Implication

Does not support practice changes in hypertension or volume management; leaves open therapeutic targeting of renorenal reflexes.

Key Points

To review the anatomical and functional roles of renal sensory and efferent nerves in controlling renal hemodynamics, sodium excretion, and systemic blood pressure regulation.
Synthesized anatomical, electrophysiological, and functional studies evaluating efferent and afferent renal nerve pathways.
Evaluated physiological outcomes of renal receptor activation and electrical stimulation of afferent renal fibers on spinal and supraspinal cardiovascular centers.
Efferent renal nerve fibers regulate renal hemodynamics by altering arteriolar tone, directly stimulating renin release from juxtaglomerular cells, and increasing tubular sodium and water reabsorption.
Renal mechanoreceptor and chemoreceptor activation triggers afferent neural signals to central cardiovascular and fluid homeostasis networks, evoking both excitatory and inhibitory responses.
Neural renorenal reflexes exert a net tonic inhibitory influence on renal tubular sodium and water reabsorption as well as juxtaglomerular renin secretion.

Population

Blood pressure and sodium excretion regulation

Intervention / Comparator

Renal reflexes

This review highlights the anatomical and functional evidence that renal nerves and renorenal reflexes play a key role in regulating cardiovascular homeostasis, blood pressure, and fluid balance.

Stella et al. (1987) conducted a review in Blood pressure and sodium excretion regulation. Renal reflexes was evaluated. Neural renorenal reflexes exert a tonic inhibitory influence on tubular sodium and water reabsorption and on renin secretion from juxtaglomerular cells.
