ACUTE RENAL FAILURE
Acute kidney failure — also called acute renal failure or acute kidney injury — develops rapidly
over a few hours or a few days. Acute kidney failure is most common in people who are already
hospitalized, particularly in critically ill people who need intensive care.
Acute kidney failure can be fatal and requires intensive treatment. However, ARF may be
reversible. If you're otherwise in good health, you may recover normal kidney function.
DEFINITION------An abrupt increase in the BUN and Creatinine with corresponding
problems in handling of fluids, Potassium, Phosphorus, and acid-base balance. This is
usually a greater than 50% decline in the GFR.
It is a sudden fall in renal function characteristic by azotemia.
FOR DIAGNOSIS; raising blood urea nitrogen
Raising creatinine concentration.
Problems with the Definition :
• Serum Creatinine does NOT reflect the degree of renal dysfunction or improvement
• Urine output or lack of may also not reflect the degree of dysfunction
• A better definition may be Acute Kidney Injury (AKI).
Types of Acute Kidney Injury:
Acute Renal Failure can be:
1. Oliguric <400 ml/day
or
2. Non-Oliguric >400 ml/day
Non-Oliguric has a much better prognosis.
-In the Pre-Dialysis Era, ARF had a 50------70% Mortality Rate.
--Today with Dialysis, ARF still has a 50----70% Mortality Rate .

Types of Acute Renal Failure:
ARF
Pre-
Renal
PostRenal
Intrinsic Renal
Vascular
Glomerular
Interstitial Tubular
Phases of Acute Renal Failure:
Initiation Phase-drop in BP, nephrotoxins, early sepsis—rise in BUN/Cr,
decreasing urine output
• Oliguric Phase-usually less than 400 ml/da, may require dialysis
• Recovery/Diuretic Phase-increasing urine output, decreasing BUN/Cr,
Potassium, Phosphorus, and Magnesium .
PRE –RENAL ARF:
A decreasein either total circulatory volume or effective circulatory
volume (I.e. CHF or Sepsis). This leads to activation of the ReninAngiotensin--Aldosterone System and ADH. Thus enhanced Na and
H2O reabsorbtion.
1. CAUSES:
40—60% of cases
Caused by diminution in the renal blood flow
Major causes include:
3
4. ARF –DEFINITION,CAUSES, DIAGNOSIS AND MANAGEMENT 2014 BY DR. MAGDI AWAD SASI
1. GIT loss: DEHYDRATION
Diarrhea, vomiting( what ever the cause--- infection like cholera or organic
obstruction) intraluminal fluid in bowel obstruction ,intraluminal gut fluid , bowel
wall oedema((IBD)),Fistula, Excessive sweating .
2. Sequestration of intravascular volume--- burns ,pancreatitis , sepsis
3. Hepatic: liver cirrhosis , chronic hepatitis
4. Cardiac : CCF , cardiogenic shock , pericardial temponade
5. Hemorrhage: active bleeding with large amount
6. Diuretic phase of ARF or Post-Obstructive Diuresis
7. Medications:
Loop diuretics----frosemide , Bumetanide ,Thiazide diuretic
ACE-I or ARBs---- commonly seen in CCU after few days of treatment.
The prolonged use of diuretic result in loss of concentrating function.
Non oliguric prerenal ARF may also caused by inhibition of the effect of
antidiuretic hormone(ADH/Vasopresin)on the collecting D. BY LITHIUM
CLINICAL FEATURES:
1.History:
Sometimes acute kidney failure causes no signs or symptoms and is detected through lab tests done
for another reason. It is mandatory to look for unexplained symptoms in a patient who had a risk factor
for acute renal injury like organ failure , drug intake , systemic medical illness , HTN or DM.
Symptoms are not specific :
1. CNS symptoms---- syncopy, dizziness , fatigue, confusion,
seizures , coma
2. UROLOGICAL symptoms--- change of urine frequency and
amount ,thirsty
3. H/O fluid loss--- diarrhea , vomiting persistent , bleeding from
orifices
4. H/O Fluid retention, swelling in your legs, ankles --CCF , liver
cirrhosis with ascitis
5.
CARDIAC symtoms--- dyspnea , chest pain
H/O use of diuretics
2.Physical examination:
Postural change in pulse and blood pressure

