At 20 week ultrasound, the baby's kidney showed renal pelvis dilation with calyceal dilation at 6 mm for both kidneys. There was no blockage in ureter. Opinions?

No question here: If you are asking "is there blockage in the ureter?" then the answer is possibly. Significant dilation in early gestation increases this risk. It is important to know that dilation (hydronephrosis) can occur without obstruction as well. If the amniotic fluid is low, see a pediatric urologist for prenatal consultation, particularly if you are having a boy (risk of urethral obstruction is high). ...Read more

Hi, My wife is in her 28th week of pregnancy and recent scan shows problem with the fetus kidneys. One of the kidney has multiple cysts and other kidney shows dilation. The reports says:

The fetal right kidney measures 52mm in length, shows dilation of p

Cystic kidneys: Sounds like either ARPKD ( Autosomal recessive polycystic kidney disease) or renal dysplasia due to obstructive uropathy. Both these conditions are compatible with life depending upon fetal lung maturity. Believe it or not-- you need normal kidneys for lungsto develop in utero. In any case my best advice to you would be to consult with a Pediatric Nephrologist, before the birth of the baby. ...Read more

Persistence or actual enlargement of kidneys over time can mean a blockage in the system.This will be evident on other studies and an US obtained after birth. ...Read more

Ct of abdomen- granular high attenuation material in both kidneys. Multiple stones in each kidney. Uniform attenuation in liver. What does this mean?

Hard to be sure...: The description "granular high attenuation in kidneys" is not descriptive enough to know what the radiologist definitely meant.

The phrase "uniform attenuation in the liver" is another way of saying nothing abnormal seen in liver. ...Read more
