I think it’s better not to rush for reimplementation because you have a good functioning right kidney, I would prefer to do MAG3 rather than DMSA scan as well as you don’t have a reflux. If the curve is showing an obstruction of the right UVJ go a head with the reimplementation, if not, then you have a diagnosis of non-obstructing non-refluxing HUN, in this case you just observe the baby with no surgery…. Very important point is to make sure that this baby does not have a PUV ( I am not sure from the name is he or she). Good luck
