Outcome Measures

Primary Outcomes (1)

  • 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.

    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.

Study Arms (2)

Urgent PC

ACTIVE COMPARATOR
Device: Urgent PC Neuromodulation System

Sham / Placebo

NO INTERVENTION

Interventions

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).
