Vulvovaginal Atrophy Correction Using Neodymium Laser

The aim of this prospective study is characteristic of changes in the vaginal wall and vulva after treatment of neodymium laser radiation with a wavelength of 1064 nm. To assess the condition of the vaginal walls and vulva before and after laser treatment, the following methods will be used: vaginal health index, perineometry, elastography of vulva, cytological methods. Female Sexual Function Index (FSFI), The Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12), Vulvovaginal Symptoms Questionnaire (VSQ), Visual Analogue Scale (VAS) will be used to collect feedback on changes in the participants life quality. Total up to 120 participants with postmenopausal atrophy will be involved in the study. Participants will be divided into three groups: laser treatment group, topical hormones treatment group, and both laser treatment with topical hormones application group, by 40 participants in each. The time intervals between tests will be the same for all groups. Thus, a direct comparison between conventional treatment (topical hormones), laser treatment and combine laser and topical hormones therapy of the vaginal atrophy will be made. The main hypothesis of the study is improvement in condition of the vaginal walls after laser treatment and laser treatment with hormones application compared with the initial state of not less than thirty percent of participants, and improvement in condition on average compared with the hormones only therapy group.

The principle of participant distribution into groups is the main method of treatment of postmenopausal vaginal atrophy. Total up to 120 participants with postmenopausal atrophy will be involved in the study. Participants will be divided into three groups: laser treatment group, topical hormones treatment group, laser treatment with topical hormones application, by 40 participants in each. The types of examination of each group are the same and include: General methods: physical examination, clinical blood analysis with glucose determination, clinical urine test, vaginal smear for flora and oncocytology, pelvic ultrasound. Special methods: filling out the questionnaire (Female Sexual Function Index, The Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire, Vulvovaginal Symptoms Questionnaire), Vaginal Health Index determination, Visual Analogue Scale (VAS) determination, perineometry, vaginal smear for cytology, elastography of vulva, microbiological vaginal smear stained by Gram. The treatment procedure of this study is the laser treatment of the vagina and vulva with a "Magic Max" laser with subsequent monitoring. Treatment Technique: Laser treatment procedure will be carried out in three stages. In total, three procedures will be performed with an interval of 4-6 weeks. Two follow-up visits will follow: 1 and 6 months after the last procedure. During the procedure, the following sequence of actions will be performed: st Stage - vaginal processing with a conical mirror handpiece, nd Stage - vaginal processing with a corner mirror handpiece, rd Stage - external vulva and paraurethral region processing with a switched beam diameter handpiece. Laser radiation is emitted by a series of pulses following each other through a pause. The duration of one pulse is 20-200 nanoseconds (ns), the pause between pulses is 30 microseconds (us). The energy of one pulse is about 1 millijoule (mJ). The procedure is performed without anesthesia. The doctor always focuses on the participant's feeling of warmth. Hormone treatment procedure. Local hormone therapy with estriol will be used as a therapeutic tool for the control group. The course of treatment will be of 2 weeks of daily use, and then a maintenance therapy will be used of 2 times a week for 12 months to prevent symptoms. Participants of all groups will be tested with the general methods necessary to include the participant in the study at the first visit. For the laser treatment group: Studies will be carried out using special methods and then laser treatment of the vagina and vulva and paraurethral region will be performed during the 2nd, 3d, and 4th visits. Studies with all special methods will be performed during the 1st (before the start of treatment) visit. Vaginal health index, pH-measurement, perineometry, and filling of questionnaires will be performed during 3d-6th visits. Cytological investigation and elastography of vulva will be performed during 5th (1 month after the last procedure) and 6th (6 months after the last procedure). For the hormone treatment group: Studies with all special methods will be performed during the 1st (before the start of treatment) visit. Vaginal health index, pH-measurement, perineometry, and filling of questionnaires will be performed during 3d-6th visits. Cytological investigation and Doppler sonography will be performed during 5th (1 month after the last procedure) and 6th (6 months after the last