Primary Outcome Measures:
  • The Global Response Assessment (GRA) for Overall Bladder Symptoms to Compare the Proportion of Subjects Reporting "Moderately" or "Markedly Improved" Responses on the GRA After 12 Interventions of Randomized Therapy, in an Intent to Treat Analysis. [ Time Frame: 13 weeks ]
    A responder was defined as reporting bladder symptoms as moderately or markedly improved on a 7-level GRA at week 13 after completing 12, 30-minute, consecutive weekly intervention sessions.

Enrollment: 220
Study Start Date: September 2008
Study Completion Date: June 2009
Primary Completion Date: June 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Urgent PC Device: Urgent PC Neuromodulation System
The Urgent PC Neuromodulation System is a minimally invasive neuromodulation system designed to deliver retrograde access to the sacral nerve through percutaneous electrical stimulation of the tibial nerve. The method of treatment is referred to as Percutaneous Tibial Nerve Stimulation (PTNS).
No Intervention: Sham / Placebo

  • Self-reported bladder symptoms present > 3 months
  • Self-reported failed conservative care (i.e., dietary restriction, fluid restriction, bladder training, behavioral modification, pelvic muscle training, biofeedback, etc.)
