为了解肾脏疾病患者的肾功能情况，为临床治疗和预后判断提供依据，对８４例不同病期肾脏疾病患者和２２例正常对照者进行在９９ｍＴｃ－ＤＴＰＡ（二乙三胺五醋酸）肾动态显像，同时获得肾小球滤过率（ＧＦＲ）和肾功能曲线。结果表明，不同病期各组肾脏疾病患者的ＧＦＲ均明显低于正常对照组，且ＧＦＲ降低与病程和血清尿素氮、肌酐水平呈明显负相关。提示各组肾脏疾病患者的肾脏滤过功能均受损，其程度随病期的延长而加重。
In order to understand the renal function of patients with kidney disease, provide basis for clinical treatment and prognosis, 84 patients with different stages of kidney disease and 22 normal control subjects in 99mTc-DTPA (diethylenetriamine pentaacetic acid) Like, both glomerular filtration rate (GFR) and renal function curve. The results showed that the GFR of kidney disease patients in different stages was significantly lower than that of the normal control group, and the decrease of GFR was negatively correlated with the course of disease and serum urea nitrogen and creatinine. Tip renal disease in each group of patients with renal filtration function were impaired, the extent increased with the extension of the disease.
