Clinical Case 89: Answers and Summary

Which is NOT a known renal complication of Bariatric surgery?

The renal risks of bariatric surgery are pre renal AKI, and long-term risks of nephrolithiasis and oxalate nephropathy. AKI is fairly common after bariatric surgery, with reports ranging from 2.9% to 8.5% in published studies, which have used varying definitions of AKI. Risk factors for AKI after bariatric surgery include higher BMI, lower eGFR, preoperative use of angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, and intraoperative hypotension. Bariatric surgery patients may be prone to dehydration and higher risk for prerenal AKI in the long term, although this risk has not been quantified.  FSGS is a known secondary cause of Obesity but not related to bariartic surgery.
