Overactive Bladder

Keywords

OAB symptoms of urgency, frequency, and urge incontinence

Brief summary

The purpose of this study is to compare percutaneous tibial nerve stimulation (PTNS) to drug therapy for the treatment of symptoms of overactive bladder (OAB).

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).

Frequency of Voids at 12 WeeksBaseline to 12 weeksTo demonstrate that the Urgent PC system is as effective as or more effective (noninferior) than tolterodine (Detrol LA) in changing the frequency of urinary voids per day after 12 weeks of therapy. The voiding diaries completed at 12 weeks were compared to the baseline voiding diaries.

To demonstrate that the Urgent PC system is as effective as or more effective (noninferior) than tolterodine (Detrol LA) in changing the frequency of urinary voids per day after 12 weeks of therapy. The voiding diaries completed at 12 weeks were compared to the baseline voiding diaries.