procedure). Hormone therapy will begin from the 2nd visit. All subsequent visits will be carried out at the same time intervals as for the laser treatment group, using studies with special methods. The 3d visit will be in 4-6 weeks after the start of treatment, the 4th will be in 4-6 weeks after the 3d visit, the 5th - 1 month after the 4th, the 6th - 6 months after the 4th. For the combine laser treatment with topical hormones application group: laser treatment of the vagina and vulva and paraurethral region will be performed during the 2nd, 3d, and 4th visits. At the same time, starting from 2nd visit hormone therapy will be started. All subsequent visits will be carried out at the same time intervals as for the laser treatment group and hormone treatment group, using studies with special methods. Thus, a direct comparison between conventional treatment (topical hormones), laser treatment and combine therapy of the vaginal atrophy will be made during the treatment, as well as on follow-up visits in 1 and 6 months after the end of each type of treatment. The study will be carried out with the participation of FSBI "National Medical Research Center For Obstetrics, Gynecology And Perinatology Named After Academician V.I.Kulakov" MINISTRY OF HEALTHCARE OF THE RUSSIAN FEDERATION All data obtained during the study will be transferred to the manufacturer of "MeLSyTech" Ltd. The study will be monitored by "MeLSyTech" Ltd as follows: Once a month, monitoring of provided documents (copies of individual registration records of participants, informed consent, test results) for the complete filling of the forms; the clarity of filling out forms, the possibility of systematizing information from the forms of their assessment; Once every six months, monitoring will be conducted with a coordinator visit of the research center and analysis activities, such as participants recruitment, data collection, data management, data analysis, reporting for adverse events, and change management; Once a year, the investigator submits a clinical evaluation report to the sponsor. Statistics The analysis will be carried out both between groups of participants receiving different types of therapy (analysis of independent groups) and within groups at different time intervals (analysis of matched groups). Before performing statistical analysis of the data, the distribution type of the variables will be assessed. To assess the normality of distribution for each variable, histograms of frequency distributions will be visually evaluated, indicators of skewness, kurtosis, and the D'Agostino-Pearson normality test will be used. In addition to checking the type of distribution of variables, the equality of variances of the studied groups will be assessed using the methods of analysis of variance, in particular the Brown-Forsythe test. Methods of descriptive analysis will be used depending on the type of distribution of the variable. With a normal distribution, the mean (M) and standard deviation (SD) will be calculated. In case of an nongaussian distribution, the median (Me) and interquartile range will be calculated. Different algorithms of statistical analysis will be applied depending on the type of distribution of variables. Comparison of the paired and unpaired groups with a normal distribution, in case of the equality of the variances, will be carried out by the methods of analysis of variance ANOVA. Comparison of groups in pairs will be performed using the post-hoc method of posterior multiple comparisons (Tukey test). Comparison of groups in which variables do not follow the normal distribution will be carried out using the methods of nonparametric analysis of variations: the Kruskal-Wallis test (ANOVA tests) for independent groups and the Friedman test for matched groups. Dunn's multiple comparison test will be used to assess intergroup differences. Before assessing intergroup differences, the initial samples (1 visit) will be analyzed for identity using ANOVA or nonparametric Kruskal-Wallis tests (depending on the type of data). In case of significant differences in the samples, the search and removal of extremely deviating values (outliers) will be carried out. Differences will be considered statistically significant if the significance P values are <0.05.

The treatment method cannot be hidden from the participants and the researcher because of the very different method of treatment: laser treatment and the use of local hormones on their own. However, the specialists involved in the study (cytologist and ultrasound specialist) will not know which group the participant belongs to. The researcher will refer participants (or their materials) to these specialists, indicating their name and visit number. The Researcher will keep a document matching the participant's name and number. The conversation will be held with participants. A participant must not disclose his group when visiting an ultrasound specialist.
