renal hypodysplasia

Friday 9 February 2007

Definition: Renal hypodysplasia (RHD) is characterized by reduced kidney size and maldevelopment of the renal tissue following abnormal organogenesis.

Renal hypodyspasia associates bilateral non-obstructive renal dysplasia (BNORD) and bilateral non-obstructive renal hypoplasia(BNORH).

Renal hypodysplasia is characterized by a decrease in nephron number, a small overall kidney size, and a maldeveloped renal tissue.
