[edit] ?
When someone developes a kidney stone, how does it affect the rest of the body? [homeostasis perhaps?]
Well it depends on how big the stone is. A small stone of about 1mm-4mm affects you more in a psychological manner. These stones, though small, can be very painful especially when exiting out the urethra. The passage out of the urethra is usually painless. The pain arises from the obstruction of the ureter which causes stretching of the collecting system and capsule of the kidney and this is what produces the pain.
A bigger stone poses a much greater risk. Stones bigger than 4mm can potentially get lodged in the urinary tract. A lodged stone can collect more minerals and grow. It can block urinary flow and lead to urinary infections. It also can produce hydronephrosis and intefere with the ability of the kidney to concentrate urine and ultimately to a loss of kidney function.
An infection in the kidney can be hard to treat. If treatment is not received in time an infection can spread to nearby organs and cause sepsis. A stone can even cause a kidney to swell up and eventually rupture the system of collecting tubes.
Hope that answers your question. Greg Marlow Uriflow Specialist
For kidney stones, what other clinical diagnostic medical laboratories besides LithoLink are used by clinical specialists in urology and nephrology? Or for USA clinicians does that lab represent the gold standard? unsigned
[edit] Kidney Stone Type and Density
I have a 9mm stone at the exit point of the kidney into the ureter. I will have a procedure that electonrically 'pulverizes' the stone (hopefully). The problem is that the stone could be of a hardness that it cracks in half rather than gets pulverized into sand size particles. Is there a way to determine the hardness of a stone before deciding which procedure makes the most sense for removal? Also, will my next stone be the same hardness, or does one stone not tell the story of the next, necessarily? Sometimes you can tell how easily a stone will fracture from its X-ray appearance. Although calcium oxalate is the most common component of kidney stones this chemical takes two different forms. The dihydrate which has large delicate crystals is easily fractured whereas the monohydrate is more dense and therefore harder to fracture.
[edit] High calcium as a cause?
The article contradicts itself as far as calcium being a cause of kidney stones.
From (Secondary Prevention) "There is no convincing evidence that calcium supplements increase the risk of stone formation."
But in (Addition Information) we find "Astronauts often get kidney stones because of an increase in the amount of calcium in their blood due to a loss of bone density in zero gravity."
If an increase in calcium doesn't cause kidney stones, from where does the astronaut information come?
[edit] Don't know if this related to astronaut 's case
- I read in Readers Digest that it comes from a high protein diet.Lots of Calcium is produced to alkalinize the high acidity of protein or protein products.--Jondel 00:28, 17 January 2006 (UTC)
Calcium supplements are something completely different from raised blood calcium levels due to increased bone loss. An increased dietary calcium intake does not necessarily lead to increased blood calcium levels. The body has mechanisms controlling the absorption of calcium from the gut, thus regulating blood calcium levels. So this isn't a contradiction. --WS 17:34, 18 January 2006 (UTC)

