Renal Flashcards
Most common site of obstruction causing Hydronephrosis in fetus
Ureteropelvic junction
POTTER syndrome associated with
- Pulmonary hypoplasia
- Oligohydramnios
- Twisted face
- Twisted skin
- Extremity defects
- Renal failure in utero
Multicystic dysplastic kiney is due to
Abnormal interaction between ureteric bud and metanephric mesenchyme
Renal clearance C=
UV/P
GFR=
Uinulin x V/Pinulin = Cinulin
Effective renal plasma flow (ERPF) estimated using
PAH
Filtration Fraction (FF) =
GFR / RPF
Affect of Prostaglandins on Afferent arterioles
Dilate
Increase RPF
Increase GFR
Angiotensin 2 affect on Efferent arterioles
Constrict
Decrease RPF
Increase GFR
Increase FF
Afferent arteriole constriction causes
Decrease RPF
Decrease GFR
Efferent arteriole constriction causes
Decrease RPF
Increase GFR
Increase FF
An increase in Plasma protein concentration causes
No change of RPF
Decrease GFR
Decrease FF
Decrease in Plasma protein concentration causes
no change on RPF
Increase GFR
Increase FF
Hartnup disease is
AR deficiency of Neutral Amino Acid (Tryptophan) transporters in PCT
Hartnup disease leads to
Pellagra-like:
Dermatitis
Diarrhea
Dementia
Fanconi syndrome is
Renal tubular defect that causes reabsorptive defect in PCT
Fanconi syndrome leads to
- Metabolic acidosis
- Wilson
- Ischemia
- Nephrotoxins
Bartter syndrome is
AR renal tubular defect causing reabsorptive defect in TAL
Bartter syndrome leads to (3)
- Hypokalemia
- Metabolic alkalosis
- Hypercalciuria
Gitelman syndrome is
AR renal tubular defect causing reabsorptive defect of NaCl in DCT
Gitelman syndrome leads to
Hypokalemia
Metabolic alkalosis
Liddle syndrome is
AD renal tubular defect causing an increased Na reabsorption in Distal and CT
Liddle syndrome leads to (4)
- HT
- Hypokalemia
- Metabolic alkalosis
- Decrease aldosterone
FABulous Glittering Liquid
- FAnconi: PCT
- Bartter: TAL AR
- Gitelman: DCT AR
- Liddle: CT AD
What shifts K out of cell causing Hyperkalemia
DO Insulin LAβ
- Digitalis
- HyperOsmolarity
- Insulin
- Lysis of cells
- Acidosis
- β-adrenergic antagonist
Low serum Na cuases (4)
- Nausea
- Malaise
- Stupor
- Coma
High serum Na causes (3)
- Irritability
- Stupor
- Coma
Low serum K causes (4)
- U wave on EKG
- Flattened T wave
- Arrhythmia
- Muscle weakness
High serum K causes (4)
- Wide QRS
- Peaked T wave
- Arrhythmia
- Muscle weakness
Low serum Ca causes (3)
- Tetany
- Seizures
- QT prolongation
