“…With this in mind, several authors have performed vasovasostomy with the carbon dioxide laser and Neodymium:Yag laser with excellent results [1,4,71. These authors, however, performed vasovasostomy immediately following vasectomy, which is in contradistinction to clinical practice.…”

This is the first arm of a two prong study conducted to learn two different aspects of vasovasostomy in dog vas deferens using the milliwatt carbon dioxide laser. The first study involved the evaluation of patency without collection of sperm. Six dogs were evaluated and all underwent vasectomy and subsequently had vasovasostomies performed between 4 and 12 weeks utilizing two approximating sutures and welding with the milliwatt carbon dioxide laser. Metal clips were used for both X-ray analysis and localization of the vasovasostomy site. In this investigation a vasogram was performed. Dogs were sacrificed at 4, 6, and 8 weeks postvasovasostomy. The vasovasostomy specimens were studied with electron microscopy and histological evaluation. The vasovasostomy was completed in under 120 minutes using this laser-assisted technique and was found to be a viable and promising technique for vasovasostomy.

This is the second study of a two-prong investigation conducted to learn two different aspects of vasovasostomy in dog vas deferens by using the carbon dioxide milliwatt laser. This investigation involves the evaluation of patency and analysis of sperm. Six dogs underwent vasectomy, followed by vasovasostomies performed between 4 and 12 weeks later, utilizing two approximating sutures and welding with the carbon dioxide milliwatt laser. Metal clips were used both for x-ray analysis and localization of the vasovasostomy site. All dogs had pre-vasectomy semen analysis. Following vasectomy each dog underwent ejaculation until azoospermia was obtained. Vasovasostomy was performed and semen was examined. Prior to harvesting, vasography was also obtained. All ejaculates had active sperm noted and 12 of 12 vasograms (100%) revealed patency. The dogs were sacrificed at 4 weeks, 6 weeks, and 8 weeks post-vasovasostomy. The vasovasostomy specimens were studied with electron microscopy and by histological evaluation. The vasovasostomy was completed in under 90 minutes by using this laser-assisted technique. This procedure offers to the urologist a more simplified and reproducible operation that can be performed easily and with a potential decrease in hospital costs.
