Nephron adaptation to renal injury or ablation

Brenner, B. M.·1985·American Journal of Physiology-Renal Physiology

Abstract

In early stages of permanent renal injury or extensive ablation, structural and functional adaptations associated with hypertrophy partially compensate for nephron losses. Glomerulotubular balance is maintained in these conditioned nephrons by intrinsic tubule and peritubular capillary adaptations that parallel single nephron glomerular filtration rate (SNGFR). Studies of Na+-H+ exchange in renal cortical brush border membrane vesicles indicate that tubule functional adaptation is not tied to loss of renal mass per se but rather to factors such as dietary protein content that set the level of SNGFR. Likewise, the structural heterogeneity that follows chronic renal injury or extreme ablation of renal mass is less a consequence of nephron injury than of adaptation linked to dietary protein intake. Indeed, since dietary protein restriction blunts the need for compensatory glomerular hyperfiltration, there is neither a stimulus for nephron hypertrophy nor for enhanced tubule ion and fluid transport. In rats with remnant kidneys, experimentally induced diabetes mellitus, or severe hypertension, increases in glomerular pressures and flows precede proteinuria, glomerular sclerosis, and azotemia. Protein restriction prevents these hemodynamic adaptations as well as the late complications. Similar conclusions appear to be applicable to a wide spectrum of clinical circumstances characterized by reduced nephron number.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
