Renal8 Flashcards
1
Q
Renal Tubular Acidosis (RTA):
- Type 1 (distal)
A
- Defect in collecting tubules ability to excrete H+
- Urine pH > 5.5
- Hypokalemia
- Increased risk for Calcium Phosphate kidney stones (d/t High urine pH & bone resorption)
2
Q
Renal Tubular Acidosis (RTA):
- Type 2 (proximal)
A
- Defect in Proximal Tubule HCO3- reabsorption
- Fanbule
- Fanconi’s syndrome
- Urine pH < 5.5
- Hypokalemia
- Increased risk for hypophosphatemic rickets
3
Q
Renal Tubular Acidosis (RTA):
- Type 4 (hyperkalemic)
A
- Hypoaldosteronism or
- Lack of collecting tubule response to Aldosterone
- Hyperkalemia impairs ammoniagenesis in proximal tubule
- Low buffering capacity
- Low urine pH
