Interstitial cystitis

Interstitial cystitis (IC) is a debilitating chronic inflammatory disorder of the bladder. It affects predominantly middle-aged Caucasian women. The diagnosis, made from the combination of symptoms, cystoscopic findings and bladder biopsies, is often delayed in the gynaecology setting because of a low index of suspicion. The pathophysiology is incompletely understood, although mast cell activation, altered bladder epithelial permeability and sensory afferent nerve up-regulation are thought to play key roles. Recent theories include the role of an antiproliferative factor. A wide assortment of therapies is available and many more are under trial. Until the causes and pathogenesis of IC are unraveled, mainstream medical treatment will remain palliative and cystectomy with urinary diversion, the only potential cure. In addition to our long experience on managing this disorder, we present a comprehensive review of the current thoughts on the aetiology and management of IC.
