Pathophysiology of End-Stage Renal Disease

Predisposing Factors: Precipitating Factors:

infection

Acute inflammation and damage Permeability of capillary


Pyelonephritis

Cell proliferation

Repeated Inflammation

Stage 1. GFR(>90mL/min/1.73m2)

Ischemia, nephron loss, shrinkage of kidney

Decreased renal blood flow

Decreased renal reserve Stage 2. GFR((60-89 mL/min/1.73 m2)

Damage to nephrons

50 % damage

Stage 3.
GFR (30-59 mL/min/1.73 m2)

>75% damage

Renal insufficiency

Remaining nephrons undergo changes

Remaining nephrons filter more solutes

Hypertrophy of remaining nephrons

Stage 4.
(15-29mL/min/1.73 m2)

Stage 5. END STAGE RENAL DISEASE
