The amount of urine leaves from the body signifies the body health of a pediatric patient. Abnormal urination is the clear indication of various kidney related problems. Urine that passes from the body is a mixture of water and other chemicals like potassium, sodium, creatinine, and urea. A normal urine output of the infant is 2 ml/kg/hour and for a toddler it's 1.5 ml/kg/hour. Use this UOP calculator to do pediatric urine output calculation and measure your child's urine output.
