微创经皮肾镜取石术治疗孤立肾结石的疗效分析

目的 探讨微创经皮肾取石术(MPCNL)治疗孤立肾结石的临床疗效.方法 2000年8月至2010年8月,242例孤立肾结石患者接受MPCNL治疗.GFR 17～108 ml/min.SCr(108±20)μmol/L,高于正常者19例,平均(181±32)μmol/L.结石位于左侧116例,右侧126例,合并输尿管结石15例.结石大小1.1 cm× 1.8 cm～3.9 cm×5.8 cm. 结果平均手术时间68 min.一期结石清除率79.3%(192/242),残留结石≤4 mm者16例,残留结石5～19 mm者34例.二期MPCNL及ESWL术后1个月复查,结石总清除率88.0%(213/242).术后发热18例,输血21例,因术后严重出血行肾动脉造影及肾出血动脉超选择栓塞治疗10例,肾周血肿1例,气胸1例. 结论 MPCNL治疗孤立肾结石创伤小、并发症少、结石清除率高,应作为孤立肾结石患者的首选治疗方案之一.

Abstract：

Objective To report our experience with minimally invasive percutaneous nephrolithotomy (MPCNL) in treatment of renal calculi in solitary kidneys. Methods From August 2000 to August 2010, 242 patients with renal calculi in solitary kidneys were treated by MPCNL, the data were reviewed retrospectively. Results The mean operative time was 68 min, the clearance rates were 79.3% (192/242) after first session and 88. 0% (213/242) after second-look MPCNL and ESWL, respectively. Postoperative fever happened in 18 cases. Twenty-one cases required transfusion, 10 cases received angiography and embolization. One case experienced perirenal hematoma and 1 case had pneumatothorax. Conclusions MPCNL has the advantages of less bleeding, high clearance rate and short hospital stay. MPCNL is an effective and feasible treatment option for renal calculi in solitary kidneys and should be the first line choice.
