Selection of Ideal Candidates for Neuromodulation in Refractory Overactive Bladder

Sacral neuromodulation is a minimally invasive, reversible treatment option that has been approved by the US Food and Drug Administration for patients with urgency/frequency and urge incontinence. While long-term success rates are high, the high treatment cost and the need for operative revision or explantation in cases of failure make the selection of ideal candidates particularly important. Because predictive factors for success and the exact mechanism of action are not known, physicians must rely on a preimplantation test procedure, either in the office or in the operating room, to select patients for implantation of a pulse generator. In this paper, we review the recent literature on performing a test procedure with both temporary and permanent leads and the selection of optimal candidates for sacral neuromodulation therapy.
