Abstract:
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.
