摘要
目的探讨核素99mTc-DTPA肾动态显像评价重度肾积水患肾残余功能的临床价值。方法B超检查诊断为重度肾积水的患者29例(共30只患肾),应用核素99mTc-DTPA行肾动态显像,同期行静脉肾盂造影(IVP),比较这两种方法评价患肾残余功能的差异。结果(1)在30只受检患肾中,有12只患肾IVP和99mTc-DTPA肾动态显像均显示有残余功能,GFR为(22.32±3.55)ml/min;IVP不显影的患肾18只,其中8只99mTc-DTPA肾动态显像提示患肾有残余功能,GFR为(13.36±4.54)ml/min,剩余10只患肾99mTc-DTPA肾动态显像亦显示无残余功能。(2)99mTc-DTPA肾动态显像结果显示有残余功能肾脏多于IVP(P<0.05)。结论99mTc-DTPA肾动态显像用于评价重度肾积水患肾残余功能较IVP更为灵敏,且能定量分析肾小球滤过功能。
Objective To evaluate the clinical value of the radionuclide ^99mTc - DTPA renal dynamic imaging for measuring residual function of the kidney with severe hydronephrosis. Methods 29 patients（ a total of 30 hydrops kidneys） who had severe hydronephrosis diagnosed by B uhrasonography were compared with results obtained by ^99mTc - DTPA renal dynamic imaging and intravenous pyelography respectively. Results （ 1 ） Among 29 patients with 30 hydrops kidney, 12 hydrops kidneys had shown residual function with the IVP and ^99mTc - DTPA renal dynamic imaging, GFR was （22.32 ± 3.55 ） ml/min ; IVP showed negtive in 18 hydrops kidney, but ^99mTc - DTPA renal dynamic imaging showed positive in 8 cases, GFR was （13.36 ±4.54） ml/min,the otherl0 hydrops kidneys were showed no residual function by ^99mTc - DTPA renal dynamic imaging as well; （2） ^99mTc - DTPA renal dynamic imaging had significant difference compare with IVP in residual function test （ P 〈 0.05 ）. Conclusion ^99mTc - DTPA renal dynamic imaging is more sensitive than IVP in evaluating residual function of the kidney with severe hydronephrosis, and it also can measure GFR.
