An improved fine needle is described for aspiration of kidney glomeruli. The needle, with a sharp inner edge 0.43 mm in diameter, is less traumatic than ordinary percutaneous kidney biopsy needles. Electron microscopy of specimens aspirated from kidneys of normal rabbits showed well-preserved glomeruli. Twenty-two of twenty-six specimens obtained from human kidneys by fine-needle aspiration contained glomeruli. Electron microscopic study of specimens aspirated from 12 patients showed that the needle provides adequate tissue for the diagnosis of diffuse glomerular diseases. The use of the fine needle widens the scope for studying the relation between glomerular fine structure and renal symptoms in many conditions in which conventional methods would not be justified.
本文描述了一种改良的细针，用于肾脏肾小球的抽吸。该针的内边缘锋利，直径为0.43毫米，比普通经皮肾活检针的创伤性小。对正常兔肾脏抽吸标本的电子显微镜检查显示，肾小球保存良好。通过细针抽吸从人肾脏获取的26个标本中，有22个含有肾小球。对12例患者抽吸标本的电子显微镜研究表明，该针可为弥漫性肾小球疾病的诊断提供足够的组织。在许多传统方法不合理的情况下，使用细针拓宽了研究肾小球精细结构与肾脏症状之间关系的范围。
