Q

What is the most common cause of acute nephritic syndrome?

Study These Flashcards
A

post streptococcal glomerulonephritis

21
Q

what is one of the main causes of secondary HTN?

Study These Flashcards
A

renal artery stenosis

22
Q

which kidney stones are the most common?

Study These Flashcards
A

calcium oxalate stones (75%)

23
Q

these stones most commonly occur due to urea splitting bacteria (these buggers also cause UTIs)

Study These Flashcards
A

Triple Phosphate stones

alkalize the pH of the urine

24
Q

what is the most common cause of acute renal failure?

25
what is one of the most common causes of renal failure in kiddos?
HUS
26
what is the main cause of ARF in developing countries?
HUS
27
this bacteria is the most common cause of HUS, and it also contains what toxin?
E. Coli 0157:H7 | - contains Shiga-like Toxin
28
in regards to renal hypoplasia - what is most common and why?
unilateral lack of development is most common - generally due to ischemia
29
where do horseshoe kidney's generally fuse and what do these patients often times get?
lower pole - often get recurrent UTIs
30
What is the most common location for an ectopic kidney to present?
lower abdomen, pelvis - patient may have duplicate and shorter or longer ureters
31
this condition presents with cysts in the inner medullary and papillary regions (collecting ducts and tubular strictures), cortex is normal - more likely to be symptomatic..
medullary sponge kidney - symptomatic with hematuria and UTIs
32
compare and contrast childhood and adult polycystic kidney disease (PKD)
child: - recessive, asx, fatal - may cause LUNG HYPOPLASIA due to kidney enlargement - LARGE cysts lined by FLATTENED cuboidal epithelium, parenchyma with cartilage adult - dominant, abn collagen/elastin makes a cyst - COMMONLY ASSOC. W. LIVER CYSTS - parenchyma is replaced by large cysts
33
these conditions often have proliferation of mesangial, epithelial and endothelial cells. There is thickening of the BASEMENT MEMBRANE dt deposition of ____ on the epithelial side of the membrane
glomerular disease - anti-GBM
34
what is the most common clinical syndrome associated with glomerular dz?
nephrotic syndrome - proteinuria (>3g/24hr) - generalized edema diseases include: - lipoid nephrosis - membranous glomerulopathy - focal-segmental golmerulosclerosis - bodular and diffuse glomerulosclerosis
35
what is the difference between proliferative and non-proliferative glomerulonephritis?
non-proliferative - often present as nephrotic syndrome, low cell numbers, hypocellularity proliferative - hypercellularity - can progress to end stage renal failure
36
rapidly progressive glomerularnephritis presents with:
goodpasture's syndrome Wegener's granulomatosis
37
this condition presents as: diffuse capillary wall thickening of BM (but NOT hyper plastic) antibody mediated.
membranous glomerulopathy
38
this condition is due to immune complex deposition
membranoproliferative glomerulonephritis
39
this condition presents as irregular thickening of glomerulus BM loops due to hyaline. This is associated with what condition?
nodular sclerosis = Kimmelstiel Wilson Disease - associated with DM * * DM causes glomerulosclerosis that is DIFFUSE or NODULAR
40
this condition appears with pink amyloid, eosinophilic, acellular, homogenous, highly refractive tissues ..
amyloidosis - also can result in glomerulosclerosis - generally DIFFUSE - orbital eccymosis
41
this condition is characterized by gross hematuria with RBC casts, oliguria, uremia, HTN and minimal to NO proteinuria
acute nephritis most commonly caused by post-streptococcal glomerulonephritis
42
which condition shows up as hylanized glomeruli?
chronic glomerulonephritis
43
this condition, primarily a PEDIATRIC condition - has IgA hypersecretion in the vasculature (systemic) and is associated with IgA nephropathy
Henoch-Schonlen Purpura skin bx shows vasculitis
44
which condition presents with immune deposits in capillary loops, increased neutrophils and macrophages and hypercellularity
post-infectious glomerulonephritis
45
which condition presents with diffuse cell proliferation and leukocytic infiltration
post-streptococcal glomerulonephritis
