2) There are several theories to explain the occurrence of supernumerary kidney: a) bifurcation of ureteric bud with independent penetration into metanephrogenic blastema that develop and divide in two kidneys; b) two independent ureteral buds that penetrate the metanephrogenic blastema that divides into two and c) fragmentation of metanephrogenic blastema due to linear infarcts.
