[Ultra-sound study on the growth of the fetal kidney in the second half of pregnancy (author's transl)].

Sonography was used to detect and measure the fetal kidneys. In 250 cases of pregnancies ranging from the 20th week to term growth charts for the normal growth of the fetal kidney were constructed. Considering the normal anatomical variations it is possible using these curves to detect growth retardations of the fetal kidneys. The importance of these measurements for fetal anomalies and cases of placental insufficiency with growth retardation of these organs is discussed.
