目的　评估Tru cut针活检、多谱勒超声检查 (CDFI)、同位素肾血流动态观察(SPECT)在肾移植术后的应用价值。方法　随机选择 30例肾移植患者 ,将单纯Tru cut针活检、CD FI以及SPECT检测所得结论作对比。结果　三种方式诊断准确率依次分别是 82 %、73 %、79%。结论　Tru cut针活检、CDFI和SPECT检查 ,均可作为肾移植术后的常规检测手段 ,三种方法联合使用 ,在临床上有较高的应用价值 Objective To evaluate the value of Tru cut needle biopsy, Doppler ultrasonography (CDFI) and dynamic isotope nephron flow (SPECT) after renal transplantation. Methods A total of 30 renal transplant recipients were randomly selected. The results of pure Tru cut needle biopsy, CD FI and SPECT were compared. Results The diagnostic accuracy of the three methods were 82%, 73% and 79% respectively. Conclusion Tru cut needle biopsy, CDFI and SPECT examination can be used as a routine test after renal transplantation, the combination of the three methods has a high clinical value
