To find the treatment process by extracorporeal shock wave lithotripsy(ESWL) and its related stone characteristics in urinary tract stone patients, an analysis was done from medical records of 331 cases who were treated by ESWL from December 2002 to March 2008 at H hospital in G city. The results are as follows : 1. Among 331 study subjects 68.6% were male and 31.4% were female. Their mean age(standard deviation, SD) was 44.2(13.9) years old and 84.0% lived in G city. 2. Average frequency of ESWL done toward study cases were 1.9±1.5 times. Mean duration of disappearance from pain was 3.2±2.1 days and total treatment period for a stone was 10.3±8.4 days. 3. Statistically significant(p<0.01) stone and urinary tract characteristics related with frequency of ESWL were stone size, radio-opacity, of the stone, and obstruction of urinary tract. The model composed of these 3 independent variables explained 13.5% of frequency of ESWL. 4. Statistically significant (p<0.01) variable related with disappearance from pain was radio-opacity of the stone, and this model explained 7.4% 5. Statistically significant(p<0.01) variables related with treatment duration due to stone were stone size and radio-opacity of the stone. These two variables explained 13.5% In conclusion, the bigger the size of stone are, the slower the treatment process will be. And when the stone is radio-opaque and urinary tract is obstructed, the treatment process will be slower than stone is radio-luscent and urinary tract is not obstructed. So to make effective and efficient treatment manual for ESWL, above fact must be considered and continuous systematic evaluation and research toward ESWL are necessary.
