US sonography in renal transplant: what role? Our experience in recent years, together with the literature of the same period, allows us to state that, from the early seventies (1), when our radiology colleagues were the first to undertake the US study of renal transplant, to these days, the technology has undergone fascinating developments and US has, at the same time, experienced a sort of “
