SUFU 2018: Safe and Effective Treatment of Overactive Bladder with a Miniaturized Rechargeable Sacral Neuromodulation System

Austin, TX ( Dr. Stefan De Wachter and colleagues presented the 6 month outcomes of a prospective, multicenter study of 51 patients with refractory OAB, treated with a rechargeable sacral neuromodulation system (r-SNM).  The implants were placed in a single procedure, to localize the S3 or S4 nerve.  3 day voiding diaries were completed at baseline and at follow up visits.  Patients deemed responders had a 50% reduction in voids and/or incontinence episodes, or with less than 8 voids per day.

71% of patients were considered responders at 4 weeks follow up.  This was maintained in 91% and 94% at 3 and 6 months follow up.  There was a reduction of 6 voids and 6 incontinence episodes per day at 6 months follow up.  Quality of life scores improved during this time as well.  83% of patients reported that they were moderately or very satisfied with their therapy.  The authors report that there were no serious device related adverse events. 

The authors reported an improvement in symptoms and patient satisfaction with this new rechargeable SNM system for refractory OAB, which they hope will lead to a decrease in frequency of revisions needed.
