Study Notes
Pathophysiology Questions
-
Acute Renal Failure (ARF) - Humoral Syndrome Manifestations:
- Hyperazotemia
- Oliguria (Low urine output)
- Hypokalemia (low potassium)
- Hyponatremia caused by hemodilution
-
Diuresis Changes in Hyperglycemia:
- Osmotic diuresis caused by excess glucose in the urine increases urine production.
- Kidney function can be impaired with damage to the glomeruli by hyperglycemia
- Hormonal changes such as alteration in vasopressin production can affect sodium and water balance and urine output
-
Obstruction of Urinary Pathways:
- Increased pressure leads to impaired filtration and backflow of urine
- Hormonal changes are also a factor
-
Chronic Renal Failure (CRF) Manifestations:
- Osteodystrophy
- Iron deficiency anemia
- Secondary hyperparathyroidism
- Osteoporosis
-
Acute Renal Failure (ARF) Prerenal Causes:
- Systemic vasodilation in spinal shock
- Heart failure
- High levels of catecholamines in the blood
Additional Pathophysiology Questions
-
Reduced Glomerular Filtration Rate (GFR) Consequences:
- Fluid and Electrolyte imbalances
- Waste product accumulation
- Hypertension (high blood pressure)
- Anemia (low red blood cells)
- Bone disease
- Cardiovascular disease.
-
Urinary Pathway Obstruction Consequences:
- Hydronephrosis
- Renal failure
- Urinary tract infections
- Stone formation
- Pain and discomfort
- Urinary incontinence.
-
Glomerulopathy with Nephritic Syndrome:
- Increased blood pressure is caused by activity of RAAS, increased extracellular fluid, defects in endothelial function and inflammation
- Genetic factors also play a role.
-
Nephrotic Syndrome Coagulopathy:
- Loss of anticoagulant proteins
- Increased levels of procoagulants
- Endothelial dysfunction, and hyperlipidemia
-
Hypovolemia effect on GFR:
- Reduced effective filtration pressure
- Diminished hydrostatic pressure in glomerular capillaries
-
Nephritic Renal Edema:
- Increased permeability in glomerular capillary wall
- Sodium retention
- Activation of Renin-Angiotensin-Aldosterone System (RAAS)

-
Reduced Glomerular Filtration Rate (GFR) in Nephritic Syndrome:
- Decreased glomerular membrane permeability
- Fluid retention and accumulation of nitrogenous waste
-
Primary Hypocorticism:
- Skin hyperpigmentation
- Diminished cortisol negative feedback results in massive rise of MSH/ACTH which causes brown discoloration of the skin
