InterStim stage 2

The therapy uses a small implanted medical device to send mild electrical pulses to a nerve located just above the tail bone. These nerves are called sacral nerves. The sacral nerves—specifically S2, S3 and S4—activate or inhibit muscles and organs that contribute to urinary control: the bladder, sphincter and pelvic floor muscles. The electrical stimulation may eliminate or reduce certain bladder control functions in some people. This stimulation may facilitate the communication between the brain and bladder, and may relieve the symptoms of urinary retention or symptoms of overactive bladder, including urinary urge incontinence and significant symptoms of urgency-frequency in some patients.
Prior to your surgery you should be given a Patient Therapy Guide. Read this prior to your surgery so any final questions can be answered.
