Babies who are born prematurely often have kidney problems shortly after birth, called nephropathy (kidney disease) of prematurity. In most cases, the baby’s kidneys usually mature quickly after birth.

However, it’s common for premature babies to have problems balancing body fluids, salts, and wastes in the first four or five days of life. During this time, a premature baby’s kidneys may have trouble:

  • Concentrating urine
  • Filtering wastes from the blood
  • Producing urine

University of Miami Health System pediatric nephrologists work closely with pediatricians, neonatologists, and other specialists to give your baby the best care possible.


Urine Output Log
Because of the potential for kidney problems in the first week of life, neonatal intensive care unit (NICU) staff monitor your baby’s urine output to evaluate your child’s kidney function.

Urine Tests (Urinalysis)
Your baby’s urine may be tested for high levels of potassium, urea, and creatinine, which can be a sign of kidney function problems.


If problems arise with your baby’s kidney function, the nephrologist may restrict your baby’s fluid intake or order more fluids to balance levels of substances in the urine.
