New Approaches to Nerve Stimulation Therapy for Bladder Pain Syndrome
What this study is about
Many women suffer from bladder pain syndrome (BPS). There are many treatments, but there is no one universally effective option. The goal of this clinical trial is to explore the use of electrical energy directed towards a group of nerves, called the superior hypogastric plexus, for treatment of BPS in women over the age of 18 with a diagnosis of BPS.

Many women suffer from bladder pain syndrome (BPS). There are many treatments, but there is no one universally effective option. The goal of this clinical trial is to explore the use of electrical energy directed towards a group of nerves, called the superior hypogastric plexus, for treatment of BPS in women over the age of 18 with a diagnosis of BPS. The main question it aims to answer is: does use of electrical micro-current directed at the superior hypogastric plexus improve pain associated with BPS? There is data from many different studies that suggest that this kind of therapy might provide relief of BPS symptoms. Participants will be asked to participate for a total of six months from the date of their first nerve treatment. At the first appointment, they will be evaluated in the Walter Reed Chronic Pain clinic and asked several questions about the severity and personal management of their symptoms. The procedure will then be performed by inserting two needles into the back (one on either side of the spine) and directing extremely short bursts of electrical micro-current towards the target nerve. The medical term for this is "pulsed radiofrequency ablation." This procedure causes disruption on a microscopic level of nerve fibers that send pain sensations to the bladder and other organs in the pelvis. Following this initial appointment, participants will be asked about their symptoms at 1-, 3-, and 6-month follow-up appointments. Participants will be asked about pain, mood symptoms, sexual function, and measures of bladder irritation. The procedure will only be performed once. At the study conclusion, researchers will analyze pain scores, as well as other secondary outcomes listed above. Benefits of this study may include possible relief of BPS symptoms. This may help to advance research about treatments for BPS. This is a novel approach to the treatment of BPS and as such may provide benefits greater than those found in treatment outside of the study.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