- For added information about non-medical kidney stone removal, please consult the web site www.jumpandbump.com. This site details the use of gravity and a special technique to aid the movement of the stone down the ureter and into the bladder.
[edit] Sitcom References
Have any of you noticed that a common feature in sitcoms is to have a guy get kidney stones while a woman he knows (maybe his wife) is in the hospital giving birth? Or if it is like the Seinfeld episode it isn't in a hospital. But the thing I have noticed is they always show it as being a short process to pass the stones. I have had them, and they can take a long time to pass - sometimes weeks to be completely passed. --Kalmia 08:18, 25 August 2006 (UTC)
[edit] Tea and kidney stones
There are conflicting reports about the effect of tea on the development of kidney stones. UMM article "This study found no effects from coffee, tea, or wine, but other research has reported a lower risk with these beverages."
[edit] DISSOLVING KIDNEY STONES
My 14 year old nephew recently developed kidney stones from drinking too much soda pop. His succesful treatment consisted of stopping the soda and having him drink apple cider vinegar. Apparently the acid in the vinegar dissolved the type of stones he had. I do not know what type of stones he had or have any other information. Perhaps someone can research this.:User:68.12.236.142 14:35, 18 September 2006 Miguel
- Wikipedia is not the place to do research (WP:NOR), but report on external citable sources of information. Good point to start for medical topics is PubMed. "kidney stone vinegar" just 2 non-specific hits, "calculi vinegar" a little more promising, see PMID 1637908 - ignore the direct mention of vinegar to external skin of urostomy wounds to neutralise alkaline irritation, but next sentance states "Internal methods of treatment that are advocated in the literature include ingestion of cranberry juice and ascorbic acid to promote urine acidity". A search on "calculi acetic" yields further hits, but unfortunately few have listed abstracts. David Ruben Talk 14:12, 18 September 2006 (UTC)
- FYI, cranberry juice is also high in oxalates, so that's probably not something you want to use when treating calcium oxalate kidney stones. See: Cranberry Ups Kidney Stone Risk -- 70.20.168.170 20:08, 16 November 2006 (UTC)
- For (at least) calcium oxalate stones, patients are advised to reduce urine acidity. That's why cola soft drinks are to be avoided -- they contain phosphoric acid. And I don't think that any modern doctor thinks that you can "dissolve" kidney stones. Instead, drink lots of water to rinse them away before that become too large. — goethean ॐ 14:18, 18 September 2006 (UTC)
Calcium stones cannot be dissolved. Uric acid and cystine stones CAN be dissolved. Ingestion of vinegar, which is acetic acid, actually has no effect on acid-base balance; therefore no effect on pH of blood or urine. It would not be helpful for stones. Though an acid, the acetate (the anion or negatively charged molecule accompanying the H+ or proton) is metabolized to base or alkali: bicarbonate. So orange juice or lemonade, which have low pH can actually alkalinize the urine because not all of the citrate is citric acid. Citric acid is also an organic acid like acetic acid and will not affect urine pH. But some of the citrate in OJ and lemon juice is accompanying potassium, not protons. That citrate will be metabolized to bicarbonate and have an alkalinizing effect. Citrate helps prevent stones by binding calcium and alkalinizing the urine to increase pH and prevent uric acid stones.---David S. Goldfarb, M.D.
[edit] Celebrity Kidney Stones
Do we 'really' need a section on famous kidney stones? Most of the entries are uncited and unverifiable, and it looks like an indiscriminate collection of information to me. Miraculouschaos 17:22, 6 November 2006 (UTC)
- The section should be cleaned up but I don't oppose it in principle. The entries about Montaigne and Pepys should be kept. — goethean ॐ 19:47, 6 November 2006 (UTC)
- Such trivia section is inappropriate for this article. However I can see the amount of effort required in compiling such list and reluctantly moved contents to a new article instead of deleting them.--Countincr ( t@lk ) 14:25, 28 October 2007 (UTC)

[edit] deleted uncited questionable research
I've deleted a paragraph which was plagiarized from this website, which does not look at all like an authoritative resource on kidney stones:
http://www.youqa.cn/html/Alternative_Medicine/medicine/152597.html
If the claims are true, let's get them cited from a good source shall we?
- I've been trying to add in sources. Some of the information is proving difficult to verify, unfortunately. E.g. per the "Causes" intro, what lab urine tests are routinely run for conditions of kidney stone patients? But I'll keep looking.—RJH (talk) 17:33, 14 May 2008 (UTC)

[edit] High protein intake as a risk factor for uric acid stones
201.17.56.112 (talk) 03:41, 16 May 2008 (UTC)Carlos Daniel Llosa
The final end product of protein metabolism is urea, not uric acid. Uric acid is the final end product of purine metabolism, not protein metabolism. However, meat is probably quite high on purines, so if by "high protein diet" one means a diet high on meat, then maybe this could cause uric acid stones. Also, there are some other acids that are the result of protein metabolism, chronic acidosis could result in uric acid precipitation, caused by urine acidification. Anyways, uric acid has nothing to do with protein metabolism, this should be corrected.I don't know the source used to back this up, but there must have been a confusion somewhere.
