Abstract

OBJECTIVE:

The aim of the study was to establish a nomogram for renal parenchymal thickness throughout pregnancy.

METHODS:

One-hundred and twenty-eight healthy women with singleton, well-dated, uncomplicated second- or third-trimester pregnancies were prospectively evaluated for renal parenchymal thickness on routine ultrasound scans. The renal parenchyma was measured in transverse and sagittal sections using predefined criteria.

RESULTS:

There were no differences in anterior or posterior parenchymal measurements in either plane by fetal sex. On sagittal-section analysis, no differences were noted between the right and left kidneys. A nomogram was established on the basis of the findings. The results showed constant linear growth of the fetal parenchyma during pregnancy.

CONCLUSIONS:

The normal fetal parenchyma grows at a constant, linear rate throughout pregnancy. The nomogram formulated may serve as a basis of future studies of the correlation of parenchymal thickness with postnatal kidney function in fetuses with urinary tract anomalies.
