(40,47,48,56,57) In these situations, the currently described technical approaches would likely be adequate to denervate
these varied articular branches, if these branches exit through the obturator foramen and course over the teardrop silhouette described above (the junction of the pubis and ischium on an anteroposterior x-ray).
A popular way for discerning the role of the renal sympathetic nerves in the regulation of renal function and haemodynamics is to denervate
one kidney (12,13).
The middle fossa approach to the anterosuperior surface of the petrous pyramid has been used by neurotologists to excise small acoustic neuromas, to denervate
the vestibular labyrinth, and to decompress and repair the proximal intratemporal facial nerve.
Since excessive activation of the renal sympathetic nerve has been an important pathological and physiological basis of hypertension onset and maintenance and renal sympathetic nerve fibers mainly access the kidneys through the renal artery adventitia, such anatomical characteristics determine that RDN could selectively denervate
most of the renal sympathetic nerve fibers.
