Patients with refractory interstitial cystitis (IC) underwent testing with sacral nerve modulation via either a traditional percutaneous approach or a staged procedure. Implanted patients were followed with scaled questionnaires and voiding diaries. Twenty-six patients who had a permanent InterStim placed had a reduction in 24-h voids of 51%. More than two-thirds of patients reported a moderate or marked improvement in urinary frequency, urgency, pelvic pain, pelvic pressure, incontinence and overall quality of life. The test to implant rate of a traditional percutaneous procedure was 52%, compared to a staged procedure of 94%. Assessing sensory response at the time of implant reduced the reoperation rate from 43% to 0%. Ninety-six per cent stated they would undergo an implant again and recommend the therapy to a friend. We concluded that sacral nerve modulation can treat refractory IC symptoms. The response to therapy and the reoperation rate are dependent on the technique used to test and implant the device.
