The Clinical Utility of Microalbuminuria in Nephrotic Syndrome with Complete Remission, Isolated Microscopic Hematuria and Renal Transplantation Donors

Using urinary microalbumin radioimmunoassay, we evaluated the clinical utility of microalbumin excretion in nephrotic syndrome with complete remission, isolated microscopic hematuria and kidney donors in reanl transplantation. The highest value in normal controls was 10.86 μg/min, and the upper normal level was set to 15 μg/min. The range of microalbuminuria in patients with nephrotic syndrome with complete remission was 1.67 μg/min to 32.5 μg/min. There was no significant correlation between the recurrence rate and microlbuminuria level in nephrotic syndrome with complete remission. The range of microalbuminuria levels in isolated microscopic hematuric patients was between 2.37μg/min and 103.2 μg/min. There was no singificant correlation between the amount of the red blood cells in urine and the level of microalbuminuria in the isolated microscopic hematuric patients. Most renal transplantation donors showed a normal range of microalbuminuria after nephrectomy. The aim of this study was to evaluate the clinical utility of urinary microalbuminuria in diseases other than diabetes. We concluded that further extensive and specific study will be required to determine the clinical utility of microalbuminuria.
