摘　　要：目的探讨;^(99)Tc^(m)-MDP全身骨显像中肾脏异常浓聚的原因。方法统计我院2019年10月至2020年12月行全身骨显像检查的患者,收集其中肾脏异常浓聚病例,对该现象与可能原因进行关联性分析。结果2019年10月至2020年12月行全身骨显像722例,48例出现肾脏异常浓聚,发生率为6.6%,其中局灶性浓聚9例,超声学检查7例为尿路梗阻、2例正常,尿路梗阻致局灶性浓聚的比例77.8%;未见肾脏浓聚674例,其中化疗后21 d内227例,多于21 d或未化疗447例;双肾弥漫性浓聚39例,其中化疗后21 d内22例,多于21 d或未化疗17例,经χ^(2)检验:差异有统计学意义(χ^(2)=8.382,P<0.05)。结论;^(99)Tc^(m)-MDP全身骨显像中肾脏局灶性异常浓聚可能与尿路梗阻有关,而近期化疗后反应可能是双肾弥漫性浓聚的原因之一。Objective To recognize the reason of increased kidney sign on;^(99)Tc^(m)-MDP whole-body bone scan.Method Patients who received WBS between October 2019 and December 2020 were screened. The cases with increased kidney sign were collected,which conducting relevance analysis with the possible reason. Results We screened 722 exams,and 48(6.6%) patients exhibited increased kidney scan.There were 9 cases exhibited focal increased images that 7(77.8%,7/9)were urinary tract obstruction cases by ultrasonic examination and 2 were normal.There were 674 cases that had no increased kidney sign, of which 227 patients had chemotherapy with in 21 days,the rest had chemotherapy over 21 days or never chemotherapy. Among these patients with bilateral diffuse increased kidney sign,22 patients underwent chemotherapy with in 21 days. The number of the patients undergoing chemotherapy over 21 days or never chemotherapy was 17 cases. The statistical result showed χ^(2)=8.382,P<0.05. Conclusion The focal increased kidney sign was possible related with urinary tract obstruction,and recent chemotherapy was one of the possible reasons of bilateral diffuse increased kidney sign.