A large weight loss may indicate volume depletion
Weght gain may accompany intravascular volume loss with total body volume
overload-:-1. SIGNS OF CCF
2. ASCITIS AND OEDEMA
3. CHRONIC STASIS DERMATITIS
4. ULCERS IN THE LOWER LIMBS
Hemodynamic – persistent low pulmonary capillary wedge pressure suggests
hypovolemia where as raising or high PCWP suugests CCF and under perfusion.
In a pt with cardiac or pulmonary disease , hemodynamic monitoring plays a rule in
diagnosis.
WHAT ARE THE DIAGNOSTIC CRETERIA?
I.
II.
III.
IV.
Signs of volume depletion or third space fluid loss
Volume depletion by hemdynamic criteria such as pulmonary capillary wedge pressure.

put with normalization of urinary indices
No evidence of obstruction on ultrasound abdomen if oliguric stage persists.
V.
POST-RENAL ARF
Cause :
2---25% ARF cases .
Generally , the patient is oliguric or anuric.
Due to changes in the obstructing lesions with the patients position, there may be
wide variety in urine out put.
1 .Intrauretric obstruction:
Stones , blood clots ,pus ,tissue papillary necrosis—DM ,Analgesic drug excess

ACUTE TUBULAR NECROSIS
Pathophysiology---Hypoxia of the tubular microvasculature leads to tubular necrosis and loss of reabsorbtion
and secretory abilities of the tubules .
Afferent and Efferent Arteriolar Vasoconstriction
• Mesangial Contraction WITH Release of Reactive Oxygen species, NO, ATII, PG’s,
Catecholamines
• Tubular Necrosis due to tubular obstruction and back-leak With Cellular Edema
• Increased free Ca++ WITH Release of compartmentalized enzymes
• Destruction in Cytoskeleton
• Reperfusion injury from reactive Oxygen species, WBC’s, Complements, and
cellular debris
TYPES OF ATN:

ISCHEMIC TUBULAR NECROSIS :
Hypotention
Surgery ---cardiovascular or abdominal surgery.
Sever burns
Sever muscle injury or extreme physical exertion.
Sepsis , aortic cross –clamping
Prerenal azotemia .
B.TOXIC TUBULAR NECROSIS:
Substances, such as medicines that are toxic to the kidneys. Many substances that are not
toxic to the kidneys in a healthy person may become toxic in a person who has existing kidney
problems or another condition that increases his or her risk of acute renal failure, such
as heart failure, diabetes, or multiple myeloma.

DIAGNOSTIC FEATURES:
1RY Parenchymal disease---.Urinanalysis
.Severe hypertension is common
.No evidence of obstruction on USS abdomen
No signs ,symptoms, hemodynamic indications of ongoing hypovolemia or persistent
ARF following correction of hypovolemia.
Urinalysis and laboratory finding
No evidence of obstruction
No response to volume repletion
CLINICAL FEATURES:
History---1. H/O URTI suggests post infectious glomerulonephritis
Fever , rash or pleuritic pain may point to vasculitis
2. H/O drug intake
NSAID ,ANTICOAGULANTS ,ANTIBIOTIC ,CIMETIDINE ,DIURETIC, CYCLOPHOSPHAMIDE,
METHOTREXATE, AMINOGLYCOSIDE, RADIOLOGIC CONTRAST MATERIAL.
3. H/O sepsis --- once there is no cause
4. H/O blood transfusion--- hemolysis ,transfusion reaction ,microangiopathic hemolysis
5. Rhabdomylosis---unconscious or seizures. Hypokalemia/hypophosphatemia cause it.
6. Examination may find evidence of vasculitis.
Rashes are often present. Sclerodectaly---scleroderma HTN---85%
7. H/O preexsisting prerenal azotemia may point to progression to ATN.
8. Hypotension does not need to be documented in postsurgical patient ,60 year in
order for the physign to suspect ATN
RECOMMENDED DIAGNOSTIC APPROACH:
i.
Urinalysis:
Red blood cell casts -----evaluate autoimmune disease
ii.
Urine osmolality –(Uosm)
Specific gravity of limited value in ATN (affected by glucose or protein).
1. Pre-renal--- 90% have Uosm more than500mosm/l
2 .Post renal ARF --- INITIAL like prerenal azotemia
Persistent obstruction ---- tubular damage---low Uosm
9
10. ARF –DEFINITION,CAUSES, DIAGNOSIS AND MANAGEMENT 2014 BY DR. MAGDI AWAD SASI
iii.
3. ATN—90% have Uosm less than 350 mosm/l
Loss of the concentrating ability with tubular dysfunction
4.Uosm/Posm:
The overlap range (Uosm 350 to 500 mosm/l) is not diagnostically useful.
90% of patients with ATN have Uosm/Posm less than 1.07
90% of patients with prerenal azotemia have Uosm/Posm more than 1.25
BUN and creatinine:
1. Creatinine---with complete cessation of glomerular filtrate , serum creatinine
increase by a bout 1mg/dl/day
Daily increase is less in patients with decreased muscle mass( older)
More 2.5mg/dl/day in young muscular males.
2. Urea:
Urea is freely filtred and variably absorbed.
Reabsorption is proportional to water flow in tubules ,the presence of ADH ,
local tubular damage, peritubular blood flow.
Production of urea is affected by hepatic disease
Decrease BUN-- LOW PROTEIN DIET
STARRVATION
HEPATIC FAILURE
Increase BUN ( hypercatabolism)--
BURNS
SEPSIS
INFECTION
GLUCOCORTICOID USE
TRAUMA
POSTSURGICAL
The rate of BUN rises with complete recession of glomerular filtration --- 24-60mg/ml/d
IV -- plasma BUN/creatinine ratio:
Routine urea is increased greatly in prerenal and post renal uremia.
BUN/Creatinine ratio more than 20/1 is present in 80% of renal and postrenal
azotemia.
Intrarenal ARF &ATN are characterized by proportionate BUN/ CRET 10/1

