Bipolar Radiofrequency for Genitourinary Syndrome of Menopause

Condition(s) studied

Investigational drug(s) / intervention(s)

Active bipolar radiofrequency therapy: Bipolar radiofrequency will be delivered using a non-ablative medical device for vulvovaginal tissue remodeling. Participants will receive six weekly sessions lasting approximately 40 minutes each. Each session will include three phases: an initial 5-minute external application using a capacitive electrode applied to the perineal and vulvar areas with gradual thermal increase to a comfortable sensation (approximately 4-5/10); a 10-minute intracavitary phase using a bipolar electrode with controlled temperature maintained between 41-43°C and systematic rotation for uniform energy distribution; and a final 5-minute external capacitive application replicating the first phase.

Sham radiofrequency procedure: The sham procedure will replicate the structure, duration, electrode placement, and anatomical application sites of the active intervention. Participants will undergo six weekly sessions lasting approximately 40 minutes, including an initial 5-minute external application to the perineal and vulvar areas, a 10-minute intracavitary electrode placement, and a final 5-minute external application. However, no therapeutic radiofrequency energy or thermal increase will be delivered.

Study summary

This randomized, sham-controlled clinical trial aims to evaluate the efficacy and safety of bipolar radiofrequency in the treatment of genitourinary syndrome of menopause (GSM) in postmenopausal women. Participants will be randomly assigned to receive either active bipolar radiofrequency treatment or a sham procedure.

The primary objective is to determine whether bipolar radiofrequency improves vaginal and sexual function. Secondary objectives include assessment of pain with vaginal penetration, vaginal lubrication and tissue distensibility, patient-reported vulvovaginal symptom severity, and treatment safety and tolerability.

Eligibility

Primary outcome measure(s)

• Change in Sexual Function (FSFI Total Score) — Baseline, 1 week after completion of treatment, and 3 months after completion of treatment
  Sexual function will be assessed using the Female Sexual Function Index (FSFI). The primary endpoints are the changes in total FSFI score from baseline to immediately post-treatment and from baseline to 3 months post-treatment to evaluate both immediate effect and durability.
• Change in Vaginal Health (Vaginal Health Index Total Score) — Baseline, 1 week after completion of treatment, and 3 months after completion of treatment
  Vaginal health will be assessed using the Vaginal Health Index (VHI). The primary endpoints are the changes in total VHI score from baseline to immediately post-treatment and from baseline to 3 months post-treatment to evaluate both immediate effect and durability.
