Abstract
INTRODUCTION: This review highlights NIDDK-funded clinical research studies focused on interstitial cystitis/bladder pain syndrome (IC/BPS) and chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). METHODS: Since 1987, the NIDDK has funded numerous cohort studies, epidemiologic studies, and clinical trials for these conditions. RESULTS: While the majority of clinical trials have not demonstrated positive results, these research efforts have provided essential information about these conditions, which have informed clinical practice guidelines and enhanced the clinical care of patients. CONCLUSIONS: The data from these studies are a valuable resource that is available via the NIDDK Data Repository for future analysis.
