ABSTRACT

Acute renal failure is common in the neonatal period. In utero, the placenta is the organ responsible for the homeostasis and hydro-electrolytic balance; however, at the extrauterine life, kidney has three principal functions: a) regulation of the composition and volume of extracellular fluids, b) elimination toxins of nitrogen metabolism and c) secrete hormones. It has been reported an incidence of acute renal failure between 8 and 24% of the newborn babies in the NICU’s and until one third of them are prematures. Complications as proteinuria, arterial hypertension and chronic renal failure are very high particularly if the renal insult occurs during the nephrogenesis. In general, acute renal failure is characterized by an increase in serum creatinine and nitrogen products metabolism (urea and BUN), and due to the decrease of the glomerular filtrate, anuria or olyguria; however, with normal uresis could exist acute renal failure.
