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.
