Kidney and hypertension
There is a unique relationship be- the ultimate determinant of BP must be renal handling
tween the kidney and blood pressure (BP): on the one hand, of sodium according to this concept. This does not imply

of function of the diseased kidney. Transplantation studies, that a renal functional abnormality, i.e. disturbed BP/
both in experimental animals and humans, documented that natriuresis relationship, is a sine-qua-non condition for
“blood pressure goes with the kidney,” a normotensive recipi- the development of any type of HT.
ent of a kidney genetically programmed for hypertension (HT) Early studies of Bianchi et al [2] and more definite
will develop HT, while conversely hypertensive patients with
renal failure receiving the kidney of a normotensive donor well controlled experimental studies of Rettig et al [3, 4]
may develop normotension.
