Abstract

The objective of this study was to assess the application of a urethrostomy technique that utilizes an autologous vascularized intestinal graft as a "neourethra" and to analyze its short- and long-term feasibilities. Six cats with urethral rupture and 8 cats with urethral stricture and a history of urethrostomy were included. The inclusion criteria were the indication for urethroplasty and limited urethral length for perineal urethrostomy. A segment of intestine was prepared as a graft for urethral repair. The diameter of the aboral end was adjusted to facilitate anastomosis with the urethra or neck of the urinary bladder. An ostomy was created in the prepubic region using the oral end. The postoperative follow-up period was at least 1 y. Restoration of urinary flow was successful in all cases immediately after surgery. During postoperative follow-up, minimal complications were observed, with urinary incontinence being one of the most frequent, occurring in 28.5% (4/14) of the cases. Urine culture, carried out at different times during the follow-up period, was positive in 72.7% (8/11) of the cats. The autologous graft from the vascularized intestinal segment was an appropriate urethral substitute and this urethroplasty technique therefore proved to be feasible in cats. The postoperative complications observed were not exclusive to this technique and generally could either be corrected or tolerated. Periodic clinical follow-up examinations are recommended. This procedure allows the reestablishment of urinary flow and should be considered a favorable option, particularly when there is insufficient urethral tissue to allow repair using conventional techniques.

猫自体带血管肠移植神经的建立。
本研究的目的是评估利用自体带血管的肠道移植物作为“神经通道”的尿道造口技术的应用,并分析其短期和长期可行性。其中6只猫尿道破裂,8只猫尿道狭窄并有尿道造瘘史。纳入标准为尿道成形术指征和会阴尿道造口术限制尿道长度。制备了一段肠作为尿道修复的移植物。调整输卵管末端的直径,以方便与尿道或膀胱颈吻合。用口腔末端在耻骨前区造口。术后随访时间至少1年。所有病例术后立即尿流恢复成功。术后随访中,并发症极少,尿失禁是最常见的并发症之一,发生率为28.5%(4/14)。在随访期间的不同时间进行尿液培养,72.7%(8/11)的猫呈阳性。从带血管的肠段中取出的自体移植物是一种合适的尿道替代物,因此证明这种尿道成形术在猫身上是可行的。观察到的术后并发症并非该技术所独有,通常可以纠正或耐受。建议定期进行临床随访检查。这种方法可以重建尿流,应该被认为是一种有利的选择,特别是当尿道组织不足,无法使用传统技术进行修复时。
