[Structural and functional correlations in dysectasias of junctions at various sites]

On the basis of previous studies by means of urography, renography, cholangiocholecistography, possible analogies are sought after in the behaviour of several junctions such as upper and lower uretheral, cholecisto-choledocical, eosophago-cardial. Some significant patterns were found to be in common, or close relations, among the various syndromes.
