What are my chances of successfully passing my stone?- A KidneyStoners.org Infographic

We frequently receive questions from patients trying to pass a stone who want to know whether they will be able to pass it successfully.  There are three main factors that your doctor uses to predict your chances of successful stone passage. These include stone size, stone location, and what length of time you have been trying to pass the stone. We go over each factor in the infographic below.

    Hi have a descent size kidney stone coming in at 6mm. I have the done the usual and had the CT, seen then the Urologist and been to the ER too. The stone as of Friday, was low in the left ureter and blocking the whole thing. My question is can you pass pieces of the stones without intervening or will it always pass together. I’m taking flowax and am straining my urine and found a peice of brown jagged rock like piece in my last collection.

    I suffer from a condition called MSK. It is not a very common form of kidney disease, also both of my kidneys are affected. Diagnosed at age 30, was somewhat of a relief due to chronic pain that doctors couldn’t figure out. I bounce from urologist to urologist because no one wants to be proactive in my care; each new dr says we will watch them and if I become really ill, they can be surgically removed. ( I have well over 150 stones between both kidneys) 2 days ago had to be the worst episode ever. The entire episode lasted 3 weeks. I had hydronephrosis in my right kidney and was never admitted. I spent the last 4 days of that 3 week time frame in agony while trying to urinate, ( BRIGHT RED urine) Sunday morning I had tremendous spasms and hardly any pee was coming out until I heard the unmistakable clunk of a stone into the strainer. My stone was 11mm long by 10mm wide. A few min later spasms started up again and I passed 4 more stones sizes 2mm-6mm. The rest of the day I was bleeding pretty bad and had a few clots, I guess because of the size and the amount of stones. Also, all those stones that passed were passed at home and naturally- the only medication used was Advil alternated with Tylenol. Just wanted to share because it IS possible to pass them without surgery (also depending on size of ureters and stone type)

    I just passed a 4mm stone & I’m scheduled for CT scan in morning but before I passed it I felt as if I was in labor. I felt like I constantly had to urinate & I couldn’t go, but I had the feeling to push just like you would during child birth. The stone was in the mid ureter on 5/19 last scan. It felt like something tore but no bleeding when it passed. I have some pressure in lower abdominal area still and some burning when I go to the bathroom but nothing really. Has anyone felt this or should I be concerned? I have had stones in the past but never had this feeling before. Thanks for you time and good luck to everyone.

      I just passed my stone, I don’t really know what size it is, I found it on the edge of the toilet on a wet toilet tissue, under a magnifying glass it looks like a pink coral I would say its about a 5-6 mm long & skinny, the pain was so severe in my left side of my stomach that I was upchucking every hour while spending the nights on the bathroom floor for 2 days. Suddenly I felt as if something like a blade was coming out of my urethra & no pain in my stomach, & suddenly the urine flow was smooth as honey, instantly the pain was completely gone, as if I just gave birth, when I got up I looked in the toilet & there was the stone. I was elated because the whole while I was under the impression I had eaten a contaminated food stuff. Now 3 days later I still have a dull to moderate pressure pain in my groin area especially at bed time. I have no idea if its related to passing or a new one coming. My question is could I be passing another miserable stone??? I read somewhere that eating a raw onion will pass the stone without much fuss, is that true??? I know onions contain “cysteine sulphoxides”, are those compounds a catalyst to now days pulverizing calculi?? PLEASE ELABORATE!!

    Hi, i have a stone problem but since yesterday I am having a little pain ,after having the ultrasound I found 10mm stone in the lower ureter near VUJ. Is there any any chance to pass it through urine without surgery. I consult to my doctor and he said to wait five days and giving his treatment .

  13. FF says:

    I went to the ER one month ago with severe pain and found out was because of a 2mm stone on my right kidney.
    Now I have this burning sensation and urge to pee and it hurts all day long, non-stop. I don’t know if the stone is moving but it hurts a lot. It’s being such a long time since that severe pain, isn’t it 30 days enough to pass a stone?
