Background: To establish a nomogram of fetal kidney dimension for a normal pregnancy.

Methods and Materials: A prospective cross-sectional study was carried out in the imaging department of the Royan Institute. Five hundred fifty seven fetuses in 26-39 weeks gestational age were scanned for the purpose of this study. Renal measurement was performed by ultrasonography. Two dependent variables (kidney length and width) were measured and compared with one independent variable (gestational age).

Results: Analysis was performed on obtained data of 557 normal fetuses. Size chart for fetal kidney dimension are presented for each weeks of gestation in male and female fetuses, separately. The difference in renal dimension between right and left sides was not statistically significant. Linear relationships were found between the gestational age and fetal kidneys diameters, including length and width. Mean kidney width was different between male and female fetuses, but there was no statistical significant difference in kidney length of male and female fetuses. We presented mean length and width of kidney, as well as standard deviation in both right and left kidney in fetuses for each weeks of gestational age (26-39w).

Conclusion: It seems that fetal kidney size in a sample of Iranian pregnant women is longer than previously reported.
