What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Performance/Effectiveness - Improvement in Quality of Life scoring (OAB)
Time Frame: 3 months
International Consultation on Incontinence Questionnaire Overactive Bladder Quality of Life (ICIQ-OABqol): questions in each subscale are scored by a summed range of 0 to 100, with a higher score indicating better quality of life. Overall score ≥ 10 points from baseline to follow-up is indicative of a clinically meaningful improvement.
3 months
Adverse event reporting (Safety)
Time Frame: 3 months
Device-related, procedure-related and all serious adverse events
3 months
Performance/Effectiveness - Improvement in Fecal Incontinence Survey
Time Frame: 3 months
Cleveland Clinic Florida - Fecal Incontinence Score (CCF-FIS): includes 5 items (solid, liquid, gas, wears pad and lifestyle alteration) and 5 frequencies (never = 0, rarely = 1, sometimes = 2, usually = 3, always = 4). Scores range from 0 for full continence to 20 for complete incontinence. A higher score is indicative of the severity of fecal incontinence.
3 months

Scores range from 0 for full continence to 20 for complete incontinence. A higher score is indicative of the severity of fecal incontinence.
1 year
Performance/Effectiveness - Improvement in Quality of Life Survey (FI)
Time Frame: 3 months, 6 months, 1 year
Fecal Incontinence Quality of Life (FIQoL): includes four different subscales: lifestyle, coping/behavior, depression/self-perception and embarrassment. Subscale scores range from 1 to 5, with 1 indicating lower functional status of qualify of life.
