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.

    I have a 4mm stone that has not passed in almost 4wks now. Had a 2mm in June that gave me no issues. Can the pain from the stones also present itself as a back strain? Went to the er today and was told the stone shouldn’t be giving me this much pain but the same er told me the 4mm is very painful just 3 weeks ago when they found it. Very confused and in serious pain

    I’ve been passing stones since I was16 years old.anywhere from 2 or 3 a month up to 4 or 5 a week. I am now 42 years old. I found a urologist that does a scope and goes in and removes stones in the kidney. Well he won’t even talk to me until I get a CTscan which I have no problem with doing … But I have Medicaid and they won’t approve it , until a ultrasound and a exploratory surgery are done to show cause for the ct scan. So the doctor won’t see me to discuss the procedure without the ct and Medicaid won’t approve the ct until the ultrasound and exploratory surgery is done . REALLY COME ON. I’m still trying to figure that one out. They won’t approve a ct scan but they will approve surgery to show cause for them to approve the ct.

    Have a 5mm stone drinking plenty of water but can’t seem to pass through

      I just passed a stone that is 7mm. It took about 7 weeks to pass. I began getting concerned. Make sure you can urinate. A blockage will cause serious side effects that need immediate attention. Good luck!

  10. Christina says:

    Had a 12 mm stone which had to be surgically removed. The doctors first placed a stent to remove the blockage which was caused by the stone (Surgery #1) A week later had surgery #2 to remove the stone since we discovered the stone was a lot bigger than they were thinking.

    I was having symptoms in the beginning (vomiting, fever) which was over a month ago but did not relate them to a kidney stone. Thought it was stomach bug. The back pain I thought was pulled muscle which I took Tylenol. This was first kidney stone.

    One time I urinate and to Gray balls came out in my urine are those kidney stones

  12. Jeff says:

    I passed a 6mm X 2mm stone that had moved down to the top of my bladder. Took .4mg Tamsulosin/Flowmax daily, and AOR Classic Series herb Chanca Piedra (stone breaker) 500mg 2 pills 4-6 times/day. Also lemon juice and Braggs Vinegar (with mother) 2 tbls in water 3 times per day … took 6 days. Felt like the stone broke up a bit and seemed to be coated and not too sharp (chanca piedra maybe coated it?). I think the vinegar helped too … google this info and decide … good luck

      You need to see a Urologist.Today i had a 10mm.stone . They used a Laser to blast it,am home now,will see what happens next. So glad thy found it,was having vomiting & diarhia(sp),getting de-hydrated etc.Had to go to get re-hydrated.Hope I feel better soon. good luck.

    • C Thomas says:

      6.3mm is typically not passable. Stones less than 5mm usually are. Blood in your urine /could/ be the reason, but may have to do with certain dietary factors. It doesn’t have to be crimson red to contain blood. Regardless, make an appointment with your urologist at your earliest convenience. Nip it in the bud because you don’t want to have to deal with a 6.3mm stone that gets jammed at the end of your ureter. It’s super painful and if lithotripsy won’t work (some stones are more difficult to break), ureteroscopy is often the procedure recommended.
