Targeted versus empiric approach for prevention of recurrent kidney stones: Insights on diet therapy from a randomized trial.

In 30 seconds

This randomized controlled trial compared empiric and selective dietary therapy for preventing recurrent kidney stones in adults. The selective therapy group showed a 17% increase in daily water intake and a 38% reduction in urinary calcium oxalate supersaturation, indicating more effective dietary management compared to the empiric approach.

Key findings

• The selective therapy group increased daily water intake by 17% (p = 0.02).
• Participants in the selective group doubled their daily fruit/vegetable servings (p = 0.04).
• The selective group reduced urinary calcium oxalate supersaturation by 38%, compared to 30% in the empiric group.

Why it matters

Understanding the effectiveness of tailored dietary interventions can help clinicians provide better preventive strategies for patients with recurrent kidney stones, potentially reducing recurrence rates and improving patient outcomes.
