Hi Trish! Sorry Joel has been through this too, well and truley is the pits eh? Well we were back at the hosp today (doing Hospital in the Home, so just a trip to see the paed) and we werer a bit more demanding. Gotta have another U/s in the next couple of days. Paed finally admitted that he has been practising since 1973 and seen nothing like it, so no one knows really. He spoke to the paed urologist in Brissie though who said that if it is an abscess (cos they don't really know what it is!) then yeap it will need surgery. Poor Ned though, his bum is red raw from diarrehea from the ABs. Let me know how Joel goes with the next scan.
