To investigate whether afferent nerve activity occurs spontaneously in rat kidneys and identify mechanical stimuli that trigger mechanoreceptor discharges.
Electrophysiological recordings of afferent nerve activity were performed on renal nerves in anesthetized rats.
Mechanical and fluid challenges were applied, including elevating renal vein pressure and administering intravenous infusions of saline or Ringer solution.
No spontaneous afferent nerve activity was observed under baseline resting conditions in anesthetized rats.
Elevation of renal vein pressure or intravenous fluid infusion reliably elicited a slowly adapting type of afferent nerve discharge.
The afferent discharge patterns indicate that multiple fiber types respond to intrarenal pressure increases and vein distension.

Implication

Laboratory study demonstrates afferent nerve firing triggered by elevated renal pressure in rats, indicating mechanoreceptor activation by increased kidney tenseness.
