Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Fractional bipolar radiofrequency therapy has emerged as a promising minimally invasive treatment modality. This non-ablative approach uses fractional RF technology with microneedles to deliver thermal injury to the subdermis, stimulating collagen production, promoting tissue remodeling and improving tissue tightening, potentially addressing symptoms associated with vaginal laxity. Recent advancements in RF technology have led to its increasing use in aesthetic and gynecological applications. Evidence suggests that RF microneedling effectively remodels subdermal fat and improves skin firmness. However, no previous study has been conducted on the treatment of vaginal laxity using fractional bipolar radiofrequency (with microneedling), highlighting the need for rigorous scientific evaluation to provide conclusive evidence on its effectiveness, including improvements in sexual function and safety.
Additionally, the use of 3D transvaginal ultrasound to measure vaginal wall thickness is still limited in clinical studies. It is necessary to investigate whether fractional bipolar radiofrequency can improve vaginal wall thickness and explore the association between vaginal wall thickness and the clinical presentation of vaginal laxity in patients.
This study aims to address this gap by conducting a first randomized controlled trial to compare the efficacy of fractional bipolar radiofrequency therapy with a sham treatment in premenopausal women. By employing a methodological approach, this research seeks to contribute valuable insights into the clinical benefits of fractional bipolar radiofrequency therapy, ultimately guiding future treatment strategies for vaginal laxity.
Primary Objective:
\- To evaluate and compare the efficacy of fractional bipolar radiofrequency therapy versus a sham treatment for vaginal laxity in premenopausal women.
Secondary Objectives (if any):
* To evaluate patient satisfaction and changes in sexual function before and after fractional bipolar radiofrequency therapy VS sham treatment.
* To assess alterations in vaginal thickness based on 3D transvaginal ultrasound before and after fractional bipolar radiofrequency therapy Vs sham treatment.
* To evaluate any potential side effects or adverse events associated with intravaginal fractional bipolar radiofrequency therapy.
Study design/methodology:
* Study design: A double-blind, randomized controlled trial
* Study Population: Premenopausal women with clinically diagnosed vaginal laxity who are sexually active.
Specifications of Fractional Radiofrequency energy (Morpheus8V from Inmode company)
* Configuration: 24 gold coated micropins
* Depth profile: 1-3 mm
* Pin profile: 300um diameter with insulated 0.5 mm conductive tip
* Treatment depth: operator adjustable
* Principle: Microneedling with fractional RF: delivery RF energy to depths from 0.5-3.5 mm below the surface, induced additional thermal stimulation, superior neo-collagenesis than with RF energy alone
* Treatment was performed using the Empower RF Morpheus8V device (InMode), applying fractional bipolar RF energy in a stamping method with 50% overlap along the entire length of the vagina to the introitus, at intervals of 9, 10:30, 12, 1:30, 3, 4:30, 6, and 7:30.
* Two passes were made at depths of 1, 2, and 3 mm.
Participant timeline and Procedures:
Week 0:
* Screening and enrollment, Eligibility screening, Inform consent, General advice for PFMT
* Baseline assessment: Demographic data, Questionnaires (VLQ, FSFI, FGSIS, ICIQ-VS)
* Physical examination: PV: Evaluate genital hiatus (Gh), vaginal caliber
* 3D endovaginal US: Evaluate baseline vaginal thickness.
Week 1
* Intervention \*Radiofrequency therapy VS Sham 72 hours post-intervention:
* Telemedicine Inquire with the patients about any adverse events they may have experienced following the intervention
Week 4 (1-month post-intervention):
\- Telemedicine/questionnaires by mail Questionnaires (VLQ, FSFI, FGSIS, ICIQ-VS), Assessment for any adverse events, The Patient Global Impression of Improvement (PGI-I)
Week 13 (3 months post-intervention):
* Follow-up visit Questionnaires (VLQ, FSFI, FGSIS, ICIQ-VS)
* Assessment for any adverse events
* The Patient Global Impression of Improvement (PGI-I)
* Physical examination PV: Evaluate genital hiatus (Gh), vaginal caliber
* 3D endovaginal US Evaluate vaginal thickness post-RF treatment
Discontinuation/withdrawal criteria:
* Adverse Events: Development of serious adverse effects or complications related to the therapy, such as severe pain, infection, or significant bleeding. Or any signs or concerns that the participant might not be safe to continue, as determined by the investigator.
* Pregnancy: If a participant becomes pregnant during the study, they may need to withdraw to ensure safety for both the mother and the fetus.
* Medical Conditions: Emergence of new medical conditions or exacerbation of existing conditions that could complicate participation or the study's objectives such as active genital infection.
* Patient Preference: Participant's decision to withdraw from the study for personal reasons, including dissatisfaction with the treatment or its effects.
Adverse Event Reporting:
* Pain, discomfort, or a burning sensation during or after the procedure.
* Worsening of urinary symptoms
* The presence of vaginal burn
* Vaginal discharge
* The presence of abnormal vaginal bleeding (spotting).
* Swelling and bruising: Mild to moderate swelling and bruising at the treatment site
* Infection: There is a small risk of infection at the site of microneedling if proper post-treatment care is not followed.
