We report the results of 7 patients with calculi in a horseshoe kidney treated by extracorporeal shock wave lithotripsy (ESWL, 9 renal units) and percutaneous nephrolithotripsy (3 renal units) during a 3-year period. In the ESWL only group complete stone clearance was achieved in only 3 patients (50%) after an average of 3 sessions of therapy. On the other hand, complete stone clearance was achieved by percutaneous nephrolithotripsy with minimal complications. The poorer results with ESWL were due to difficulty in ultrasonographic localization of stones as well as poor drainage in these abnormal kidneys. Our experience with the Edap LT01 and the Sonolith 2000 lithotriptors suggests that while reasonable results are possible, treatment probably will require multiple sessions and the eventual outcome is less predictable than in normal kidneys. In contrast, the treatment of complicated stones in a horseshoe kidney presents no additional difficulty.
我们报告了7例马蹄肾结石患者在3年期间接受体外冲击波碎石术（ESWL，9个肾单位）和经皮肾镜碎石术（3个肾单位）治疗的结果。在仅接受ESWL治疗的组中，平均3次治疗后仅3例患者（50%）实现了结石完全清除。另一方面，经皮肾镜碎石术实现了结石完全清除，且并发症极少。ESWL效果较差的原因是结石的超声定位困难以及这些异常肾脏的引流不畅。我们使用Edap LT01和Sonolith 2000碎石机的经验表明，虽然可能取得合理的结果，但治疗可能需要多次进行，而且最终结果比正常肾脏更难预测。相比之下，马蹄肾复杂结石的治疗没有额外的困难。
