Study summary

The investigator wants to evaluate the efficacy of a specific intravaginal Electrical Muscle Stimulation (EMS), in the treatment of exclusive or predominant stress urinary incontinence (SUI) symptoms in women. The investigator's aim is to determine the device's impact (the device is VTone) on reducing urinary incontinence episodes and on improving women's quality of life.

Study arms

  • Experimental
    Women with stress urinary incontinence treated with intravaginal electrical muscle stimulation

    We will include women suffering from stress urinary incontinence who will be treated with intravaginal electrical muscle stimulation with a device called VTone. VTone is a small anatomically shaped applicator that delivers intravaginal electrical muscle stimulation This device includes an ogival, circular body, with a handle at one end of the body and a head at the other end of the body. The head includes a substantially flat, metallic surface. The device should be used with gel. The treatment will include 6 sessions (sessions will be planned once a week) and women will be asked to fill in a bladder voiding diary and validated questionnnaires at baseline and at follow up visits (one and three months after the last treatment).

    Device: Electrical intravaginal muscle stimulation

Interventions

  • DeviceElectrical intravaginal muscle stimulation

    The device includes an ogival, circular body, with a handle at one end of the body, a head at the other end of the body. The head includes a substantially flat, metallic surface. The device and the head are sized and configured to be received in a patient's vagina. The device should be used with gel. Patients will be trated with six sessions (planned once a week for a total of six week).

What researchers measure

Primary outcomes

  1. Variation in patient bladder voiding diaries' results at follow up visits versus baseline

    Eligible subjects will receive a total of 8 treatments (once a week) using the transvaginal electrical stimulation. All subjects will be required to return to the clinic at 1 month and 3 months after the last treatment. At baseline and during the two follow up visits patients will be asked to fill in a bladder voiding diary.

    Time frame: Follow up visits: 1 month and 3 months after the last session of treatment
