慢性肾病性肾萎缩的CT分度

The CT Dividing of Renal Atrophy With Chronic Kidney Disease

目的通过螺旋CT多平面重组图像,研究"肾皮质面积与腰1椎体面积的比值"对慢性肾病性肾萎缩进行分度的可行性和准确性。方法选择60例(男、女组各30例)慢性肾病后肾萎缩的病人,分别根据"肾皮质面积与腰1椎体面积的比值"、"肾脏的长短径线"对肾萎缩进行分度,比较两种分度方法的结果。结果采用"肾皮质面积与腰1椎体面积的比值"法、"肾脏长短径线"法都可以对肾萎缩进行分度,分度结果分别是:轻度肾萎缩21例、32例,中度肾萎缩31例、26例,重度肾萎缩23例、17例,分度结果存在差异。结论通过"肾皮质面积与腰1椎体面积的比值"可以对肾萎缩进行CT分度,而且比"肾脏的长短径线"法更敏感、更能反映肾脏萎缩程度,对临床的评估和治疗方案的选择更有意义。

Objective Get the ratio of the renal cortical area and lumbar 1 vertebra! body area through MPR images of spiral CT, and analyze the feasibility and accuracy of it in the dividing of renal atrophy with chronic kidney disease. Methods Choose 60 patients （male and female groups 30 cases respectively） with renal atrophy after chronic kidney disease, divide the renal atrophy according to＂the ratio of renal cortical area and the lumbar 1 vertebral body area＂ and＂the length of the kidney diameter＂respectively, and compare the results of the two methods. Results Both of the two methods can be used in dividing the renal atrophy. The results are： mild renal atrophy 21 cases and 32 cases respectively, moderate renal atrophy 31 cases and 26 cases, severe renal atro- phy 23 cases and 17 cases. The results of dividing are different. Conclusions It can be used in the CT dividing of renal atrophy through the ratio of the renal cortical area and lumbar 1 vertebral bocly area. It＇s more sensitive and better reflecting the degree of the renal atrophy than the length of kidney diameter, It makes more sense to clinical evaluation and treatment options.
