Controlled Metabolic Diet Reduces Calcium Oxalate Supersaturation but Not Oxalate Excretion After Bariatric Surgery
Urology, 05/09/2012
Pang R et al. – A controlled metabolic diet normal in calcium, moderate in protein, and reduced in oxalate can positively affect urinary calcium oxalate supersaturation after bariatric surgery. However, this diet did not appear to decrease urinary oxalate excretion. Therefore, restriction of dietary oxalate alone might not be enough to reduce urinary oxalate excretion to normal levels in this group of patients with known enteric hyperoxaluria. Additional strategies could be necessary, such as the use of oral calcium supplements as oxalate binders and a lower fat diet.
