The Claim
In patients with calcium oxalate kidney stones and enteric hyperoxaluria, each 0.5-unit decrease in urine pH is significantly associated with a 7.4 mL/min/1.73 m² reduction in estimated glomerular filtration rate, independent of stone burden and other metabolic factors.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In people with calcium oxalate kidney stones and enteric hyperoxaluria, lower urine pH is linked to reduced kidney filtering capacity, with each 0.5-unit drop in pH corresponding to a 7.4 mL/min/1.73 m² decrease in estimated glomerular filtration rate.
See the scientific wording
In patients with calcium oxalate kidney stones and enteric hyperoxaluria, a lower urine pH is significantly associated with reduced kidney function, with each 0.5-unit decrease in urine pH correlating with a 7.4 mL/min/1.73 m² reduction in estimated glomerular filtration rate, independent of stone burden and other metabolic factors.
When the intestine cannot absorb fat properly, it loses bile acids, which causes calcium to bind to fat instead of oxalate. This leaves more oxalate free to be absorbed into the blood, increasing oxalate in the urine. At the same time, the intestine loses bicarbonate, making the blood more acidic. The kidneys respond by excreting more acid, which lowers urine pH. This chronic acid load damages kidney tubules, triggers scarring, and reduces the kidneys' ability to filter blood.
What the research says
1 studyIn people with kidney stones caused by intestinal problems, the more acidic their urine is, the worse their kidneys work — even when you account for how many stones they have or other health factors. The study found this link clearly and directly.
