肾性糖尿病是指血糖浓度正常而尿中出现葡萄糖的一种先天性遗传性肾小管缺陷。而任何非糖尿病原因引起尿糖增高,一般划入广义的“肾性糖尿”的范畴。它们产生的基本病理是葡萄糖排出的肾阈值降低,即通过肾小球的葡萄糖到达肾小管内以后再吸收的能力降低。因为尿中出现葡萄糖不仅取决于血糖浓度,而且与肾小球的流注情况、滤过率及肾小管的再 Renal diabetes is a congenital hereditary tubular defect with normal blood glucose levels and glucose in the urine. And any cause of non-diabetic urine sugar increased, generally classified as “kidney diabetes” category. The basic pathology they produce is a decrease in the threshold of renal glucose excretion, which is reduced by the glomerular glucose reabsorption after reaching the renal tubules. Because of the presence of glucose in urine not only depends on the blood glucose concentration, but also with glomerular effusion, filtration rate and renal tubular
