糖尿病患者99mTc-DTPA肾动态显像的分析

为研究糖尿病患者在不同的病程中肾记显像的变化规律，从而为该病的诊断和治疗提供重要的依据，对４０例正常人和９８例糖尿病患者２７６个肾脏的＾９９ｍＴｃ－ＤＴＰＡ肾动态显像资料进行分析。按照病程长短将糖尿病患者分成病程≤１年、１－５年和≥５年３组。依据＾９９ｍＴｃ－ＤＴＰＡ肾动态显像等检查资料，将肾功能分成正常、大致正常、Ｉ度受损、Ⅱ度受损和Ⅲ度受损５级，以此进行资料统计和分析。结果表明，肾功能受损程度

An analysis of 99mTc-DTPA renal dynamic imaging in patientswith diabetes mellitus

To investigate the regularity of renal dynamic imaging in the various courses of diabetes mellitus, and then to provide the important evidence variety for diagnosis and treatment. The data of renal dynamic imaging was analyzed on 276 kidneys of 40 normal and 98 diabetic patients, and according to course of disease, the diabetic patients was divided into three groups: ≤1 year, 15 year and ≥5 year respectively. Based upon was grouped 99mTc-DTPA renal dynamic imaging and others, the renal functions into normal, approximately normal, Ⅰ, Ⅱ and Ⅲ injury respectively, and the statistics and analysis of these data were caried out. The extent of renal function injury was related to the course of diseace significantly, and it showed that the longer the course, the heavier the damage of renal function, and there was a significant difference between them (P<0.01). There was radioactive retention in pelvis and/or calyxes in 23.5% patients together with a stepwise curve on renogram. 99mTc-DTPA renal dynamic imaging can effectively evaluate the extent of renal functions injury and was also valuable for the clinical. Also, the study indicated that in diabetic patients susceptible to urinary tract infection could aggravate the injury of renal function.
