GI/GU Flashcards
The causes of acute kidney injury (aki) can be divided into 3 categories. what are they?
pre renal
renal
post renal
explain the difference between pre renal, renal and post renal causes
pre renal: caused my decreased renal perfusion; often because of volume depletion
renal: caused my process within the kidney
post renal: caused my inadequate drainage if urine distal to the kidneys
examples of conditions that cause pre renal aki:
dehydration
heart failure
liver failure
examples of conditions that cause intrinsic renal aki:
glomerular nephritis
acute tubular necrosis (caused by rhabdo, sepsis, prolonged pre renal aki)
hypertensive emergency
examples of conditions that cause post renal aki:
ureteral obstruction ( requies bilateral obstruction)
UTI
neurogenic bladder
benign prostatic hypertrophy
Causes of peritonitis
-infection of abdominal cavity usually caused my cirrhosis or ascites
-organ perforation in abdomen
- obstruction or hole in intestines
What is appendicitis?
acute inflammation of the appendix, resulting in abdo pain, anorexia. treatment is removal of appendix
what is acute pyelonephritis?
kidney infection - bacteria causes kidney inflammation
- one of most common kidney diseases
-generally occurs as complications of ascending UTI
what is acute pyelonephritis?
kidney infection - bacteria causes kidney inflammation
- one of most common kidney diseases
-generally occurs as complications of ascending UTI
Acute pyelonephritis will commonly present as what triad of symptoms?
-fever
- flank pain
- nausea and vomiting
most common bacteria in acute pyelonephritis?
e.coli
true or false :
in acute pyelonephritis, rebound, guarding and rigidity are typically absent
True
What is one main difference in asessment/presentation between acute renal colic and acute abdomen?
acute renal colic patients will be in extreme pain, and won’t be able to find comfortable spot, whereas
acute abdomen, patients will want to lay completely still
How do NSAIDS work for renal colic? (2 ways)
- decrease production of aracadonic acid which mediate pain receptors which alleviates pain caused by distention of renal capsule
-block prostaglandins which decreases pain receptor activity and reduces ureteral contractions. they also contraxt the efferent arterioles of glomerulus causing reduction in GFR
define DKA
potentially life threatening complications of diabetes mellitus resulting from insulin deficiency
