The laser lithotripsy is not a surgical treatment, the laser was first used in industry, because it has a very good high energy, and has a very good focusing effect, medicine also used to deal with the stone, itself is not considered a treatment, but only a means. Need a very thin optical fiber, the laser generated by the laser generator outside the body to guide to the body to go, through the ureteroscope, nephroscope to establish a good channel, with the mirror close to the stone, and then use the laser against the stone to combat, because the laser has this high-energy and efficient characteristics, can be relatively large stones into small pieces, and even now there are higher energy laser can be completely powdered, the stone hit like a sky Snow flakes or haze like form, after breaking into very small stones, can help patients discharge. Compared with the former pneumatic ballistic lithotripsy, pneumatic ballistic lithotripsy may not be able to achieve this effect, pneumatic ballistic lithotripsy into a larger stone, the proportion of discharged stones is relatively small, and laser lithotripsy because of a variety of advantages, more and more in the clinical application of the very good social and economic results.
