once the treatment is finished. For this reason, the objective is to carry out a randomized control study with a new K-Laser Cube device that minimizes the possible risks of conventional vaginal laser therapy.
The hypothesis is that women who will undergo vaginal K-Laser treatment will report an improvement not only in SGM, but also in pelvic floor dysfunctions. The objective in this pilot study will be to evaluate the effects of K-laser treatment on pelvic floor dysfunctions using validated and commonly used questionnaires.
Changes in vaginal pH measured by FSFI (Female Sexual Function Index) questionnaire and changes in the deep musculature with the PERFECT protocol and the OXFORD scale will be the primary endpoints of the study. The secondary endpoints include quality of life changes with the SF-12 (Short Form) health questionnaire and Cervantes Scale, CPPQ-Mohedo (Chronic Pelvic Pain Floor) questionnaire, PFDI-20 (Pelvic Floor Distress Inventory) questionnaire and the Menopause Rating Scale (MSR).

| Change from Baseline in Vaginal pH | During the physical examination a sample of the mucosa will be extracted to check the acidity of the pH. This is a marker of the health of the vaginal flora and abnormalities in pH values will be determined by hormonal imbalances of oestrogens. A pH> 4.5 refers to a decrease in local vaginal defenses which predisposes to infections or inflammatory processes. The pH analysis is a valid tool to diagnose menopause equivalent to an analysis of the levels of the follicle-stimulating molecule (FSH) non-invasive and inexpensive. | The evaluation will be done at baseline before treatment and 6 weeks post treatment |
| Change from Baseline in the deep musculature with the PERFECT protocol | Digital evaluation is essential during the examination of the pelvic floor muscles. For this, digital palpation and a pressure gauge will be used. Digital assessment is performed by inserting the index and middle fingers into the distal 3 centimetres of the vagina in a frontal plane. The PERFECT protocol is described as an acronym for evaluating the main components of pelvic floor muscle contractility. The components are: P (power, score muscle strength according to the OXFORD scale), E (endurance, time the maximum contraction is maintained without loss of strength), R (repetitions, number of contractions with intervals of 4 to 10 seconds), F (number of fast contractions followed after a rest of 1 minute), ECT (every contraction timed: each contraction measured) that consists in evaluating each contraction before the beginning of the treatment, which allows individualizing the program. | The evaluation will be done at baseline before treatment and 6 weeks post treatment |
| Analysis of the impact on QoL (Quality of life) with the FSFI (Female Sexual Function Index) questionnaire. | FSFI questionnaire assesses sexual function in women with pelvic floor dysfunction. It consists of 6 domains and 19 items (Cronbach's alpha coefficient =0.85). The maximum score is 36.0 (high level of sexual functional) and minimum score is 2.0 (low level of sexual functional). The domains are: desire (2 items), arousal (4 items), lubrication (4 items), orgasm (3 items), satisfaction (3 items), pain (3 items). |

| Analysis of the impact on QoL (Quality of life) with the SF-12 (Short Form) health questionnaire. | This questionnaire is the reduced Spanish version of the SF-36 general health questionnaire, which has 35 items divided into 8 dimensions (physical function, physical role, emotional role, social function, mental health, general health, body pain and vitality). The SF-12 questionnaire has 12 items distributed in 2 health components: physical (CSF) with a Cronbach's alpha coefficient of 0.85 and mental (CSM) with a Cronbach's alpha coefficient of 0.78. It is one of the most widely used generic instruments for evaluating health-related quality of life. |

| Analysis of the impact on QoL (Quality of life) with Cervantes Scale | The Cervantes scale is a questionnaire to measure health-related quality of life. It is a tool specifically designed and validated for menopause in Spanish women, original in Spanish and adapted to our environment. The definitive scale consists of 31 items and 2 dimensions: menopause and health. 15 items are related to vasomotor symptomatology, health and aging; 4 items with sexuality; 3 items with the couple relationship and 9 items with psychic domain. The global Cronbach's alpha coefficient is 0.909 and that of the different subscales between 0.79 and 0.85. It is a short scale and easy and quick to apply, approximately 7 minutes. The bases fluctuate between 0 (best quality of life) and 155 (worst quality of life). Its age of application is the Spanish female population between 45 and 64 years old and it has scales to compare the results with younger women or of the same age. | The evaluation will be done at baseline before treatment and 6 weeks post treatment |
| Assessment of pain with the CPPQ-Mohedo (Chronic Pelvic Pain Floor) questionnaire | This questionnaire consists of 7 questions and is a screening tool to identify patients and include them in treatment programs, it allows the evaluation of results for treatments and clinical trials, as well as evaluating the prevalence of chronic pelvic pain in epidemiological studies. For the preparation of the CPPQ-Mohedo questionnaire, the NIH-CPSI (questionnaire for the evaluation of chronic prostatitis, male sex) was used and to test the ability to discriminate between healthy and unhealthy individuals, women and men, a paired study was carried out: 40 unhealthy men with 40 unhealthy women, each of whom was matched with six healthy controls for age and sex (480 total). Finally, CPPQ-Mohedo showed a similar discriminant capacity between men and women. The dimensions involved (pain and quality of life) showed internal consistency, with Cronbach's alpha coefficient being 0.75. | The evaluation will be done at baseline before treatment and 6 weeks post treatment |
| Evaluation of the impact of pelvic floor dysfunction symptoms with the PFDI-20 (Pelvic Floor Distress Inventory) questionnaire | This questionnaire is the validated Spanish version of the Pelvic Floor Distress Inventory Short Form (PFDI-20). It is a reliable and valid instrument to assess symptoms and quality of life in Spanish women with pelvic floor dysfunction. The Spanish version achieved good semantic, conceptual, idiomatic, and content equivalence, with Cronbach's alpha coefficient being 0.837. This questionnaire has 20 items grouped into 3 components: Genital Prolapse Symptom Impact Questionnaire (POPDI, Cronbach's alpha= 0.787) with 6 items that assess symptoms of genital prolapse; Colorectal-Anal Symptom Impact Questionnaire (CRADI, Cronbach's alpha= 0.630) with 8 items that assess colorectal-anal symptoms; Urinary Symptom Impact Questionnaire (UDI, Cronbach's alpha= 0.699) with 6 items that assess urinary symptoms. | The evaluation will be done at baseline before treatment and 6 weeks post treatment |
| Assesment of menopausal symptoms with the Menopause Rating Scale (MSR). | The Menopause Rating Scale (MRS) is a tool to assess the health-related quality of life of menopausal women. It is a standardized scale that meets psychometric standards, versioned in 9 languages. The scale was designed and standardized as a self-administered scale to (a) assess symptoms, (b) to assess the severity of symptoms over time, and (c) to measure changes before and after replacement therapy. menopause. It consists of 11 items (symptoms and complaints) evaluated from 0 (no complaint) to 4 (severe symptom). The degree of internal consistency (Cronbach's alpha coefficient) varies by country, ranging between 0.6 and 0.9. | The evaluation will be done at baseline before treatment and 6 weeks post treatment |
