What is Kidney failure?
'''Kidney failure''' (also called '''renal failure''') is a term used to describe when a person's [[kidney]]s stop working ([[Renal Function|functioning]]) properly, or fail. Kidney failure can be divided into two categories: [[chronic]] renal failure, and [[Acute (medicine)|acute]] renal failure. == Chronic renal failure == Chronic renal failure develops slowly, and there are not many noticeable [[symptom]]s at first. Chronic kidney disease causes [[tropinin]] levels (tropinin T only, in chronic kidney disease) to rise and elevation is less marked. Chronic renal failure can be a sign of other diseases, like [[IgA nephritis]], [[glomerulonephritis]], chronic [[pyelonephritis]], and [[urinary retention]]. Chronic renal failure will eventually develop into [[End stage renal failure|end-stage renal failure]] if it is left untreated. End-stage renal failure can only be treated with [[dialysis]] or a kidney [[Transplant (surgery)|transplant]]. == Acute renal failure == Acute renal failure<ref>{{Cite journal|last1=Lin|first1=Yongjun|last2=Ding|first2=Ying|last3=Song|first3=Shuping|last4=Li|first4=Man|last5=Wang|first5=Tao|last6=Guo|first6=Feng|date=2019-08-20|title=Expression patterns and prognostic value of miR-210, miR-494, and miR-205 in middle-aged and old patients with sepsis-induced acute kidney injury|url=https://www.bjbms.org/ojs/index.php/bjbms/article/view/4131|journal=Bosnian Journal of Basic Medical Sciences|language=en|volume=19|issue=3|pages=249–256|doi=10.17305/bjbms.2019.4131|issn=1840-4812|pmc=6716103|pmid=30997877}}</ref> develops in a short time, and symptoms are more noticeable. [[Signs and symptoms]] include: * [[Urination|Urinating]] less than usual * Changes in the amount of water in the body * [[Electrolyte]] levels that are not normal The cause of acute renal failure needs to be found quickly. Dialysis is often needed to prevent permanent damage to the body while the cause is being found. == Acute-on-chronic renal failure == It is possible to have acute renal failure on top of chronic
