Ureteral structure and ultrastructure. Part IV. The dilated ureter, clinicopathological correlation.

The potential of electron microscopy in the study of ureteral dilatation is seldom exploited but ureteral biopsies from 29 congenitally dilated ureters were examined under light and electron microscopy. A correlation between the pathological findings and the result of the surgical correction of these ureters is shown. The prospects of ureteral functional recovery can be predicted when the muscle cell integrity is considered.
