Multiple small kidney stones with the appearance of bird seed. Removed with ureteroscopy from a single kidney. Largest stone measured 4mm in size. Analysis demonstrated 85% calcium oxalate monohydrate and 15% calcium phosphate.

Photo of large bladder stones

File photo of large bladder stones removed by open incision. These have a “jackstone” appearance.

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 7mm stone and I am waiting for a surgeon, they said I can’t pass it. I’m in so much pain, my left kidney hurts, nauseated, chills and my P was rusty brown. Everything I can’t eat anything without being in pain. Waiting on the surgeon to get back to me, been sick 3 days now.

  2. Tommy says:

    I’m 61 and started having stones 4 years ago. This pain is like nothing you have experienced before. I passed several that were 2 – 5 mms. I woke up one night with the worst pain ever. I was sweating profusely and had chills and was vomiting. I went to the emergency room and they called my urologist and she had them do a cat scan on me. Test found I had a11 mm stone. They did surgery and the stone looked like a sand burr. Tests showed I had three more stones that measured 3,5 and7 mm and I’m still waiting to pass them. I feel for all of you experiencing kidney stones for this is something I wouldn’t wish on my worst enemy.

    I have a great picture of my 10mm stone that I very painfully but successfully passed.

    • D says:

      Would you please post a picture of your stone. Do you know what type of stone it is? How long did it take for you to pass the stone?

  4. Adrienne says:

    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

    • Cbortree says:

      When I was first told that I had a 5mm stone which was my 3 time having stones. It took 3 1/2 months to pass it. I was in the ER every other week with pain. I had a cystoscopy to attempt to remove the stone which was unsuccessful. They put a stent in because my ureter is displaced. But when I did finally pass it. I measured it at 10x5mm.

    • Ferdinand says:

      My kidney stones always start out as a stomach ache and the pain eventually, travels to the left or right side of my lower back. I passed two stones today that were 6mm and 8mm in size. They were spiky and sharp stones probably made up of uric acid. When you decide to pass the stones you need to prepare yourself for the pain, medication, treatment, and posture you need to pass the stone(s). The pain lasted about four weeks ranging from level 2 to level 8.
      My recommendations: 1) reduce food intake until you decide you want to try and pass the stones and take pain relievers, muscle relaxants especially for your ureters, and possible antibiotics for possible urinary infections because of damage caused by the passing of the stones.
      2) When you decide to pass the stones prep all medications you will need especially Percocet and ice packs for the back pain. Lying down on a cold stone floor with an ice pack will feel far better than medication that will no longer work in the long run if you keep using them. Passing the stone is best when you are standing up in the shower or walking back and forth in the bathroom area. Body movement will help pass the stone better than just lying in bed. You also need to drink enough water to pass the stone while at a level of pain you can tolerate. Be prepared for a high pain level when the stones pass through the penis.
      3) Preparing stone removal or preventing stones, you should reduce the food items that often promote stones such as sodas, teas, beans, and food that makes your blood system more acidic. Drinking coffee, water, apple cider vinegar (with the mother) in water and eating food that will promote a more pH basic in your blood stream may reduce stone formation. You may want to consider potassium citrate pills to lower the chance of stone formation. They are far cheaper to get outside the country.
      Hope this helps – good luck.

      My pain is always on my right side from my ribs to my hip. Just tart cherry juice dissolves kidney stones so you don’t need to get drugged up!!! I passed one this morning & only took ibuprofen. They can all act different & be extremely painful! My last two had me throwing up several times within a half hour of the pain coming on. I couldn’t even walk.

    is 12 mm stone can be cured aur we need to operate this, also laser treatment can be effective for this.

  9. Colleen says:

    I have a 13 x 8 kidney stone. Can’t see the urologist til Friday. Will this stone have to be surgically removed?

    • Ferdinand says:

      If you can’t pass the stone, if the doctor can locate the stone then using shock wave lithotripsy (SWL) is the most common treatment. The stone will be broken into parts that you may be able to pass through your body but it may still be extremely painful due to the passage may cause injury to the urinary tract as the stones pass by. Since I believe your stone is too big to pass through the ureters and urethra without breaking up before travel.

  10. Colleen says:

    I have a 13 x 8 stone. Is this considered extremly large?

  11. Brandi Quinn says:

    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

  13. 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.

    • Ferdinand says:

      Kidney stones feel like a heavy (bloated) feeling in the abdomen then it turns into a stomach ache that eventually moves left or right to the lower back area. You will also feel hot and may think you have a fever. That is the body trying to remove water from your body by sweating because the kidney is blocked and water can’t get out of your system through at least one of your kidneys. Find out what foods promoted the stone and consume less of those items in the future also drink a lot of water when you eat those items too. Simply drinking water while you are eating stone forming food will reduce your chances of forming stones.

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

  15. 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

    I have a 6.3 mm stone on my left kidney. I was diagnoses of it 2 months ago. Will it pass…i have no pain in my back. Now after one month my urine has become dark…deep yellow. What could be the reason for dark urin

    • Sally A Stanton says:

      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.
