EVIDENCE ACQUISITION pelvis and other urinary symptoms like urgency and The unrestricted, fully exploded Medical Subject frequency. Based on the evolving consensus that Heading (MeSH) ‘‘interstitial cystitis’’ (including all BPS probably is strongly related to other pain related terms as ‘‘painful bladder syndrome,’’ “bladder syndromes like Irritable Bowel Syndrome, Fibromyalgia pain syndrome”, or different terms such as ‘‘chronic and Chronic Fatigue Syndrome, the European Society interstitial cystitis,’’ etc.) were used to thoroughly for the Study of Bladder Pain Syndrome/ Interstitial search the PubMed database (http://www.ncbi. Cystitis (ESSIC) recently published a comprehensive nlm.nih.gov/PubMed/) of the US National Library of paper on definition and diagnosis of BPS [1]. Medicine of the National Institutes of Health; 1795 BPS was defined as chronic (>6 months) pelvic pain, hits were retrieved. After exclusion of uncommon pressure, or discomfort perceived to be related to the languages (other than English, French, German, urinary bladder accompanied by at least one other Italian, Japanese, Spanish, Swedish) and by limiting urinary symptom such as persistent urge to void or the publications to the time period January 2004 to May frequency. Confusable diseases as the cause of the 2008, 512 publications resulted. symptoms must be excluded. Further documentation Abstracts if available and titles of the 512 hits were and classification of BPS might be performed reviewed, focusing on (but not limited to) clinical trials, according to findings at cystoscopy with hydro- randomised controlled trials, meta-analyses, scientific distension and morphological findings in bladder guidelines, and core clinical journals. The literature biopsies.

In this categorizing levels of evidence is primarily relevant only chapter the term Bladder Pain Syndrome largely for the sections on treatment, which follow. While the replaces the older Interstitial Cystitis term, but committee’s opinions will be expressed, where the two are essentially interchangeable as there applicable, regarding evidence and conclusions for is no accepted definition that clearly delineates the other areas, including diagnosis, aetiology, and interstitial cystitis syndrome from bladder pain pathophysiology, use of the Oxford system in this syndrome. The Consultation believes the latter context is more open to interpretation. term more appropriately describes the disorder. 1461 Historically, definitions of IC have moved from a severe clear objective diagnostic criteria or pathophysiological inflammatory bladder disease to a condition described explanation, countless theories have been put forward primarily by symptoms (table 1) [2]. without adding much to the delineation or under- standing of the disease. The International Continence Society [9] (ICS) used the term Painful Bladder Syndrome (PBS) defined as In practice, patients with symptoms of BPS are “ the complaint of suprapubic pain related to bladder screened to exclude other relevant diagnoses or filling, accompanied by other symptoms such as confusable diseases [1], and a focused evaluation is increased daytime and night-time frequency, in the performed at the discretion of the physician or centre. absence of proven urinary infection or other obvious This evaluation might include cystoscopy under local pathology”.

One view of the relationship of chapter be referred to as BPS. As the terminology is BPS with OAB is graphically depicted in Figure 1 in flux, some of the older literature may be discussed [12].

The diagnosis of BPS is normal and the patients are identified as having BPS based on exclusion of other diseases in the bladder, as a diagnosis of exclusion. The relevance of urethra, and other pelvic organs including the urodynamic, cystoscopic and histological findings is musculoskeletal system.
