Study summary

This is a randomized controlled trial to evaluate the use of LASER, Micro Ablative radiofrequency and topic strogen to treat symptoms of vulvovaginal atrophy of post menopause.

Read the detailed description

Post menopause women with moderate or severe signs or symptoms of vulvovaginal atrophy will be eligible for the study.

The patients will be randomized to receive one of the three intravaginal therapies: LASER, Micro Ablative radiofrequency or Estriol. The applications will occur in the interval of 30 days for 3 times, for LASER and Radiofrequency groups. For the estriol group, the application will be done by the patient, daily for 2 weeks and them twice a week for 3 months, and each 30 days, the patients will have an appointment when will be checked the weight of the estriol tube, to verify the correct use.

The follow-up visits will occur 30, 90, 180 and 360 days after the conclusion of the third month of treatment.

Will be evaluated: vulvar and vaginal histology before and after the use of LASER, radiofrequency or estriol; microbiota and vaginal pH before and after the use of LASER, radiofrequency or estriol; extracellular matrix and metalloproteinases in the remodeling of vulvovaginal collagen induced by estrogen, LASER and radiofrequency; quality of life, sexual dysfunctions and complaints before and after the use of LASER, radiofrequency or hormones; metabolomics and vaginal microbiome.

    The patients will receive 3 consecutive applications of intravaginal and vulvar MIcro ablative radiofrequency, according to the manufacturer protocol for vaginal atrophy. The applications will be separated by the interval of 30 days

    Procedure: Microablative Radiofrequency

  • Active comparator
    Estriol

    The patient will use intravaginal estriol, daily for 2 weeks and them twice a week for 3 months . Each 30 days, the patients will have an appointment when will be checked the weight of the estriol tube to verify the correct use.

    Drug: Estriol

Interventions

  • ProcedureLASER

    Use of the SmartXide Touch V²LR, Co2 Laser System to perform ambulatory intravaginal and vulvar application of LASER, to postmenopausal genitourinary syndrome.

What researchers measure

Primary outcomes

  1. Clinical Improvement of signs and symptoms postmenopausal genitourinary syndrome with intravaginal LASER, Microablative Radiofrequency, and topic estriol

    Will be applied a Visual Analogic Scale (0-10) to access the improvement of genitourinary signs and symptoms, the results of the three groups will be compared

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 22, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
