Q

What is the effect of problem in excretory function of kidney?

A

 Retention of toxin and products of metabolism Such as ammonia, urea, uric acid, creatinine in renal failure result in ammonia smell (halitosis), urea frost “skin”.

“Ammonia smell due to retention of urea”

Q

What is the effect of problem in hemopoitic function of the kidney?

A

Anemia due to :
1- Decreased erythropiotin production “MCQ”
2- Malnutrition
3- Blood loss in patient with hemodialysis causes iron deficiency anemia
4- Toxins that depress bone marrow

Q

What is a clinical presentation related to micturition and urine output?

A

1- Volume:
 Normal:1.2-2L/day
 Polyuria>2000ml/day
 Oliguria<500ml/day
 Anuria: total suppression of urine , < 100ml/day

2- Color :
 Red urine seen mainly in hematuria , hemoglobinuria which could be differnitated by microscopic examination which can demonstrate RBCs in case of hematuria but not in case of hemoglobinuria.

“The Presence of red urine doesn’t necessarily indicate blood”

3- Dysuria : “‏التهاب”
 Painful urination
 Urinarytractinfectionsareacommoncause.

4- Frequency .

Q

What are the investigations done to kidney?

A

Biochemical Investigations

Renal Function Tests

Radiologic Examination

Renal Biopsy

17
Q

What are the biochemical investigations done to the kidney?

A
  1. Examination of urine = urine analysis :
     Physical
     Chemical
     Microscopic
  2. Tests for kidney functions
  3. Microbiologic and immunologic tests
18
Q

What are the renal function tests done to the kidney?

“Creatinine, bun & PU and GFR”

A

1- Serum creatinine : normally .6-1.2 mg/dl

2- Serum Plasma urea and Blood Urea Nitrogen (BUN) : urea normally 15-40 mg/dl , while BUN 8-13 mg/dl
“Not very Acc.”

3- Glomerular Filtration Rate (GFR) :
- Best measure for kidney function
- Calculated by serum creatinine
- No direct way to calculate GFR

19
Q

What are radiologic examination of the kidney?

A
  • Of the kidney and the urinary tract by ultrasound
20
Q

What is the normal range of proteins in urine?

A
  • Urine normally contain only small amount of protein (<150 mg/24 h)

“Less than tenth gram”

21
Q

What are the grades of proteinuria?

A

1- Micro-albuminuria : 30-300 mg/day = 20=200 ug/min

2- Mild proteinuria : < 1000 mg/day

3- Moderate proteinuria : 1000-2000 mg/day

4- Heavy proteinuria : >2000 mg/day

5- Nephrotic range proteinuria : > 3500 mg/day

22
Q

What are the types of hematuria?

A

a) Microscopic hematuria : diagnosed by urine dipstick, color of urine not changed

b) Macroscopic hematuria : blood is visible in urine , usually originate from lower urinary tract dse. as stone , carcinoma of bladder.

23
Q

What is the definition of acute kidney injury?

A
  • rapid deterioration of parenchymal renal function , may cause uremia.
24
Q

What are the characteristics of acute kidney injury?

A
  • Usually but not invariably reversible
  • Usually but not invariably cause oliguria
25
Q

What is the definition of chronic kidney disease?

A
  • deterioration of kidney function for more than 3 months
26
Q

What are the stages of chronic kidney disease?

A

 Kidney damage with normal or increased GFR
 Kidney damage with mildly decreased GFR
 Moderately decreased GFR
 Severely decreased GFR
 Kidney Failure

≥ 90

27
Q

What are the characteristics of nephrotic syndrome?

A

 Edema
 Proteinuria
 Hyper-lipidemia
