Urinary and Genital Disorders (Children)
Normal annual kidney growth
My 7 year-old daughter has been on prophylactic antibiotics for 4 1/2 years. Over the past two years she has had three renal ultra sounds to evaluate kidney structure and growth. I would like to know what is considered to be normal annual kidney growth for a child of her age (7 yrs, wt: 21 kg).
Measurement of kidney growth is a good way to check on the overall health of the kidneys. The kidneys do not grow very fast. They may only grow several millimeters over a year. Many radiology departments will have a kidney growth chart with the annual measurements plotted on a graph. This chart quickly and easily tells you if the kidneys have been growing appropriately over the course of time.
