My doctor told me that my baby's u/s was fine except for a mild case of pyelectasis about 5mm- 6mm. Although it is a common finding in boys what worries me the most is that it is a soft marker for Down syndrome. I'm not sure what the term "soft marker" means but now I have to see a specialist in my next appointment and I'm just worried sick. All I ever asked for is a healthy baby. Any other mommies going through this? Or have any information on this? Id appreciate it. Please keep my little Lorenzo in your prayers.
