Broncholith removal using the YAG laser.

An 85-year-old woman presented with a broncholith in the intermediate bronchus that could not be extracted with either flexible or rigid bronchoscopes. A YAG laser was used to fragment this broncholith so that it could be removed in pieces through a bronchoscope. Chemical composition and morphology of the broncholith were determined. Fragmentation of the large, impacted broncholith with the laser eliminated the necessity for a thoracotomy in this elderly woman.
