Hi doctor, my daughter is 34 weeks pregnant. the past 2 ultrasounds showed baby had sl. enlarged kidney. is it a serious matter?

Fetal ultra sounds: The OB doc will follow it, and depending on how it progresses or if it does nto progress in size, the OB should discuss this with ur daughter. Sometimes hydronephrosis is picked up this way. As long as hte kidneys are functional the baby shoudl be okay.

Possibly: Urologic abnormalities are found in 3%of pregnancies. Most abnormalities do not correlate with function. The most important question is there enough amniotic fluid. The fetal urine is the amniotic fluid and if it is low that would suggest poor kidney function and possibly poor lung development. Large kidneys can be normal, poly cystic kidney disease, mild obstruction among other diagnosis.

Usually not: The enlargement can be the result of hydronephrosis, bladder reflux, normal variant, or rare cystic/solid masses. Most of this should be clarified with ultrasound after birth. The reports you already have should reveal the most likely cause for the enlargement. Ask your ob.
