Changes in intrarenal vascular resistance after extracorporeal shock wave lithotripsy (ESWL*) were studied with Doppler ultrasound techniques.
In 76 patients the resistive index was measured at an interlobar artery before and after ESWL in the treated and contralateral kidneys. The resistive index levels were compared to N-acetyl-beta-D-glucosaminidase levels in 40 patients.
We found an age-related positive linear correlation between post-therapeutic resistive index increases and patient age. N-acetyl-beta-D-glucosaminidase levels were also elevated after ESWL but these elevations were not age-related.
Elderly patients have a higher risk of post-ESWL renal tissue damage.
采用多普勒超声技术研究体外冲击波碎石术（ESWL*）后肾内血管阻力的变化。
对76例患者在ESWL治疗前后分别测量患侧和对侧肾脏叶间动脉的阻力指数。对40例患者的阻力指数水平与N-乙酰-β-D-氨基葡萄糖苷酶水平进行比较。
我们发现治疗后阻力指数升高与患者年龄呈年龄相关的正线性相关。ESWL后N-乙酰-β-D-氨基葡萄糖苷酶水平也升高，但这些升高与年龄无关。
老年患者ESWL后肾组织损伤风险更高。
