Flashcards in Data - Renal Deck (12):
Relevance of plasma urea/creatinine ratio?
Levels increase as GFR decrease
Not a reliable measure of kidney function
eGFR in stages of chronic kidney disease?
CKD: (eGFR measured in ml/min/1.73m2
Stage 1: eGFR >90 with kidney damage
Stage 2: eGFR 60-90
Stage 3: eGFR 30-60
Stage 4: eGFR 15-30
Stage 5: eGFR <15
What happens to potassium in renal disease?
Increased K+ occurs in acute and chronic renal disease
What happens to bicarbonate in renal disease?
Decreases commonly in acute and chronic kidney disease
What happens to calcium and phosphate in renal disease?
Calcium decreases (impaired vit D3 activation)
What happens to urate in renal disease?
Increases in CKD (not in gout)
Increased alkaline phosphatase and parathyroid hormone?
Can be due to secondary hyperparathyroidism related to decreased calcium and increased phosphate
Causes of proteinuria?
Causes of painful haematuria?
Renal stones (with obstruction)
Causes of painless haematuria
Lots of other renal problems
Difference between nephrogenic and cranial diabetes insipidus?
Usually genetic mutation in tubular AVP receptor
Lack of AVP produced from pituitary