11. ARF –DEFINITION,CAUSES, DIAGNOSIS AND MANAGEMENT 2014 BY DR. MAGDI AWAD SASI
V-- URINE CREATININE:
1. Urine creatinine :
Is a marker of ability to concentrate urine as creatinine is filtred without reabsorption
2. Ucreatinine /P creatinine
˂
10----------85% of pt with ATN
˂
20------85% OF PT with prerenal ARF
VI --Urine sodium (U Na):
1. The ability to conserve Na in proportional to the amount filtered is a marker of intact
tubular function .
2. UNa ˂
20meq /l occurs in 90% of prerenal azotemia
˂ meq/l is found in 90% of pt with ATN
40
VII—Fractional exertion of sodium( EF Na)
1.A more sensitive test is the calculated EF Na
U Na /P Na x P creat /U creat
2. 90% of prerenal azotemia
90% of ATN
˂
1%
˂
2%
3. EF Na less than 1%
Common in renal parenchymal disease ,particularly glomerulonephritis as tubules
retain function and attempt to compensate in response to diseased glomeruli.
VIII Other laboratory tests:
1. A clue to presence of tubuloischemic necrosis ----------- hyperchloremic acidosis of
rapid onset
2. Myoglobin levels in urine may confirm rabdomyolysis
3. A SEVER ANION GAP METABOLIC ACIDOSIS WITH OXALATE CRYSTALS IN URINE
MAY INDICATE ETHYLENE GLYCEROL TOXICITY.
4. Hyperchloremic acidosis with hyperkalemia--- 80% of pt w post obstructive
dieresis

IX ULTRSOUND:
1. 85% of case , the cause of obstruction can be detected by USS (ureter,kidney,pelvis)
2. If the index of suspicion of obstruction is high (single kidney , kidney transplant
,abdominal mass), retrograde pyelogram may be indicated.

SUMMARY OF INITIAL EVALUATION:
a. Consider possible etiologies and direct evaluation
b. Medications should always be suspected
c. Standard Blood Testing :
a. Electrolyte/renal panel, Ca2+, Phosphate, Mg2+, Albumin
b. Complete Blood Count
c. Foley catheter to rule out bladder obstruction AND take sample of urine.
1. Urine for electrolytes, dipstick and microscopic analysis
a. Osmolality, creatinine, Na+, K+, Clb. Urine spot protein to creatinine ratio (normal is <0.2)
c. Pigment: Hemoglobin (myoglobin)
d. Cells, Casts, Crystals, Organisms
e. Consider Urine culture
2. More informative for the cause:
i.
Renal/Pelvic Sono - stones, hydronephrosis, mass
ii.
Consider Abdominal radiograph if ultrasound is not done to rule out stones
iii.
ESR, ASO titer, ANA, C3/C4 Anti-GBM Abs
iv.
Renal Biopsy in rapidly progressing disease
v.
ANCA and Anti-GBM diseases - consider cyclophosphamide + glucocorticoids
vi.
Idiopathic rapidly progressive glomerulonephritis often ANCA positive (other
inflammatory diseases such as bacterial endocarditis can given ANCA+)
WHAT OTHER THE DIFFERENT TYPES OF GN?(( pathological))
1. Glomerular Involvement :
14
15. ARF –DEFINITION,CAUSES, DIAGNOSIS AND MANAGEMENT 2014 BY DR. MAGDI AWAD SASI
a. Diffuse: all glomeruli in a section are diseased
b. Focal: some glomeruli in a section are diseased
c. Segmental: parts of individual glomerulus affected
2. Focal Glomerulonephritis:
a. Some glomeruli are dead( necrosis, collapse, sclerosis ).
B .Acute or chronic inflamation is often seen.
3. Crescent Glomerulonephritis (very poor prognosis)
Crescent (moon shaped) formation in glomerulus
Affected glomeruli are non-functional
Focal and Segmental Glomerulosclerosis: portions of many glomeruli are destroyed
5. Minimal Change Glomerulonephritis :
Glomeruli appear okay, but function is poor
Electron microscopic evidence of basement membrane disease
Response to glucocorticoids is usually very good
6. IgA Deposition:
IgA nephropathy
Deposition of IgA immune complexes
Differential includes Systemic Lupus (SLE) and Henoch-Schonlein Purpura (HSP)
7. Proliferative Glomerulonephritis
Increase in mesangeal cell number
Usually follows insults (eg. Post-Streptococcal)
May be seen in collagen vascular disease, SLE.
8. Collapsing Glomerulonephritis
Major form seen in HIV nephropathy
Usually late stage
Rapid progression to renal failure (weeks-months)
No effective therapy to date

