A comparative study was undertaken to investigate the Nd:YAG and CO2 laser systems for laser-assisted vasovasostomies (LAVs). In 32 rats 64 vasovasostomies were performed, either conventionally sutured (CSV) or laser-welded (LAV-CO2 and LAV-Nd:YAG). Postoperative investigations included patency tests, gross examination, light and electron microscopy. The highest rate of sperm granulomas (50%) and the lowest patency rate (50%) was seen in the LAV-Nd:YAG group. LAV-CO2 showed the lowest rate of sperm granulomas (12.5%) and had a patency rate (82%) which was comparable to that of CSV (88%). Laser-assisted vas anastomosis is time saving and technically easy to perform. Contrary to microvascular anastomoses, where both laser types offer the same results, vas anastomosis is better done using a CO2 laser system.
进行了一项比较研究，以调查用于激光辅助输精管吻合术（LAV）的钕：钇铝石榴石（Nd：YAG）和二氧化碳（CO2）激光系统。在32只大鼠中进行了64次输精管吻合术，采用传统缝合（CSV）或激光焊接（LAV-CO2和LAV-Nd：YAG）。术后检查包括通畅性测试、大体检查、光学显微镜和电子显微镜检查。在LAV-Nd：YAG组中，精子肉芽肿发生率最高（50%），通畅率最低（50%）。LAV-CO2组的精子肉芽肿发生率最低（12.5%），通畅率（82%）与CSV组（88%）相当。激光辅助输精管吻合术节省时间且技术上易于操作。与两种激光类型效果相同的微血管吻合术不同，输精管吻合术使用CO2激光系统效果更好。
