目的：探讨99mTc-EC肾动态显像在尿路感染患儿肾瘢痕诊断中的价值。方法回顾性分析同期行99mTc-EC肾动态显像和99mTc-DMSA肾静态显像的67例尿路感染患儿的显像资料，以99mTc-DMSA肾静态显像结果为金标准，分析比较99mTc-EC肾动态显像与尿路感染、肾积水与肾瘢痕的关系。结果99mTc-EC肾动态图起始2 min叠加图像诊断肾瘢痕的灵敏性是80.28%，特异性是88.89%，阳性似然比为7.23。采用99mTc-DMSA肾静态显像诊断肾瘢痕，发现与上尿路排泄通畅和排泄延缓的患儿相比，上尿路排泄梗阻患儿的肾瘢痕形成概率较高，差异有统计学意义（P<0.05）；但积水程度不同患儿的肾瘢痕发生概率的差异无统计学意义（P>0.05）。结论对尿路感染患儿，99mTc-EC肾动态显像早期叠加图像诊断肾瘢痕形成的灵敏性和特异性均较高，99mTc-EC肾动态显像提供的上尿路排泄情况对肾瘢痕形成的诊断具有一定价值。
目的：探討99mTc-EC腎動態顯像在尿路感染患兒腎瘢痕診斷中的價值。方法迴顧性分析同期行99mTc-EC腎動態顯像和99mTc-DMSA腎靜態顯像的67例尿路感染患兒的顯像資料，以99mTc-DMSA腎靜態顯像結果為金標準，分析比較99mTc-EC腎動態顯像與尿路感染、腎積水與腎瘢痕的關繫。結果99mTc-EC腎動態圖起始2 min疊加圖像診斷腎瘢痕的靈敏性是80.28%，特異性是88.89%，暘性似然比為7.23。採用99mTc-DMSA腎靜態顯像診斷腎瘢痕，髮現與上尿路排洩通暢和排洩延緩的患兒相比，上尿路排洩梗阻患兒的腎瘢痕形成概率較高，差異有統計學意義（P<0.05）；但積水程度不同患兒的腎瘢痕髮生概率的差異無統計學意義（P>0.05）。結論對尿路感染患兒，99mTc-EC腎動態顯像早期疊加圖像診斷腎瘢痕形成的靈敏性和特異性均較高，99mTc-EC腎動態顯像提供的上尿路排洩情況對腎瘢痕形成的診斷具有一定價值。

Objective To evaluate the diagnostic value of 99mTc-EC dynamic renography for renal scars in children with urinary tract infection. Methods The 99mTc-EC and 99mTc-DMSA renographic results of 67 children diagnosed with urinary tract infection were retrospectively studied. In comparison with 99mTc-DMSA cortical images, the value of 99mTc-EC dynamic renogra-phy for the diagnosis of urinary tract infection, hydronephrosis and renal scars was analyzed. Results The sensitivity and speci-ficity of the initial 2 minutes summed images in the 99mTc-EC images for the diagnosis of renal scars was 80.28%and 88.89%re-spectively, and the likelihood ratio was 7.23. Renal scars were more likely to be formed in patients with obstructed upper urinary tracts, as compared with patients with unobstructed upper urinary tracts and unsmooth upper urinary tracts (P<0.05). The inci-dence of renal scar formation was not significantly different among groups with hydronephrosis of varying degrees (P>0.05). Conclusions For children with urinary tract infection, the diagnostic sensitivity and specificity of the initial summed images of 99mTc-EC dynamic renography are high. Furthermore, the excretion of upper urinary tract showed by 99mTc-EC dynamic renogra-phy is valuable for the diagnosis of renal scars.
