Pediatric Nephrology

Nephrology is the scientific study of the kidneys, particularly their functions and diseases, and a nephrologist is a physician who specializes in the kidneys. The kidneys remove waste from the body (via urine), filter toxins from the blood and help regulate the concentration of certain elements in the blood. Children whose kidneys have become seriously impaired require immediate and specialized medical care.
