Interstitial cystitis: modern tools for an accurate diagnosis.

Interstitial cystitis (IC) is a disease defined by a constellation of signs and symptoms; its etiology is not well understood. There are multiple theories regarding the cause of IC; however, no one cause has been proven conclusively. In the meantime, physicians are trying to accurately diagnose a disease that has no identified definitive cause. There have been multiple tests designed to aid in the diagnosis of IC and there are new tests on the horizon that appear promising. However, the diagnosis of IC still is one of exclusion and based primarily on clinical findings. The most useful tests are described in this article, which may make diagnosis a more accurate, less arduous process.
