New research shows a less invasive treatment may not be the best option for treating kidney stones.

Researchers at Duke University reviewed the medical records of nearly 50,000 patients who went to the emergency room because of painful kidney stones.

Nearly half the patients underwent shock wave therapy, which breaks up the kidney stones from the outside.

The other half underwent a minimally invasive procedure that uses a laser to break apart the stone.

Researchers found one out of ten patients who had shock wave therapy needed a repeat procedure, compared to less than one percent of the patients who chose the minimally invasive procedure.

Researchers say eliminating repeat procedures can have a big impact on medical costs, and benefit the patient.
