Abstract:

A urinary tract diseases that are among the most serious diseases affecting humans, and is the third grade was stone disease between these diseases. Proved successful in many ways the treatment of this disease, but found that the most successful method is the use of shock waves in the treatment of this disease. Stone disease is the accumulation of ions and salts inside the urinary tract. The Extracorporeal Shock Wave Lithotripsy (ESWL) is the method of stones disintegration inside the kidney as well as the ureter by using sound waves with high pressure. The objective of this research is to find the numbers of shock waves that’s required to disintegrate stones inside the kidney and ureter by using a constant energy, the required shock waves for treating 1 cm3 of calcium oxalate monohydrate:3500 shocks, for Magnesium Ammonium Phosphate is 3600 shocks and to disintegrate Uric Acid stone is 3590 shocks. In the north of IRAQ: Arbil,Dohuk and Sulaimania around 60 patients had been accumulated, and comparing the number of the shocks had been used to solve each stone type of the three-type mention above. Through this research was to reach the young people more vulnerable to the disease, those who aged between 20 to 40 years, where the bodies of these young people a more interactive with the composition of the stones, as well as demonstrated to us that men are more vulnerable to infection than women. According to the results in the field has become visible that the stones that have been addressed successfully by the size ranged between 0.5 - 1 cm. Reflect the strategy we were able to calculate the number of shocks, the MATLAB program had been used.
