Uric Acid Kidney Stones And Cranberry Juice. Since cranberry juice acidifies urine it could be useful in the treatment of brushite and struvite stones as well as urinary tract infection. Quinic and benzoic acids in cranberries are presumably precursors of the hippuric acid that is excreted by the kidneys and thereby acidify the urine.
This kind of stone is formed of ammonium phosphate and magnesium and it is formed only when there is an infection of the urinary tract is present. No significant differences were found between normal subjects and stone formers in response to cbj and therefore the groups were combined. Urinary variables were assessed in a randomized cross over trial in 20 south african men students with no previous history of kidney stones.
This kind of stone is formed of ammonium phosphate and magnesium and it is formed only when there is an infection of the urinary tract is present.
On the last 2 days of each phase 2 24 hour urine collections and blood samples were obtained for stone risk factors and serum chemistries. However cranberry juice prevents infection of the urinary tract. The best drinks for kidney stones include plain water and juices rich in citric acid such as lemon orange or melon juice. Additionally cranberry juice may also decrease urine acidity which raises the risk of formation of uric acid renal stones.
