应用渗透压计测定血、尿等各种体液的渗透浓度以研究水、盐代谢紊乱,国外已作为临床常规检验方法。肾脏是调节水、电解质、尿素氮的重要器官,因此,血及尿渗透压测定也是检查肾功能的重要方法之一。 本文报道应用国产FM型冰点渗透压计测定80例慢性肾脏病人的血清及尿渗透压、尿血渗比和无溶质水清除率,并结合其临床表现及其肾功能指标进行分析。
The application of osmometer for the determination of blood, urine and other body fluids infiltration concentration to study the water and salt metabolism disorders, foreign countries as a clinical routine test method. The kidney is an important organ that regulates water, electrolytes, and urea nitrogen. Therefore, the determination of blood and urine osmolality is also one of the important ways to check renal function. In this paper, we measured the serum and urinary osmotic pressure, urinary osmolarity, and non-solute water clearance in 80 patients with chronic kidney disease by using the domestic FM-type freezing point osmometer. The clinical manifestations and renal function were analyzed.
