Sacral nerve stimulation, also known as sacral neuromodulation is an option for the management of patients with overactive bladder. The bladder is a hollow pelvic organ that stores urine before it is removed from the body. An overactive bladder, also called urge incontinence is a condition characterized by involuntary contraction of the muscles in the wall of the urinary bladder causing a sudden urge to urinate. The symptoms of an overactive bladder include sudden urge to urinate (urinary urgency), frequent urination, and involuntary loss of urine. Conservative treatment of overactive bladder includes lifestyle changes, pelvic floor muscle training, bladder training, and medications. Sacral nerve stimulation is considered in individuals who have found no relief through conservative therapy.
