Prenatal Hydronephrosis

From the research I have done and the very limited information I received from the Dr. office I think this may be the issue. Apparently it's the most common problem found on prenatal scans with about 42,000 each year. Half of those turn out to be nothing but the other half has a variety of diagnoses, most likely an obstruction or a kink in the collecting tube in the kidney( I really wish the Dr. office would have given me proper names for things! I may not know much but I am quite familiar with anatomy and physiology of the human body)
Since my baby's tube is even so slightly enlarged I am guessing that maybe it isn't completely obstructed? I hope it's nothing.
The perinatologist office hasn't called yet to set up and appt. I really wish they'd hurry up because I am stressed out! Anytime I talk to anyone about this kidney thing I start to cry. Even if i start to think too hard about it I cry. I wanna get past this so I can be normal again!!!!
Logically, I tell myself that it's probably nothing and it's extremely minor AND I am going to a very capable Dr. who will be able to give me advise. But the mom in me just worries and feels so sad because there's is something inperfect about my baby. David even said "How are we going to financially manage caring for a child with special medical needs?"
Hopefully we won't have to.

Fortunately my sister went to the same perinatologist during her pregnancy ( because her quad screen showed high probability for Down's syndrome) and she says he is excellent and the staff was knowledgable, besides it's in a very neat facility in Sarasota. At least she''ll be able to tell me where to go.
