The value of electron microscopy in the diagnosis of renal pathology: A survey of 360 kidney puncture patients found that: 85 cases (23.6%) in which electron microscopy played a decisive diagnostic role, 44 cases (12.2%) in which the diagnosis was revised or new elements were added, and 130 cases (35.8%) in which the two were combined. In other words, more than 1/3 of the 360 cases of pathological diagnosis of glomerular diseases were diagnosed with the help of electron microscopy. Therefore, electron microscopy is an important reference value for the pathological diagnosis of many glomerular diseases. Even some glomerular diseases can only be diagnosed by electron microscopy, such as thin basement membrane disease, Febry disease, fibrillar glomerulopathy, immunotactic glomerulopathy, and collagen III glomerulopathy.
