Scanning electron microscopy of the ureters in children with obstructive ureterohydronephrosis

摘要

With the aim of scanning electron microscopy different parts of ureter in reflux and obstructive ureterohydronephrosis in the children has been studied. The differentials consisting in preserve of architectonics of distal parts of ureters in reflux ureterohydronephrosis were revealed. It was shown that a common structure of the ureter remained in this pathology. The differences in structures of distal and proximal parts of ureter expressed in the changes of inflammatory character and violation of safety epithelial layer, edema, inflammatory infiltration of lower layers, especially tunica muscularis. In the proximal part of ureter the wall became thin, because all layers became more thin, especially tunica mucosa and tunica muscularis.
