What is the probable cause of his current kidney problem?

It's not too much sugar. It could be some sort of bacteremia (bacteria in the blood). There needs to be more tests performed to answer this question with certainty, but it could be a blood infection leading to abnormal erythrocytes. The swollen hands and face make me think that it's an inflammatory response to the infection.

Mostly an upset stomach or diarrhea.  Long-term overuse has been linked to kidney problems, but nothing definitive.

Call your nephrologist (kidney doctor)

Especially if you are male, you need to see a doctor right away. My uncle, who felt just fine, suddenly had blood &, as he described it - "ickies & other matter", in his urine which quickly resulted in him not being able to go at all. Turned out he had advanced renal (kidney) cancer & was totally unaware of it. Please don't put off seeing the doctor, even if you find out it isn't something quite as horrible because I'd hate to think of anyone having to go through the mess he's just been through. And, before you think, "No, that couldn't be it;" stop to think of the fact that you aren't supposed to get blood & stones in your urine. Call for an appointment today, even if you have to visit a free clinic.\n\nGood luck!

I'm actually more surprised that you're taking the time to ask an informal internet forum rather than checking him into the hospital. Unfortunately, your question contradicts itself in that you say he's basically in good health, yet he has advanced prostate cancer, has had 2 strokes and 2 TIAs, with only 30% kidney function. (I would tend to think that dialysis might be in order.) I wouldn't exactly call that good health, basic or otherwise. If his prostate cancer is advanced, and he doesn't receive treatment, eg., have his prostate gland removed (this may not save his life if the cancer has spread), then he most certainly will die. In which case, he should be made to feel as comfortable as possible. He can be treated with various meds, such as morphine, for the pain if recovery is deemed unattainable, but without treatment he most definitely with feel pain and tremendous discomfort. Unless he's been diagnosed as terminal, get him into surgery ASAP. Besides, at 87, or any age for that matter, why would you want to experience any pain at all, if you could help it???

If you can tell it's a muscle issue, get a massage & go to a chiropractor. If you're unsure, go to a doctor & make sure it's not your kidneys.

Most likely is a urinary tract infection (bladder infection) followed by a possibly but unlikely kidney stone followed by other more serious but much less likely possibilities.  He should be taken to his pediatrician for a urinanalysis to verify.  He will need an antibiotic to shake the infection.  I would not ignore it, even if it stopped.  It is possible his first void tomorrow morning will be bloody too.  If he starts to exhibit fever or vomiting go to the ER tonight rather than wait for an office visit tomorrow.

A patient with that amount of kidney function loss would no doubt already be under the care of a nephrologist (kidney specialist) I think this question seems a little odd since I would have to wonder without medical specialty care how on earth  she A) knows she has only 1/3 of 1 kidney functioning and B) how does she know she has tumors. It is common for diabetics to be on dialysis and this person would undoubtedly be on dialysis again prescribed by a physician at some level. Are you sure you really have all the facts here?

I did hear that he has been sick...he said that on the Oprah show. Something like kidney problems. Sorry I don't know more but yes, I did notice.

pregnancy could be the cause or faulty nutrition \n \na good website with some other possibiltites is http://www.wrongdiagnosis.com/sym/abdominal_mass.htm\n\nlet me no if this helps, i hope it does\n\nWhen a kidney is enlarged, one has to determine whether the kidney tissue itself (what makes the urine) is larger than normal, or whether the collecting system, that which collects the urine and transports it to the bladder, is larger than normal. Usually, enlargement refers to the collecting system and in a very crude sense means that the "plumbing" is distended or larger than normal. \n\nThis can be due to many causes. The greatest concern is whether the dilation is due to a partial obstruction in the drainage system. Another cause can be backflow of the urine from the bladder to the kidney, called reflux. Other causes can be abnormal bladder function such as infrequent voiding patterns or excessive voiding related to an overactive bladder. Often, however, the dilation can be normal, indicating that there is no abnormality and the child simply has large "pipes" so to speak. X-ray tests can help differentiate between these different possibilities.

It could be a number of things. It could be a virus. Or has he perhaps been taking any medications in which this might be a side effect? \nWhatever it is, since it has been going on for over two weeks, he definitely needs to consult a physician.

your friend would know if it was a kidney infection because his back would be really sore and he would have to pee all the time

you probably should check to see if your pregnant or this could be a kidney infection.

Is there anybody else in the family that could be a match? That's always a good place to look first. You have my prayers too hun. Try to find friends who may be a match too. Keep searching dear, you're right, God has a plan for you, and believe it's a new kidney. Good luck on your search

My husband was told by his nephrologist that because of the high protein in his urine that a renal biopsy was the only way they could tell if he has IGA Nephropathy.This has not been done yet, because of lack of proper health insurance. His doctor is keeping him on high doses of blood pressure medicine and another med. Monitoring if the protein stabilizes or goes higher.

I think the problem is that he has been SKIPPING his meds.  As far as a urine test goes, it seems to me that he doesn't give a **** for America, so a pee is also unlikely.

you may be loosing large amount of salt from the body by any form.You may need to have a blood test- serum electrolytes ,Renal fuction test. May be nothing serious.Second probelm is not a bad problem.
