Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Women and men above 18 years old with gender percentages reflective of disease prevalence in the U.S. population
  • Individual with diagnosis of overactive bladder with urgency urinary incontinence.
  • Individual has at least one urgency urinary incontinence episode on each of three days as determined on a 3-day voiding diary.
  • Individual gives written informed consent.
  • Individual is mentally competent and able to understand all study requirements.
  • Individual is willing and able to complete a 3-day voiding diary and quality of life questionnaire.
  • Individual is without pharmacological treatment of overactive bladder (anticholinergic and β3-adrenoceptor agonists) for 2 weeks prior to baseline or longer if the physician judges that the therapeutic effect is still present.
  • Individual is intolerant of or has an inadequate response to any of anticholinergics, β3-adrenoceptor agonists, onabotulinumtoxinA, or who have undergone percutaneous tibial nerve stimulation (PTNS).
  • Individual is determined to be a suitable surgical candidate by physician.
  • Individual is appropriate for eCoin treatment based on the US FDA-approved IFU requirements.

You may not qualify if:

  • Individual is not appropriate for eCoin therapy based upon the US FDA-approved IFU requirements.
  • Individual has clinically significant bladder outlet obstruction. (Suspected bladder outlet obstruction will be initially assessed by uroflow study with those having a maximum flow rate \< 15mL/s requiring additional evaluation.)
  • Individual has predominantly stress urinary incontinence (greater than 1/3 of leaks on baseline diary are stress).
  • Individual has an active urinary tract infection at time of enrollment.
  • Individual has known polyuria.
  • Individual has significant lower urinary tract pain or has been diagnosed with interstitial cystitis or bladder pain syndrome.
  • Individual has abnormal post void residual (i.e. greater than 200 cc initially and on repeat testing after double voiding)
  • Individual has clinically significant urethral stricture disease or bladder neck contracture. (Suspected disease or contracture will be initially assessed by uroflow study with those having a maximum flow rate \< 15mL/s requiring additional evaluation.)
  • Individual has chronic venous insufficiency with a history of skin change (hyperpigmentation, lipodermatosclerosis, ulceration) in the ankle region.
  • Individual has morbid obesity and in the opinion of the investigator is not a good candidate for the study.
  • Individual has had diagnosis of bladder, urethral, or prostate cancer.
  • Individual has had a prior anti-stress incontinence sling surgery within the last year.
  • Individual is pregnant or intends to become pregnant during the study.
  • Individual has the presence of urinary fistula, bladder stone, or interstitial cystitis.
  • Individual has uncontrolled diabetes mellitus (Hemoglobin A1C\>7) or diabetes with significant peripheral complications. (Uncontrolled diabetes will be ruled out by blood test excluding those with Hemoglobin A1C\>7).
