Photo of large bladder stones

Photo of staghorn kidney stone

File photo of a large “staghorn” kidney stone removed intact by open surgery. The various parts of this stone fill up an entire kidney’s central collecting system, giving it a characteristic shape appearing similar to a deer’s antlers. Stones this size are not commonly seen intact anymore as most are now treated percutaneously and broken up before being removed.

    Oh my gosh. I am 35 and this is my srcond time with stones that I know about. I passed 2 4mmstones and 2 3mm ines. Now I have two small ones on the left and two 5mm on right. I have been given choice as I want to get pregnant in the next year to either try and psss them or do the shockwaves to break them up. I am scared about kidney damage as my 4 year old son has kidney disease and my dad is on dialysis. What should I do? Any thoughts?

    just found out I have staghorn stone. haven’t had stone(s) for 15 years, at least ones that have bothered me. when I previously had stone(s) removed it was thru liproscopy I believe. now I hear there are meds you can take to help them pass but after doing some reading it does not look hopeful for this type stone. any ideas? thanks!

    I ame 62, I presently have 2 kidney stones one measuring 5mm and the other
    4mm. I am scared of what the pain is going to be like when I pass them. I am
    on a blood thinner (Xelto) and I am scared of bleeding to much. I am drinking
    water with a lemon slice in it to see if it will desolve them a little.

      Dear Bonnie…i am 58…i have been passing kidney stones for years the biggest one i passed 3 yrs ago…..was a 9mm…..its actually not painful to me but i felt like a sharp cut that was like a second……then a few days later i felt it there and and i sat on my throne and wiggled my body and pushed and peed & it popped out.

    • Stephanie says:

      Dear Bonnie,
      Don’t be afraid. I have passed so many stones that size by myself and on Warfarin. There is a lot of blood but not like you’re going to bleed out and sometimes there isn’t blood much even on the blood thinner. Just be the stone and let it go.. Presently have something in my left kidney i hope I don’t have to have surgery for this one. WOrst pain yet and I’ve passed a 5.8 mm.. so no telling what this is. Keep your chin up! Love, Stephanie.. 48.. Bladder cancer patient

    I am a stone former too and have been for 30 years. I have had over 20 and I have passed half of them with the rest removed by lithotripsy, ureteroscopy, and PNL surgery. I have had several 24 urine chemistry tests specially called Super Saturation tests. The results show what type of kidney stones I am forming. Mine are the common ones called calcium oxalate. Much has changed the last two years regarding how to prevent them besides meds there is a special diet. I have found out I have been eating the wrong food which helps to make my kidney stones. If you google “low oxalate diet” you will find the best website regarding kidney stone prevention from the University of Chicago Medical Center. It is tells you all the veggies and grains that you can’t eat (all meats and fish are ok) besides the obvious foods such as almonds/nuts, spinach/beets, chocolate. I didn’t know that potatoes, beans, raspberries, oranges, etc where bad for me. There is a long list of food with high oxalate levels that are to be avoided. (I do eat some of them on holidays or on vacation.) This site is also interactive….you can ask questions of the MD and the dietitian!! Yes, you still have to drink water and also take in moderate amounts of calcium too. Check out this website it’s great. Good luck!

      20? I passed that many in just the past week and a half. I’ve had over 200 stones in 3 years. Tired of ER trips just for pain relief.

    • Maria says:

      God bless you. I can relate to the pain you have. Keep bugging them daily.

    • Anna Fontanez says:

      Did you get your VA team to take care of those stones yet..

    • Gare says:

      No need to wait for DOCS John, be pro-active and dissolve those stones YourSelf by drinking ample quantities(1\2 oz per lb body weight) of pure water daily, distilled is best. In addition to drinking abundant water fast until all Your pains disappear.

      • Carol says:

        That would be like 30 gallons a day of water for 135 pound person right?

        • Cat says:

          Looks like 135 times 2 oz would be 270 oz divided by 128 oz in a gallon would be just over 2 gallons a day. I didn’t know if Gare was recommending 0.5, or one to 2 ounces the way it is written.

      • Stoney says:

        That’s a lot of water, and it can’t dissolve stones. Lemonade can help stop the bonding process of some stones, but water only flushes.
