Pre- and postoperative specimens of ileal loops used in transileal ureteroplasty have been taken and ultrastructural modifications concerning the intestinal mucosa with special attention to the epithelial cells are described. The enterocytes undergo significant modifications because of the operation (i.e. collapse of striated border and entrancement of lysosomal inclusions). Contact with the urine brings about osmotic changes of the intestinal epithelium as well as irritation of the capillar endothelium. But most structural modifications observed histologically or by electron microscopy seem to be reversible. 6 months after the operation the histological structure of the ileum in contact with urine again becomes morphologically normal.
