Brief Summary
Purpose:
- 1.To demonstrate better symptoms control (pain, urinary urgency and frequency) with sacral neuromodulation (SNM) in patients with interstitial cystitis /painful bladder syndrome (IC/PBS) using a stimulation frequency of 40 hertz (experimental) compared to a frequency of 14 hertz (standard).
- 2.The evaluate the efficacy of the two frequency settings on the other associated conditions that often coexist in patients with IC/PBS, such as female sexual dysfunction (FSD), bowel dysfunction, high tone pelvic floor dysfunction (HTPFD, painful spasm of the pelvic floor muscles), Vulvodynia (pain at the opening of the vagina).

Outcome Measures
Primary Outcomes (1)
Improvement in Urinary symptoms and Bladder pain/discomfort
To demonstrate better symptoms control (pain, urinary urgency and frequency) with sacral neuromodulation (SNM) in patients with interstitial cystitis /painful bladder syndrome (IC/PBS) using a stimulation frequency of 40 hertz (experimental) compared to a frequency of 14 hertz (standard).

Secondary Outcomes (1)
Improvement in Bowel symptoms and Sexual Function
1 year
Study Arms (2)
Interstim Parameter Frequency 14 HZ
ACTIVE COMPARATORSubjects in this arm will receive 14 Hx as their frequency for the first three months. For the second 3 months, these patients will receive 40 Hz. Six months after the devise has been implanted, the patient has the option to choose which frequency they feel allows for better symptom control, and this is how the devise will be programmed.
Interstim Parameter Frequency 40 HZ
EXPERIMENTALSubjects in this arm will receive 40 Hz as their frequency for the first three months. For the second 3 months, these patients will receive 14 Hz. Six months after the devise has been implanted, the patient has the option to choose which frequency they feel allows for better symptom control, and this is how the devise will be programmed.
Interventions
Subjects will be randomized into one of two groups. Group One will be programmed to receive 14 Hz as their frequency, while the other group (Group 2) will receive 40 Hz as their frequency for the first ninety days after surgical implantation. After three months each patient will come in to the office to have their InterStim frequency changed to the opposite frequency. After each patient has had three months to evaluate each of the two frequencies, the next step is to allow the patient to decide which setting they thought best controlled their respective symptoms. The InterStim was then programed to whichever frequency the patient chose, and this would remain for three to six months.
