Renal atrophy refers to a shrunken small appearance to the kidneys usually due to a secondary cause which contrasts with renal hypoplasia which is the term given to a congenitally small kidney.
Renal atrophy can be unilateral or bilateral dependent on the cause and when unilateral, the left kidney is thought to be more affected 2.
