目的：探讨微创经皮肾镜钬激光联合气压弹道碎石术治疗马蹄肾结石的可行性与效果，以期指导临床诊治。方法：回顾性分析在2010 年8 月~2013 年8 月期间接受微创经皮肾镜钬激光联合气压弹道碎石术治疗的12 例马蹄肾结石患者的疗效及并发症。结果：在12 例患者中，一期结石清除率为83.3%(10/12)，2 例需要二期取石。单通道取石11 例，双通道取石1 例。1 例患者为上盏通道，其余患者均为中盏通道。平均手术时间105 min，术中平均出血量50 mL，平均住院天数14d。未出现严重并发症，无患者需要输血。结论：微创经皮肾镜钬激光联合气压弹道碎石术是治疗马蹄肾结石的安全、有效的方法，具有损伤小、出血少、恢复快等优点。

英文摘要:

Objective:To evaluate the clinical indications and efficacy of minimally invasive pereutaneous nephrolithotomy (pneumatic lithotripsy and Hohnium: YAG laser lithotripsy) in treating calculi within horseshoe kidneys and guide the clinical diagnosis and treatment.Methods:We retrospectively reviewed the outcome and complications of 12 patients received minimally invasive pereutaneous nephrolithotomy (MPCNL) in our center from August 2010 to August 2013. FromAugust 2010 to August 2013, a total of 12 patients received minimally invasive pereutaneous nephrolithotomy (MPCNL) in our center.Results:Of the 12 cases，83.3％ (10/12) were rendered stone free at 1 session. A second-look was needed in 2 cases. 11 cases were managed with a single tract, 2 tracts in one case．Renal access was obtained through an upper calyx in 1 case, a middle calyx in 11. Average operative time was 105 munites，blood loss volume was 50 mL, and the average hospitalization stay was 14 days. No major complications were noted and no blood transfusions were needed in all cases.Conclusion:Minimally invasive percutaneous nephrolithotomy (pneumatic lithotripsy and Hohnium: YAG laser lithotripsy) is safe and effective in treating calculi within horseshoe kidney, with a mini-invasion, less blood loss, and a short convalescence period.
