[Uro-enteric prostheses: voiding activity and morphological changes of epithelium (author's transl)].
Ultrastructural findings in epithelium of human entero-urinary grafts are presented, five and ten years after intervention. Severity of changes seems to be in relationship with functional defects of grafts, chiefly as voiding is concerned, more than with the duration of implantation and the presence of a sphincteric control. As a matter of fact, as far as an active, regular, complete voiding is obtained, only slight late changes occur in ultrastructure, while flattening of macrovilli and cohalescence of cryptae are early findings. Anyhow, no favorable effect is to be expected from these epithelial changes in order to prevent absorption and/or secretion.
