The setting is integral to the story and may sometimes become a character in itself. Characters: Local color stories tend to be concerned with the character of the district or region rather than with the individual: characters may become character types, sometimes quaint or stereotypical.
Lithotripsy is the use of high-energy shock waves to fragment and disintegrate kidney stones. The shock wave, created by using a high-voltage spark or an electromagnetic impulse outside of the body, is focused on the stone.The shock wave shatters the stone, allowing the fragments to pass through the urinary system.escription. Lithotripsy uses the technique of focused shock waves to fragment a stone in the kidney or the ureter. The affected person is placed in a tub of water or in contact with a water-filled cushion.
Laser lithotripsy was introduced in the 1980s. Pulsed dye lasers emit 504 nm light that is delivered to the stone by optical fibers through a scope. Holmium lasers were developed more recently and produce smaller fragments.
