supernumerary kidney

supernumerary kidney
a rare anomaly in which there is another kidney in addition to the usual two; it develops as the result of splitting of the nephrogenic blastema, or from separate metanephric blastemas into which partially or completely reduplicated ureteral stalks enter to form separate capsulated kidneys. In some cases the separation of the reduplicated organ is incomplete (fused supernumerary k.).
