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.

 

Answer:

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.

    I have a 16mm stone that was blocking my right kidney. I had a stent placed 4 days ago and will be scheduled for ESWL soon. Very frustrated with learning that the procedure will probable have to be repeated several times to break up the stone. My doctor said that I was not a candidate for the laser treatment due to where and size of the stone and does not recommend surgical removal. I do not want to keep on repeating the shock wave procedure and suffer with continual pain trying to hopefully pass the fragments. I want this stone out now! I understand surgery is a drastic option but Wouldn’t surgery be a better option to get rid of the problem all at once? I have never had a stone before and want this thing removed.

    I have had several but the one I have now is the worst since the first 15 years ago. Lot of pain getting into the urters , but it has stalled entering the bladder , 6 weeks, lot of penal pain. 2cm, going back next week, if it hasn’t moved surgery, very scared of the stent….cysocopy, was horrible

    In June, a CT scan spotted a 5mm stone at the exit to my left kidney. I took Tamsulosin and around 4 weeks later I’d passed the stone. I hadn’t felt the stone move so was convinced it was still in my kidney and I’d need surgery. On the evening before I passed the stone, I had discomfort in my groin, an urgency to pee and a tightening and relaxing of my penis. This eased up after a while. When I had a pee it was obvious there was a partial obstruction which I’m guessing was around the prostate area. I took prescription pain killers and compatible anti-inflamatories and went to bed. In the morning I knew what was going to happen – some pressure, discomfort and out popped the stone. I couldn’t believe the lack of pain between June and when the stone appeared at the end of July. I’d had a lot of pain and blood in the previous 6 months which my doctor thought was associated with a couple of smaller stones. The 4.5mm stone I had 10 years ago was a nightmare so I know I got off very lightly this time.

      I can relate to your problem. I’ve passed a total of six stones. Two were in the area of my bladder when found, but a larger stone 1.7 centimeter completely blocked my left ureter, so the pain was extremely intense. Had lots of previous pain apparently while the stones made their way down ahead of the large stone. The position was told to me by ER doctor. Next morning before having a stent inserted, I passed the two small stones. That was on Friday morning. Pain continued over the weekend, but not nearly as bad. On Monday three more small stones passed. Had two lithotripies done to break up the large stones. Shortly after, I had the stent removed and actually passed the largest stone to date (the size of a pea). That one actually burned a lot upon passing. Probably because the stent had been removed earlier in the day. I was thankful that the doctor suggested taking pain pills left over from the second lithotripsy. Stones still remain in the kidney and I’m hoping they stay where they are, in the lower pole of my kidney. X-ray next month will tell for sure.
      I also stayed extremely hydrated, lots of lemonade and flavored waters. I really do think that helped a lot. But would really just like to hear they’re all gone!
