How can ureteropelvic junction (UPJ) obstruction be prevented?

Researchers have not found any link between a mother’s eating, diet or nutrition, and the formation of UPJ obstruction in an unborn child. There does not appear to be anything one can do to prevent UPJ obstruction when it is a genetic condition.

In adults not born with UPJ obstruction, reducing the chances for later development would depend on avoiding kidney stones, urinary tract infections, or trauma to the kidneys.
