oligomeganephronia

A condition that may be a subtype of renal hypoplasia, characterized by ↓ nephrons with hypertrophy of remaining nephrons; kidneys are often small, glomeruli are enlarged, as are the tubules, which may become cystic; it is often first identified in early childhood as a cause of polyuria, polydipsia, and growth failure; it is accompanied by a defect in urinary concentration, sodium reabsorption, and acid excretion, often resulting in metabolic acidosis and slow progression to chronic renal failure
