Increasing experience with percutaneous nephrolithotomy has fostered an aggressive approach to most renal calculi. We report a case of a stone in a horseshoe kidney. Computerized tomography before anticipated percutaneous stone extraction revealed the colon to be positioned posterior to the left portion of the horseshoe kidney. The posterior position of the colon prevented percutaneous access to the kidney. Computerized tomography should be performed in patients with stones in horseshoe kidneys and other fusion anomalies before elective percutaneous stone extraction is done.
经皮肾镜取石术经验的不断增加促使人们对大多数肾结石采取积极的治疗方法。我们报告一例马蹄肾结石病例。在预期进行经皮取石术前的计算机断层扫描显示，结肠位于马蹄肾左部后方。结肠的后置位置阻碍了经皮进入肾脏。对于马蹄肾及其他融合异常且有结石的患者，在择期经皮取石术前应进行计算机断层扫描。
