Ureteral substitute by fallopian tube. Experimental study

Experimental replacement of a long ureter segment in female dogs was done, using the animal's fallopian tube as a pedicle graft. 3 different techniques of proximal and distal anastomosis for urinary tract reconstruction were performed on 3 groups of dogs. The findings suggest that the fallopian tube is a good ureteral substitute, because of its: 1) host compatibility, 2) anatomic proximity to the ureter, permitting blood supply to the tube, 3) mucosa lining which is unaffected by contact with urine and which does not absorb urinary electrolytes, and 4) muscular wall with peristaltic activity. author's modified
