Deficient metanephric blastema--a cause of oligomeganephronia?
The histopathology and morphometric findings in two cases of oligomeganephronia occurring in a fetus and a preterm infant are reported. Metanephric blastema was decreased in the kidney from an 18-week fetus and was absent in the kidney from a liveborn preterm infant of 33 weeks gestation. These findings support the hypothesis that a primary deficiency of metanephric blastema may be a pathogenetic mechanism of oligomeganephronia.
