Nephrolithiasis risk factors for obese patients on 24‐hour urine collection metabolic evaluation

BJUI Compass, Volume 6, Issue 11, November 2025.
Abstract Objectives Twenty‐four‐hour urine collections are obtained as part of the metabolic workup for nephrolithiasis to identify modifiable abnormalities for stone prevention. We sought to discern trends in the prevalence of abnormalities based on body mass index (BMI) (kg/m2).
