To evaluate the role of polytetrafluoroethylene (Gore-Tex) as a ureteral substitute in dogs after resection of a 5 to 8-cm-long middle segment.
Five mongrel dogs underwent resection of the middle segment of the left ureter and segmental replacement of the resected part with segments of Gore-Tex over a double-J catheter. The double-J stents were removed at 21 days and the dogs were evaluated by excretory urography and abdominal ultrasonography 12 weeks after surgery. They were then killed and the ureters and the kidneys examined both grossly and microscopically.
There was radiologic evidence of advanced hydronephrosis on the left side in all 5 dogs. Grossly, the left kidneys showed marked pelvic and proximal ureteral dilatation and atrophy of parenchyma. Severe stricture at the anastomotic sites and marked fibrous tissue around the prostheses were found. No cellular lining was found in the Gore-Tex lumen.
There is no potential for ureteral replacement by Gore-Tex tube graft.
评估聚四氟乙烯（戈尔特斯）在切除5至8厘米长的中段输尿管后作为犬输尿管替代物的作用。
五只杂种犬接受了左输尿管中段切除术，并用戈尔特斯段在双J导管上对切除部分进行节段性替代。双J支架在21天时取出，术后12周通过排泄性尿路造影和腹部超声对犬进行评估。然后将它们处死，对输尿管和肾脏进行大体和显微镜检查。
所有5只犬左侧均有晚期肾积水的放射学证据。大体上，左肾显示肾盂和近端输尿管明显扩张以及实质萎缩。在吻合部位发现严重狭窄，假体周围有明显的纤维组织。在戈尔特斯管腔内未发现细胞内衬。
戈尔特斯管移植不能用于替代输尿管。
