Question from a stone former actively passing a stone:

I have been diagnosed with a kidney stone.  I am experiencing pain that has now moved to my side.  Occasionally I will get waves of overall abdominal pain, but the sharp pains are still generally located to the side.  How will I be able to tell when the stone has dropped to the bladder?
I’ve been drinking 4L of water (at least) a day for 8 days now and the stone still has not passed. I would rather now go into work and keep on with my life until the stone passes – I am just concerned with knowing the warning signs of when the stone is very close to passing.



During stone episodes, stones generally cause a predictable sequence
of symptoms as they move down the ureter. Initially, pain is located
in the back when the stone is located up near the kidney. As the stone
moves further down, the pain can also be located in the side and in
the abdomen. When the stone is in the lower part of the ureter, the
pain moves toward the front of the abdomen. Once a stone is entering
into the bladder, patients may also feel the urgency to urinate and
can feel pain in the groin. Once the stone makes it into the bladder,
there should be a relief of pain. While this sequence is typical, some
patients may experience different symptoms. We have more information
on this on our “What causes kidney stone pain?” page.

Staying hydrated is a good idea but it is not clear if it speeds the
passage of stones (make sure though to not drink more than about 1
liter in an hour, as water intoxication can occur with intakes of 2
liters an hour or higher). Use of certain medications, such as
tamsulosin, does appear to shorten stone passage. You should know
though that use of this medication for this purpose is “off label” and
should be discussed with your treating physician. Other factors that
influence the likelihood and speed of stone passage includes the size
of the stone and its location. Stones can take up to 6-8 weeks to
pass. If they have not passed by then, treatment may be required.


Before making any medical decisions, always consult with your treating physician.

    hi guys I see that I am one of many suffering with kidney stones. I too have been suffering for a long time I currently have a stone that 4-5mm in size. some of you may think it sounds silly but there are ways to help ease the pain. I have read many things on the net on how to help get rid of stones how to ease the pain and I have tried almost everything you can come across. I have found that lemon juice is amazing and does wonders in helping those little craters pass. mix with a olive oil helps to soften you up inside so if the stone is stuck somewhere it will start to move again. that can also be painfull if the scrapes against your insides I have personally experienced this pain but it has relieved the pain which was worse off before. now I feel the stone at the lower bottom of the bladder only it may be a little bit too big to just pass through easily so when I go out its extremely sore and then all of a sudden nothing wants to come out. until another few minutes gotta run back to the loo. I believe that apple cider vinegar also does wonders it somehow dissolves the stone although it takes a long time to do so when a stone is is put into a a glass of only apple cider vinegar therefore will take much longer being consumed. well that much I can say about getting it as far as bladder any ideas of how to get it out of the bladder as quick as possible would be highly appreciated.

    Please help! I have passed about 11 stones and out of those had 2 lithotripsy’s to have them removed. Every stone I have passed has been between 4-7 mm. I am now currently passing a stone at what the Dr says is 3mm, but I am confused as to why this one is giving me so much trouble when I have passed stones double this size and jagged. But to my question… I have been having trouble with this stone for a little over a month, at first I thought it was bad period cramps, but my period had passed and the pain got worse, so then I knew it was another stone. I waited until the pain was unbearable before I finally had to go to the er with the pain in my side and slightly in the front , they told me it was in the ureter. That was a little over a week ago. Now the pain I feel is very intense and feels like it’s right at the tip of my pee hole. I’m confused as to where the stone is actually located. I was told there is not pain once it drops to the bladder, but I have not had a moment without pain. Any insight as to where the stone might be and how much longer this will go on for? The pain is unbearable.

    I have had larger (up to 9mm) in the past. Total of 8 kidney stones all over 5mm in my left kidney. The pain is like no other. Mine all came on with no back pain to side cramping within minutes then sweating and profusely vomiting. The first time this happened my husband called the rescue because I could stop. I was admitted and have had a total of three endoscopy surgeries with stents. Last Saturday my back started hurting very slightly, in my defense I thought it was my back (I have two slipped discs where it was hurting, so pain there is normal), then side cramp suddenly and back to hysterical vomiting. Again we had to call the rescue squad, and once again another CT showed a kidney stone. This time it’s 4mm and hospital said they don’t admit until it’s over 5mm and I must pass on my own. I have now gone 1 week, no stone has past – and I have been using the mesh strainer given to me. Taking Flomax and still nothing. I fear another surgery is required, but how long should one wait? I have had slight cramping daily towards from lower abdomen.

      Go to the urologist and have a CT done. 8 stones and three surgeries later – I was told its nearly impossible to pass anything over 5mm without surgery.

    I’m still going through some issues with stones.
    Had a stone pass about 3 years ago. Very painful OMG. I did not feel the stone passing out my urethra though. Is that weird? It obviously passed.

    I had dealt with a stone lodged in my ureter. I never felt that the stone passed. I got very sick from the constant UTI’s, and even had an allergic reaction to Cipro. That sent me to the hospital overnight. Dr. placed a stint for about 3 weeks. He said he did not see an obstruction, and a CT scan proved it. But why do I still feel pain where it was, and I have another UTI? It’s been about 2 weeks of great relief until now. I’m concerned about how sick I get, and how long I’ve been suffering from this.

    I know I still have stones in my kidneys. Does this go on until all stones pass?

    • Andy says:

      I had an attack a week ago, mine felt like it lodged in the ureter too. For a few days I felt like I had a UTI and trouble peeing. After a few days, this feeling passed and pee flowed a little freer but now I have a pain kind of in my bladder and pelvic region (and in the groin when peeing and minutes after). I’m not entirely sure if it passed or not, but I’ve never had one give me such a persistent pain outside of the lower back pain that comes with these.

      From what I’ve read tho, if the doctors don’t see anything on the CT scan, don’t take that as proof of being stone free, it could be hiding in there somewhere.

      Also, when you say you get sick from the UTI, do u mean like a fever and such?
