AUA 2011 - Insight into percutaneous tibial nerve stimulation: Critical evaluation of the SUmiT Trial - Session Highlights

WASHINGTON, DC USA ( - This was an interesting review by Dr. Kenneth Peters, who also presented this treatment in his State-of-the Art lecture: New & Emerging Concepts in Neuromodulation on Monday’s plenary session.

The treatment discussed is the Urgent® PC percutaneous tibial nerve stimulation (PTNS) that delivers minimally invasive stimulation of the posterior tibial nerve. This is a review of the SUmiT Trial previously reported and published. Dr Peters looked at Global Response Assessment (GRA) and OAB-q quality of life responses at the 7 and 13 weeks. It was noted that 12 weekly treatment sessions are needed to effectively treat OAB. All GRA outcomes were statistically significant at 13 weeks compared to baseline, but outcomes were not significant at 7 weeks. Similarly, OAB-q quality of life questionnaires were statistically significant for improvement at 13 weeks, but not significant at 7 weeks between treatment groups.
