Q

What are the signs of acute tubular necrosis?

A

early oliguria followed by recovery of renal function with an increase in renal
output. GFR, however, may remain low due to tubular damage. Full renal
capacity is usually regained within 6 weeks of the initial stressor.

Q

What does wegener’s granulomatosis do to the kidenys?

A

Antineutrophil cytoplasmic antibodies
(ANCAs) attack small to medium-sized blood vessels resulting in necrotizing
granulomatous inflammation.

Q

What is Goodpasture’s disease?

A

Goodpasture’s
disease (B) is due to a type 2 autoimmune reaction with antibodies attacking
the glomerular basement membrane and lung membrane. Patients often
present with upper respiratory tract complaints such as haemoptysis with renal
manifestations, such as anaemia and glomerulonephritis, occuring later.

24
Q

Whats is posr streptococcal GN?

A

usually associated with haematuria and hypertension
following a streptococcal infection which leads to an acute nephritis due to
deposition of immune complex

25
what is the investigation for detecting diabetic nephropathy?
microalbumin in the urine
26
Is serum creatinine an early or late marker of renal function?
Elevation in serum creatinine (C), which is usually excreted by the kidney, is a late marker of function renal impairment and not appropriate for early risk identification
27
What do you find on electron microscopy in minimal change disease?
fusion of the podocyte foot process. Pododcyte effacement
28
Other than nephrotic syndrome what can minimal change disease present with?
eczema and asthema
29
What can sustained hyperphosphataemia cause in the vascular structure?
Vascular calcification
30
how do you treat hyperphosphataemia?
phosphate binders--> sevelamer it bind to phosphates in the Gut and lowers the serum phosphaste level it also lowers calcium and cholesterol
31
Why do we give phosphates bilders before Vitamin D in those with 2nd hyperparathyroidism?
Vitamine D increases calcium and phosphate reabsorption and so can inadvertently exacerbate the patient’s symptoms.
32
Can you get parechymal gas accumulation in pyelonephritis?
Parenchymal infection | results in gas accumulation which is identifiable on CT scan
33
Does renal stone cause renal infections?
they are rarely coincident with renal infection as suggested by the urine dipstick But the obstruction can lead to infections
34
what is Kimmelstiel-Wilson lesion associated ith?
Diabetic nephropathy; glomerulosclerosis
35
What is a red cell cast
RBC that have gotten into the renal tubules. It is a strong indication of glomerular pathology
36
Explain the pathophysiology of diabetic nephropathy
an initial increase in glomerular filtration rate and glomerular basement membrane hypertrophy. As the disease progresses, glomerulosclerosis occurs as a result of accumulation of extracellular matrix and destroying the filtering ability of the glomerular membrane. This allows protein leakage.
37
clinial test results of renal failure?
oliguric | raised urea and creatinine
38
UTI clinical test result?
dysuria rised WBC leucocytes and nitrites (bacterias convert nitrates to nitrites)
39
Triad of nephrotic syndrome?
Proteinuria (>3g/24hrs) hypoalbuminaemia (<25g/L) hyperlipidaemia
40
1st line treatment of nephrotic syndrome?
fluid restrict sodium restriction diuretic (furosemide)
41
How does ACE-I protect against protinuria?
It reduces filtration pressure on the glomerular capillaries.
42
The disadvantage of US KUB
KUB US scan is poor at differentiating different | stones and can often miss smaller stones.
43
Symptons of tuberculosis on the kidneys?
Insidious symptoms. Pain in the back, flank and suprpubic region Haematuria, frequency and noicturia Most patients with renal TB have sterile pyuria, which can be accompanied by microscopic hematuria.
44
What is the classic presentation og bladder cancer?
Painless haematuria
45
The triad of renal cell carcinoma?
haematuria, flank pain flank/abdo mass weight loss, fever, malaise Anaemia from impaired erythropoiesis (SOB, pallor)
46
what is post streptococcal GN
part of the nephritic syndrome Patients usually suffer from a streptococcal infection 1–3 weeks prior to presenting with the symptoms or signs of the nephritic syndrome. During this time, immune complexes are formed and deposited in the glomeruli causing damage.
47
Symptoms of hypercalaemia
abdo pain depression constipation
48
Presentation of polycyctic kidney disease
loin or abdo pain | symptoms of renal failure
49
What are vascular findings of PKD?
mitral valve prolapse | berry aneurysms
50
what is a medullary sponge kidney?
a congenital disorder of the kidneys that is characterized by the formation of cystic sacs within the papillary zone of the kidney creating a sponge-like appearance.
51
what does a medullaty sponge kidney predispose you to?
The cysts create an obstruction that prevents the optimal flow of urine through the renal tubules, predisposing to UTIs, haematuria and renal calculi. hemihypertrophy, hypercalciuria and renal tubular acidosis
52
what do hotse shoes kidney cause?
UTI, renal stones
53
What is analgesic nephropathy?
From chronic NSAIDs consumption Papillary necrosis and tubulointerstitial nephritis. Anaemia, UTI and haematuria
54
Acute hyperuricaemice nephropathy
A result of hyperuricaemia, common in patients with increased cell turnover, such as those with myeloproliferative disorders after chemo. Uric acid crystallizes within in the renal system causing obstructions--> flank pain, oliguria, hypertension and oedema.
55
symptoms of hypoglycaemia?
sweating, tachycardia, palpitations and tremor.
56
Triads of goodpasture's disease?
glomerulonephritis, pulmonary haemorrhage and anti-GBM a type 2 autoimmune reaction, attach on type 4 collagen of the lungd and glomerulus.
