Overview

The goal of this Safety and efficacy of transvaginal Detrusor Nerve Ablation for treatment of overactive bladder symptoms, including refractory overactive bladder The main questions it aims to answer are: •Change from baseline to the end of treatment in a 3-day diary analysis to assess the reduction of urgency incontinence episodes. \[Time Frame: 3 months\] Subjects will undergo one treatment session and be reassessed at 4 weeks post-treatment. If less than a 50% improvement is noted, a second and third treatment session will be performed at 4-week intervals. If more than a 50% improvement is noted, patients will be followed longitudinally to assess the durability of the treatment. Investigators will have the ability to initiate a second and or third treatment on an individual basis. Follow-up will occur at 3- months, 6-months and 12 months after the subject's last treatment.

Assessment of the impact of the treatment on Overactive Bladder symptoms

Measured by the Incontinence Impact Questionnaire Total Score. Normative values for a general population, 10% of whom scored above 4.8 on IIQ-7. Values obtained from patients with severe incontinence indicate that a score \> 70 on the IIQ signifies a poor QOL. Lower scores on IIQ-7 may identify more females who are bothered by urinary incontinence. 7 items are divided into four domains (physical activity, travel, social relationships, emotional health). Item-level scores are rated on a four-point Likert scale (where 0=not at all and 3=greatly), determined by the self-reported impact of symptoms related to urinary incontinence. The average score of items responded to is calculated. The average, which ranges from 0 to 3, is multiplied by 33 1/3 to put scores on a scale of 0 to 100.

Patient-reported Pain assessment

The subject will be asked to rate the severity from 0 to 10, with 0 equaling no symptoms and 10 equaling the worst possible symptoms. A number is obtained by measuring up to the point the subject has indicated.

Time frame: treatment procedure

Patient-reported outcome measure

Patient perception of bladder condition and device acceptance measured by Patient Satisfaction Questionnaire. 6 points Likert scale, grading from 0 to 5. A lower score indicates a better outcome.
