In Kidney Disease or kidney failure what color of urine is produced, white, pale yellow or dark urine?

Since: One effect of kidney failure is inability of the organ to "concentrate" urine a light color is more common. If however there is loss of blood via the failing kidney (as in glomerulonephritis (infection) the urine can be "smokey" or "dark in color!

What does it mean if my right kidney hurts and my left one hurts sometimes? I also have foamy and dark urine. And I have sharp heart pain occasionally

What does it mean if my right kidney hurts and my left one hurts sometimes? I also have foamy and dark urine. And I have sharp heart pain occasionally

Its quite: UNUSUAL to feel "Kidney Pain" unless infected or otherwise abnormal (obstruction, stones, etc)
"Foamy and Dark" are very NON-SPECIFIC appearances for urine! @
The sharp "heart pain" is most likely NOT from your heart....people don't describe cardiac pain as pain "in or from" their hearts
THUS:" YOU NEED A VISIT TO YOUR PCP (Primary Care Provider) with whom you should discuss these concerns!

Bubbles on my urine? Does it mean that I have a kidney failure as I've read here, huhuh, I am also a salty eater, ?

Bubbles on my urine? Does it mean that I have a kidney failure as I've read here, huhuh, I am also a salty eater, ?

Maybe protein: Bubbly or frothy urine may be caused by protein in the urine - healthy kidneys don't leak protein into the urine. This is easily detected in a routine urinalysis test. There are many reasons kidneys may leak protein - they should be investigated. See a primary care provider for the initial evaluation. Other explanations might be soapy toilet water - try urinating into a very clean bowl to check. ...Read more

I didn't drink water for two days. Could I be severe dehydrated? Could I get kidney failure? My urine wasn't real dark just yellow.

Yes: Yes you can get kidney failure from not drinking for a longtime. But right now I think you are just dehydrated. There is no way for me to ask you why you have not had water in 2 days but if you have decided not to, it is not a good idea and I hope you are taking other liquids. If you are not, and you just don, t feel like, get evaluated. Keep hydrated. ...Read more

Sharp pain in right kidney when I pee, cloudy dark urine no matter how much I drink, constant thirst, etc. Infection or stones?

Sharp pain in right kidney when I pee, cloudy dark urine no matter how much I drink, constant thirst, etc. Infection or stones?

Hard to tell: More likely infection but cannot rule out a stone. Either will do this and it could be both, also. Urinalysis is an easy way to distinguish. Either way need to see a provider to have appropriate management. If your ct is relatively recent you can trust it in ruling out stone disease. Then infection is probable. ...Read more
