Lithotripters, Intracorporeal, Laser

Definition : Intracorporeal lithotripters that use either a crystalline solid or an organic dye solution as their laser medium to produce coherent monochromatic light energy. The energy is delivered through an optical fiber, which is placed in contact with stones. The laser energy typically causes stone fragmentation in one of two ways: in some cases, the energy released when the laser is activated produces a plasma bubble that fragments the stone. In other cases, the laser energy is absorbed by the stone and causes the stone to vaporize and fragment. The stone fragments usually pass easily through the urinary tract. Stone fragments are sometimes removed using a stone basket or graspers.
