Acute Vasomotor Nephropathy
Etiology

Inadequate blood flow to both kidneys (shock).
Pathogenesis

The condition is reversible.,
Epidemiology

Frequent complication of shock.
General Gross Description

The renal cortex is pale and the medulla is dark and congested.
•Examples:
General Microscopic Description

The tubular epithelium, especially of the proximal tubules undergoes necrosis and sloughs into the tubular lumens. These cells degenerate into amorphous clumps sometimes seen in more distal portions of the nephron as granular pigmented casts.
The vasa recta are congested and accumulate increased numbers of white cells.
