The device, known as an orthopedic lithotriptor, is used for cases that have failed after six months of conventional therapy.
Lithotriptors direct high-energy shock waves into the body to disintegrate kidney stones into pieces as small as grains of sand without surgery.
Even with more than 20 years of engineering and design modifications, shock wave lithotriptors still have 5 basic elements:
These pediatric cystoscopes complement an entire family of adult urologic products, including flexible cystonephroscopes, rotating and slender resectoscopes, pneumatic lithotriptors, flexible ureteroscopes, percutaneous nephroscopes, and a variety of instrument accessories.
From lithotriptors that break down kidney stones to magnetic-resonance imaging machines, almost any medical service invented can be found in at least one of the region's 13 hospitals.
During the same period the first generation of lithotriptors appeared; these machines disintegrate kidney stones by means of shock waves applied from outside the body, usually without any surgery being necessary.
The lithotriptor was approved for widespread clinical use in the United States by the Food and Drug Administration in December 1984, at which time six experimental sites had lithotriptors (Bloom et al., 1989).
The use of ureteroscopic lithotripsy has become more intense.2,3 The increasing benefit, efficacy and success due to ureteroscopy and intra-corporal lithotripsy in time has been credited to the development of efficient and flexible ureteroscopes, laser lithotriptors, and various other accessories.4 Pneumatic lithotriptors which were first introduced into the market in 1990s are now most intensely used in such procedures in our country due to the fact that they are cost efficient.4
(3) The availability of smaller ureteroscopes and the development of intracorporeal lithotriptors such as the holmium:YAG laser are the most important technical advances improving the efficacy of ureteroscopic lithotripsy.
For ureteroscopic lithotripsy there is a variety of lithotriptors available including USG lithotriptors, electrohydraulic lithotriptors, electromechanical lithotriptors, laser lithotriptors, and the pneumatic lithotriptors.
