Treatment depends on the underlying cause and severity of the kidney disorder. Options include: - Medication: To manage symptoms and underlying conditions, such as antibiotics for infections or drugs to control blood pressure. - Dietary changes: Low-sodium, low-potassium diets to manage fluid and electrolyte balance. - Dialysis: For severe kidney failure, to artificially remove waste products from the blood. - Transplantation: Kidney transplants may be necessary for children with end-stage renal disease.
