Renal tubular acidosis, a kidney condition that makes the urine more acidic. Kidney stones form more easily in acidic urine. ... Uric acid, calcium oxalate, and cystine stones form more readily in acidic urine, so this prevention strategy hinges on keeping the urine slightly alkaline.
Urine, like other body fluids, can be either acidic or alkaline. Acidic substances have a pH of less than 7 and alkaline substances have a higher pH. Urine normally is slightly acid, with a pH around 6, although it can range from 4.5 to 8. Urine pH changes, depending on your diet, certain disease processes and the medications you take. Excreting acid or alkaline urine helps maintain the body's acid-base balance, the balance between acidity and alkalinity. What you eat can alter the pH of your urine, although it doesn't change the pH of your blood. Vegetarians generally have more alkaline urine than meat eaters, because meat and dairy produce acidic urine and most vegetables and fruits a more alkaline urine.
