Prominent Renal Pelvis in 25 Week Fetus

11/30/2011

Question:

Can you please let me know what does it means "prominent renal pelvis" which identified in 25 week fetus, in sonography test?

Answer:

A "prominent renal pelvis" is one of the most commonly seen abnormalities on prenatal ultrasonography. It can range from a mild variation of normal with no long term consequences or in rare cases could indicate a blockage of the kidney. No prenatal intervention is typically indicated. A follow-up third trimester ultrasound can be helpful to see if the condition persists and may need further testing done after birth. On occasion, a consultation with a pediatric urologist after birth is appropriate to further evaluate the kidney. Your pediatrician can make that decision based on the findings of the third trimester ultrasound. The vast majority of the time, the condition is self-limiting and does not cause harm to the developing kidney or infant.
