Abstract

In 54 male Sprague-Dawley rats, 108 vasovasostomies were performed. Sutureless laser welding with the assistance of a removable stent was done using a CO2- and an Nd:YAG-laser system. Conventional two-layer microsurgical anastomoses served as controls. The Nd:YAG laser resulted in significantly lower patency rates, with a higher percentage of sperm granulomas; the CO2 laser produced results equivalent to conventional suturing. Sutureless laser welding utilizing a removable stent proved to be a time- and cost-saving procedure for vasovasostomies in the rat.

摘要

在54只雄性Sprague-Dawley大鼠身上进行了108次输精管吻合术。使用二氧化碳激光系统和钕钇铝石榴石激光系统，在可移除支架的辅助下进行了无缝合激光焊接。传统的两层显微外科吻合术作为对照。钕钇铝石榴石激光导致通畅率显著降低，精子肉芽肿的百分比更高；二氧化碳激光产生的结果与传统缝合相当。事实证明，利用可移除支架的无缝合激光焊接是一种在大鼠身上进行输精管吻合术时节省时间和成本的方法。
