renal Flashcards
what to check for in persistent microscopic hematuria
hypercalciuria: get urine Ca/Cr ratio –> 24hr total ca excretion
cutoff for hypercalciuria
> 4 mg/kg/day urinary Ca (24 hr collection)
increased risk for renal stones
distal RTA
hypercalciuria
initial study for renal stones
XR or US
size cutoff for stones to pass/intervene
5mm
things that cause transient proteinuria
fever
exercise
dehydration
boy with SNHL, eye defects, renal failure
Alport syndrome
XL dominant
bilateral flank masses, hx of oligohydramnios
ARPKD
cystic kidney with family members who had aneurysms
ADPKD
asymptomatic abdominal mass, hematuria, hypertension
wilms tumor
good prognosis with chemo/radiation
abdominal mass with calcifications on XR
neuroblastoma
WAGR
wilms tumor
aniridia
GU anomalies
ID
UTI symptoms + mass protruding from urethral meatus
ureterocele
daytime urinary frequency, leg crossing, no nighttime symptoms
unstable bladder
tx: timed urination, anticholinergics
most common UTI organisms
E coli
Klebsiella
Enterococcus
infectious risks in nephrotic syndrome
peritonitis
invasive pneumococcal infections (bc of IG losses)
renal diseases with low complement
PSGN (C3)
MPGN (C3)
SLE (C3 and C4)
calculate FENa
(UNa/SNa)/(UCr/SCr)
what to check in patients having dialysis
HBV titers
when to start routine BP screening
age 3 at latest
tx of pheo prior to surgery
alpha blockade with phenoxybenzamine
no beta blockade alone bc unopposed alpha effect is bad
evaluation of renal HTN
renal arteriography with differential central venous renin
