OBJECTIVE
Hyperbaric oxygen therapy (HBO) has been successfully used in several disorders derived from tissue hypoxia, due to the extra oxygen supply to the tissues it enables. In this manuscript we performed a systematic review including all the existing data published until 2010 about HBO in urologic disorders.
METHODS
We performed a Medline search using the terms "hyperbaric oxygen", "radical cystitis", "interstitial cystitis", "hemorrhagic cystitis", "urological/pelvic fistula"and "Fournier's gangrene". The search was restricted to human clinical trials published in any language.
RESULTS
We found 56 papers: 1 randomized controlled trial, 7 reviews and 48 case reports; only one of them was a prospective study. A total of 695 patients were included. Just one study used tissue oxygen measurement to define hypoxia. The number of hyperbaric oxygen therapy sessions ranged from 4 to 44 (mean 19.2 sessions/patient).
CONCLUSIONS
The level of evidence from most reviewed papers is low because most of them are case series. Nevertheless, results of most of those studies regarding patient management are good or very good. So it seems that HBO can be very useful in urological diseases related to tissue hypoxia.
