Robert Moldwin, MD, director of the Pelvic Pain Center at the Arthur Smith Institute for Urology in New Hyde Park, NY, gives an overview of the definition of interstitial cystitis — severe and lasting inflammation of the bladder wall.

Dr. Moldwin discusses less obvious presentations of the problem, which he groups under the larger umbrella of Painful Bladder Syndrome, which does not necessarily include inflammation but always involves oversensitivity.
