title: A contribution to the study of kinetics of ureteral urine passage in children.
abstract: For the assessment of ureteral urine passage in children sequential scintigraphy with an analyzing system was used. Through the proper division of the time of examination into short time intervals the information on the areal distribution of urine was obtained, dependent on time. After demarcation of the spheres of interest by light-pen, the level of radioactivity was followed continually in a form of curves. Information for the assessment of etiopathogenesis of the disease was selected from the memory system of the device. Through the radioisotope examination also the dynamic changes have been recorded, not visible in excretion urograms, or only presumable from them. The method of examination described can help to assess the functional importance of morphological findings.
