肾结核患者99-mTCDTPA肾动态显像特征分析

目的 观察肾结核患者_99-mTC-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20-min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_99-mTC-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。

Analysis of the 99mTC-DTPA renal dynamic scintigraphy characteristics of the patients with renal tuberculosis

Objective To investigate the ^99 mTC-DTPA kidney dynamic scintigraphy of patients with renal tuberculosis and to analyze the changes of kidney function in different stages of renal tuberculosis.Methods Classify the renal function curve（Level 0～5）,analyze GFR,peak time,half-time and 20 minutes remaining row of data changes of these levels,and account the ipsilateral and contralateral kidney renal function curve classification.Results The renal function curve classification is related to the GFR（0 and 5,P=0.001）,the renal function with a higher kidney function will be seriously damaged.GFR will decrease significantly and affects the contralateral kidney.When the ipsilateral renal function curve is above level 3,the contralateral level 1 and 2 will account for 42% and level 3 will account for 25%.Conclusion To evaluate the current situation of the patient＇s kidney function,the renal dynamic scintigraphy will be more sensitive and effective than other imaging methods.
