title: [A study of the lower urinary apparatus using 105 mm ampliphotography (author's transl)].
abstract: The exploration of the lower urinary apparatus was carried out using a 105 mm ampliphotography system. 230 examinations were performed according to several techniques: descending and micturition cystography; urethrocystography or retrograde and voiding cystography; cystography with suprapublic puncture; and cystometrography. An analysis of the results enabled an evaluation of the method. The morphological study may appear inadequate if electronic enlargement is not employed. The dynamic study is excellent in the diagnosis of diseases of the neck and uretheral stenosis. The limits of the amplifier field should not lead to a failure to recognize a possible vesicoureteral reflux. A decrease in the exposure dose makes it a technique of choice in children on the condition that the rate of exposures is not excessive and electronic enlargement is not performed too frequently.
