[Ectopic supernumerary kidney. A casual finding].

چکیده
A supernumerary kidney is defined as a true accessory organ with a collector system, blood circulation and independent encapsulated tissue. In contrast with the horseshoe kidney, this congenital abnormality is extremely rare.1 Kidneydevelopment begins in 2 structures during thefifthweek of gestation: the distal portion of the wolffian duct in which the collector tubules originate, and the renal pelvis and ureters and the caudal portion of the nephrogenic blastema where the glomerules and tubules originate.1 It has been suggested that the presence of a supernumerary kidney is due to aberrant development of 2 ureteral buds at different points of the wolffian duct in contact with the nephrogenic blastema at 2 different positions. Nonetheless, other authors have suggested that this division may begin in the nephrogenic blastema.2
