Female bladder pain syndrome (FBPS), previously known as interstitial cystitis/bladder pain syndrome, is a life-altering and morbid condition that occurs primarily in female patients and can be variable in presentation. Given the absence of pathognomonic symptoms and sensitive diagnostic tests, significant symptomatic overlap with numerous other pelvic conditions (such as pelvic floor tension myalgia or endometriosis) occurring in women makes diagnosis of FBPS challenging. The frequent co-occurrence of FBPS with other pain conditions and functional somatic syndromes further complicates diagnosis and management. The challenges have limited the progress made in understanding the pathophysiology of the condition and improving approaches to treatment and prevention. Improvement in standardization of the terminology used to describe this unique condition is needed to improve the accuracy of diagnosis and the clinical care for affected patients. Given the variability in presentation and the differing definitions for the condition world-wide, the American Urogynecologic Society and the International Urogynecologic Association convened a joint writing group to standardize terminology around common signs and symptoms of the condition and to clarify the diagnosis as it pertains to female patients with the condition. After careful consideration of a broad range of available data and clinical experiences, consensus opinion recommended adopting the term "FBPS" instead of the misleading "interstitial cystitis" to describe a chronic, intermittent condition of at least 3 months' duration affecting women involving symptoms of pain or discomfort localized to the bladder, often with bladder filling, which are not attributed to other pathology. This term will allow clinicians, researchers, and learners alike to standardize their understanding of FBPS.
