Design outcomes

Primary

MeasureTime frame
Overactive Bladder Cohort primary objective; The primary objective for the overactive bladder cohort of the study is to demonstrate an improvement in Overactive Bladder Quality of Life (OAB-q) Questionnaire Health Related Quality of Life (HRQL) total score at 3 months post-implant compared to baseline. Fecal Incontinence Cohort primary objective; The primary objective for the fecal incontinence cohort of the study is to demonstrate an improvement in Cleveland Clinic Incontinence Score (CCIS) at 3 months post-implant compared to baseline. Non-Obstructive Urinary Retention Cohort primary objective: The primary objective for the non-obstructive urinary retention cohort of the study is to demonstrate an improvement in number of clean intermittent self-catheterizations (CISC) per day at 3 months postimplant compared to baseline. All additional objectives per cohort can be found under section 5 of the CIP.
