Overactive bladder (OAB) is a urologic condition that negatively impacts quality of life. Sacral neuromodulation (SNM) is a safe and effective treatment option that has been studied extensively in patients with severe and refractory OAB. SNM significantly reduces urgency, frequency, and incontinence while also improving quality of life. Although SNM is not currently indicated for the treatment of OAB symptoms due to neurologic disease, recent literature suggests that these patients may also benefit from SNM. Other areas requiring further investigation include reduction of adverse events associated with SNM and the overall cost benefit ratio of SNM.
