Dd had one of these Friday and an indirect cystogram to look for kidney reflux. She has a condition that affects her kidneys but my understanding was it was to test for reflux due to her kidney infections.
However I stupidly googled it (as dd still seemed wiped out from it all, she has autism and seizures in response to stress as well as the condition so could have been any of those making her seem out of sorts) and found its more to test kidney function? I am now worrying they may be looking for something serious. Should have known to not google !
