What causes duplex kidney?

Duplex kidney is a result of errors in cell division that occur during the development of the fetus inside the mother’s womb. There is no evidence that suggests anything during pregnancy causes the defect. However, there is evidence to show that the condition can be passed from parent to child. If one parent has a duplex kidney, the child has a 50-50 chance of also being born with this condition.
