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).

2. Secondary: 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).
