摘　　要：目的：探讨静脉注射小剂量呋塞米提高 CTU 中正常上尿路显影质量的价值。方法共39例，均行5 min 延迟扫描，其中19例扫描前静脉推注10 mg 呋塞米。对2组中上尿路每段显影连续性给予评分（0~4分），测量输尿管各段的短径最宽及最窄处取平均值，测量上尿路各段的 CT 值，结果行均数 t 检验。结果与对照组对比，呋塞米组有30/38个上尿路全部或几乎全部显影，除肾盂外其余各段的上尿路显影连续性显著提高；输尿管各段的扩张度均显著提高；上尿路各段的 CT 值均显著降低。结论在多排螺旋 CT 泌尿系统造影（MDCTU）中静脉注射小剂量呋塞米对正常上尿路的显影质量明显提高。Objective To explore the value of intravenous low dose furosemide on visualization of upper urinary tract during CTU. Methods 39 cases of normal upper urinary samples were examined by CTU with 5 minutes delayed,19 cases underwent intravenous injection of furosemide.The upper urinary tract was divided into 5 parts for scoring of images on a 5 score scales for opacification,the average value of ureter short axis of distention,and CT value by contrast material were measured.Results were analyzed by t test using SPSS.Results （1）30/38 segments of upper urinary tract were all or almost all opacification in furosemide group,the scores of upper urinary tract were higher than that of the control group,which had significant difference except the pelvis and left proximal ureter segments. （2）The disention of the ureter was significantly higher for all segments in furosemide group.（3）CT values in furosemide group decreased significantly for all upper urinary tract.Conclusion CTU excretory phase image acquisition with intravenous low dose furosemide is helpful on visualization of upper urinary tract.
