I devloped radiaton cystitis 5 years following IMRT & HDR, with blood in my urine and several blockages due to clotting. I was able to find a wound care clinic with Hyperbaric Oxygen treatment (HBOT) available nearby and was able to start HBOT approximately 6 weeks after onset of bleeding.
After 10 sessions my bleeding stopped. I went on to complete a full regimen of 60 treatment sessions and have had no bleeding in the 9 months since treatment.
My research indicated that HBOT treatments are most effective if begun relatively soon after onset of symptoms, so I'm very greatful I could find the treatment available so quickly.
It seems like this kind of treatment may be suited to radiation proctitis as well. I found it interesting that neither my oncologist and my urologist would not make a direct recommendation for HBOT, however, I was able to convince my urologist to include a statement that I could consider HBOT as treatment.
