摘要
目的:探讨应用非增强螺旋CT测定结石CT值对上尿路结石腔内碎石治疗效果的应用价值。方法:对256例结石大小在1.0～2.5 cm需行输尿管镜下或经皮肾镜下碎石的患者,在术前用非增强螺旋CT测定结石CT值。随机分成两组,一组用气压弹道碎石,一组用钬激光碎石。用统计学分析两组结石CT值、碎石成功率、碎石时间。结果:输尿管结石、肾结石的CT值<1 200 Hu时,两种碎石方法碎石时间、碎石成功率无明显差别(t=3.412,P>0.05)。输尿管结石、肾结石的CT值>1 200 Hu时,钬激光组较气压弹道组碎石时间明显减少,差异有统计学意义(t=4.904,P<0.01);钬激光组碎石成功率较气压弹道组高,差异有统计学意义(t=5.085,P<0.05)。但钬激光碎石效率也降低,碎石时间增加,须加大能量进行碎石。结论:在腔镜碎石前测定结石CT值有助于选择合适的碎石器,减少手术时间,增加碎石率,减少并发症的发生,有较大的临床应用价值。
Objective：To study the application value of noncontrast Helical CT （NCHCT） in treatment of intracavity lithotripsy for upper urinary calculi. Methods： A total of 256 cases of upper urinary calculi 1.0-2.5 cm in size, pretreatment NCHCT measuring the CT value, which divided them into two random groups of pneumatic lithotripsy group and holmium laser lithotripsy group. The relationship among the CT value, operation time, suc： cess rate were analyzed. Results：The CT value 〈1 200 Hu, the operation time and the success rate between the ureteral calculi and the kidney calculi was indiffienee （t=3. 412,P〉0.05）. The CT value〉1 200 Hu , holmium laser lithotripsy group was less than pneumatic lithotricopy group （t=4. 904, P〉0.01）. And the success rate of holmium laser lithotripsy group was significant higher than that of pneumatic lithotricopy group （t=5. 085, P〈 0.01）. But the efficiency of holmium laser lithotripsy was lower, and the time of lithotripsy was increased. It was required to increase energy for lithotripsy. Conclusions：The CT value on pretreatment NCHCT is useful to choose the equipment in treating upper urinary calculi. It can reduce the operative time, increase the rate of lithotripsy and reduce the incidence of complications, which has a greater clinical value
