Objective To evaluate the changes of glomerular filtration rate (GFR), effective renalplasmaflow (ERPF) and microalbuminuria in early diabetic nephropathy (DN) and their correlation.
The renalplasmaflow of chronic nephritis patients with hypertension and common type was more lower than that of patients with normal kidney function(P<0.01);
