The adjective renal, meaning related to the kidney, is from the Latin rēnēs, meaning kidneys; the prefix nephro-is from the Ancient Greek word for kidney, nephros (νεφρός). [37] For example, surgical removal of the kidney is a nephrectomy , while a reduction in kidney function is called renal dysfunction .
The nerves from these sources, fifteen or twenty in number, have a few ganglia developed upon them. It enters the kidneys on arterial branches to supply the vessels, renal glomerulus, and tubules with branches to the ureteric plexus. [1] Some filaments are distributed to the spermatic plexus and, on the right side, to the inferior vena cava.
The plexus is in the adventitia. These nerves travel in individual bundles and along small blood vessels to form the ureteric plexus. [2] Sensation supplied is sparse close to the kidneys and increases closer to the bladder. [2] Sensation to the ureters is provided by nerves that come from T11 – L2 segments of the spinal cord. [2]
Parasympathetic nerve supply arises through three primary areas: Certain cranial nerves in the cranium, namely the preganglionic parasympathetic nerves (CN III, CN VII, CN IX and CN X) usually arise from specific nuclei in the central nervous system (CNS) and synapse at one of four parasympathetic ganglia : ciliary , pterygopalatine , otic , or ...
In addition to the management of peripheral nerve injury, denervation is used as a medical procedure for various benefits resulting from eliminating nerve supply to a specific area of the body. Renal denervation involves using radio frequency or ultrasound to eliminate the sympathetic nerve supply to the kidney wall , aiming to lower blood ...

The afferent nerves in the kidney are also involved in maintaining balance. Mechanosensory nerves of the kidney are activated by stretching of the tissue of the renal pelvis, which can occur with an increase in the rate of urine flow from the kidney, resulting in a reflex decrease in the activity of efferent sympathetic nerves. That is ...
