目的:通过99mTc-DTPA肾动态显像,对糖尿病患者肾功能进行判断。方法:将104例不同病期肾脏疾病的老年患者根据其24h尿蛋白排泄率(UAER)分为DN0,1,2三组,获得三组的肾小球滤过率(GFR)后,力求找出两者之间的关系,并从理论上探讨两者之间的关系。结果:DN1组和DN2组患者与DN0组比较尿蛋白排泄率均有差异,但是DN0组与DN1组间比较,GFR没有显著差异。结论:使用99mTc-DTPA肾动态显像测定GFR无论对NIDDN患者肾功能受损的早期诊断还是了解肾功能受损程度均有重要的临床价值。此外,99mTc-DTPA肾动态显像法尚可获得分肾的血流灌注图、肾功能图及肾动态的形态学变化等资料,可获得更多的有关信息。
Objective: To determine the renal function of diabetic patients by 99mTc-DTPA renal dynamic imaging. Methods: A total of 104 elderly patients with different stages of kidney disease were divided into three groups according to their 24-hour urinary protein excretion rate (UAER): DN0, 1 and 2, and after obtaining the glomerular filtration rate (GFR) of the three groups, The relationship between the two, and theoretically explore the relationship between the two. Results: Urine protein excretion rate was significantly different between DN1 group and DN2 group compared with DN0 group, but no significant difference was found between DN0 group and DN1 group. CONCLUSIONS: The use of 99mTc-DTPA renal dynamic imaging in the determination of GFR has important clinical value both in the early diagnosis of impaired renal function and in the extent of impaired renal function in patients with NIDDN. In addition, 99mTc-DTPA renal dynamic imaging method is still available to divide the renal perfusion map, renal function chart and renal dynamic morphological changes and other information, get more information.
