1

best initial test in nephro

- urinalysis
- BUN
- Cr

2

urinalysis consists of

1. dipstick if positive
2. microscopic analysis

3

normally excrete which protein

Tamm Horsfall (30-50mg/24hrs)

4

transient proteinuria

BENIGN, 2-10% of population

5

benign causes of proteinuria

exercise
orthostatic proteinuria

6

single protein: creatinine = efficacy to

24hr urine collection

7

urine dipstick detects

ALBUMIN ONLY

8

normal protein excretion in 24hrs

less than 300mg

9

best initial test proteinuria

urinalysis

10

most accurate test proteinuria

protein:creatinine ratio

11

P/Cr accuracy vs. 24hr urine

GREATER ACCURACY-- faster and easier

12

finding out cause of proteinuria

biopsy

13

microalbuminuria

30-300mg/24hrs

14

microalbuminuria can lead to....

worsening renal function

15

tx of microalbuminuria in diabetic patient

ACEI/ ARB

16

diabetic patient with kidney disease, do BIOPSY when there is...

NO OPHTHALMIC DISEASE (recall what's going on in the kidneys, reflects what's going on in the eyes of a diabetic)

17

WBC's in urine

inflammation-- acute interstitial nephritis
infection

18

eosinophils with NSAID induced kidney disease

NOOOOOOOPE!!!

19

stains used to detect eosinophils in urine

Wright and Hansel stains

20

common cause for mild recurrent haematuria

IgA nephropathy

21

False positives for dipstick haematuria

Hb or Mb

22

patient presents with trauma to kidneys and dark urine... what next

microscopic exam of urine-- to detect if Hb/Mb present (Cannot tell the difference between the two, but can tell if its present or not)

23

IVP nephro answer

ALWAYS WRONG-- since slow and renal toxicity with contrast

24

dysmorphic RBC's

glomerulonephritis

25

cystoscopy indications

1. hematuria without infection or trauma
2. haematuria-- without cause on CT/US
3. hematuria with bladder mass on sonography

26

Diagnostic test for bladder cancer

cystoscopy with biopsy

27

hyaline casts

DEHYDRATION--tamm horsfall protein

28

mgmt of pre and post-renal azotemia

underlying cause; MOST ARE REVERSIBLE

29

obstruction with increasing creatinine

need BOTH kidneys to be obstructed for the creatinine to rise

30

weird cause of post-renal azotemia

retroperitoneal fibrosis
