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.
