Extracorporeal shock wave lithotripsy (ESWL) using YACHIYODA SZI was performed on 12 patients with renal stones and the effect on the kidney and adjacent tissue was evaluated by magnetic resonance imaging (MRI) before and after treatment. Some changes were seen in 6 of the 12(50%) patients; perirenal fluid collection in 2 of the 12 (16.7%) patients, subcapsular hematoma in 2 of the 12 (16.7%) patients, renal enlargement in 5 of the 12 (31.3%) patients, increased signal intensity in perirenal tissue in 6 of the 12 (50%) patients, and loss of the corticomedullary junction 2 out of 9 patients (22%). These findings indicated fewer changes in the kidney after ESWL using YACHIYODA SZI than in the other reports. MRI is also concluded to be effective to detect the changes of the kidney after ESWL.
对12例肾结石患者使用八田SZI进行体外冲击波碎石术（ESWL），并在治疗前后通过磁共振成像（MRI）评估其对肾脏及邻近组织的影响。12例患者中有6例（50%）出现了一些变化；12例患者中有2例（16.7%）出现肾周积液，12例患者中有2例（16.7%）出现肾包膜下血肿，12例患者中有5例（31.3%）出现肾脏增大，12例患者中有6例（50%）肾周组织信号强度增加，9例患者中有2例（22%）出现皮髓质交界消失。这些结果表明，与其他报告相比，使用八田SZI进行ESWL后肾脏出现的变化较少。还得出结论，MRI对于检测ESWL后肾脏变化是有效的。
