Kidney dysplasia may be a condition during which the interior structures of 1 or both of a fetus’ kidneys don't develop normally while within the womb. During normal development, two thin tubes of muscle called ureters grow into the kidneys and diversify to make a network of small structures called tubules. The tubules collect urine as the fetus grows in the womb. In kidney dysplasia, the tubules fail to diversify completely. Urine that might normally flow through the tubules has nowhere to travel . Urine collects inside the affected kidney & forms fluid-filled sacs called cysts. The cysts replace normal kidney tissue and stop the kidney from functioning.
Kidney dysplasia can affect one kidney are both kidneys. Babies with severe kidney dysplasia affecting both kidneys generally don't survive birth. Those who do survive may have the subsequent early in life:
blood-filtering treatments called dialysis a kidney transplant
Children with dysplasia in just one kidney have normal kidney function if the opposite kidney is unaffected. Those with mild dysplasia of both kidneys might not need dialysis or a kidney transplant for several years.
