Q

ANP and BNP

A

the heart has too much volume so it releases these hormones to increase filtration and secretion of H20 and Na

17
Q

Upper Urinary Tract obstruction happens where? symptoms? treatment?

A

-In the kidney and ureters due to kidney stones
-RENAL COLIC, dull aching flank pain, nausea, HEMATURIA
-treatment is drink water, lithotripsy

18
Q

How big does the kidney stone have to be to have it surgically removed?

A

more than 5mm

19
Q

Happens due to prostate enlargement
causes nocturia which is peeing in the night

A

lower urinary tract obstruction

20
Q

Renal Cell carcinoma

A

most common tumor which causes hemturia, flank pain, weight loss, and a palpable flank mass

21
Q

transitional cell carcinoma

A

bladder tumor
causes painless hematuria
treatment consist of LOCAL chemotherapy

22
Q

Local vs systemic chemo

A

local is when its directly attached to the bladder while systemic is intravenous

23
Q

What is caused by e.coli? It’s seen in older women who are sexually active or people who have catheter, DM, or immunosuppressants.

A

UTI

24
Q

How does the host defend itself from a UTI?

A

We have protective membrane, washout phenomenon (washes out by peeing), and local immune response

25
Q

This is when only the bladder is infected

A

acute cystitis

26
Q

Urethritis

A

inflammation of urethra

27
Q

Manifestations of UTI? subjective and objective?

A

Subjective: dysuria (pain while peeing), low back pain, urgency
objective : nocturia, hematuria, Pyuria (puss)

28
Q

Pyelonephritis

A

e.coli infection in upper urinary tract
causes flank pain, nausea
discovered by doing urinalysis, and IVP
treatment: antibiotics

29
Q

This is an x ray with contrast

A

IVP;intravenous pyelogram

30
Q

What cell covers the glomerular capillaries?

A

podocytes

31
Q

Acute glomerularnephritis

A

glomerular inflammation due to infection
there are two types due to immune problems or nonimune

32
Q

-Type III hypersensitivity to antibodies
-Happens because of streptococci seen in strep or impetigo
-causes hypertension, hematuria, periorbital edema, proteinuria
treatment- corticosteroids, antibiotics, dietary restrictions

A

Immune version of acute glomerularnephritis

33
Q

Nephrotic syndrome

A
  • this is massive proteinuria (proteins in pee) surpassing the normal level of 3.5g
    -causes hypoproteinema in blood
    -treatment : diet
34
Q

In ___ syndrome, since theres no proteins in blood, liver overproduces ____ which leads to ____.

A

-nephrotic
-lipoproteins
-hyperlipidemia

35
Q

-This syndrome consists of proteinuria and hematuria
-causes acute renal failure and there are three types

A

-Nephritic syndrome
1. pre renal
2.intrarenal
3.postrenal

36
Q

Intrarenal

A

caused by acute tubular necrosis and glomerulonephritis
-treatment- focus on the underlying cause, dialysis,diet
-one should monitor the blood work

37
Q

Prerenal

A

-this can be reversed
-less than 25% perfusion
-happens due to dehydration

38
Q

What are the three stages of infrarenal manifestations?

A
  1. initiation phase
  2. oliguric phase:less urine, hypertension, high BUN,Cr,K &P, and low Na and Ca
  3. polyuric phase: recovering, peeing more
39
Q

What causes acute tubular necrosis and glomerularnephritis?

A

hypotension, nephrotic drugs (NSAIDS), aminoglycosides

40
Q

Chronic Renal failure

A

-seen with diabetes mellitus, lupus
- no symptoms until kidneys lose 75% of function
-symptoms: metabolic acidosis, uremic frost ( too much urea in blood that it shows up on skin)

41
Q

What are the five stages of chronic renal failure based on GFR?

A

Stage I greater than 90 ml/min
stage II 60-89 ml
stage III 30-59 ml
stage IV 15-29
stave V less than 15

42
Q

Which two stages would need dialysis?

A

stage 4 and 5
