4. What is CKD ?
• Also known as Chronic Renal Failure.
• It is defined by either a pathologic abnormality of the kidney, such as
hematuria and/or proteinuria, or reduction of GFR of <60
mL/minute/1.37 m^2 for >3 months duration.
Proteinuria
and/or GFR < 60
Hematuria
For 3
Months
5. Stages
Stage 1 disease is defined by a normal GFR (greater than 90 mL/min per
1.73 m2) and persistent albuminuria
Stage 2 disease is a GFR between 60 to 89 mL/min per 1.73 m2 and
persistent albuminuria
Stage 3 disease is a GFR between 30 and 59 mL/min per 1.73 m2
Stage 4 disease is a GFR between 15 and 29 mL/min per 1.73 m2 Stage 5
disease is a GFR of less than 15 mL/min per 1.73 m2 or end-stage renal
disease
7. Epidemiology
• Common condition
• Often unrecognized until advanced stages.
• It is estimated that 10% of the adult population world wide will have
CKD
• Incidence is raising
• Due to different factors (aging population, increased incidence of DM
& HTN, Increased incidence of glomerular diseases …….)
8. Epidemiology
• conclude that prevalence of CKD in
the young Saudi population is
around 5.7%
• Only 7.1% of the CKD patients were
aware of their CKD status
• 32.1% were told that they had
protein or blood in their urine and
10.7% had known kidney stones in
the past.

2008, there
were 10,203
patients on

• Screening test to determine for
pathologic markers of kidney
damage excreted in the urine
• Microalbuminurea is a risk factor for
development of progressive CKD
and CAD associated with DM and

.

• Normal disturbance in CKD
• Renal Ultrasound

• 1-alpha
What if the patient has
• Hypertensive drug
Hyperkalemia ??
• Captopril 50 mg PO BID
• Pantazole 40 mg PO OD
40. Management
• Education about hemodialysis
• Referal for Radiology for Permacath insertion
• Preparation for hemodialysis
41. Hemodialysis
• method for extracorporeal removing
waste products such as creatinine
and urea, as well as free water from
the blood when the kidneys are in
renal failure. Hemodialysis is one of
three renal replacement therapies
(the other two being renal transplant;
peritoneal dialysis).
