摘要
目的:探讨输尿管软镜碎石手术对肾脏血流动力学的影响。方法:收集输尿管软镜碎石术的单发肾结石患者61例,应用彩色多普勒超声(CDFI)观察记录术后1h内及术后7d术侧肾脏肾内动脉血流参数,并与术前1d结果对照,进行统计学分析。结果:与术前血流参数相比,术后1h内超声检查,术侧肾脏段动脉舒张末期流速(Vmin)测值减低、阻力指数(RI)测值增高(P<0.017),收缩期峰值流速(Vmax)测值无明显变化(P>0.017);术后7d复查,Vmin测值回升、RI测值降落(P<0.017),Vmax、Vmin及RI与术前测值相比无统计学差异(P>0.017)。结论:单发肾结石患者输尿管软镜碎石手术后会出现术侧肾脏短期、可逆性的肾段动脉Vmin减低、RI增高,CDFI可以量化评价输尿管软镜碎石术围手术期肾内血流动力学的改变。
Objective:To evaluate the effects of flexible ureteroscope lithotripsy by color doppler ultrasonography(CDFI)at segmental renal arteries.Methods:The hemodynamic of operated renal arteries of 61 patients with renal calculi who underwent unilateral flexible ureteroscope lithotripsy were examined separately preoperative and postoperative(1 hour and Day 7)by CDFI.Parameters were analyzed statistically.Results:In 1 hour after operation,a statistically significant in decrease of diastolic flow(Vmin)and increase of resistance index(RI)at segmental renal arteries were found compared with preoperative(P<0.017).In the follow-up measurement of 7 days after operation,the differences disappeared(P>0.017).Conclusion:CDFI can be used to observe the blood perfusion in kidney after flexible ureteroscope lithotripsy,and quantitaty the information of renal hemodynamics simply and rapidly.Renal Vmin decreased and RI increased can be found at postoperative in short-term,and the changes were reversible.
