摘要
目的 评估急、慢性肾衰 (ARF、CRF)鉴别中几项检查的意义。方法 ARF、CRF各 5 0例 ,主要以肾脏病理为诊断标准 ,对病程、肾脏大小、指甲肌肝 (Ncr)、血红蛋白 (Hb)、血清钙、磷和尿比重做了分析和评估。结果以病程 <3个月或 >1年 ,Ncr≤ 84.9μmol/10 0 g N为界值 ,肾脏增大或缩小来区分 ARF、CRF。诊断符合率分别为75 %、38%、77%和 10 0 % ,两组间其他指标无显著性差异。结论 病程是划分 ARF、CRF的基础 ,但不可靠 ;肾脏增大或缩小有助于区分 ARF和 CRF,而双肾大小正常者却难于鉴别。
Objective To evaluate the important role of several adjutant examinations in distinguishing acute renal failure (ARF) from chronic renal failure (CRF).Methods The course,size of kidney,fingernail creatinine (Ncr),hemoglobin,serum calcium,phosphorous and urine specific gravity of 50 ARF and 50 CRF were analysed respectively.Results The correct rate are 75%,38%,77% and 100% respectively using criteria of course less than 3 months or longer than a year,Ncr<84.9μmol/100g N and renal enlargement or atrophia to distinguish ARF from CRF.Other adjutant examination have no obvious different between ARF and CRF.Conclusions ARF and CRF are divided according to the course,but it is not always reliable especially in CRF cases.Although the size of kidney should be useful to distinguish ARF from CRF,many cases have normal renal size.In the long course ARF or short course CRF with normal renal size and no renal function record,the Ncr measurement is of clinical value.
