Objective: To investigate the clinical value of new kinds of urinary erythrocyte morphology parameter in discriminating different pathology types of glomerulonephritis.
Methods: All of the 52 urine samples were from glomerulonephritis patients who had been diagnosed by renal biopsy results. The change of the percentage of acanthocytes, the size of RBC, the shape of RBC between the primary glomerulonephritis (39 cases) and secondary glomerulonephritis (13 cases) urine were detected by AVE-764 fully automatic urine cell analyzer.
Results: Acanthocytes could be found in both primary glomerulonephritis and secondary glomerulonephritis. Of the patients whose acanthocytes percentages above 10%, 94.1% had primary glomerulonephritis and 5.9% had secondary glomerulonephritis. The picture of size-shape phase were classified as strip-type, inverted triangle-type and hanging tail-type. 95.2% Strip-type cases were from primary glomerulonephritis patients. Triangle-typenormally cases were all from primary glomerulonephritis patients. Hanging tail-type cases were all from secondary glomerulonephritis.
Conclusion: High acanthocytes percentage is most common in primary glomerulonephritis, going with the size and shape of RBC can be useful in the differential diagnosis of different pathology types of glomerulonephritis.
