polyhydramnios, distended bladder and mild kidney nephrosis

My daughter was initially diagnosed with idiopathic hydramnios at about 26 weeks gestation.  The pregnancy progressed normally and baby was growing fast.  Now at 37 weeks, new ultrasound finds distended bladder 3x normal, and mild nephrosis.  MRI was subsequently done, and trachea and esophagus are fine, spinal cord is fine.   The fetus is female is approximately 4400 grams.(large baby) She was tested twice for diabetes, and both tests were normal.  She will have ceasarian next week in a level 3 environment.  No diagnosis has been made at this time.  My question is, I have searched the internet until exhaustion reading everything I could.  Nothing I have read is good, in fact, everything has been tragic.  Is this why the doctors won't say anything.  Does anyone see any hope in this outcome?

I did a little reading on this topic.  It seems like 80% of babies wth the severest form are born without abnormalities.  The key seems to be figuring out why the fluid is being overproduced and not absorbed quick enough.  With the second us they seem to be narrowing that down.

I hope and pray your little girl arrives safely and that they will be able to help her to be perfectly healthy.

My thoughts are with you.

Does she have a name?

Not yet, I think my daughter is hesitant now, thinking that this might be MMIH (Berdon Syndrome).  Your reply was most uplifting, thank you.

I was diagnosed with high fluid at 34 weeks. I am very concerned. I am scheduled for an MRI next Friday. What was the outcome in your case?. Beatriz
