本文介绍以聚四氟乙烯管替换大部分犬尿道的初步观察结果。实验方法:取12只雄狗,体重18～25公斤。术前先给以 Combelene,然后由静脉注射戊巴比妥作麻醉诱导,并以氟烷-笑气-氧气的混合气体维持麻醉而不给以肌肉松弛剂。作3～8厘米长的阴茎腹侧正中 This article describes the initial observation that polytetrafluoroethylene tubes replace most of the dog’s urethra. Experimental Methods: Take 12 male dogs weighing 18 to 25 kg. Combelene was given before surgery and then intravenously injected with pentobarbital for induction of anesthesia. A halothane-nitrous oxide-oxygen mixed gas was used to maintain anesthesia without administering a muscle relaxant. For 3 to 8 cm long ventral penis
