What causes reflux in the kidneys?
Primary VUR is thought to be a genetic condition. Secondary VUR is when a blockage in the urinary tract obstructs the flow of pee and sends it back into the kidneys. Kids with this type often have reflux in both ureters. This can happen because of nerve damage, infection, or pressure on the ureter from another organ.
Does kidney reflux go away?
With primary VUR, the valve between the ureter and the bladder does not close well, so urine comes back up the ureter toward the kidney. If only one ureter and one kidney are affected, doctors call the VUR unilateral reflux. Primary VUR can get better or go away as a child gets older.
What is kidney reflux surgery?
Anti-urinary reflux surgery is done to stop urine from going back into the kidney after it reaches the bladder. This condition is called vesicoureteral reflux. Most children with reflux do not need surgery as they may eventually outgrow the reflux.

Hydronephrosis is swelling of one or both kidneys. Kidney swelling happens when urine can’t drain from a kidney and builds up in the kidney as a result. This can occur from a blockage in the tubes that drain urine from the kidneys (ureters) or from an anatomical defect that doesn’t allow urine to drain properly.
