thanks, will look into that
I'm afraid I don't have an answer for you about the ultrasound, but you may want to ask your doctor about the possibility of using a NON-ionic dye for the IVP. I've had severe reactions to iodine based dyes in the past, but can get away with a non-ionic dye. I do typically still pre-medicate with benadryl, as a precaution, but I've not had any trouble with the non-ionic dyes.
Best of luck.
