Increased ureteral back pressure enhances renal tubular sodium reabsorption.
Moderate increases of ureteral back pressure usually cause decreases of glomerular filtration rate and even greater decreases of sodium excretion. It has been assumed previously that increased ureteral back pressure does not enhance renal tubular sodium reabsorption directly and that the decreases of sodium excretion are caused by the decreases of glomerular filtration rate. In the experiments ...

Physiol. 220(5): 1205-1212. 1971.In the in situ perfused dog kidney perfusion pressure was gradually increased from 110 to 325 mm Hg. Renal blood flow remained stable until perfusion pressure exceeded 225-240 mm Hg, the glomerular filtration ra...
متن کاملNeurogenic regulation of renal tubular sodium reabsorption.
The evidence supporting a role for direct neurogenic control of renal tubular sodium reabsorption is reviewed. Electron microscopic and fluorescence histochemical studies have demonstrated adrenergic nerve terminals in direct contact with basement membranes of mammalian (rat, dog, and monkey) renal tubular epithelial cells. Low-level direct or baroreceptor reflex stimulation of renal sympatheti...

متن کاملInhibition of Renal Tubular Sodium Reabsorption by Hypernatremia.
In a recent study (1), we confirmed the observation of Bresler (2) and Toussaint and Vereerstraeten (3) that tubular sodium reabsorption (TNa) in dogs increases following plasma sodium (PNa) elevation. However, when the increase in filtered sodium (FNa) that usually accompanied an elevated PNa was eliminated by reducing glomerular filtration rate (GFR) with an aortic clamp, hypernatremia appear...
