consequence of oligohydroaminos
potter sequence
flat face
low set ears
defects of extremeties
which is non inherited cystic disease
dysplastic kidney
which gene defect is seen in polycystic kidney disease
APKD1 and APKD2
which PKD happens in children
autosomal recessive
symptoms of portal hypertension due to fibrosis and oligohydramnios seen
what is the common cause of death in PKD in adults
berry aneurysm
how to differentiate medullary cystic kidney disease from PKD
shrunken kidneys seen in MCK
most common cause of pre renal azotemia?
decreased blood flow
in which congenital disease there is high conc of renin in blood
autosomal dominant PKD
long standing post renal azotemia leads to?
tubular damage which results in decreased reabsorption
most common cause of acute renal failure?
acute tubular necrosis
what happens to GFR in acute tubular necrosis
decreases
2 reasons of acute tubular necrosis
ischemia due to long standind pre renal azotemia
nephrotoxic
which parts of kidney is susceptible to damage due to ischemia
PCT
ascending thick limb
causes of necrosis of tubules
aminoglycosides heavy metals myoglobinuria from injury to muscle ethylene glycol: oxalate crystals seen in urine radiocontrast dye urate
most common cause of necrosis of tubules in acute renal failure
aminoglycosides
can renal tubular cell regenerate
yes they are stable cells. it takes time but necrosis can be reversed
oliguria can persist for how many weeks in acute tubular necrosis before it is recovered
3 weeks because tubular cells are stable cells
reason for acute interstitial nephritis
drug induced hypersensitivity
infection or sarcoidosis
acute interstitial necrosis lead to what disease
renal papillary necrosis
causes of renal papillary necrosis
diabetes acute interstitial nephritis chronic use of pain killer sickle cell trait acute pyelonephritis
risk factors for UTI
females pregnancy sexual intercourse urinary stasis catheter
symptoms of cystitis
dysuria
suprapubic pain
urgency and increased freq of urination
absent systematic signs
diagnosis of cystitis?(lower UTI)
cloudy urine with greater than 10 WBC
dipstick shows positive leukocyte esterase and nitrites
greater than 100000 colony forming unit
what is the gold standard diagnosis for lower UTI
greater than 100000 colony forming unit
