How does dehydration affect renal failure?

How does dehydration affect renal failure?

Can cause it: Severe dehydration can cause +/or worsen kidney failure. Your kidneys are sensitive to the amount of fluid circulating in your body. They are primarily responsible for excreting the extra amount into your urine. Too little fluid going into the kidneys because you are dehydrated keeps them from working well. However, if they have already failed, + you don't make urine, there won't be an effect. ...Read more

Can Renal cyst cause hight chromogranin and high vip levels? Also hypoK and dehydration.

Can Renal cyst cause hight chromogranin  and high vip levels? Also hypoK and dehydration.

No and maybe: Hi. Neither renal cysts nor tumors cause high chromogranin A nor high VIP. If the cyst is not a cyst, but a tumor, it could cause hypokalemia. Dehydration would be more likely due to the high VIP (which IS related to high chromogranin A), and the secretory diarrhea it causes. Renal cyst is probably a red herring. ...Read more

Can a person survive prerenal acute renal failure due to severe dehydration without medical help? If so, what are the consequences of not gettin help?

Can a person survive prerenal acute renal failure due to severe dehydration without medical help? If so, what are the consequences of not gettin help?

Not advised: Yes, but just because something can be done means that it should be down. A prolonged prerenal state can lead to severe tubular necrosis which is not quickly or always 100% reversible. Prolonged renal failure (prerenal or otherwise) if severe enough puts the individual at risk of death from chemical abnormalities and uremia. Short term risk death, if survives long term risk incomplete recovery. ...Read more

What does fullness of bilateral renal collecting systems mean?

What does fullness of bilateral renal collecting systems mean?

Renal anatomy: The solid tissue of the kidney is divided into an outer cortex and inner medulla. The blood is filtered and urine and is produced here. Urine is emptied into the collecting system of the renal pelvis. The ureters then transport urine to the bladder. Prominence or enlargement of the collecting system can sometimes indicate obstruction to this outflow. Bilateral means it is seen on both sides. ...Read more
