Pilot study to determine feasibility for treating patients with two chronic inflammatory
conditions of the urinary bladder: chronic interstitial cystitis and recurrent urinary tract
infections using a standardized hyperbaric oxygen treatment plan. Presently there are no good
treatments for these conditions and hyperbaric oxygen may be a safe and readily accessible
therapy as it has proven successful an another type of chronic inflammatory condition of the
urinary bladder known as "radiation cystitis". The study will determine if patients will
consider this an acceptable treatment for their conditions and that it is well tolerated.
