Key result
Selective afferent renal denervation decreased mean arterial pressure by ~15% and normalized sympathetic nerve hyperactivity in a rat model of chronic kidney disease.
Why the study?
Total removal of renal nerves impairs compensatory hemodynamic mechanisms, prompting investigation into whether selective removal of afferent renal fibers mitigates sympathetic overactivation and hypertension in chronic kidney disease.
Does selective afferent renal denervation reduce mean arterial pressure and sympathetic nerve hyperactivity in a rat model of chronic kidney disease?
Population
Rat model of CKD (5/6 nephrectomy)
Comparison
Selective afferent renal denervation via capsaicin vs CKD controls

Should not change practice; hypothesis-generating for selective afferent renal denervation in CKD hypertension.
Does selective afferent renal denervation reduce mean arterial pressure and sympathetic nerve hyperactivity in a rat model of chronic kidney disease?
Effect estimate: ~15% decrease
Selective afferent renal denervation mitigates hypertension and sympathetic overactivity while improving renal function in a rat model of chronic kidney disease.
Veiga et al. (2019) studied chronic kidney disease-induced hypertension. Selective afferent renal denervation was evaluated on mean arterial pressure (~15% decrease). Selective afferent renal denervation decreased mean arterial pressure by ~15% and normalized sympathetic nerve hyperactivity in a rat model of chronic kidney disease.
