The treatment procedure of this study is the laser treatment of the vagina and vulva with a "Magic Max" laser ("Magic Gyno" from August 2024) with subsequent monitoring.
Genetic testing: genetic testing for the following markers will be carried out:
ESR1 rs2234693 (estrogen receptor 1), ESR1 rs2228480 (estrogen receptor 1), COL3A1 rs1800255 (collagen type III alpha 1 chain), COL14A1 rs4870723 (collagen type XIV alpha 1 chain), MMP9 rs3918253 (matrix metallopeptidase 9), MMP10 rs17435959 (matrix metallopeptidase 10), LOXL1 rs2304719 (lysyl oxidase like 1), WNT4 rs3820282 (Wnt family member 4), MMP2 rs243865 (matrix metalloproteinase type 2), TIMP2 rs2277698 (tissue inhibitor of metalloproteinase-2), CD31 / PECAM1 rs1131012 (platelet-endothelial cell adhesion molecule 1), Ki67 rs11016076 (proliferation marker Ki67).
Treatment Technique:
Laser treatment procedure will be carried out in three stages. In total, three procedures will be performed with an interval of 4 weeks. Colporrhaphy will be carried out 1 month after last treatment. Three follow-up visits will follow: 1, 6 and 12 months after colporrhaphy.
During the procedure, the following sequence of actions will be performed:
1. st Stage - vaginal processing with a conical mirror handpiece,
2. nd Stage - vaginal processing with a corner mirror handpiece,
3. 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 1.5 millijoule (mJ). The procedure is performed without anesthesia. The doctor always focuses on the participant's feeling of warmth.
Participants of all groups will be tested with the general methods necessary to include the participant in the study at the first visit.
Control Technique:
In the control groups general surgery preparation protocol (sanitation of vagina) will be used as a therapeutic tool. After completing of preparation course, the operation will be performed.
Operation technique:
A part of the stretched vaginal wall in the posterior fornix area including the mucous membrane and muscle layer will be excised with its further suturing during colporrhaphy surgery (the excised material will be examined). This will allow comparing the vaginal walls state at the time of surgery after laser treatment and without it, and with the age norm.
Participants of all groups will be tested with the general methods necessary to include the patient in the study at the first visit.
For the laser treatment group: Studies will be carried out using filling out the questionnaires, Vaginal Health Index determination, and Doppler ultrasonography, and then laser treatment of the vagina, vulva and paraurethral region will be performed during the 2nd, 3d, and 4th visits. Filling out the questionnaires, Vaginal Health Index determination, and Doppler ultrasonography will be repeated during the 5th visit (1 month after last laser treatment and 1 day before colporrhaphy). Vaginal biopsy for histological examination, immunohistochemical examination, and optical coherence tomography (elastography) will be carried out during A/P colporrhaphy in the 6th visit. Physical examination only will be carried out during the 7th (follow-up) visit - 1 month after colporrhaphy. Filling out the questionnaires, Vaginal Health Index determination, and Doppler ultrasonography will be carried out during 8th and 9th (follow-up) visits - 6 and 12 months after colporrhaphy.
For control group 1: Studies will be carried out using filling out the questionnaires, Vaginal Health Index determination, and Doppler ultrasonography during the 1st visit after including patient. Vaginal biopsy for histological examination, immunohistochemical examination, and optical coherence tomography (elastography) will be carried out during A/P colporrhaphy in the 2nd visit. Physical examination only will be carried out during the 3th (follow-up) visit - 1 month after colporrhaphy. Filling out the questionnaire, Vaginal Health Index determination, and Doppler ultrasonography will be carried out during 4th and 5th (follow-up) visits - 6 and 12 months after colporrhaphy. Buccal smear collection will be carried out during 4th follow up visit (6 months after colporrhaphy).
Thus, a direct comparison between laser preoperational treatment and lack of preoperational treatment will be made during the investigation, 6 and 12 months after the end of each type of treatment.
For control group 2: Studies will be carried out using filling out the questionnaires, Vaginal Health Index determination, and Doppler ultrasonography during the 1st visit after including participant. Vaginal biopsy for histological examination, immunohistochemical examination, and optical coherence tomography (elastography) will be carried out during A/P colporrhaphy in the 2nd visit (no more than 1 month after 1st visit). The obtained data will allow to study the tissues of the vaginal wall in normal conditions.
The study will be carried out with the participation of several clinics:
(recruting, filling out IRC - Individual Registration Cards, buccal smear collection) (colporrhaphy and biopsy)
1. Privolzhsky Research Medical University (main scientific coordinator, histological examination, immunohistochemical examination, and optical coherence tomography (elastography)), genetic examination,

6. Birth house №4 of the Leninskiy District of Nizhny Novgorod named after A.F. Dobrotina (colporrhaphy and biopsy) All data obtained during the study will be transferred to the manufacturer of laser equipment "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.
