Sacral nerve stimulation delivers nonpainful electrical pulses to the sacral nerves that modulate the reflexes that control the bladder, bowels, and pelvic floor musculature. This relatively simple procedure was generated to improve and restore function in patients with a variety of pelvic floor disorders. Currently this therapy is approved for use in patients with urgency urinary incontinence, urinary urgency–frequency, nonobstructive urinary retention, and fecal incontinence. This review includes the history of this treatment modality, explains the mechanism of action, and describes the procedure for implantation of this device. Additionally, advancements in this treatment over the past two decades and landmark literature to date regarding sacral nerve stimulation are reviewed. Current literature regarding off-label uses of this treatment modality for a variety of pelvic floor disorders is also discussed.
Sacral nerve stimulation for refractory voiding and bowel dysfunction has provided an effective minimally invasive therapy for patients for whom more conservative treatments have failed.
