First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study tested whether the diabetes drug pioglitazone, weight loss, or both can help prevent uric acid kidney stones in overweight people. Twenty-nine participants were randomly assigned to one of three groups for 24 weeks. The main goal was to see if these interventions could raise urine pH, which is key to stopping stone formation.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Pioglitazone (a diabetes drug) and weight loss through a lifestyle program

What this could lead to

If successful, this could point to a new way to prevent uric acid kidney stones by combining medication and weight loss.

What could go wrong

This is a small, early-phase trial with only 29 participants, so results may not apply to everyone. Pioglitazone can cause side effects like swelling and liver issues.
