| renal glycosuria | The recurring or persistent excretion of glucose in the urine, in association with blood glucose levels that are in the normal range; results from the failure of proximal renal tubules to reabsorb glucose at a normal rate from the glomerular filtrate (low renal threshold); defect in the glucose carrier in the nephron. Synonym: diabetes innocens, normoglycaemic glycosuria, renal diabetes. (05 Mar 2000) |
