Dietary oxalate absorption and microbiome diversity in patients with nephrolithiasis and hyperoxaluria: a stable isotope technique.

With this study, we aim to gain insight in the influence of dietary oxalate on urinary oxalate levels by quantification of the intestinal oxalate absorption in patients with recurrent idiopathic calcium oxalate stones, primary hyperoxaluria, and…
