 note = {In Extracorporeal Shock Wave Litotripsy (ESWL), either B-mode echo or fluoroscopy is usually used for focusing on the stone and for monitoring. Although B-mode echo has good points of limited radiation exposure and of capability to moniter lithotripsy throughout the treatment, it has a shortcoming of less detectability of both stone and the degree of stone disintegration compared to fluoroscopy. The objecttive of this study was to examine whether it is possible to perform ESWL under color Doppler echo monitoring. Experimental study using model of stone provided the following results. Shock wave caused stone movement, which could be detected as color flow on color Doppler echo. Unfixed stone showed stronger and brighter color flow than fixed stone, and more highly disintegrated stone showed stronger color flow. Based on these findings, color Doppler echo guided ESWL was peformed on the 32 treatments in 22 patients. Among these treatments, coloring on the stone was found in 26 treatments. In cases with positive color flow, color Doppler echo could detect stone easier than B-mode echo by focusing the clearest coloring region. In some cases with difficulty in the detection of stone by B-mode echo, color Doppler echo showed good focusing on stone and good detectability of stone disintegration. In other cases, color flow did not change throughout treatment. Furthermore, the patterns of stone movement caused by shock wave are various. Therefore, optical conditions of color Doppler echo to detect detailed situation of stone disintegration should be examined, and the condition for each patient should be correctly chosen.},
