Influence of weight status on 24-hour urine composition in adults without urolithiasis: A nationwide study based on a Chinese Han population.

Nonstone-forming adults with overweight or obese statuses were at higher risks of hypertension and diabetes mellitus. Obese nonstone-formers might have a greater risk of urinary stone formation due to increased urinary phosphate excretion. Additionally, underweight status had no influence on 24-hour urine composition.
