Introduction
A key histopathological feature of fetal renal cystic dysplasia is initial tubular alterations, along with cartilage degeneration. Complete unilateral renal dysplasia may be asymptomatic. In renal cystic dysplasia, the majority of renal defects are bilateral, suggesting that genetic mutations play a substantial role in normal kidney development.
Fetal multicystic dysplastic kidney (MCDK) is a congenital developmental disorder, typically unilateral and associated with segmental stenosis of the renal collecting system; severe cases may be life-threatening.
What is fetal multicystic dysplastic kidney?
Most affected individuals are diagnosed via ultrasound, which reveals an abdominal mass and loss of normal renal architecture, replaced by irregular, large cysts. Renal function in the affected kidney is impaired, often accompanied by ureteral obstruction and other symptoms.
A key histopathological feature of fetal MCDK is early tubular abnormalities alongside cartilaginous metaplasia. Complete unilateral renal dysplasia may remain asymptomatic. In contrast, bilateral renal involvement is common in MCDK, suggesting that genetic mutations play a significant role in disrupting normal kidney development.
During the first trimester (first three months of pregnancy), fetal growth is relatively slow. Pregnant women may consume dry foods such as crackers, steamed buns, or bread. If nausea and vomiting are severe, intake of alkaline foods—such as vegetables and fruits—should be increased to help prevent acidosis.
During the second trimester (months 4–7), fetal growth accelerates, necessitating a more nutrient-dense diet—including eggs, milk, lean meat, fish, legumes, fresh vegetables, and fruits.
During the third trimester (the final two months before delivery), dietary variety should be expanded to include refined grains, whole grains, soy and soy products, animal-source foods, vegetables, and fruits. A balanced and diversified diet helps broaden nutritional sources.
We hope the above information is helpful. Wishing you a happy and healthy life!
