目的观察肾结核患者99mTC-DTPA肾动态显像,分析肾结核不同阶段肾功能的改变情况。方法对肾功能曲线进行分级(0～5级),分析各级间的各指标肾小球滤过率(GFR)、峰值时间、半排时间和20min残留率的数据变化,并统计患侧和对侧肾的肾功能曲线的级别。结果肾功能曲线分级和GFR相关(0级和5级间P=0.001),肾功能曲线级别高的肾功能损坏严重,GFR显著降低;且患侧对对侧肾有影响,患侧肾功能曲线3级以上时,对侧1、2级的占42%,3级占25%。结论应用99mTC-DTPA肾动态显像的方法来评价肾结核患者肾功能的现状,有较大价值。
Objective To observe the 99mTC-DTPA renal dynamic imaging in patients with renal tuberculosis and analyze the changes of renal function in different stages of renal tuberculosis. Methods The renal function curves were graded (0 ~ 5), and the data of glomerular filtration rate (GFR), peak time, half-row time and residual rate of 20min were analyzed. Contralateral kidney renal function curve level. Results The renal function curve was correlated with GFR grade (P = 0.001 for grade 0 and grade 5), severe renal dysfunction was found in renal function curve and GFR was significantly decreased. The ipsilateral affected the contralateral kidney and the ipsilateral renal function curve When level 3 or above, 42% of the opponent’s 1,2-level and 25% of the third-level. Conclusion 99mTC-DTPA renal dynamic imaging method to evaluate the status of renal function in patients with renal tuberculosis, have great value.
