My daughter is two years old and has had kidney reflux since birth. The catheter may be used for doing a test called a VCUG which will determine if reflux does exist and to what degree the reflux is. Kidney reflux is a situation where the urine will drain out of the kidney, into the bladder, but if the ureaters are not working properly, the urine will kick back up into the kidneys. This can cause scarring in the kidney and the ultrasound will help to determine if scarring has occurred within the kidney.
Please contact me directly if I can help you out further.
