β2-m易从肾小球滤出,但其中99%在近端肾小管被重吸收并进行分解。其合成与释放恒定,与性别、年龄及时间无关。故血、尿β2-m含量相对恒定,由此我们选择血清、尿液中β2-m含量的变化来观察体外震波碎石术(ESWL)对肾功能的影响。1资料和方法1·1一般资料总结分析2004年1月~2005 β2-m is easily filtered out of the glomeruli, 99% of which is reabsorbed in the proximal tubules and broken down. Its synthesis and release constant, regardless of gender, age and time. Therefore, blood, urine β2-m content is relatively constant, so we choose serum, urine β2-m content changes to observe the impact of extracorporeal shock wave lithotomy (ESWL) on renal function. 1 Materials and Methods 1.1 General Information Summary Analysis January 2004 ~ 2005
