This is the exact problem my angel baby Noah had. But, Noah's was truly the worst case scenario. I agree with the others... Don't google!

We spoke to numerous Dr's abut Noah's condition from different hospitals all around the country. IF the issue was solely with his bladder he would have survived. Noah had a blocked urethra (LUTO) as well as damaged kidneys, and small lungs which was a result of the large bladder taking up so much room in his little body and not allowing enough room for his lungs to grow properly. He couldn't survive because of the damage to his kidneys as well as the small lungs. Mind you, Noah's bladder was noticeable even to me on the ultrasound.
I am sure your baby is going to be fine. Sending you loads & loads of hugs. Please know I am here if you ever need to ask any questions.
