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

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).

Material and methods

All unique Litholink™ 24-Hour Urine outcomes for nephrolithiasis prior to medical or dietary therapy obtained at our institution between 2004 and 2020 were retrospectively reviewed. Patients with anthropometric data were classified according to body mass index (BMI) as underweight (<18.5), normal (18.5-25), overweight^25-30 and obese (>30). Litholink™ 24-Hour Urine gender specific reference ranges were used to define abnormalities.
