Question 1

can you explain acute tubular necrosis?

Accepted Answer

Ischemia, drugs: Acute tubular necrosis (atn) can happen if the kidney has severely reduced blood supply (ischemia). 

This could be caused by hypotension (very low blood pressure), volume depletion (as a result of illness or trauma), problems with the blood vessels supplying the kidneys (renal artery blockage), and drugs that affect the flow of blood to the kidneys.

Drugs and toxins can also directly cause atn.

Question 2

what are the causes of acute tubular necrosis?

Accepted Answer

Ischemia, drugs: Acute tubular necrosis (atn) can happen if the kidney has severely reduced blood supply (ischemia). 

This could be caused by hypotension (very low blood pressure), volume depletion (as a result of illness or trauma), problems with the blood vessels supplying the kidneys (renal artery blockage), and drugs that affect the flow of blood to the kidneys.

Drugs and toxins can also directly cause atn.

Question 3

i have decreased urination, could this be caused by acute tubular necrosis?

Accepted Answer

Very unlikely: Decreased urination almost always relates to either reduced fluid intake or increased fluid losses such as diarrhea or increased sweating. In the rare instance when low urine output is due to kidney disease, weight gain from the accumulated water retention should be measurable on a daily bases.

Question 4

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

Accepted Answer

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.

Question 5

what usually causes acute tubular necrosis when considering acute kidney failure?

Accepted Answer

Ask your doctor: You should be seeing a specialist called a nephrologist.  They will explain it to you.

Question 6

what's the treatment for acute tubular necrosis?

Accepted Answer

Complex: Identify the cause of atn, resolve it, and prevent further blood pressure, hypoxia, or nephrotoxin insults while the kidney heals.

Question 7

how soon from acetaminophen ingestion to acute tubal necrosis?

Accepted Answer

See below: Typical time is about 4 days.

Question 8

2 year ago i developed acute pancreatitis with necrosis and fluid sacs following an ercp.  i feel ill and my immune system is low, is this related?

Accepted Answer

Possibly: The condition that led to the ERCP may be responsible for your on- going symptoms as well.  Cadmium is stored in the pancreas and would be released with inflammation. It can cause stress and inflammation and has psycho-neuro-endo-immuno toxic effects. It lowers 25-oh vit d and can increase cr-protein.

Question 9

what does this mean: 
the right adnexa shows a smooth well defined upper margin with no obvious opacification of adnexa (abrupt cuff-off)

the left adnexa shows contrast opacified tubular structure but no free peritoneal spillage seen?

Accepted Answer

: With the description provided, it is consistent with normal spill of contrast ("no abrupt cut-off")  from the right Fallopian tube, but "no free spill" from the left adnexa makes the left tube essentially non-functional for achieving pregnancy.  With the closure of the left tube, it may be appropriate for a diagnostic laparoscopy to be done to evaluate chances for pregnancy.

Question 10

biopsy report says-10 glomeruli,3 are globally sclerosed.no segmental sclerosis seen.focal acute tubular injury&atrophys seen less 5% cortex.focal global. glumerulosclerosis with mild acute tubular injury & acute interstitial nephritis,please any sol?

Accepted Answer

: You need to consult a nephrologist. You obviously are under the care of a doctor and s/he is in a better position to advise as your doctor knows more about your health than in feasible in this forum.
Wish you good health!
