A Case with Renal Glycosuria

Abstract

thesizing glucose via gluconeogenesis and preventing urinary glucose loss via tubulary glucose reabsorption.1 Reabsorption of glucose which is freely filtered in the glomeruli almost completely occur in proximal tubules only. This glucose reabsorption is mostly (90%) carried out by sodium-glucose cotransporters type 2 (SGLT-2) and glucose transporters 2 (GLUT2). So in patients with normal kidney function, significant glycosuria does not generally occur until the plasma glucose concentration exceeds 180 mg/dL (10 mmol/L).2
