Trial summary

The investigator hypothesizes that controlled delivery of low heat (45-50 Centigrade) to the sub-detrusor and detrusor muscle can ablate the autonomic nerve endings and control overactive bladder symptoms without causing significant damage to the surrounding structures. Read more about this study

About this study

The investigator hypothesizes that controlled delivery of low heat (45-50 Centigrade) to the sub-detrusor and detrusor muscle can ablate the autonomic nerve endings and control overactive bladder symptoms without causing significant damage to the surrounding structures. Low heat in such a manner is below urethral sensation and enables office treatment. The transvaginal approach is non-invasive and improves overactive bladder (OAB) symptoms and patients' quality of life. The investigator believes that the RF administration results could be equal or better for first-line treated patients compared to pharmacological refractory patients.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • RadiofrequencyDevice

    According to the study protocol, eligible subjects will receive one treatment within 3 weeks of screening. After one month, if there is no satisfactory result, a second treatment will be administered, and after another month, the patient will be evaluated. If there is still no end point, a third treatment will be given. It should be noted that the second and third treatments will only be performed if there is no satisfactory result after the previous treatment. Treatment area: Treatment area will include vaginal canal.

    Treatment Procedure:

    • Subjects receive HYPNOS treatment with device using radiofrequency (RF). Treat vaginal canal at the depth starting from approximately 3.5cm from introitus to the distal end of vagina. Radially the treatment area is from 9 to 3 o'clock.
    • Patient should empty bladder prior to treatment
    • Position patient in lithotomy position
    • Set energy to levels well tolerated by the subject. Suggested settings: Burst Mode 7mm, 1 pass.
