目的 :探讨低张静脉肾盂造影的效果。方法 :选择 2 6例静脉肾盂造影患者 ,先肌注山莨菪碱 10 mg,15分钟后静脉注射造影剂 40 m l,腹部不加压 ,摄片若干张 ;选择 2 6例传统加压法静脉肾盂造影患者 ,作为对照组 ,静脉注射造影剂 40 ml,腹部加压 10 .6 7～ 12 k Pa,摄片若干张 ,比较两组显影效果。结果 :低张组显影效果好的 19例 ,差 7例 ;对照组显影效果好的 2 2例 ,差 4例。结论 :两组显影效果无显著性差异。且低张造影能避免加压法的不良影响 Objective: To investigate the effect of hypotension intravenous pyelography. Methods: Twenty-six patients with intravenous pyelography were selected. First, anisodamine was injected intramuscularly 10 mg. After 15 minutes intravenous contrast agent 40 ml was injected into the abdomen without compression. Several 26 radiographs of conventional intravenous renal pelvis Contrast patients, as a control group, intravenous contrast agent 40 ml, abdominal pressure 10 6 7 ~ 12 k Pa, a number of radiographs, compared two sets of imaging results. Results: There were 19 cases with poor imaging and 7 cases with poor imaging. There were 22 cases with good imaging and 4 cases with poor imaging in the control group. Conclusion: There is no significant difference between the two groups in developing effect. And low-contrast angiography can avoid the adverse effects of pressure
