["Suspended" segmental replacement of the ureter using the ileum. Experimental results at five years (author's transl)].

Segmental replacement of the ureter using an intestinal segment has given good long term experimental results. Preservation of the pelvic ureter has two advantages:--The use of a short intestinal loop, which decreases the secretion of mucus, stagnation and electrolyte reabsorption;--preservation of the normal uretero-vesical junction, thereby avoiding reflux. At the beginning of this experimental study, it was feared that the pelvic ureter would become obstructed by mucus and that the insufficiently contractile and atonic ileal loop would dilate, forming a "pool" of stagnant urine. In fact, no such complications were seen.
