Caffeine causes a short but sudden increase in blood pressure. Research has not shown that drinking 3-4 cups of coffee a day increases the risk of kidney disease or increases rate of decline of kidney function. ... Those struggling with blood pressure control should especially drink less than three cups per day.
Caffeine and Kidney Stones
Caffeine consumption has been linked to kidney stones. Calcium oxalate stones, the most common type of kidney stone, are formed from the combined crystals of calcium and oxalate. In a study reported in the August 2004 "Journal of Urology," study participants who had a history of calcium kidney stones but normal serum calcium levels were given 6 milligrams of caffeine per kilogram of body weight after fasting for 14 hours. The caffeine increased urinary calcium levels, causing researchers to conclude there was a modest increase in the risk of developing calcium oxalate kidney stones after caffeine consumption.
I have no heard of a relationship between caffeine or tea with kidney failure but rather caffeine and kidney stones.
Not sure how excessive is too excessive but coffee-drinking is not significantly associated with kidney disease. Quite contrary to that, the WebMD notes based on a large study that coffee drinking help reduce the risk of death among kidney patients. The benefit remained "even after considering other important factors such as age, gender, race, smoking, other diseases and diet," according to one of the study's lead authors, Miguel Bigotte Vieira, of North Lisbon Hospital Center in Portugal.
Too much caffeine and theophylline cause kidney failure, and people with diabetes, high blood pressure, obesity, and genetic diseases of metabolism are more likely to have chronic kidney failure.
That drinking tea, coffee and two substances containing caffeine and theophylline lead to kidney failure because the articles inhibit the work of adenosine responsible for the return of water from the kidneys to the body before the secretion of urine is the administration of urine, and with the large number of urine increases the concentration of substances harmful to the kidney and thus in the body Such as oxalate, calcium, phosphorus and urea, which lead to renal renal insufficiency leading to renal failure.
@ Fatima Faiq
There is no any scientific evidence to prove that excessive consumption of coffee and tea causes kidney failure.
Thanks!
Yes, excesses tea and coffee is not good for our health. It also causes various health trouble.
No , but according to the case history and coffee and tea not recommended in excessive amount .

moderating how much coffe and tea you drink is the idea. too much may harm you kidney becouse of caffeine is astimulant that increase blood pressure and stress on the kidneys.
According to the results of many studies, coffee doesnt cause kidney failure, there is no relationship between them, but caffeine may causes an increasing in blood pressure.
Consumption of anything in excess will always end up with one complication or the other.
Black Tea and Kidney Stones
Drinking iced tea, including black tea, can increase your risk of developing kidney stones, small crystals that form in the ureters, according to research conducted at Loyola University. Tea contains a compound called oxalate, a chemical involved in the formation of kidney stones. Men, postmenopausal women with low estrogen and women who have had their ovaries removed are at the highest risk for developing kidney stones, the researchers noted. While some kidney stones are small enough to pass without incident, they can grow much larger and cause significant pain.
Thank you very much for all of you with all my heart for the kind and interesting information and contributions that are very useful to you. Dear Searchers and my academic colleagues

It depends on how safe and healthy his kidneys are
When people find out they have kidney disease and must make dietary changes, one of the first questions they ask is, “Do I need to give up my coffee?”
The bottom-line answer is “No.” Coffee is not bad for coffee-lovers with kidney disease
Please take a look at this paper:
Kennedy, O. J., Roderick, P., Poole, R. and Parkes, J. (2017), Coffee and kidney disease. Int J Clin Pract, 71: n/a, e12980. doi:10.1111/ijcp.12980
According I analysis coffee, it also contain the oxalic acid, but it is not harm body, human metabolism process have oxalic acid (Oxaloacetate reference biochemical information).
I analysis cocoa kernel (chocolate raw) also contain the caffeine, caffeine is not kidney disease source, I think food contain pesticide or herbicide is kidney disease source.
According to my knowledge, coffee do not effect badly on kidney because it contains oxalic acid which is useful for human body.
"Drinking coffee and tea which containing caffeine and theophylline cause kidney failure. People with diabetes, high blood pressure, obesity and genetic diseases of metabolism are more likely to have chronic kidney failure."
Overuse of coffee and tea causes kidney failure. Coffee and tea are
considered to be one of the most popular drinks for the purpose of increasing concentration and attention, without considering the harmful health caused by over-eating on all organs such as heart, liver and muscles, especially kidneys. And tea on theophylline. Dr. Mohamed Abdel Razek, Consultant Internal Medicine and Cardiacologist, said that drinking coffee and tea and containing caffeine and theophylline causes kidney failure, and is more prone to chronic kidney failure. People with diabetes, high blood pressure, obesity and genetic diseases of metabolism. He added that drinking tea, coffee and two substances containing caffeine and theophylline lead to kidney failure because the two substances inhibit the work of adenosine responsible for the return of water from the kidneys to the body before the secretion of urine is urine, and with the large number of urine increases the concentration of harmful substances Kidneys and so on in the body such as oxalate, calcium, phosphorus and urea which consequently lead to renal renal insufficiency leading to kidney failure. According to the consultant of internal and cardiac diseases, drinking one or two cups of coffee and tea, containing either 200-300 mg a day of coffee, is acceptable and there is no harm, as this amount varies in people by weight, age and health status.
My appreciation and respect for all the answers and comments, thank you "very much" to all the researchers for their valuable contributions and important information, thank you "from all my heart, greetings to all
Lead to kidney failure because the substances inhibit the work of adenosine responsible for the return of water from the kidneys to the body and with the amount of urinary increase the concentration of substances harmful to the kidney leads to kidney failure.
Coffe and tea have large amount of caffeine .
Researchs showed that caffiene increase urinary calciume levels which increase the possibility to form kidney stone ( calciume calcium oxalate kidney stones )
Drinking tea is good for your health. It may lower the risk of cancer, it can encourage weight loss, and recent studies have shown tea can help lower blood pressure. ... Black tea is rich in oxalate, a compound found naturally in many foods. Too much of it can also lead to kidney stones

It depends on environment as well as human body. I have seen many peoples having 10 to 15 cups tea daily and maintained good health. But my personal opinion we should take tea or coffee twice daily.
To drink an excessive doses formulate a great problem and even a danger which lead for kidney fail and even death.
We should try to avoid going extreme in every part of our SNACKS AND MEALS !!!
