Purpose: This study examines the effect of Roux-en-Y gastric bypass (RYGB) and laparoscopic adjustable gastric banding (LAGB) on renal function for at least 5years post-operatively in a tertiary referral center for bariatric surgery. Materials and Methods: This prospective cohort study of patients undergoing RYGB and LAGB measured renal function, blood pressure, and diabetes status pre-operatively and then 1 and 5years post-operatively. Renal function was assessed using the Modification of Diet in Renal Disease (MDRD), Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI), and Cockcroft-Gault formulae. Hypertension and diabetes were defined by the European Society of Hypertension and European Society of Cardiology joint guidelines and American Diabetes Association guidelines, respectively. A sub-group who had completed 10years post-operative follow-up was also included. Results: Estimated glomerular filtration rate (eGFR) increased over 5years after RYGB (N = 190; 94 ± 2mL/min/1.73m2 to 102 ± 22mL/min/1.73m2, p = 0.01) and LAGB (N = 271; 88 ± 1 to 93 ± 22mL/min/1.73m2, p = 0.02). In a sub-group with up to 10years post-operative date, this trend was maintained. In patients with renal impairment, eGFR improved over 5years (52 ± 2 to 68 ± 7mL/min/1.73m2, p = 0.01). Remission of hypertension was greater after RYGB than LAGB at 1year (32 vs. 16%, p = 0.008) and at 5years post-operatively (23 vs. 11%, p = 0.02). Conclusions: Bariatric surgery stabilizes eGFR post-operatively for at least 5years. In a sub-group with renal impairment, eGFR is increased in the first post-operative year and this is maintained for up to 5years. RYGB is an effective procedure in achieving blood pressure control.
