Renal agenesis
When there is no meeting of or interaction between the ureteral bud and metanephric mesoderm renal agenesis results. This photo shows bilateral renal agenesis in a posterior view of the abdominal organ block. The adrenal glands, marked with asterisks, normally appear as pyramidal structures capping the kidneys. In this setting of renal agenesis they spread out as oval organs of large dimensions.
