Can a person have two kidneys at the same side?
Ectopic kidney (or “renal ectopia”) describes a kidney that isn’t located in its usual position. Ectopic kidneys are thought to occur in about 1 out of 900 births. But only about 1 out of 10 of these are ever diagnosed. They may be found while treating other conditions.
Ectopic kidneys don’t move up to the usual position. They can be located anywhere along the path they usually take to get to their normal place in the upper abdomen.
One may also cross over so that both kidneys are on the same side of the body. When a kidney crosses over, the two kidneys on the same side often grow together and become fused.
So yes a person may have two kidneys on the same side.
Hope this helps :)
