Enteric hyperoxaluria is one of the most frequent complications of bariatric surgery. In this setting the prevalence of kidney stones is increased. Currently the treatment of enteric hyperoxaluria is based not only on the reduction of urinary oxalate but even controlling other lithogenic risk factors, like urinary volume and urinary citrate levels. This case report suggests a possible benefit using magnesium citrate in addition to calcium supplementation, in the treatment of hyperoxaluria caused by enteric malabsorption.
Keywords: hyperoxaluria; kidney stones; magnesium citrate.
