Computed tomography (CT) was performed in 50 patients before and after extracorporeal shock wave lithotripsy (ESWL) to determine the effects of ESWL on the kidney and perinephric tissues. Bilateral treatments were performed in three patients. Post-ESWL scans demonstrated subcapsular hematomas in eight (15%) patients (two large, six small, none symptomatic) and intrarenal hematomas in two (4%) patients. In three (6%) patients small subcapsular fluid collections of uncertain cause were seen. Treated kidneys showed a statistically significant mean increase in size (9%) after ESWL, as measured at the axial level of the major stone fragment. Perinephric soft-tissue stranding and fascial thickening were seen in 37 (70%) of 53 treated renal fossae, with the changes ranging from mild to severe. The authors conclude that while most patients undergoing ESWL will show some posttreatment abnormality on CT scans, the procedure appears to be associated with a low frequency of serious renal trauma.
对50例患者在体外冲击波碎石术（ESWL）前后进行了计算机断层扫描（CT），以确定ESWL对肾脏和肾周组织的影响。3例患者接受了双侧治疗。ESWL后的扫描显示，8例（15%）患者出现肾包膜下血肿（2例大血肿，6例小血肿，均无症状），2例（4%）患者出现肾内血肿。3例（6%）患者可见原因不明的小肾包膜下液体积聚。在主要结石碎片的轴向层面测量，治疗后的肾脏在ESWL后平均大小有统计学意义的增加（9%）。53个接受治疗的肾窝中有37个（70%）可见肾周软组织条索状影和筋膜增厚，变化程度从轻度到重度不等。作者得出结论，虽然大多数接受ESWL的患者在CT扫描上会显示一些治疗后的异常，但该手术似乎与严重肾创伤的发生率较低有关。
