Objectives: To identify any potentially harmful chemical constituents of the gaseous plume produced from urological endoscopic diathermy.
Methods: Chemical analysis was performed on the gaseous plume produced from prostatic resections and vaporizations using gas chromatography with mass spectroscopy and high-performance liquid chromatography using ultraviolet and visible light detection. In addition, carbon monoxide levels were analyzed using a portable catalytic flammable gas sensor.
Results: This study identified a cocktail of volatile organic hydrocarbons produced during these procedures, some of which are known carcinogens. The most significant finding being high levels of carbon monoxide.
Conclusions: From this preliminary study, we advocate the use of smoke evacuator systems for all urologists regularly performing these procedures, and suggest that further research is required to investigate potential long-term complications to the urologist.
