WebMar 23, 2024 · Increased kidney mass often relies on tubular growth in response to reabsorption overload during glomerular hyperfiltration. Since SGLT2i suppress hyperfiltration but concomitantly increase renal weight, it seems likely that SGLT2i have a growth promoting effect on the kidney itself, independent of GFR control. pr urakointi

Tubular Reabsorption

WebThe proximal tubule is responsible for the reabsorption of the largest fraction of filtrate. It reabsorbs about 70% of filtered NaCl and water and 100% of the filtered glucose and amino acids. Reabsorption is a highly specific process that occurs through specific proteins located on the apical membrane of kidney tubule cells.

WebThe proximal tubule is the part of the nephron that reabsorbs most of the glucose, amino acids, and other useful substances from the glomerular filtrate back into the bloodstream. If there is damage to the proximal tubule, this reabsorption process may be impaired, leading to glucose remaining in the urine (glucosuria).
