A condition in which your kidneys suddenly stop working normally. Since your kidneys remove waste products and help balance water and salt and other minerals (electrolytes) in your blood, when your kidneys stop working, waste products, fluids, and electrolytes build up in your body. This can cause problems ...Read more

Can drinking water reverse acute renal failure?

Acute renal failure: It depends on the cause of the acute renal failure. If it is due to volume depletion/dehydration, then yes, fluids (either oral or iv), can often help reverse acute renal failure. However, often medications contribute to acute injury and may need to be stopped or adjusted. ...Read more

How effective is a ureteric stent for treating acute renal failure?

How effective is a ureteric stent for treating acute renal failure?

Depends: If the cause of renal failure is due to ureteral obstruction then very effective! The key is to address the obstruction ASAP in order to avoid any permanent damage to the kidneys. Important to monitor for post obstructive diuresis marked excessive urination after relief of obstruction. But, post-obstructive diuresis/natriuresis are good prognostic indicators of renal function recovery. ...Read more

Why is a patient with acute renal failure at a higher risk for infection?

ARF and infection: Acute renal failure (ARF) has a frequently reported mortality in 20-80% of the patients. Infection, as a cause or a complication of the syndrome, is a risk factor which adversely determines its outcome. In a study in 2009, infection occurred in four fifths of critically ill patients with ARF treated with dialysis and was in an unadjusted analysis associated with longer los and higher mortality. ...Read more

What is the difference between acute renal failure and acute tubular necrosis?

Here are some...: Acute renal failure is a general term denoting kidneys not able to good enough to manage water and electrolytes due to acute conditions such as shocks from various reasons, and acute tubular necrosis denotes what can be seen in kidney tissue under microscopic exam if biopsy is done, but not necessary for almost all cases. Clinically, they all tell us kidneys not working enough from acute causes. ...Read more

How are loop duretics used for acute renal failure and CHF though ther are contraindicaticated in borderline RF and CHF ?

Medicine vs. poison: There's a saying in healthcare: "medicines & poisons r the same chemicals given with different intent". If u r volume overloaded in acute renal failure or CHF, then u need volume reduction. The easiest & fastest way is diuretics, which "force" the kidney to get rid of water, tho side effects can occur (so u have to b monitored). If there is no volume overload in renal failure, skip the side effect ...Read more
