Hydronephrosis
Congenital abnormalities of the kidney and urinary tract (known as "CAKUT") account for approximately 20% to 30% of all abnormalities identified in the prenatal period. Defects can be in one kidney or both kidneys.
Because these abnormalities typically cause 30% to 50% of cases of chronic kidney disease requiring renal replacement therapy in children, it is important to diagnose these abnormalities early and initiate therapy to minimize kidney damage, prevent or delay the onset of kidney damage and provide supportive care to avoid complications of end-stage kidney disease.
These diseases can be detected during the mother's pregnancy, through ultrasounds performed by the gynecologist. Once hydronephrosis or dilation of one or both kidneys has been diagnosed, more tests are needed on the baby when it is born.
