对９例慢性铅性肾病患者进行了肾活检，并分别作免疫荧光、光镜和电镜检查。结果发现，肾小球和肾小管均有不同程度的损害。总结了铅性肾病肾脏病理特点，计数了肾小管上皮细胞异常线粒体的数目。 Renal biopsy was performed on nine patients with chronic kidney disease and were examined by immunofluorescence, light microscopy and electron microscopy. The results showed that glomerular and renal tubules have varying degrees of damage. The renal pathological features of lead nephropathy were summarized, and the number of abnormal mitochondria in renal tubular epithelial cells was counted.
