Abstract
The fetal kidneys undergo a 90° rotation around their longitudinal axis during their ascent from the pelvis before they reach their final position by the end of the 8th week of fetal life (see Sect. 2.1.1) (Moore and Persaud 1998). Campbell (1970) reported only 17 cases of renal malrotation among 32,834 autopsies on adults. The true incidence of malrotation is probably understated because many patients have no clinical symptoms.
