摘　　要：目的比较99mTc-DTPA肾动态显像和静脉肾盂造影(IVP)评价肾功能的价值。方法回顾性分析117例经临床症状、体征、B超、CT及生化检查等确诊为肾脏疾病患者的99mTc-DTPA肾动态显像和IVP检查资料。结果⑴在234只受检肾脏中,101只IVP提示肾功能良好,肾动态显像肾摄取均正常,GFR值为(60.13±16.85)ml/min;⑵48只患肾IVP提示显影不良,核素肾动态显像患肾摄取为1～3级,GFR值(23.06±10.61)ml/min;⑶、IVP不显影的患肾85只,71.8%(61/85只)肾动态显像提示有放射性摄取,GFR为(20.39±12.54)ml/min,其中,13.1%(8/61只)肾摄取正常(0级);⑷肾动态显像检出的有功能肾脏多于IVP(P<0.005)。结论99mTc-DTPA肾动态显像是评价肾功能的理想方法,优于IVP,IVP患肾不显影时应进一步行99mTc-DTPA肾动态显像。Objective To compare the value of 99m Tc-DTPA dynamic renal imaging and intravenous pyelography(IVP) in assessing renal function. Methods The results of 99m Tc-DTPA dynamic renal imaging and IVP in 117 patients with renal diseases confirmed by clinical examinations, abdominal ultrasonography, CT and blood biochemical markers were analysed retrospectively. Results Out of 234 kidneys,101 were clearly visualized by IVP, which were indicated normal renal uptake by 99m Tc-DTPA dynamic renal imaging, and the GFR value was (60.13±16.85)ml/min. 48 kidneys were poorly visualized by IVP, their uptake detected by dynamic renal imaging was between grade 1 to 3, and the GFR value was (23.06±10.61)ml/min. 85 kidneys were not visualized by IVP, 71.8% of which(61/85kidneys) were indicated uptake of radionuclide by dynamic renal imaging with the (20.39±12.54)ml/min GFR value, and uptake of 8 kidneys among the 61 kidneys was normal. The functional kidneys detected by dynamic renal imaging were more than those detected by IVP(P<0.005). Conclusion 99mTc-DTPA dynamic renal imaging is the ideal method for evaluation of renal function, is superior to IVP in assessing renal function, and should be performed on these kidneys not visualized by IVP.
