X-ray changes in the kidneys of children with orthostatic proteinuria.

In 38 patients with orthostatic proteinuria (O.P.) and in 31 children of the control group (C) roentgenograms of excretory urography have been compared, made in the standing erect and in the lying down posture. In children with O.P. significantly more frequent and more expressive ptosis of the kidneys during orthostasis was found than in the controls. In children with O.P. disturbed urine outflow was found in 36.8%, while in children of the control group only in 3.2%. On the basis of the results obtained relations between haemodynamic changes in ptosis of the kidneys, disturbed urine outflow and the origin of O.P. are analysed.

Some indication fields of radioisotope examination of the kidneys and ureteral urine passage in infants.

This study presents a view of the knowledge the authors have gathered during 11 years of work with radioisotope examinations of the kidneys and ureteral urine passage performed in 34 children. As an important indication field they consider the conditions where excretory urography or separate functional examination, respectively, was impossible to perform or was otherwise contraindicated (anuria, uremia, coma, poor general condition, allergy to X-ray contrast substances, etc.). Scintigraphic examination is indicated even in cases where excretory urography fails to demonstrate filling of the kidneys and, on the basis of X-ray picture, it cannot be concluded whether it is a case of monolateral afunction, marked hypofunction or complete agenesis of the kidney. As the most suitable methods they consider phase scintigraphy of the kidneys together with simultaneous examination of particular parts of the kidneys and urinary passage by means of an analyser device for evaluation.
