The gallbladder lies at the junction of the medial segment of the left and right hepatic lobes. Besides the anatomic location, other factors may interfere with an ideal targeting of gallstones during extracorporeal shock waves treatment. Obesity, malnourishment, the respiratory cycle, the presence of intestinal gas, and colonic content may interfere with an adequate focalization. The use of a multipurpose device able to couple with the anterior abdominal wall like the Lithostar Plus permits to perform the procedure with the patient in supine, oblique or intercostal position. Varying the position permits to avoid interferences due to intestinal gas or intestinal content. The movements of the patients which produce a missing image can be easily refocussed. Technical ability, experience and a good machine permits a successful rate of gallstone fragmentation.
胆囊位于左右肝叶内侧段的交界处。除了解剖位置外，其他因素可能会在体外冲击波治疗期间干扰对胆结石的理想靶向定位。肥胖、营养不良、呼吸周期、肠道气体的存在以及结肠内容物可能会干扰充分的聚焦。使用像Lithostar Plus这样能够与前腹壁耦合的多功能设备，可以让患者在仰卧位、斜位或肋间位进行该操作。改变体位可以避免肠道气体或肠内容物造成的干扰。患者产生图像缺失的移动可以很容易地重新聚焦。技术能力、经验和良好的设备可实现胆结石破碎的成功率。
