      ]. In this study, the authors included 58 patients with a kidney stone history who were screened with non–contrast-enhanced abdominal computed tomography, serum profiling, and 24-hour urine analysis prior to deciding between sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB). The authors found that patients had increased oxalate excretion and increased calcium oxalate supersaturation after RYGB but not after SG. The authors suggested that SG should be favored over RYGB in patients with a higher risk of oxalate stone formation.
