摘要目的 探讨马蹄肾结石行体外冲击波碎石术(ESWL)的临床疗效.方法 回顾性分析1987年3月至2015年1月收治的42例马蹄肾结石患者的临床资料,男33例,女9例.年龄19～71岁,平均42岁.左肾盂结石25例,右肾盂结石17例.结石直径0.4 ～3.7 cm,平均1.8 cm.42例均行ESWL治疗,治疗频率2000～2700次,平均2500次;治疗电压4～7 kV;碎石时间30 ～ 45 min,平均35 min.术后均采用俯卧位体位排石.结果 本组42例,ESWL治疗1、2、3、4次完全排出结石者分别为29、8、3、2例.碎石后首次排出结石时间3～10d.结石直径＜1 cm者29例,25例治疗1次、4例治疗2次结石完全排出.结石直径1 ～2 cm者10例,4例治疗1次、4例治疗2次、2例治疗3次结石完全排出.结石直径＞2 cm者3例,1例治疗3次、2例治疗4次结石完全排出.患者术中及术后无特殊不适,术后40例出现血尿,未做处理,1～3d后血尿症状消失.7例于术后1～3d出现肾绞痛,口服止痛药后症状减轻.结论 ESWL治疗马蹄肾结石安全、简便,术后采用俯卧位体位更利于结石排出.

abstractsObjective To explore the clinical effect of extracorporeal shock wave lithotripsy (ESWL) for the treatment of horseshoe kidney stones.Methods A total of 42 cases of horseshoe kidney stones from March 1987 to January 2015 were enrolled.Among them,33 cases were male and 9 cases were female.Their age range was 19 to 71 years,average age was 42 years old.25 cases got left renal pelvis stone,17 cases were on the right renal pelvis side.The diameter range of stone was 0.4-3.7 cm,the average was 1.8cm.ESWL was applied to treat whole group.The prone position was used to removing calculus.The frequency of treatment was 2000-2700 times,with an average of 2500 times;the treatment voltage was 4-7KV.The gravel time of the treatment was 30-45min,the average was 35min.Results One time for ESWL was 29 cases,two times for ESWL was 8 cases,three times for ESWL was 3 cases,four times for ESWL was 2 cases.The first discharge stones time was 3 to 10 days.There was no special discomfort after operation.40 cases got hematuria after operation,which occurred in 1 to 3 days after ESWL Renal colic was in 7 cases which happened on 1-3 days after ESWL.Condusions Calculi in horseshoe kidney may be treated by ESWL.It is a safe and simple operation.The prone position may bring satisfactory effect.
