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).

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Interstim Parameter Frequency 40 HZExperimental Treatment1 Intervention
Subjects 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.
Group II: Interstim Parameter Frequency 14 HZActive Control1 Intervention
Subjects 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.
