AKI Flashcards
Ultrasound findings that suggest CDK
increased echogenicity, loss of corticomedullary differentiation, small kidnsy
findings other than US that suggest CDK
hypocalcemia, hyperphosphatermia, increase PTH
Define acute kidney injury
rapid deterioration of the GFR with accumulation of nirtrogenous wasts, Time: less than 3 months
How is AKI usually recongized?
rapidly rising urea and creatinine
is AKI reversible?
yeth
the EASIEST way to detect loss of kidney function
serum creatinine
1.5 increase in serum creatinine/ GFR decrease by 25 percent/ urine output <0.5 for 6 hours
RISK
2 times rincrease in serum ceatinine/ GFR decease by 50% /urine output <0.5 for 12 H
INJURY
3 times serum creatinine / GFR decrease by 75%/ <0.5 urine in 24 H or anuria for 12 H
FAILURE
complete loss of kidney function for more than 4 WEEKS, that requries renal replacement therapy
LOSS
complete loss of kidney function for more than 3 MONTHS, that requries renal replacement therapy
ESRD
hematuria 2 weeks after URTI
post streptococcal glomerulonephritis
hematuria occurs at the same time of URTI
IgA nephropathy or Glomerlonephritis
skin rash followed by antibiotic use and deterioration in kidney function
Acute Interstital Nephritis
gold standard in diagnosis of glomerulonephritis.
kidney biopsy
most common cause of primary glomerulonephritis worldwide
IgA nephropathy aka berger
livdeo reticularis is cause by ________& is seen in this ___________cause of AKI
VASCULITIS, artherothremboli
contraindications to renal biopsu
small kidney (if they biopsy it,whats gonna be left), bleeding, solitary kidney, active infection, hydronrephrosis, polycsytis kidney disase, BP > 160/90
lupus vs diabetic nephropathy, which one do u do biospy
lupus
rash + sinisitus
wegner
brown muddy casts
aka granulaar casts, specific for ATN
RBC casts
nephritis
WBC casts Dx
AIN, pyeloneprhitis
glomerular causes of AKI are
nephritic syndromes
