Alloplastic replacement of the canine ureter by expanded polytetrafluoroethylene (gore-tex) grafts. Preliminary report.

In 12 female dogs, subtotal unilateral (8 dogs) or bilateral (4 dogs) ureteric resection and replacement by expanded polytetrafluoroethylene (Gore-Tex) prostheses were performed. Follow-up consisted of periodic excretory urographies. Short- and long-term results, consisting of periodic excretory urographies for up to 12 months, are promising and induce further studies with this new type of graft.
