Experimental Reconstruction of Ureters Ry Surstitution of Small Rowel Segments

Some uses of an isolated loop of ileum in genito-urinary surgery

“…McLean and Fais (1952) substituted the whole of one or both ureters in dogs by a segment of ileum with ileovesical anastomosis and noted no significant changes post-operatively in the plasma-chloride or carbon-dioxide-combining power. Similar results were obtained in dogs by Davids and Lesnick (1953) and by Annis (1953). Tasker (1953) reported the construction of an opened loop of ileum and its insertion as a flat graft into the dog's bladder.…”

Ureteral Substitute by Fallopian Tube

“…Experimental utilization of biological substitutes of the ureter have in cluded veins [15], arteries [17], fascia [11], abdominal wall [6,18], skin tubes [3,19], intestinal tract [1,5,13] and fallopian tube without success [16,19], Inert substitutes have included tubes of vitallium [10], tantalium [12], polyethylene [7], polyvinyl [21], silicon [3], Dacron and Teflon [20,21]. All of these failed to reestablish long-term urinary tract continuity.…”
