Fetal left kidney multicystic renal dysplasia

Patient's question:

The right kidney of the fetus is approximately 4520mm in size, with clear structure and distinct corticomedullary differentiation. The left kidney of the fetus is approximately 6141mm in size, showing enlargement. The renal structures are not clearly visible, with multiple anechoic areas observed. The smallest is 44mm, and the largest is 2823mm. The walls are thin and smooth, with increased echoes on the posterior wall.
Could you please ask the expert if there will be any impact on the baby's life after birth? (I am currently 32 weeks pregnant.)

Doctor's answer:

Hello, Polycystic Kidney Disease (ADPKD) is the full name of Autosomal Dominant Polycystic Kidney Disease, which has two types: adult and infant. Infantile Polycystic Kidney Disease: All cases are inherited in an autosomal recessive manner and are accompanied by liver lesions. Although it is mainly seen in children, it can also occur in adults. The kidneys of affected individuals are enlarged while maintaining their external shape. The surface is smooth, but the fetal lobulation is more pronounced. The renal section appears honeycomb-like, filled with small cysts. The portal area of the liver is dilated, and the surrounding connective tissue is increased. The typical presentation is bilateral kidney enlargement or unilateral kidney area enlargement at birth. Due to the dialysis effect of the maternal placenta at birth, blood urea nitrogen levels are normal, but they gradually rise a few days later. Most affected infants die within two months, although some may survive until the age of 10. In summary, there is still a lack of specific treatments for this disease. Traditional Chinese Medicine has shown some efficacy in controlling the progression of this disease in certain cases, shrinking cysts, improving renal function, and alleviating corresponding symptoms. The types of polycystic renal lesions in fetuses are diverse, with varying etiologies and clinical outcomes. It is recommended to carefully differentiate the types of fetal renal cysts before birth. I suggest you go to a specialized hospital for fetal assessment to determine if pregnancy termination is necessary. Otherwise, this is a painful disease for your child.
