What is interstitial cystitis (IC)/painful bladder syndrome (PBS)?

Interstitial cystitis (IC) is a term that has been used to refer to a clinical constellation of symptoms characterized by chronic urinary urgency (feeling the need to urinate immediately) and frequency (frequent urination), usually with suprapubic discomfort or pressure that usually is relieved by urinating. The symptoms of this condition vary among individuals and may even vary with time in the same individual. The term cystitis refers to any inflammation of the bladder. In contrast to bacterial cystitis that results from an infection in the bladder, a type of urinary tract infection (UTI), no infectious organism has been identified in people with interstitial cystitis. In 2006, the European Society for the Study of IC/BPS suggested the use of the term bladder pain syndrome (BPS) for these patients.

The American Urological Association (AUA) guidelines use the following definition for IC/BPS:

IC/BPS is an unpleasant sensation (pain, pressure, and discomfort) perceived to be related to the urinary bladder, associated with lower urinary tract symptoms of more than six weeks duration, in the absence of infection or other identifiable causes.

Estimates of the number of people affected by IC/PBS vary widely and are dependent upon the criteria used for diagnosis. Many experts believe that about 3.3 million women in the U.S. (over age 18) may be affected, as well as 1.6 million men.

Despite a lack of consistency about the diagnosis of IC/PBS, studies agree that the majority of those affected are women. While individuals of any age can be affected, including children, the average age of onset is around 40. IC/PBS has not been considered to be a hereditary disorder, but multiple cases have occurred among some families, prompting ongoing investigation of the possible role of hereditary factors in the development of IC/PBS.

Observations from cystoscopy (visual examination of the inside of the bladder via a camera) have found that two patterns exist for IC, ulcerative and nonulcerative, depending upon the presence or absence of ulcerations, breaks in the bladder lining. Star-shaped ulcerations in the bladder wall are known as Hunner's ulcers. These are found in less than 10% of cases of IC/PBS in the U.S.

Over time, interstitial cystitis can cause physical damage to the bladder wall. Scarring and stiffening of the bladder wall may occur as a result of the chronic inflammation, leading to a decrease in bladder capacity. Glomerulations (areas of pinpoint bleeding) and petechial hemorrhage may be seen on the bladder wall.
