Clinical Efficacy of Changing the InterStim® Parameters in Patients With Interstitial Cystitis/Painful Bladder Syndrome

• Status: Unknown
• Phase: Phase 4
• Study type: Interventional
• Enrollment: 72 (estimated)
• Sponsor: Pelvic and Sexual Health Institute · Academic / Other
• Sex: Female
• Age: 18 Years – 70 Years
• Healthy volunteers: Not accepted

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).

Detailed description

Purpose: 1. Primary: 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. 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).

Conditions

• Painful Bladder Syndrome
• Interstitial Cystitis
• Pelvic Floor; Insufficiency
• Bowel Dysfunction
• Sexual Dysfunction
• Pelvic Floor; Incompetency

Interventions

Type	Name	Description
OTHER	Changing the Interstim parameter of '' Frequency" in patients with Interstitial Cystitis	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.
