What is it?

In renal dysplasia, a problem occurs in early kidney development, resulting in an abnormal kidney. In this condition, kidney normal tissue is replaced with cysts, which are sacs filled with fluids. It can be seen in a set pattern, or randomly within either one or both kidneys. It can be caused due to a genetic disorder or due to maternal consumption of drugs during pregnancy. When only one kidney is involved, usually the baby grows normalls and has no symptoms. If renal dysplasia is bilateral, babies either do not survive or need a kidney transplant.

Signs & symptoms

Renal dysplasia symptoms may include high blood pressure, protein in urine or blood, edema of the legs, face and hands and urinary tract infections.


Renal dysplasia is conclusively diagnosed only through direct assessment by abdominal ultrasound, CT or MRI scan, surgery, or autopsy. Also, during pregnancy, the mother can be diagnosed with oligohydramnios, due to lack of fetus urine.


Treatment depends on the severity of renal dysplasia. Babies with bilateral renal dysplasia usually die within the first few days but if they survive, dialysis is required. For unilateral renal dysplasia recommendations include eating a healthy diet, salt intake restriction, staying hydrated, blood pressure control and avoiding medications such as NSAIDS.
