Chronic interstitial cystitis. Successful treatment with intravesical idocaine.

A case of interstitial cystitis in a patient with a 5-year history treated by intravesical instillations of Lidocaine is reported. The repeated treatment relieved the patient from her pain and induced a potent anti-inflammatory effect on the bladder wall. The concentrations of plasma Lidocaine were between 1.4 and 1.1 mg/ml. No adverse reactions were reported with a follow-up of 2-years.
