Hello

Thanks for the query

It looks like your son is having a pelvi-uretric abnormality commonly called as puj. Most often it is congenital detected only later in life. There is nothing to be alarmed about.
Here is how you should go about it

1. ultra sound of the kidney is not a very good modality to note puj abnormality, you must get a ct scan of the kidney ureter and bladder to have a better view of the pelvicalycleal system
2. once the ct scan is done get a dtpa renogram, this test will tell us how well the kidney is functioning
3. if the kidney is functioning well then you will be referred to a urologist where he will advice you corrective surgeries (if required). Mild dilatation is most often medically managed, few puj abnormalities get corrected on its own once the child grows

I am sure you have several doubts, please get back to me so that I can help you

Regards
