Abstract
Lithotripsy is been one of the most new medical technology evolutionized medical practice. Initially the indication of ESWL was united to a single stone 10mm. The successful treatment at that time las produced rapid technical advances in machine design. These technical advances, gaining experience and approval of the safety of the procedure, extends the range of indication to include most off uirinary stones. Therefore, extensive experiment and clinical studies were done since the early use of ESWL and up till now to evaluate its beneficial effects versus its morbidity to identify the possible factors which may influence the severity and consequence the tissue damage induced by ESWL. These studies still have been inconclusive in their reliability to confirm or deny the overall safe of ESWL. During the period from September 1995 to September 1996, 147 patients with kidney and ureteral stones were treated by ESWL using Siemens Lithostar 2 plus machine. The age of patient range from 7 & 72 year with an average 39.8 year. There were 88 males (59.8%) and 59 females (40.2%). There were unilateral stones in 140 patients (98.2%) and bilateral stones in 7 patients (1.8%) so the total number of uretero-ial unit was treated was 154 unit. Right-sided stones were found in 83 uretero-renal unit (58.8%) and ft sided in 71 uretero-renal unit (46.2%). One Hundred Eighteen patients had kidney stones (77.5%), 27 of had multiple kidney stones while 36 patients (22.5%) had ureteral es. 9 patients had radiolucent stone while the other had radiopaque ines.
