Chronic Kidney Disease

  1. 1. Hamza J. AlGhamdiSupervised by:Prof. Mohammed Alhomrani
  2. 2. contentsIntroduction Examination Investigation epidemiology History Management Conclusion
  4. 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. 5. StagesStage 1 disease is defined by a normal GFR (greater than 90 mL/min per1.73 m2) and persistent albuminuriaStage 2 disease is a GFR between 60 to 89 mL/min per 1.73 m2 andpersistent albuminuriaStage 3 disease is a GFR between 30 and 59 mL/min per 1.73 m2Stage 4 disease is a GFR between 15 and 29 mL/min per 1.73 m2 Stage 5disease is a GFR of less than 15 mL/min per 1.73 m2 or end-stage renaldisease
  7. 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. 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.
  9. 9. By the end of 2008, therewere 10,203 patients onhemodialysis

  36. 36. Urinalysis • 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 HTN . Indicated in patient with DM .
  37. 37. Other Investigations• Chest X-ray • pulmonary edema• ECG May show abnormalities associated with electrolyte • Normal disturbance in CKD• Renal Ultrasound • Small kidneys, No obstruction, No stones• Others • ?????????
  38. 38. Management• Admission to MFS unit• Investigations• Fluid restriction• Sliding scale (Glucose monitoring)• Foley’s catheter• Dietary modification: • Protein restriction • Potassium restriction • Phosphorus restriction • Diabetic diet
  39. 39. Management• Drugs: • Replacement therapy • Iron 200 mg PO BID • Folic acid 5 mg PO OD • CaCO3 • 1-alpha What if the patient has • Hypertensive drug Hyperkalemia ?? • Captopril 50 mg PO BID • Pantazole 40 mg PO OD
  40. 40. Management• Education about hemodialysis• Referal for Radiology for Permacath insertion• Preparation for hemodialysis
  41. 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).
