2
Q
ACUTE TUBULAR NECROSIS
- Affected part
- Cause
A
- Damage to renal tubular cells
2. Ischemia or toxic agents
3
Q
FINDINGS IN ACUTE TUBULAR NECROSIS
A
Microscopic hematuria
Proteinuria
RTE cells, RTE casts
Hyaline, granular, waxy, and broad casts
4
Q
ETIOLOGY: Fanconi Syndrome
A
Generalized failure of tubular reabsorption in the PCT
5
Q
NEUROGENIC vs NEPHROGENIC DI
A
NEUROGENIC - failure of the hypothalamus to produce ADH
NEPHROGENIC - renal tubules fail to respond to ADH
6
Q
FINDING IN DIABETES INSIPIDUS
A
Low sepcific gravity
Polyuria (>15L/day)
7
Q
ETIOLOGY: Renal Glucosuria
A
Defective tubular reabsorption of glucose
8
Q
FINDING IN REANL GLUCOSURIA
A
Glucosuria (Normal blood glucose, increased urine glucose)
