对原发性肾小球疾患，部分继发性肾小球疾病及移植肾病例３７例，在Ｂ超或Ｘ线电视荧屏ＩＶＰ显像直视下，经皮肾活体组织穿刺．所取的肾组织分送光镜、免疫荧光及电镜检查，作出病理诊断，指导治疗．肾活检提供的组织学资料能直接观察到肾小球组织改变，免疫损伤及疾病的进展和演化，资料准确，指标可靠．肾活检技术和其它实验室检查相辅相成，在肾脏疾病诊断治疗中具有重要意义． Thirty-seven cases of primary glomerular disease, partial secondary glomerular disease and renal allograft were punctured with percutaneous renal biopsy under direct vision of B-mode or X-ray TV screen IVP imaging. The kidneys taken by the distribution of light microscopy, immunofluorescence and electron microscopy to make pathological diagnosis, guidance and treatment. Histological data provided by renal biopsy can be directly observed glomerular changes, immune damage and disease progression and evolution, accurate data, reliable indicators. Renal biopsy technology and other laboratory tests complement each other in the diagnosis and treatment of kidney disease is of great significance.
