Abstract
The effect of bariatric surgery on renal functions of patients with chronic kidney disease (CKD) is not well characterized. This prospective study included 13 adult patients having chronic kidney disease who underwent bariatric surgery. The primary objective was to examine the change in glomerular filtration rate (GFR) at 6months post-bariatric surgery. Median GFR (measured by creatinine clearance) did not change significantly (55ml/min vs 59ml/min, p= 0.345) although there was a significant decrease in the protein excretion rate (1700mg/day vs 900mg/day, p= 0.001) at 6months. An improvement in the KDIGO CKD risk category was seen in 30.7% patients. In CKD patients undergoing bariatric surgery, renal function improves over the first 6months with a decrease in proteinuria and a stable GFR.
