Ureteral reaction to suture material.

Dog ureters were anastomosed end to end using either chromic catgut, polyglycolic acid (PGA), polyglactin-910, or polypropylene sutures. Analysis of luminal diameters, fibrosis, scar vascularity, and inflammatory reaction four and seven months later indicated that in ureters of the uninfected dog the best results were obtained with polyglycolic acid. Ureters anastomosed with catgut gave results that were slightly less acceptable.
