Attempts to dilate the urethra with metal sounds and to insert a resectoscope sheath with the metal obturator can be traumatizing in patients with urethral stricture or false passage. We describe a simple technique that uses endourological instruments to facilitate insertion of the resectoscope sheath and placement of the post-resection Foley catheter.
对于尿道狭窄或有假道的患者，尝试用金属探子扩张尿道以及带着金属闭孔器插入电切镜鞘可能会造成创伤。我们描述了一种简单的技术，该技术使用腔内泌尿外科器械来促进电切镜鞘的插入以及切除术后Foley导尿管的放置。
