Renal ultrasound can show the morphological changes of the kidneys and cannot detect nephritis. The diagnosis of nephritis is mainly based on clinical symptoms and pathologic findings.
Renal color ultrasound is a common clinical imaging examination, which can find out the size and shape of the kidneys, the cortical medulla of the kidneys, the distribution of blood flow in the kidneys, and also whether the kidneys have cysts, stones or occupying lesions. However, renal ultrasound can not directly diagnose nephritis, because in early nephritis, the morphology of the kidney will not have obvious changes, and the atrophy of the kidney will appear only in the advanced stage.
To confirm the diagnosis of glomerulonephritis, you need to do urine routine, 24-hour urine protein quantification, urine microalbumin quantification, and blood tests for immune indicators and renal function, etc., through which the diagnosis of glomerulonephritis can be confirmed.
The diagnosis of glomerulonephritis can only be made through these tests. To determine the presence of glomerulonephritis, you need to consult a nephrologist for evaluation and diagnosis.
