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.

    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.

    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

      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.
