Precipitate in my urine

Romix - 14-7-2015 at 14:31

Alot of precipitate in my urine, small seethrough crystals and cloudy hydroxide looking powder.

After freezing it yellow powdery precipitate shows.

Then after filtering it, I dripped 3 ml of calcium chloride, possibly with impurities, diluted HCl solute that were left in syringe, were sprayed in a bottle with crashed egg shell.

Dripped 3ml ten times, after poured whole lot in, still precipitating!

What is it? It can't be phosphate, way to much formed.

Uric acid/urate salts, perhaps? (https://en.wikipedia.org/wiki/Hyperuricosuria)

Can you measure the pH?

Can you look at it under a microscope (to see if any cells, like bacteria, are present)?

Or maybe go see a doctor...

Probably mostly calcium oxalate.
Characterizations of urinary sediments precipitated after freezing and their effects on urinary protein and chemical analyses.

They mention protein, but there should not normally be any in your urine (it is indicative of kidney problems).

I've handled many urine samples and it is common to observe a precipitate in samples that were stored frozen, even in urine from healthy people.

Are you asking because you are worried about your health? Then please go a see a doctor rather than consult random people on the internet.

I added more callcium chloride, still precipicating...
If it's oxalate, where chloride ion goes?

phlogiston - 15-7-2015 at 04:13

It just stays in solution.
Why would you expect it to go anywhere if the precipitate is oxalate?

Likely also Calcium Urate. Likely formed from Sodium or Potassium Urate in urine. Chloride ions remain balancing the Alkali metal ions.

There couldn't be so much alkali metals.

Most of this precipitate white hydroxide looking substance, with organic molecules in it. Can tell by its look.
When I poured it into different beaker, were left with crystals, less then a gramm. Colour of it something between yellow and white. they're very small. This crystals could be product of displacement reaction with other alkali metal ions, possible Sodium and Potassium. I tasted on tong filtered solution that left, and it taste like table salt.

Old School!

kecskesajt - 18-7-2015 at 08:37

And as zts16 said,see a doctor.Because you could have a bad kidney stone.

Romix - 27-7-2015 at 07:22

Tested white staff, Calcium Carbonate. Don't know about yellow crystalline powder, might be calcium phosphate

aga - 27-7-2015 at 08:38

Go and see a doctor.

Right, now that's out of the way, let's mess with your mind and body for personal amusement.

Have you been collecting samples ?

If so, filter out the precipitates, wash with ice cold water and then post a photo ...

...of the washed precipitate, not you peeing in a jar.

Like... NOW!

Don't be messing around with home chemistry here: it's your HEALTH we're talking about. :o

aga - 27-7-2015 at 09:17

I think that message has been given often enough to have been understood.

If the OP doesn't go to see a doctor, well, enough said.

Time Now to see what's in his pee before he gets prescribed something that cures the condition.

macckone - 27-7-2015 at 09:19

Or you could drink more water.
Most people don't drink enough water.
If you drink a lot of water and you still
have cloudiness then go see a dang doctor.
That is a symptom of infection.

Romix - 27-7-2015 at 12:41

Already did, and had scan done.
Prescription didn't help.
It burns under right rib when I drink very hot tea with lemon juice.
And hurts constantly

aga - 27-7-2015 at 12:47

Woohoo ! You went to see a Doctor, so every one can stop shouting about that every post.

Sorry that the kidney stone hurts like hell.

Can we carry on with the investigation of your wee now ?


macckone - 27-7-2015 at 14:43

We are now speculating on a kidney stone.
That is something chemistry can help with.
mix baking soda with citric acid in solution.
Drink up nasty tasting crap.

It helps if your stones are calcium oxalate.
Better than half of stones are calcium oxalate
or mixed composition.

For uric acid stones you need a prescription
medication (Allopurinol) and the same sodium
citrate solution which reduces urine pH.

Mine are mixed and nothing feels quite as
bad as having a 6mm spiky marble lodged in
your penis. Well maybe the cancer surgery hurt
more but ... well you get the idea.

No ! (well Yes, with a Medical Science background maybe)

I think that the OP was trying to identify the Stuff in his Wee, and was not asking anything about a Treatment of his Medical Condition.

For the Hard of Reading, the OP has been to see a Proper Doctor, had a Scan, and is undergoing Treatment.

Can we please put all this 'i really care' stuff to one side now and concentrate on looking into his wee ?


kecskesajt - 6-8-2015 at 00:04

My kin had a spiky thing stuck in his urinal system.Luckily, he was able to piss it out.The pain was so intense that he managed to call the emergency.But before that he took a small thing.And it came out.

tekkado - 30-10-2015 at 13:32

The hydroxide looking gunk could possibly be semen if you rubbed one out not long before peeing?

aga - 30-10-2015 at 14:37

Ah b'jeez. My mojo is simply not working.

Uric acid crystals in urine are orange to brown in color, and often are a symptom of an infection. They are relatively rare, especially in men. All urine is supersaturated with respect to Ca oxalate by a factor of at least 3, and most urine also is supersaturated with respect to Ca phosphates.

Ordinary physicians are useless when it comes to kidney stones, because they follow the ACP guidelines for treating kidney stones. These guidelines are deeply flawed and have been rejected by the American Urological Association. So if you have the option, see a urologist. Short of that, the citric acid treatment mentioned above is extremely effective in keeping oxalate stones from growing large enough to cause problems. If you have normal kidney function, 5 grams of citiric acid per day, reacted with a mixture of Ca carbonate and K bicarbonate and suspended in a few hundred ml of water, will do it.

Urine chemistry is extremely complex, poorly understood, and fascinating. Fred Coe at the University of Chicago maintains a wonderful website on the subject, a mixture of clinical information and thoughtful discussion of the underlying science: http://kidneystones.uchicago.edu/
