A histologic study of the vas ends was carried out in 21 patients undergoing vasovasostomy. All had undergone prior vasectomy by the same surgeon, with a technique identical except for the type of cautery used to seal the vas ends. A superior sealing of the vas, as shown by fewer cases of vasitis nodosa and spermatic granuloma, followed use of the thermal cautery ("red-hot wire") than the electrosurgical cautery (23% vs 60.7% suboptimal sealing rate). The thermal cautery is a superior method of sealing the vas at vasectomy.
对21例行输精管吻合术的患者进行了输精管残端的组织学研究。所有患者均由同一位外科医生先前进行过输精管切除术,除用于封闭输精管残端的烧灼方式外,手术技术相同。与使用电外科烧灼相比,使用热烧灼(“炽热导线”)后输精管的封闭效果更好,表现为结节性输精管炎和精子肉芽肿的病例较少(次优封闭率分别为23%和60.7%)。热烧灼是输精管切除术中封闭输精管的一种更好的方法。
