目的:探讨低张动态静脉尿路造影的检查方法。方法:从术前准备、造影方法、摄影技术及观察方法等方面进行探讨,并与CT扫描进行对照。结果:对206例泌尿系患者进行低张动态静脉尿路造影检查结果进行分析,显影满意79.6%(164/206),较好的16.9%(35/206),不满意的3.5%(7/206),其中70例延时1 h不显影,经CT扫描证实肾皮质变薄,经延时4~24 h不等后63例显影满意。结论:低张动态静脉尿路造影可提高尿路造影的显影率,了解肾脏的功能性和器质性病变,是诊断泌尿系疾患可靠的检查方法。
Objective: To investigate the method of low dynamic venous urography. Methods: From preoperative preparation, contrast method, photography and observation methods and other aspects of exploration, and with CT scan control. Results: Low-dynamic venous urography was performed on 206 patients with urinary tractography. The results were satisfactory in 79.6% (164/206), good 16.9% (35/206), unsatisfactory 3.5% (7 / 206), of which 70 cases delayed 1 h did not develop, confirmed by CT scan renal cortex thinning, after a delay of 4 ~ 24 h after 63 cases of satisfactory imaging. Conclusions: Low tension dynamic venous urography can improve the developing rate of urography, and understand the functional and organic pathological changes of the kidney. It is a reliable method to diagnose urinary disorders.
