Good evening! We're going to nephrology with our son. The child is 2 years old. Tell me, who brought what? I kind of made a list. But maybe I forgot something or does anyone have any life hacks?))) Especially interested in the question: Contrast for X-ray and the X-ray itself. How was the contrast given and how did the X-ray go?
