Morphological study of the ureterovesical junction in children

Abstract

Morphological and morphometric assessment of the elements of the ureterovesical junction in children was performed in the present study in different age groups ranging from 24 weeks of gestation to 16 years old. We tried to answer the question whether, in human ontogenesis, there is a period of anatomical predisposition to primary vesicoureteral reflux. The study included 210 urinary bladders with juxtavesical parts of the ureters that had been obtained from routine autopsies. As a result of the study, we showed that provided the pregnancy is uncomplicated there is no inherited susceptibility that would account for reducing or disturbing the development of ureterovesical junction elements. Based on the analysis of our results concerning the anatomy and morphological changes taking place in the elements of the ureterovesical junction in different age groups, one could put forward a hypothesis that anatomical predisposition to primary vesicoureteral reflux occurs in age group II, i.e. between 28 and 37 weeks of gestation. The parameters that define interrelations between elements of the ureterovesical junction and that are considered essential for normal functioning of antireflux mechanism were still observed in age group VI in our study. This suggests that these relations are not unambiguous in children with normally structured and functionally competent vesicoureteral junction.
