Comparison of polypropylene and polyglycolic acid suture in experimental vasovasostomy

A preliminary study upon seven dogs comparing vasovasostomy using polypropylene suture to vasovasostomy using polyglycolic acid suture was carried out. Five of the seven vasa anastomosed with polyglycolic acid sutures were patent wherease none of the seven vasa anastomosed with polypropylene sutures were patent. There appeared to be less vasal inflammatory reaction where vasovasostomy had been accomplished with polyglycolic acid. This study indicates that further investigation comparing these and other suture materials in vasovasostomy is justified. It also suggests that improved results in vasovasostomy might be obtained by the use of polyglycolic acid suture.
