Bariatric Surgery in Patients with a History of Nephrolithiasis: 24-h Urine Profiles and Radiographic Changes After Roux-en-Y Gastric Bypass Versus Sleeve Gastrectomy.

摘要: Background To evaluate the differences in 24-h urine profiles, radiographic imaging, and stone events post-Roux-en-Y gastric bypass versus sleeve gastrectomy patients with a history of nephrolithiasis. Methods A retrospective review was conducted on 102 nephrolithiasis who then underwent bariatric surgery at our tertiary academic center. Computed tomography imaging profile values were performed pre-operatively 1-year follow-up. Results total 60 Roux-en-Y 42 had gastrectomy. The group significant increases oxalate decreases citrate (p = 0.009 0.003, respectively), while stable 0.013 0.906, respectively). only predictor post-operative hyperoxaluria (OR 7.1 [95% CI 2.3-21.3], p 0.001). Radiographically, 38.3% 26.2% an increase burden, procedure rate 10.0% 7.1%, respectively. Conclusions At post-bariatric surgery, exacerbated lithogenic urinary those improved. Although not statistically significant, burden higher will likely worsen longer follow-up due to group's profiles. These findings support pre-bariatric counseling monitoring kidney stones undergo RYGB, multi-disciplinary approach between urologists general surgeons.
