Brief Summary
This trial is a prospective, multicenter, single-arm study of the safety and effectiveness of eCoinTM tibial nerve stimulation in subjects having overactive bladder (OAB) with urgency urinary incontinence (UUI). The study will evaluate changes from baseline in OAB symptoms as measured by voiding diaries and patient reported-outcomes through 48 weeks of eCoinTM therapy or 52 weeks of implantation.

Eligibility Criteria
You may qualify if:
- Women and men between 18 and 80 years old.
- Diagnosis of overactive bladder with urgency urinary incontinence or mixed urge and stress incontinence with a predominant urgency component (selfreported), for at least 6 months.
- Individual is without pharmacological treatment of overactive bladder (antimuscarinics and beta-3 agonists).
- Individual is intolerant of or has an inadequate response to any of anticholinergics, β3-adrenoceptor agonists, onabotulinumtoxinA, or percutaneous tibial nerve stimulation.
You may not qualify if:
- Predominant stress urinary incontinence with more than 1/3 stress urinary incontinent episodes when compared to total urinary incontinent episodes.
- Clinically significant bladder outlet obstruction.
- Clinically significant pelvic organ prolapse beyond the hymenal ring.
- Inadequate skin integrity or any evidence of an infection or inflammation in either lower leg.

Limitations and Caveats
A limitation of the study was the lack of blinding and comparison. Considering that neuromodulation studies are generally not blinded since the therapy itself is sensed, a control group with a similar safety profile to eCoin could not be achieved. We also acknowledge that a 12-month endpoint provides only medium-term data on the durability of response and future longer follow up data will be needed.
