UW Flashcards
MCC of painless hematuria (evaluation)
bladder cancer
if older than 35 –> CT and cytoscopy
gross hematuria - prostate?
BPH
not cancer
hematuria - best initial test
urinalysis to rule out and confirm microhematuria (more than 3 RBCs)
reccomendations for patient with renal calculi
- increased fluids
- low sodium
- normal calcium
medication that cause urinary retention (and manegment)
anticholinergics
stop them + cathetirization
ethylen glycol (antifreeze) - stones?
calcium oxalate
osmolar gap?
measured serum osm - calculated serum osm
causes of combination of osmolar gap and and high anion gap met acidosis
acute ethanol (MC)
methanol
ethylen glycol
methanol toxicity
blindness
management of acute oliguria
bedside bladder scan to assess for urinary retention
- retention (MORE THAN 300 ml) –> catheter to decompress –> serum + urine bioch +/- image –> treat underling
- no retention –> serum + urine bioch +/- image:
a. pre-renal (IV fluids or treat underling)
b. renal cause -> treat underling
oliguria means
less than 250 ml in 12 hours
hepaternal vs pre-renal
hepatorenal does not respond to fluids
hepatorenal syndrome treatment
- address precipitating factor
- splachninc vasoconstrictor
- liver transplantation
MCC of death in dyalisis patients
Cardiovascular
MCC of death in patients with renal transplantation
cardiovascular
MC extrarenal manifestation of ADPKD
hepatic cysts
GI complication of ADPKD
colonic diverticula
urate crystals - shape
needle
GI symptoms of ureteral colic
vagal reaction –> ileus
aspirin intoxitation - ph
normal
medication to fascilate stone passage
a1 blocker (tamsulosin) –> act on distal ureter
management of ureteral stones
symptomatic relief –> urosepsis, acute renal failure or complete obstructiion?
yes –> urology consult
no –> stone siize:
less than 10 mm –> hydration pain control, a blocker
bigger than 10 –> urology consult
uncontrolled pain or no stone passage in 4-6 weeks –> urology consult
bladder cancer screening
not recommended (even if RFs)
MC nephrotic syndrome associated with thromboembolism
membranous nephropathy
glomerular vs non glomerulal hematuria regarding type
glomerular usually microscopic
nonglomerular usually gross
glomerular vs non glomerular hematuria regarding urinalysis
glom: blood + protein, RBCs casts, dysmoprhic RBCs
non -glom: blood but no protein, normal appearing RBCs
SE of acyclovir on kidneys (treatment)
crystaluria –> renal tubular obstruction
administer fluids with the drug
etiology of crystal induced acute kidney injury
acyclovir sulfonamides MTX ethylene glycol protease inh Uric acid
clinical presentation of crystal induced acute kidney injury
usually asymptomatic
AKI in less than 7 days from the starting drug
hematuria, pyuria, crystals
treatment of crystal induced induced acute kidney injury
stop medication
fluids
loop duretics
evaluation of met alkalosis
urine chloride
low –> vomiting / NG aspiration, prior diuretics
high –> hypervolemia (aldosterone), hypovolemia/evolemia (current diuretics, Barrter, gitelman)
medications that causes SIADH
SSRI, carbamazepine, Cyclophosphamide, NSAID
hypokalemia in alcohoics is refractory - why
hypogmagnesemia (removal of inhibition of renal excretion)
stones - best initial test
U/S (NOT URINALYSIS)
causes of edema in nephritis
FLUID RETENTION
urinary retention due to anticholinergics
detrusor hypocotractility
Most sensitive screen for nephropathy
RANDOM urine for microalbumin/creatinine ratio
24h is more accurate but it is inconvenience
how to correct low Na+
3% salide solution
not exceed 0.5 mEg/L/hr to
best options for renal transplantation
in order
- living related donor
- living unrelated
- cadaveric
advantages of renal transplantation over dyalysis
- better survival + quality
- autonomic neuropathy stabilzes or improves in diabetics
- return to normal endocrine, sexual and reproductive functions
- anemia, bone disease and hypertension better control
drug induced intestitial nephritis - treatment
stop the related drug (not steroids)
evaluation of hyponatremia
serum osm more than 290?
yes –> marked hypogl / advanced renal failure
no –> urine osm less than 100?:
- yes (polydipsia, malnutriotion)
- no –> check urine sodium
if if less than 25 –> SIADH, adrenal ins, hypoth
if it is more than 25 –> vloume depltion, cirrhosis, CHF
psychiatric disorder associated with 1ry polydipsia
schizophrenia
