Brennan S, et al. - A systematic review is done to ascertain the role of ultrasound imaging in assessing fetal kidney growth. Some nomograms of 2D and 3D fetal kidney size and volume have been developed. Kidney length is the most popular single fetal kidney measurement; however, it does not seem to be a good indicator of growth. In IUGR fetuses, kidney length remained similar to appropriately grown fetuses whereas AP and TS dimensions were significantly reduced. New ultrasound techniques concentrating on the parenchyma of the kidney and perfusion to the kidney ought to be investigated as they may provide more meaningful information on kidney development in the fetus and future kidney function.
