Hello new to this forum, my son was born with a enlarged bladder and is now 3.5 mos. We've be trying to narrow down the cause with his urologist he is catheterized 3x daily. Recently he was diagnosed with an enlarged bowel. He urinates on his own daily and also has reg bowel movements. Vcug was good no obstruction but bladder held around 10oz. MRI was done with no findings of back. Ultra sound was done recently and kidneys are great. So far we've heard lazy bladder,neurogenic bladder, non neurogenic neurogenic bladder, hershprungers, mitochondria. Yesterday we had a rectal biopsy done it will be a week for that. We are very concern because we don't have any real answers. Our little guy is 17lbs he is very alert and you would never no any of this by looking at him to date he has had no infections or illness due to these issues but ????? Any type of answers or advice would be very much appreciated.
