较安全的造影剂的问世和大剂量使用这些造影剂,大大地提高了在肾功能不全者进行尿路造影的价值。作者研究有慢性肾功能衰竭患者,在作大剂量尿路造影和肾血管造影前后时的肾功能变化。观察15例,年龄25～70岁。基础肾脏病有:肾小球肾炎8例,高血压肾硬化2例,阻塞性泌尿道疾病2例,止痛药肾病1例,慢性肾盂肾炎1例,硬皮病1例,均有不同程度的肾功能衰竭。其中14例作大剂量静脉尿路造影,1例作选择性肾血管造影。大剂量静脉尿路造影单人剂量静脉注射碘酞酸钠150ml;动脉造影用60ml。造影检查前后均作各种肾功能检查进行对照。
The advent of safer contrast agents and the use of these contrast agents at high doses have greatly increased the value of urography in patients with renal insufficiency. The authors studied changes in renal function in patients with chronic renal failure before and after high-dose urography and renal angiography. 15 cases were observed, aged 25 to 70 years old. Basic kidney disease are: glomerulonephritis in 8 cases, 2 cases of hypertensive nephrosclerosis, obstructive urinary tract disease in 2 cases, analgesic nephropathy in 1 case, chronic pyelonephritis in 1 case, scleroderma in 1 case, both with varying degrees of Renal Failure. Among them, 14 cases were treated with high-dose intravenous urography and 1 case as selective renal angiography. High-dose intravenous urography single intravenous injection of sodium iodate sodium 150ml; Arterography with 60ml. Contrast before and after contrast examination were made for various renal function tests.
