MONDAY, June 18 (HealthDay News) -- Drinking lemonade helps increase urine output but does not have a positive impact on other risk factors for urinary stones, according to the results of a study published in the June issue of Urology.
Stacey G. Koff, M.D., of the Walter Reed Army Medical Center in Washington, D.C., and colleagues conducted a study of 21 patients with kidney stones who were treated in a prospective crossover trial with lemonade therapy and potassium citrate supplementation.
Although intake of potassium citrate had a positive impact on citrate levels and urinary pH, it also resulted in a significant decrease in urine volume. Intake of lemonade, on the other hand, increased urine output levels but did not have an impact on citrate levels or urinary pH.
"Dietary modifications are a promising adjunct to surgical and medical management of kidney stones. They might be better accepted by patients than medications taken three times daily," the authors conclude. "However, in the case of lemonade versus potassium citrate, the urinary parameters did not improve with lemonade."
