Renal agenesis is because of all except
Renal agenesis is a condition in which a newborn is missing one or both kidneys. Unilateral renal agenesis (URA) is the absence of one kidney. Bilateral renal agenesis (BRA) is the absence of both kidneys. Renal agenesis happens in the womb when one or both kidneys do not develop. It is estimated that one baby in a thousand is born with only one kidney. However, it is very rare that both kidneys do not develop. Development of Kidney: Secretory pa of kidney:derived from metanephrons/metanephric blastyma Collecting pa of kidney:derived from ureteric bud
Defective development of nephritis tissue
Failure of fusion of ureteric bud with metanephros
Failure of ascent of primitive cells
All of the above
