The Kidney

  • Leonard I. Kleinman

Abstract

The primary function of the mammalian kidney is to maintain water and electrolyte homeostasis. The kidney carries out this function by selectively excreting or retaining water and solutes as the condition dictates. In the fetus, body water and electrolyte balance are maintained largely by the placenta, so that renal maturation in utero is geared primarily to prepare the kidney for its extrauterine role. As a result, the functional capabilities of the fetal kidney are much greater than its normal functional requirements. Indeed, fetuses without functioning kidneys often manifest no water and electrolyte abnormalities. The major responsibility for water and electrolyte homeostasis is suddenly thrust upon the perinatal kidney as soon as the infant is born. Yet, as we shall see in subsequent portions of this chapter, renal maturation does not suddenly accelerate after the infant is born. Indeed, renal anatomic maturation is essentially complete in the human at the time of birth.
