Since cranberry capsules are so good for your kidney function,possibly could they loosen up a kidney stone?!?

Well my husband has a kidney stone. 3 wks ago I took him to the ER for his pain.
He saw the doctors of course/got the pain meds.
He says it has not passed yet, and he’s not felt anything UNTIL this morning. {yesterday he took a couple of those cranberry supplements} and very early at 5am, he experienced a lot of pain and we wondered if the cranberry capsules ‘possibly’ loosened up his stone again?
pls advise ty

    If you have kidney stones you need to drink alot of water, most kidney stones can pass through the urinary system with plenty of water—2 to 3 quarts a day—to help move the stone along.

    Cranberry juice and cranberry capsules are good for UTI’s. though not very scientific here is other research.

    here is an article:
    Kidney stones are another common urinary tract problem. Most kidney stones are composed of calcium oxalate; cranberry is high in oxalic acid. The jury is still out on how cranberry may influence kidney stone development because research on cranberry’s effect on urinary oxalate levels has produced contradictory results. In one recent study, a researcher found the oxalate content of urine increases 43 percent in people taking cranberry supplements. As a result, the scientist who conducted this study warns cranberry tablets are contraindicated in people with a history of kidney stones.8

    On the other hand, another researcher found drinking cranberry juice reduces some risk factors for oxalate kidney stone formation.9 In this crossover study, people who drank cranberry juice excreted less oxalate and phosphates and more citrate than those who drank water, which would be expected to decrease their risk of forming stones. The cranberry drinkers also showed less supersaturation of calcium oxalate, which means the calcium oxalate was dissolved in the urine rather than precipitating into a solid that could form a stone.

    Other researchers have speculated that because cranberry acidifies the urine, it could help prevent stones formed from two other substances, brushite and struvite.10 (Brushite is a calcium-phosphate mineral complex. Struvite is a magnesium-ammonium-phosphate complex made from the urea produced by bacteria during a kidney infection.) Because scientists currently disagree, it will take additional research to answer the question of how cranberry influences kidney stone formation.

    Yes, it is possible. Cranberry juice is notorious for acidifying urine and making it easier to dissolve and pass kidney and bladder stones. Many doctors specifically recommend cranberry juice for this very purpose.

    NO ! also cranberry pills have been proven not to work on kidney stones. i have had them and most pass up to 3 mm but after that they have to be surgically removed. more than likely your hubby’s stone either shifted or passed. even the really small stones can cause excruciating pain, nausea and vomiting and can take several days to pass. either way you either have to take preventative meds that are for your specific type of stones or have them removed, they do not just go away. i know from experience, the first stone i had was 9mm, i had no idea i had it until i started having pain, the next was 5 mm, both had to be removed surgically. good luck, i would not wish that kind of pain on my worst enemy and i have had 3 children naturally.
