1. A renal denervation feedback method comprising:
performing a baseline measurement of intrinsic renal nerve plexus electrical activity at a renal vessel by monitoring compound action potentials including baseline afferent and efferent signals;
denervating at least some tissue at a denervation location proximate the renal vessel after performing the baseline measurement;
performing a post-denervation measurement of intrinsic renal nerve plexus electrical activity at a measurement location on a distal side of the denervation location by monitoring post-denervation compound action potentials, after the denervating; and
determining the denervation is complete when the post-denervation compound action potentials include solely afferent signals.
