Detailed explanation-1: -These changes occur between the first and the sixth month of life, so that as early as the seventh month, the renal parenchyma shares the char-acteristics of the adult one (29). The fetal lobulation gradually disappears and it is much more frequent in the newborns with the body mass below 2000 g.
Detailed explanation-2: -Persistent fetal lobulation of the kidneys is an uncommon condition that causes the surface of the kidney to appear as several lobules instead of smooth, flat and continuous.
Detailed explanation-3: -Lobulated kidney is the result of foetal lobulation that persists into adulthood. Typically, the foetal kidneys are subdivided into lobes by grooves that disappear by the end of the foetal period.
