Evaluation of ileum interposition in ureterosigmoidostomy: experimental studies.

Experiments in juvenile house pigs with a valved uretero-ileosigmoidostomy were performed, and the advantages of this procedure as against common methods were assessed. Postoperative studies up to 6 months revealed encouraging results in respect of function, infection rate, kidney function, serum electrolyte pattern and as to macro- and microhistological appearances. The results were considered superior to those obtained by simple ureterosigmoidostomy as shown by control groups.
