Clinically there is no such thing as the top ten features of cryptogenic nephritis. Cryptogenic nephritis is usually divided into three categories, such as asymptomatic hematuria, asymptomatic proteinuria, asymptomatic hematuria as well as proteinuria, with different types and different features. 1. Asymptomatic hematuria: Usually there are no obvious clinical symptoms, but during urinalysis, some glomerular hematuria of glomerular origin may be found under the microscope, which is not accompanied by proteinuria. After strenuous exercise or alcohol consumption, the patient may have temporary hematuria of the naked eye, and it may be accompanied by back pain and so on. 2. Asymptomatic proteinuria: it is characterized by persistent proteinuria, the main component is albumin, which can be seen in chronic nephritis, proliferative nephritis and so on. 3. Asymptomatic hematuria and proteinuria: patients may have persistent proteinuria and hematuria at the same time. During the onset of hematuria, proteinuria may be more obvious, and with the disappearance of hematuria, proteinuria may gradually decrease. When the patient has occult nephritis, it is recommended to go to the regular hospital in time, under the guidance of the doctor to standardize the treatment.
