Detailed Description
Vaginal rejuvenation is a catch-all term of trendy procedures which claim to provide relief of many issues affecting women's health, ranging from postmenopausal vulvovaginal symptoms (i.e. dryness, burning, itching), stress urinary incontinence, sexual dysfunction or discomfort, vaginal laxity, and labial appearance, amongst others2,3. Several companies have emerged with non-invasive or minimally-invasive technologies to alleviate these conditions which operate by radiofrequency delivery (IntraGen by Jeisys), Hybrid Fractional Laser (diVa by Sciton), or fractional CO2 laser (Mona Lisa Touch by Cynosure and Femi Lift by Alma Laser)4.
All of these technologies work theoretically by remodeling extracellular matrix configuration. It is of important note that radiofrequency therapies are typically delivered at 45-55 degrees Celsius in the tissues whereas the laser based products heat up to 60-70 degrees Celsius5. It is believed that "neocollagenesis" may only start if the temperatures are high enough and that such changes in the collagen matrix of the vagina could lead to durable vaginal wall changes. Sciton's diVa is hybrid fractional laser with wavelengths of 2940 nm and 1470 nm for ablation and coagulation, respectively, to treat vaginal tissue6. It is not known whether the changes experienced by patients are due to the reconfiguration of the extracellular matrix (ECM) deep in the vaginal wall or related to the acute swelling and inflammatory processes that occur at the surface of the vagina after these rejuvenation procedures.
The early anecdotal success reported on some user websites might be attributable to surface changes that may not be lasting or to possibly more lasting deeper muscular vaginal wall changes, which may or may not be beneficial. Based on the answer to this first set of questions, we might possibly surmise how such changes will ultimately improve vaginal dryness and/or stress urinary incontinence complaints.
An overriding question and concern is: Assuming these treatments induce collagen changes in the vagina, is it safe to induce such changes? If changes occur, are they long lasting? Can it age the vagina instead of making it "younger"? What are the long-term effects of doing so? Is tissue tightening really scar formation that may be deleterious in the future? The histological, genetic and dynamic changes following vaginal rejuvenation have never been studied.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: IntraGen RF
Patients will undergo treatment with radiofrequency device, using the device's standard protocol.
Patients will have 3 treatments space one month apart.
Each treatment will be a total of 20 minutes for internal treatment only.
Prior to treatment, the Zimmern probe will be used to measure vaginal wall elasticity and a 0.33mm biopsy will be taken.
At each visit, the Zimmern probe will be used.
Biopsies will be taken 3 months after final treatment.
|
IntraGen is a radiofrequency vaginal rejuvenation device FDA approved for use in dermatological and general surgical procedures for electrocoagulation and hemostasis.
The hand piece is a disposable monopolar applicator that is used to apply energy internally and externally.
|
Experimental: DiVA
Patients randomized into the DiVA treatment group will receive treatment per DiVA protocol.
Patients will have a total of 3 treatments, space 1 month apart.
Each treatment will last approximately 10 minutes.
Prior to treatment, the Zimmern probe will be used to measure vaginal wall elasticity and a 0.33mm biopsy will be taken.
At each visit, the Zimmern probe will be used.
Biopsies will be taken 3 months after final treatment.
|
DiVA device utilizes a hybrid fractional laser technology in a wand hand piece.
The hand piece is covered by a single use strengthened quartz dilator that allows the hand piece to rotate and provide treatment in a uniform manner.
|
Experimental: Dual Treatment
Patients previously randomized into the DiVA Sham and IntraGen Sham groups will be placed in the Dual Treatment group.
Patients will have a total of 3 dual treatments, spaced 1 month apart.
Each treatment will last approximately 20 minutes.
Prior to dual treatments, the Zimmern probe will be used to measure vaginal wall elasticity and a 0.33mm biopsy will be taken.
At each visit, the Zimmern probe will be used.
Biopsies will be taken at follow up visits.

Sham Comparator: Placebo Arm
Patients randomized into the Placebo arm will include participants from the DiVa PlaceboGroup and IntraGen Placebo Group combined and will receive treatment based on the DiVA Sham and IntraGen Sham protocols. DiVa Placebo: patients will undergo a three-part placebo treatment, spaced 1 month apart (+/- 10 days) of the vulvovaginal area. The vaginal HFL handpiece will be inserted into the vaginal canal but sub-therapeutic energy will not be delivered to the tissue. IntraGen Placebo: patients will undergo a three-part placebo treatment, space 1 month apart (+/- 10 days) of the vulvovaginal area. This will be achieved through application of the probe, but with applying sub-therapeutic energy to the tissue. |
