Detailed explanation-1: -Multicystic dysplastic kidney (MCDK) is a condition in which one or both of a baby’s kidneys do not develop normally while the baby is growing in the womb. Fluid-filled sacs, called cysts, replace normal kidney tissue and prevent the affected kidney from working.

Detailed explanation-2: -The kidneys develop between the 5th and 12th week of fetal life, and by the 13th week they are normally producing urine. When the embryonic kidney cells fail to develop, the result is called renal agenesis.
