citation needed] Hypertensive nephropathy refers to kidney failure that can be attributed to a history of hypertension It is a chronic condition and it is a serious risk factor for the development of end-stage kidney disease (ESKD). (wikipedia.org)
citation needed] An alternative mechanism of hypertensive nephropathy is prolonged glomerular hypertension and hence glomerular hyperfiltration. (wikipedia.org)
Glomerular hypertension is a functional adaptation of the surviving nephron, which increases the filtration capacity of each individual nephron and therefore compensate for the decrease in GFR because of the loss of nephrons. (vin.com)
Using the transporter profiling approach, Dr. McDonough and her colleagues have defined how stimuli such as dietary salts, Ang II, kidney injury, and immune cytokines increase renal sodium transport in a region specific manner along the nephron and how resultant hypertension provokes intrarenal responses to decrease sodium reabsorption (via pressure natriuresis), a response that defines the blood pressure set point in the kidney. (usc.edu)
Early investigations suggested that, after sufficient damage to total functional renal mass, a series of adaptive changes lead to progressive destruction of remaining nephrons, primarily through damage to glomeruli.l This "haemodynamic theory" states that compensatory glomerular hyperperfusion and hyperfiltration, together with glomerular hypertension, result in worsening proteinuria and progressive glomerular sclerosis.

The distinction is crucial, especially in patients who have nephrotic-range proteinuria in which a kidney biopsy shows FSGS or global glomerulosclerosis (FGGS) but who do not have nephrotic syndrome (e.g., serum albumin is normal), for the lesions in patients without nephrotic syndrome are more likely to arise from secondary processes (e.g., glomerular hyperfiltration, obesity, nephron mass reduction). (renalandurologynews.com)

As a compensatory mechanism, the unaffected nephrons (specifically, the preglomerular arterioles) vasodilate to increase blood flow to the kidney perfusion and increase glomerular filtration across undamaged glomeruli. (wikipedia.org)
