New Approaches to Nerve Stimulation Therapy for Bladder Pain Syndrome

Study Summary

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 over the use of placebo? 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. Some participants will receive treatment, whereas others will receive sham (placebo). Participants will not be informed of their treatment group until the conclusion of the study. 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 compare treatment and sham groups to see if pain scores, as well as other secondary outcomes listed above, are different between these groups

Primary Outcome

The visual analog scale (VAS) is a validated, subjective measure for pain. Scores are recorded by making a mark at any number of defined intervals on a 10-cm line that represents a continuum between "no pain" (0) and "worst pain" (10). Scale from 0-10, with higher scores indicating worse outcome.
