The diet for children with nephrotic syndrome should be determined based on the amount of protein loss in urine, generally with an intake of 1.5-2.0g/kg body weight per day, and consuming high-quality, high-protein foods such as meat, eggs, milk, and fish.
Newborns with nephroureteral separation should have kidney function checked, maintain a balanced diet, consume enough meat, eggs, and dairy for nutrition. Additionally, prenatal care and attention are crucial, and exposure to harmful substances should be avoided. Regular prenatal checks are also essential to ensure the health of both the baby and the mother.
