对2007年8月至2009年1月采用CT引导经皮输尿管镜下钬激光碎石术治疗的32例患者临床资料进行分析.CT引导的定位时间、定位失败率、一次碎石清石率、并发症发生率及残石率,均优于X线(33例)及超声定位(30例),其中一次碎石清石率及并发症发生率差异有统计学意义(均P＜0.05).结果说明在肾脏位置较高、有周围脏器(如肝、脾、结肠、胸膜等)围绕者,鹿角状结石或大的肾盂肾盏结石而无肾积水者,合并肾先天畸形如肾旋转不良、重复肾以及超声或X线引导失败的情况下,适于选择CT引导下肾结石碎石治疗.

From August 2007 to January 2009 a total of 95 patients with complex renal calculi were treated with CT ( n = 32 ), X-ray ( n = 33 ) or ultrasound ( n = 30 ) guided percutaneous nephrostomy and ureteroscopic holmium laser lithotripsy respectively. The CT guided procedure had lower positioning time,positioning failure rate, complication rate and residual stone rate than those of X-ray and ultrasound localization, particularly had advantages in the stone clearance rate and complications rate ( all P ＜ 0. 05 ).CT guided localization can be chosen in the following conditions: higher kidney position, large staghorn calculi or renal pelvis stones without hydronephrosis, with congenital renal malformations or failure of ultrasound or X-ray localization.
