Perinatal asphyxia and renal failure in neonatal patients

Herein we discuss oliguria and azotemia in neonatal patients associated with perinatal complications, including difficult labor and delivery, and respiratory asphyxia. Renal failure in these patients is accompanied by proteinuria, microscopic hematuria and red blood cell casts, and it generally resolves in 7 to 10 days. Umbilical aortography can be helpful in determining the presence of normal kidneys in these patients.