16. ARF –DEFINITION,CAUSES, DIAGNOSIS AND MANAGEMENT 2014 BY DR. MAGDI AWAD SASI
9.
Tubular Necrosis
Tubular cells die and slough off basement membrane
The dead tubular cells form casts which can occlude lumen
Glomular basement membrane may also be damaged
MANAGEMENT OF ARF:
A. Renal Diet :
Low phosphate, potassium, sodium, and protein
High calcium and vitamin D diet
Various multivitamin formulas available for renal patients, eg. Nephrovit®.
Low protein diet may slow progression slightly in chronic renal disease
Phosphate and Calcium
Dangerous if product of Calcium and Phosphage > ~70 (mg/dl) (will lead to
precipitation)
If product is close to 70, then phosphate should be lowered with aluminum
compounds
These compounds should be given with meals to bind the phosphate directly
If product is <60, then calcium should be given 500-1000mg po tid with meals
If calcium is low but phosphate normal, then calcium should be given before meals
Consider using 1,25 dihyroxyvitamin D supplements
B. AVOIDABLE COMPLICATIONS SHOULD BE FOLLOWER.
16
17. ARF –DEFINITION,CAUSES, DIAGNOSIS AND MANAGEMENT 2014 BY DR. MAGDI AWAD SASI
1.Acidosis
Renal tublar acidosis (RTA) is common in early renal failure
Oral bicitra (citrate replaces bicarbonate) may be used
Bicitra is contraindicated in edematous states due to high sodium content
2.Hyperuricemia
Check uric acid levels
Uric acid deposition in renal tubules may worsen progression of renal failure
Allopurinol may be given (100-200mg po qd) to attempt normalization of uric acid
3.Hypertension
ACE inhibitors generally contraindicated in moderate to severe renal failure
Calcium blockers such as nifedipine can be used.
Labetolol is also very effective but patient should have LV EF>50% and no
bronchospasm
Consider Hydralazine for afterload reduction
Pure alpha-adrenergic blocking agents may be effective, but tachyphylaxis may occur
Diuretic improve hypertension/ volume overload
4. Volume overload
Attempt to maximize cardiac output and improve intravascular volume
Diuretics often worsen renal failure but may be necessary to prevent pulmonary
edema
In general, potassium sparing diuretics should be avoided (high risk hyperkalemia)
Dopamine or mannitol can be tried, but are usually not effective
Albumin infusions are probably not helpful, but may help diuresis in low albumin states
Dialysis may be required particularly in severe volume overload situations
5. Protein Load
Reducing protein load is thought to reduce azotemia .
Appears to slow progression of CRF.
Patients with moderate renal disease - some decrease in progression on low protein
diet .
Patients with severe renal disease show no benefit on low protein diet .
Hospital inpatients with ARF ~50% mortality rate.
6.Newer Agents

C. Volume Overload
Hemofiltration or hemodialysis can be used to allow recovery of kidney after ARF
Average duration of need for these therapies was 9 days in ARF
After this time, kidneys regain function and increase urine output
Native kidneys may continue with minimal function for 6-12 months of hemodialysis
After that, native kidneys usually shut down permanently
D. Kidney Transplantation
Excellent (and improving) results with cadaveric grafts.
Living Related Donor kidneys superior to CRT
New kidney usually placed in extraperitoneally in the pelvis
Cyclosporin ,Prednisone, OKT3, mycophenolic acid, FK506 immunosuppression
Combined Kidney Pancreas transplant in Diabetic ESRD patients
