Can Hyperbaric Oxygen Therapy (HOT) have a place in the treatment of some urological diseases.

HOT (Hyperbaric Oxygen Therapy) is used in urological diseases: Scrotal/perineal fasciitis and Radiation-induced cystitis (and proctopathy); in urgency and frequency syndrome and with chronic pelvic pain the use of HOT is still experimental. The basic principle of HOT is to increase oxygen dissolved in the blood when it is administered at high pressure. O2 is then distributed to the tissues through the pressure gradient; tissue hyper-oxygenation has anti-inflammatory and pain-killing effects, it increases bacterial permeability to antibiotics, strengthens neo-angiogenesis, reinforces lymphocytes and macrophages function, augments testosterone secretion (in males), and finally enhances wound healing process. We treated with HOT (integrating other treatments) 17 cases of necrotizing fasciitis, 13 radiation-induced cystitis and 4 cases of urgency and frequency syndrome. We always had good results, with a good cleansing of the dissected areas in Fournier's gangrene; in the cases of radiation-induced cystitis we had an improvement in the symptoms and hematuria, and finally in cases of urgency and frequency syndrome we had a transient reduction of symptomatology and pain. Our experiences and the specific literature on this subject suggest that HOT, sometimes associated with other medical and surgical therapies, can be an effective tool to treat urological diseases; in some cases its efficacy was well demonstrated (Fournier's gangrene and Radiation-induced cystitis), in others (urgency-frequency syndrome and chronic pelvic pain) it is a promising technique which definitely needs further research.
