Renal hypoplasia is a developmental anomaly in which one or both kidneys (unilateral or bilateral renal hypoplasia, respectively) have a deficit in the number of nephrons and may be small. Oligomeganephronia represents a severe variant of hypoplasia in which nephron number is reduced by 80% and nephrons are markedly hypertrophied.
Biomarker and diagnostic research for renal hypoplasia has been reported in the published literature.
Estimated prevalence: Unknown (Unknown prevalence).
