Definition: Congenitally small kidney (below two standard deviations below the expected mean) that lacks evidence of parenchymal maldifferentiation (renal dysplasia) or of acquired disease sufficient to explain the reduced size.
Types
segmental renal hypoplasia (SRH)
unilateral renal hypoplasia (URH)
bilateral renal hypoplasia (BRH)
