It may be useful to remind that loop diuretics act on the thick ascending limb upstream of the macula densa, whereas the thiazide-type diuretics work donwstream the macula densa. Moreover, loop diuretic block the sodium-chloride cotransporter in the cells of the macula densa. The tubulo-glomerular feedback that permanently regulates the GFR is thus abolished, allowing the GFR to go up. This produces a permanent "hyperfiltration" that is known to induce renal damage when sustained for long periods. Thiazide diuretics, acting beyond, the macula densa should not influence the GFR
