IntroductionAccording to the Chronic Kidney Disease Prognosis Consortium (CKD-PC), 1 in 4 patients age ≥ 65 in North America has some form of chronic kidney disease (CKD), while 3 in 100 will progress to kidney failure. The aim of this study was to evaluate whether bariatric surgery alters the progression of CKD to kidney failure in patients who are severely obese.MethodsWe conducted a retrospective review of all patients who underwent bariatric surgery at our institution over the last 16 years. Kidney function and injury were assessed using the average estimated glomerular filtration rate and urinary albumin-to-creatinine ratio (uACR) over 3 months preoperatively and postoperative at 12-month follow-up. The risk of progression from CKD to kidney failure was assessed using the Chronic Kidney Disease Prognosis Consortium (CKD-PC) equation.ResultsOut of 2924 patients reviewed over this period of time, 69 (2.4%) had the recorded data necessary to assess kidney injury and the risk of disease progression to kidney failure. Patients within moderate and severe stages of CKD-related albuminuria improved the most at 12-month follow-up (by 48% and 79%; P = 0.0001 and P = 0.025, respectively). This translated to a relative risk reduction for progression to kidney failure in CKD ≥ stage 3 patients of 70% at 2 years and 60% at 5 years (both P = 0.001).ConclusionsBariatric surgery seems to improve kidney injury, especially among patients with the most severe stages of CKD. Marked 2- and 5-year risk reduction in the progression from CKD to kidney failure was observed.
