Abstract: 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 .
