Study Summary
In 2014, the American Urological Association updated it management algorithm for Interstitial Cystitis/Painful Bladder Syndrome (IC/PBS). As the algorithm progresses, interventions become increasingly invasive and morbid. 4th line treatment is sacral neuromodulation (SNM), involving a two stage surgical procedure and permanent device implantation. While the mechanism for decrease in IC/PBS symptoms is unknown, SNM is thought act through central and peripheral mechanisms related to afferent signaling, causing modification of pain and lower urinary tract sensation.¹ Percutaneous posterior tibial nerve stimulation (PTNS) is a method of peripheral neuromodulation targeting the same nerve roots as SNM, but with significantly fewer risks. The purpose of our research is to determine if PTNS is effective in the treatment of IC/PBS. The results of this study will suggest future directions and provide critical information to design studies to determine to what extent and in what situations PTNS may be effective. The investigators will enroll subjects with IC/PBS and urinary frequency/urgency to treatment with 12 weekly treatments of PTNS. The investigators will assess symptoms and lower urinary tract function before, during and after the treatments. At the completion of treatments, subjects will be asked to enroll in post-study follow up monitoring to understand the duration of symptom effect.
Primary Outcome
The primary outcome variable will be the percentage of subjects to report that they are moderately improved or markedly improved in overall symptoms compared to baseline on a 7-point global response assessment (GRA) scale. The GRA scale involves asking the question, "As compared to when you started the current study, how would you rate your overall symptoms now?". There are 7 possible responses: markedly worse, moderately worse, slightly worse, the same, slightly improved, moderately improved an
