Spinach study seeks to unravel Gut-Kidney link in stone formers

NCT ID NCT05124886

First seen May 12, 2026 · Last updated May 14, 2026 · Updated 1 time

Summary

This study looks at how the gut microbiome influences urinary oxalate levels in people with enteric hyperoxaluria, a condition that raises kidney stone risk. Researchers will give participants a controlled high-oxalate diet (spinach) and measure oxalate in urine, stool, and blood. The goal is to understand the gut-kidney connection, not to test a treatment. About 80 adults—half with IBD or post-gastric bypass and a history of kidney stones, half healthy controls—will take part.
