Akhavan et al reported an equation for estimating the renal length of a child based n age. The authors are from Mount Sinai School of Medicine and Kravis Chidren's Hospital in New York City.


Patient selection: pediatric patient 1 to 17.99 years of age



(1) age in years


estimated length in cm =

= (0.278 * (age in years)) + 6.103

= (0.3 * (age in years)) + 6



• R-squared 0.81.

• A simple age-based equation was not accurate for infants.
