Evaluation of nuclide renal dynamic image in diagnosing diabetic nephropathy.

Twenty non-insulin dependent diabetics were given nuclide renal dynamic image examination to investigate its significance in the diagnosis of diabetic nephropathy (DNP). The results showed that 1) the glomerular filtration was hyperfunctioned in the diabetics with less than 5 years course, whereas it was impaired in the diabetics with over 5 years course and 2) nuclide renal dynamic image could reveal the glomerular hyperfiltration without beta 2-microglobulinuria or microalbuminuria, suggesting that it is superior to the clinical biochemical parameters in the diagnosis, especially in the early identification of DNP.
