Kidney Flashcards
Polycystic Kidney Disease (PKD) is
Inherted defect leading to bilateral enlarged kidneys with cysts in the renal cortex and medulla
AR PKD present in
Infants as worsening renal failure and HT
AR PKD is associated with
Congenital hepatic fibrosis
Hepatic cysts
AD PKD is a mutation in
APKD1 or APKD2 genes
AD PKD associated with
Berry aneurysm
Hepatic cysts
MVP
Medullary Cystic Kidney Disease genetics
AD defect leading in cysts in the medullary collecting ducts leading to parenchymal fibrosis
Acute Tubular Necrosis is
Injury and necrosis of tubular epithelial cells
What is seen in the urine in ATN
Brown, granular casts that are dead tubular epithelial cells
What part of kidney is most susceptible to ischemic damage in ATN
Proximal tubule and medullary segment of the thick ascending limb
What causes Nephrotoxic ATN
- AG
- Heavy metals
- Myoglobinuria
- Ethylene glycol
- Urate
Acute Interstitial Nephritis is
Drug-induced hypersensitivitiy involving the intertitium (CT b/w tubule) and tubules resulting in ARF
What causes Acute interstitial nephritis
NSAIDs
Penicillin
Diuretics
Renal papillary necrosis is
Necrosis of renal papillae with hematuria and flank pain
What causes Renal Papillary necrosis
Chronic analgesic abouse
DM
Sickle cell
Pyelonephritis
Nephrotic syndromes result in
- Hypoalbuminemia: pitting edema
- Hypogammaglobulinemia: Increase infections
- Hypercoagulable state: loss of AT3
- Hyperlipidemia and Hypercholesterolemia: fatty casts in urine
Minimal change disease is associated with
Hodgkin Lymphoma
Only change in Minimal Change disease
Effacement of foot processes (fat droplets) on EM
Focal segmental glomerulosclerosis (FSGS) is
Nephrotic syndrome with focal and segmental scerlosis
