Abstract

Acute renal failure (ARF) is a common disorder in high-risk neonates. ARF may be oliguric or nonoliguric, the latter having a better prognosis. Risk factors for ARF include prematurity, respiratory and vascular disorders, heart failure, congenital uropathies, and the use of nephrotoxic drugs. Chemical analysis of urine and ultrasounds help differentiate the nature and the type of ARF: prerenal, intrinsic, or postrenal. Conservative management of prerenal forms of ARF consists in carefully restoring cardiac output and controlling fluid and electrolyte balances. Early relief of obstruction is mandatory in severe postrenal forms of ARF. Renal replacement therapy is often necessary when ARF is secondary to intrinsic renal damage: peritoneal dialysis is the treatment of choice. Hemodialysis and continuous venovenous hemofiltration may be used in specific cases. Overall prognosis of ARF depends on the nature and severity of the renal injury that has led to renal failure.
