Abstract Purpose:To investigate the effect of ESWL on renal calyceal stones.Methods:We retrospectively studied 244 patients with renal calyceal stones (57 with upper calyceal stones,18 with middle calyceal stones,and 169 with lower calyceal stones) treated by ESWL.All patients were followed up radiographically at 1 month and every 6 to 12 months after ESWL.Results:The stone free rates of upper,middle and lower calyceal stones were 73.7%,61.1% and 78.7% respectively.Conclusions:ESWL is the treatment of choice for renal lower calyceal stones.

1.1 临床资料
本组244例中,男145例,女99例。年龄12~75岁。左侧109例,右侧125例,双侧10例。结石位于肾上盏57例,肾中盏18例,肾下盏169例。肾上盏结石直径0.4~2.0 cm,其中<1.0 cm 32例,1.0~1.5 cm 21例,1.6~2.0 cm 4例;肾中盏结石直径0.4~1.5 cm,其中<1.0 cm 9例,1.0~1.5 cm 9例;肾下盏结石直径0.4~2.2 cm,其中<1.0 cm 70例,1.0~1.5 cm 76例,1.6~2.0 cm 16例,>2.0 cm 7例。
1.2 治疗方法
JT-Ⅱ型碎石机X线定位或WD-ESWL-91型机B超定位碎石,工作电压7~11 kV,冲击次数2 000~3 600,ESWL后1~3 d摄X线腹部平片复查,对>0.4 cm残余结石再次行ESWL,并在最后一次行ESWL后1个月及每6~12个月进行X线腹部平片或肾脏B超复查,根据ESWL后1个月X线检查或肾脏B超检查结果,分为无结石和有残余结石两类,对后者再进行长期随访,并将结果分为残石消失、残石减少、残石不变及残石增加4种。
