肾病是糖尿病的主要并发症,至少有1/3的Ⅰ型糖尿病患者在发病15～30年内发生肾衰。通常在诊断时就已经存在肾功能及结构的细微改变,包括肾小球滤过率(GFR)、肾血流量增高和肾脏增大。本文研究糖尿病患者的肾脏大小这一参数能否反映糖尿病肾病的程度。 35例Ⅰ型糖尿病患者平均年龄30±9岁(范围9～52岁),平均病程18±7年(2.5～29年),每个患者 Nephropathy is a major complication of diabetes and at least one third of patients with type 1 diabetes develop renal failure within 15 to 30 years of onset. Subtle changes in renal function and structure, including glomerular filtration rate (GFR), increased renal blood flow and increased kidneys, are usually present at the time of diagnosis. This article studies whether diabetic kidney size can reflect the extent of diabetic nephropathy. 35 patients with type 1 diabetes mean age 30 ± 9 years (range 9 to 52 years), the average duration of 18 ± 7 years (2.5-29 years), each patient
