摘要
目的运用彩色多普勒超声(CDU)观察经皮肾镜超声弹道气压碎石术治疗不同肾功能肾脏的血流动力学参数。方法应用CDU检测79例81个上尿路结石肾脏经皮肾镜超声弹道气压碎石术治疗前后血流动力学参数,并与治疗前后肾脏肾小球滤过率(GFR)差值比较,根据术前术后GFR变化将患肾分为四组,即肾无功能组(A组),肾功能明显改善组(B组),肾功能明显减退组(C组)及肾功能无明显改善组(D组)。对各组肾动脉血流动力学参数进行比较及相关分析。结果 A组肾叶间动脉(IRA)、肾段动脉(SRA)、肾主动脉(MRA)术前术后收缩期峰值流速(PSV)、舒张末期流速(EDV)、阻力指数(RI)与B、C、D组比较差异均有统计学意义(P<0.05)。B组IRA术前术后RI与A、C、D组比较差异均有统计学意义(P<0.05)。结论彩色多普勒超声评估肾功能,当IRA血流参数PSV<15.92cm/s、EDV<3.18cm/s、RI>0.8,SRA血流参数PSV<25.68cm/s、EDV<6.16cm/s、RI>0.76,MRA血流参数PSV<36.43cm/s、EDV<7.28cm/s、RI>0.8时,肾功能基本不能恢复。当IRA阻力指数RI<0.72时肾脏功能可明显改善。
Objective To evaluate the hemodynamics parameter of the different function kidney treating with Pereutaneous Nephrolithotripsy with Ultrasound Pneumatic Lithotripsy by using color doppler ultra- sonography （CDU）. Methods The investigation was divided the sick kidney into four groups according to the change of glomerular filtration rate （GFR）of the pre or post- operative, namely the nonfunctional kid- ney group（Group A）, significant improvement in the group of renal function（Group B）, significantly di- minishing group of renal function（Group C）, renal no significant improvement in the group（Group D） and to detect the hemodynamics parameter in 81 urinary tract stones kidney of 79 cases pre or post- operative treating with Percutaneous Nephrolithotripsy with Ultrasound Pneumatic Lithotripsy by CDU and to com- pare them with the difference between the kidney GFR. The hemodynamics parameter were compared by correlation analysis. Results Compared with the other three groups in peak systolic velocity（PSV）, end- diastolic velocity （EDV） and resistance index（RI） in the pre or post- objective, there were statistical difference in interlobar renal artery（IRA） , segment renal artery（SRA） and main renal artery （MRA） of Group A,P〈0.05. The IRA of the pre or post - objective in group B was significant different from other groups,P〈0.05. Conclusions The renal function nearly cannot regain when The PSV was less than 15.92 cm/s, EDV was less than 3.18 cm/s and RI was more than 0.76 in the hemodynamics parameter of IRA, the PSV was less than 25.68cm/s, EDV was less than 6.16cm/s, RI was more than 0.76 in the hemody- namics parameter of SRA, the PSV was less than 36.43 cm/s, EDV was less than 7.28 cm/s, RI was more than 0.8 in the hemodynam- ics parameter of MRA. The renal function may get better when The RI was less than 0.72 in the hemo- dynamics parameter of IRA.
