Bariatric surgery is an effective and durable treatment option for weight loss and remission of diabetes in obesity. Incidence of acute kidney injury (AKI) after bariatric surgery has ranged between 2.8% and 8.5%, depending on the definition used in the studies. Published reports have used serum creatinine alone in determining the incidence of AKI and thereby have underestimated AKI prevalence. AKI has prognostic significance among bariatric surgery patients and is associated with increased healthcare utilization and increased mortality in patients with AKI when compared to patients who do not sustain AKI after bariatric surgery. AKI management in bariatric surgical patients is often similar to management in other postoperative patients, involving optimal volume management, avoidance of nephrotoxic agents, including contrast, and supportive care. Early involvement of nephrologists is helpful in instituting appropriate care for these patients.
